My experiences with Ebike Solutions: Test report by Dietrich from Winsen


EBS Climber V2 250W Pedelec Rear Wheel Conversion Kit

 Experiences with Ebike Solutions: Trekking bike with Climber V2 conversion kit


We had the idea to deal with electrified bicycles when, during a holiday in Schleswig-Holstein, we were irritated by the strong headwind and got two pedelecs for a day. Two important insights came out. An off-the-shelf pedelec is not as comfortable as your own bike, which you have optimized over many years, which makes it unattractive. My wife then researched whether there were other possibilities for electrification and see there they were. This was the birth of the idea “We convert our bicycles into pedelecs“. But why EBIKE Solutions? The online configurability in combination with the available documentation was the trigger to try this supplier at least once.

Building up Knowledge in Advance

Now we had chosen a first supplier, but we had not decided yet. We had to decide which material to use and if we were able to do it ourselves. Further research on the EBS website brought further explanations and also e.g. the assembly instructions. The study began. How do I rebuild my ORTLER Vienna and the bicycle of my wife a CUBE Delhi then. We also became active on Youtube. The videos helped us to understand e.g. how to remove a square drive, which tools you need and what to consider. This led, among other things, to the fact that we changed the crank drive during the conversion – if you already have the rental tool at home. We learned to understand what a Shimano Deore 3x9 drive is and that the new rear wheel from EBS already comes with a 9 cassette – easy to select in the online configurator. Still, before you spend that much money, I thought I should call EBS in Heidelberg. You get an impression of a company relatively quickly. The conversation lasted a bit longer, because the nice employee provided us with a lot of tips during the phone call, which made the subsequent configuration even easier for me. Then we decided on EBS and it was ordered.

The Delivery Arrived

Well, it was holiday time and bicycle fair. The delivery didn't come the next day, but if you wait for such a kit, every day will count. Everything was there, inside and complete. The rear wheel was spoked, the 9er drive set installed. The assembly instructions for the luggage and the operating instructions for the display were missing. A luggage can also be assembled without instructions, but a configurable display without documentation is of course not that easy. A short call to the support brought the explanation. “The V2 system is brand new and the documentation is not quite finished yet“. On the same day I had a preliminary version of the manual in the e-mail.

The Assembly and Small Hurdles

The kit is structured and documented. The electrical plugs are unmistakable. I would therefore like to deal with points that were relevant for me during assembly.

The PAS Sensor

Although I installed a 4-edge drive in my ORTLER Vienna, the magnetic disk did not fit on the axle. The reason was the available space between the smallest sprocket and the frame. The colleague from the support had recommended me to install the PAS sensor on the right side and to use the professional version, because the magnetic encoder is better protected on the right side. After I discovered that the magnetic disk did not fit, I ordered a Hollotech II sensor for 26Zühne that fitted perfectly to the smallest sprocket by magnetic adhesion and delivered the other sensor. Then came the next Hüdde. My bike has chain goggles. This metal part is shaped and prevents the PAS sensor from lying flat. Here had to be helped with the file and the metal scissors. The result is great, the gap between magnet and sensor is less than 3mm.

Rear Wheel Installation


 Experience with Ebike Solutions: CGIG electric motor  Experience with Ebike Solutions: CGIG electric motor


Of course, the 12mm wide axles did not fit into the dropouts, so why not? The previous rear wheel was fitted with a quick release. To top it all off, we also have a hitch on our bikes on the axle, as our dog is also on tour. It was therefore necessary to work the dropouts with a flat and round file with extreme care. Although the small noses of the torque rods fitted 100% into the dropouts, I ordered torque rods from EBS for myself and my wife's bike. These were then also installed in both bicycles. The brake disc was taken from the old rear wheel and fixed with 6Nm and Loctite. I had bought myself in addition extra a small torque screwdriver. After the clutches were bored out to 12mm, the whole construction could be screwed. Left with torque wrench and 45Nm, right with torque right upper arm. All secured with Loctite.

The Battery Holder

Please don't get the idea and try to disassemble the battery holder only to countersink the four screws. I thought it would work, but then you can't get the upper part into the luggage, because the battery lock is in the way. Also EBS' suggestion to try an Allen extended by an aluminium tube is not the way to go. You'd better get a flexible magnet lifter for a few euros at a hardware store. You can use it to fiddle with screws from tight angles and also insert the four screws into the battery holder. To make sure that you can find the batteries right away, simply light them from below with a flashlight. To tighten it I didn't have to hold it from the inside.

The tachometer sensor

It's actually simple, but the distance is crucial. For both riders I put a tape of electronic mat under the sensor and made sure the distance was less than 3mm. That was’it actually.

The Test Ride

 Experiences with Ebike Solutions: Trekking bike with Climber V2 conversion kit

5 levels are programmed from EBS. The first stage with 14% is class for starting. The 14% corresponds to about 48Watt. But with the conversion kit of my wife a new display was delivered. There the stage 1 was programmed with 120Watt, which is much too much for a start or easy gliding. EBS contacted us immediately and delivered a new display with a new firmware.

Back to my ORTLER Vienna. Not a lightweight, because I am 2m tall and weigh 110kg. The bike already weighed over 20kg before the conversion, so I was curious how the riding behaviour is. I was very positively surprised. In the largest gear, i.e. on the largest chainring and the smallest rear sprocket, an 11er, the controller gently adjusts at 27km/h and enables me to pedal evenly. The power shown on the display is about 180Watt and this at level 3 (50% power) in the plane. The test drive of my wife on your CUBE Delhi is still pending. This takes place as soon as the new display is mounted and the five support levels are programmed.


The conversion kit was not screwed together in 3h. It is recommended to take time and carefully consider which combination is required. In the same train we had exchanged e.g. a bottom bracket, mounted a bigger chain guard with glasses at my wife, changed the tyres to Schwalbe Marathon and replaced the mudguards of the CUBE. All in all a very good conversion kit with good documentation and very good support from Heidelberg. We kept our two beloved bikes and even upgraded them. The next tour is already planned and I am curious how the biking with the dog trailer (14kg) and our dog (30kg) will go on.

EBS Climber V2 250W Pedelec Rear Wheel Conversion Kit

 Experiences with Ebike Solutions: Trekking bike with Climber V2 conversion kit

Installation of the Climber V2 Retrofit Kit

The Speedster was configured and ordered together with a dealer. At the same time I ordered the long awaited Climber V2 conversion kit together with two batteries (Hi-Power Ebike battery 36V 13.8Ah 497Wh) from EBS. Then the conversion began. The goal was to build a completely (!) STVO-compatible bike that could also accommodate enough battery power for longer distances. The original weight target was 16-17 kg (fully equipped with battery). At least the whole conversion should stay under 20 kg, with all zippers and zippers.

I sent a rim to EBS for the purpose of spoking in the HR engine, for the front wheel rim I bought a Hope-4-Pro hub and had it spoked in by the dealer around the corner as well. Changing the cassette to the new HR-CGI-G hub and removing and installing the Hollowtech II crankshaft bearing was quite simple once you had the right tools. I had to trick a bit when fixing the PAS magnet disc, because my smallest chainring is made of aluminium and does not hold the holding magnets. I simply glued the PAS disc with "FIX All" to the chainring – and finished. With the PAS sensor, however, I had to rumdengeln quite a bit, because it lay too close to the magnetic disk and dragged, but at some point this was also possible.

A big headache for me was the search for a stable and at the same time optically halfway appealing accommodation of the large battery (10s4p with 2.3kg) and the controller. In the meantime I had set myself – to 10s4p with a view to planned longer tours. The official “drinking bottle battery“ from EBS (and other suppliers) is too massive for me. So – I'm looking for a battery bag that can hold not only the battery but also the (quite massive) standard controller from EBS. Finally I bought the Ortlieb Frame-Pack Top-Tube. Since I had read several times that the controller had to be well ventilated, I thought about a controller cooling. For me, the solution was 4 small aluminum tubes from the PC area (35 x 35 x 6mm), which I stuck to the controller housing with heat-conducting adhesive. The controller should then protrude (upside down) from the underside of the frame bag to get the cooling air out. To do this, a correspondingly large opening had to be cut into the Ortliebtasche. So that the whole thing doesn't tear out and the controller still has a firm hold in the bag, I built myself a small controller holder (again from aluminum angles), which was then glued into the frame bag.

Then I had to cut cable glands in the front and back of the bag, which were glued back with a drilled aluminum sheet. The openings are then covered from the outside by a small strip of leather. This is certainly no longer completely waterproof, but should be sufficient for my purposes.

First Driving Experiences with the Climber V2 Drive System


 Experiences with Ebike Solutions: Climber V2 conversion kit  Experiences with Ebike Solutions: Climber V2 conversion kit


In the evening the bike was finished, as it was dark, it was only enough for a first short ride in my settlement – not even the gear display was configured yet.

My first impression: Uuuuuuuuih, it's like a rocket (yaaa – I haven't driven a cougar yet). Anyway, my bike worked at first go, I noticed immediately that the engine is practically unheard of. The fact that the acceleration to values above 30 km/h was almost effortless made me especially happy, whereby I immediately suspected that the prescribed throttling to 25 km/h was not yet activated here (it was 40 km/h, as it turned out the following day). Anyway, I was very impressed with my E-Speedster right from the first pedal movements and still am.

Yesterday afternoon I was relatively late to configure the display a bit. Afterwards I wanted to test the bike a little bit more extensively. The little joyride turned into a real route. Here there were a few gradients, as well as great forest paths and pistes with “Gravel characteristics“. At 22:15 o'clock I stood with almost exhausted first (!) battery (the last beam had started 4 km before) and with 131 km on the day speedometer in front of my house. I was thrilled, but also knocked out, because you still have to pedal a little.

Bicycle Tour with the Climber V2 Conversion Kit

 e-Speedster: the latest trekking bike

The Facts about the Tour:

System weight:approx. 110kg

Selected levels of support:

  • 80% Level 3
  • 15% Level 4
  • Level 2 and 5 only for a short time each
  • Level 1 not at all


Set control speed: At 75% of the distance I chose the pedelec-compliant 25 km/h, at the end of the tour I increased the cut-off value, but to 30 km/h – more about that later.

Average speed: according to display 23 km/h, if I calculate my ¾-hour break out, it should be rather approx. 25 km/h.

Terrain: 85% very flat (Münsterland halt), with the Teutoburger Forest slight (10%) and very few (5%) medium gradients.

Wind: In the beginning quite fresh wind, the corresponding headwind on the voyage was less.

The battery behavior – is determined with the 5-bar display of the display:

  • at kilometre 65,9: first beam gone
  • at km 91.7: second bar removed (shortly before the limit was raised to 30 km/h). Support level was increased to level 4 (very briefly also level 5).
  • at kilometer 112.9: third bar gone (down to kilometer 117 to level 3 – this meant that support could be achieved up to about 23km/h), then back to level 4. This meant that real engine support could be achieved up to a good 26 km/h - even though the 30 km/h limit was set.
  • at kilometer 127,4: fourth beam gone (i.e. last beam broken), level 4 remained set - about 4km to home.

Kilometre 131,2: Arrival at home – last beam still present, not flashing yet.

Condition of the rider: Currently not very good condition at 59 years and 84 kg rider weight. The 131 km were muscular after the ride and still occasionally noticeable today.



 Experiences with Ebike Solutions: Climber V2 conversion kit  Experiences with Ebike Solutions: Climber V2 conversion kit


The engine runs extremely quietly and seems sufficiently powerful to me for the majority of the gradients I aim for.

The bike is comfortable even without a motor, i.e. the freewheel of the CGI-G motor is very useful. A stress-free ride (still without electrical installation) over a distance of 20 km was already possible a few days ago.

Overall, I am very satisfied with my new pedelec and look forward to the coming tours (now certainly with a much larger radius of action) that I want to undertake in summer. Special thanks (no - I don't get paid for that) to Mr. Dietrich and his crew from EBS, because there I always received patient support and some valuable advice - also on the phone. I am very satisfied with the conversion kit supplied by EBS.

My Experiences with Ebike Solutions: Test Report by Hans-Georg from Siegen, Germany


EBS Climber 250W Pedelec Rear Wheel Conversion Kit with CST Engine

 Experiences with Ebike Solutions: Mountainbike with Climber conversion kit


Ladies and Gentlemen,

In March of this year, I bought a pedelec replacement set for my wife's MTB from you. I would like to thank you again for the good advice; the retrofitting has basically worked without any problems.

The bike has been ridden extensively in the meantime. We – especially of course my wife – are enthusiastic. Exactly the solution we had in mind. Cycling as before; support only when it is necessary (when the knee is closed “flabby“). After our first two test drives (added 94 km and 1,250 hm) just 2 segments of the battery indicator were gone. Very large ranges can be achieved, as practical experience has shown on numerous trips. Our impression is that the converted wheel can be driven much more effectively with the help of the engine than a pedelec with a mid-mounted engine; it has a much wider range of transmissions and allows much more sophisticated gear changes. Especially the frame pocket for the battery is ideal for this bike.

 Experiences with Ebike Solutions: Mountainbike with Climber conversion kit

For the torque support, I chose a self-made solution; I replaced a (conical) fixing screw of the disc brake with a screw with a cylindrical head, which is used to insert the metal tab and the wheel axle at the same time. This way I don't have to loosen a second screw when changing a tire.


All in all, this is a change that is highly recommendable.

Friendly greetings,

My Experience with Ebike Solutions: Test Report by Franz from the Allgäu Region


EBS Climber 250W Pedelec Conversion Kit with EBS Pedelec Drinking Bottle Battery 36V 11,6Ah

 Experiences with Ebike Solutions: Climber conversion kit

"Why this Set?

I'm interested in the Climber compared to the standard hub motors I've driven so far. Especially here in general, the engine can be a bit more powerful. The controller integrated into the drinking bottle holder is ideally integrated into the system and I hope that the 11.6 Ah battery has the range I was aiming for. These components are the ideal combination for me - the practical test will show it. Last week I placed the order and today the set was delivered reliably within the stated processing time of 4-7 working days; the engine spoked into a black 26mm rim. My curiosity was great and of course I had to put my nose right into the package.

First Impression: What Stands Out?


  • all completely well padded and secured against slipping, rim even secured with Velcro
  • Motor axle and freewheel well padded against damage
  • all delivered parts are optically perfect
  • detailed assembly and operating instructions enclosed
  • EBS wanted to know which sprocket I was going to drive before delivery for centring reasons. Since I want to keep my 7-speed gear, the Shimano HG 41 7-speed sprocket will be mounted. EBS has included 2 spacer rings to mount the 7-speed sprocket on the 9-speed hub. Great, because otherwise I would have had to get them extra again!
  • Cable ties are enclosed in large numbers
  • The sticker on the battery with Panasonic cells indicates a max. charging current of 2.35 A. This surprises me, as I can charge the Prophete batteries with 3A myself.

The next days I will assemble the set and then start for the first test drive, I am curious!


Interim Result:

Communication with EBS in advance, delivery, packaging with upholstery, goods and instructions are tip top. Actually not better!

Conversion to a Pedelec with the EBS Climber Conversion Kit

Experiences with Ebike Solutions: Climber conversion kit

To begin with, a note: A special puller is required to mount the sprockets due to the thick motor axle. The standard puller does not fit! I have a screw ring puller “on-tremed“, better if necessary still the correct part with order.

Experiences with Ebike Solutions: Climber conversion kit

As expected, the engine fits easily into the frame. This is due to the fact that a hub motor was already installed before. The distance to the frame is large on both sides. However, my frame has no disc brake mounting, so I cannot make any statement about the suitable diameter of a brake disc.

Experiences with Ebike Solutions: Climber conversion kit

The built-in drinking bottle controller is fastened here with 3 screws. With only 2 screws I would have pulled through a clamp for safety. This is of course a matter of opinion. There would still be room between the battery and the holder.

Experiences with Ebike Solutions: Climber conversion kit

The cables between pedal sensor and controller are much too long. I would offer shorter cables, with optional extension if necessary. This means that unnecessary cables have to be attached to the wheel. I was lucky enough to have them disappear into the frame.

Experiences with Ebike Solutions: Climber conversion kit

2 PAS sensors are supplied, one for right and one for left mounting. Which one is the right one, however, was not obvious to me and was also not in the manual. Promptly the wrong mounted… Sensors for mounting with cable ties are normally included, I chose the square version for “professional mounting“. The connection to the motor cable fits perfectly, the supplied extension cable is not needed.

Experiences with Ebike Solutions: Climber conversion kit

I fixed the cable switch to the handlebars with the provided holder. There are 2 brackets with different diameters included. With my thin handlebar I had to put additional rubber strips under the small holder, so that it fits.

Experiences with Ebike Solutions: Climber conversion kit

Positive is that all plugs are provided with arrows and thus the plug direction is given. Also the pressure point is ideal, no weight during assembly, but also not too light. Separation is also possible without superhuman forces! Due to the new rear rim and the change from a rim to a screw ring I still had to adjust the rear brake and the gears - done! Finally: Battery in, electrical test, display adjusted - engine starts turning. Everything works!

Result Assembly:


  • Time requirement approx. 4h (with tire mounting)
  • thanks to the detailed assembly instructions completely unproblematic
  • PAS sensor cable too long, sensors for right and left could be better marked
  • A detailed operating manual also makes setting up the display child's play.
  • everything fits, nothing wobbles or rattles: Great!

Addendum to the assembly: The Bafang Climber does not use a screw ring, but a modern plug-in ring!


 Erfahrungen mit Ebike Solutions: Climber Umbausatz

First Impressions after a Small Starting Lap Around the Village (23 km):

The conversion kit is very powerful from below, quiet and allows a slow mountain tempo at level 1. With a gradient of 14% I am at level 4 “high noise“, even my Greenmover can do it. On the level with level 1 then quite fast on the way. Above 20 km/h the engine is clearly audible and has a somewhat uneven run. From approx. 23 km/h on, higher support levels don't provide any noticeable increase in performance anymore. The maximum support is approx. 30 km/h and is switched off at approx. 0.5 seconds after the pedal stop. At the set maximum speed the pedal is gently controlled (several tested). The freewheel is very quiet. The rim turns somewhat worse than the small Bafang with screw rim.

Experiences with Ebike Solutions: Climber conversion kit

Final Test Drives:

  • 1x journey home from work
  • 2x house round
    (each approx. 45 km and 450 hm, mixed route profile)
  • typ. Height profile
  • Total mileage now approx. 130 km

Conspicuous Features / Additions to the First Impression:

The CST Motor:

The weight of the bicycle is 23.5 kg, ready to ride. The engine is quiet under 20 km/h - even under load! On top it gets much louder with an out-of-round noise. Perhaps this will improve with a higher mileage. At high speeds my small trio engine was quieter. Meanwhile the freewheel is as good as with the trio engine. My protected ideal use is on gradients of up to 15%.

The Controller and Driving with Current Levels:

Unknown to me so far (always drove speed steps until now). The current stage control requires diligent switching of the stages with sporty driving style (1 is enough on level, on mountain 3 to 5). But I think the current levels are much better, especially I can ride comfortably on the mountain with level 1 or 2. Also the starting is much smoother. I missed these characteristics with the old system. Means also: Motor can be driven comfortably on the mountain, but also fast on level 4 / 5. There it bites right! Provided it doesn't fall below 13 km/h on steep gradients. Then the force will decrease considerably and the large current steps will no longer bring any noticeable increase. But if it is kept on trot, it really goes off! The characteristic is äsimilar to my GoSwiss Direktl;ufer. Stage 1 is programmed quite high with 3A, the wheel almost always reaches the maximum speed in the plane. For me in general and as a “fast rider“ o.k., but that would be more comfortable.

Comparison with Own Trio System on Defined Mountain Route

  • tested EBS conversion kit: controller warm to the touch, cold motor
  • Trio comparison system: controller hot, motor warm to the touch


The Battery:

According to a Prophet installer, other manufacturers sometimes overheated a bottle controller's contact with the battery. Reason: A dirty connection to the battery cable. EBS has solved this cleanly, the connection has been reworked and additionally secured (can be seen from below without opening the controller). This source of error is therefore excluded from the outset. As expected, the 11.6 Ah battery with Panasonic cells from EBS has much longer “steam“ than my old 9 Ah trio battery with Samsung cells. Whereby the day temperatures of 13 degrees were not ideal test conditions. I could not notice any difference in the characteristics of the two batteries so far. After my 44 km tour the battery had a protected 1/3 residual charge. If it can do 60 km under my allgäu conditions, I am satisfied. But I still have to test it. The 9 Ah Trio battery will be my Range Extender, with both together there should be at least 100 awesome kilometres in it! The battery can be inserted into the holder without keys and can be charged externally as well as on the bike with a charging current of max. 2.35 A. The battery can be used as a battery charger.

Suggestions for Product Improvements:

  • shorter cables to the PAS sensor
  • Stage 1 with 2A (possibly programmable as customer request?)
  • black battery color as option desirable


 Experiences with Ebike Solutions: Climber conversion kit

Final Result:

The very successful system convinced me completely and is far superior to the previous trio drive. Clear purchase recommendation from me for sporty drivers!"

My Experiences with Ebike Solutions: Test Report by Dr. Rolf B. from Neuss


EBS Folding Bike 250W Pedelec Conversion Kit with Crystalyte Engine

 Experience with Ebike Solutions

"Why did I have My Folding Bike Converted by Ebike-solutions?
Let me tell you the whole story in chronological order:

Catalyst was a capital knee damage left due to a ski accident at a young age. The effects have already been felt in recent years, with enormous pain on the annual bike rides (neighbours, classmates). At the end of 2011, the knee was so damaged that running and climbing stairs became an ordeal. But since I wanted to continue cycling, I thought of a pedelec. But it should be transportable and fit into my plane like my 16“-folder of high quality.

 Experience with Ebike Solutions

Now there were ready to use folding doors, but not with 16“-R” and larger ones, which do not go through my loading hatch, moreover their range specifications were not convincing – so the decision to rebuild the approx. 10 year old folding doors had been made.

The research with the help of the internet was an exciting task: sometimes I had dared to call a shop on a Bavarian lake on a Saturday morning – no, that wouldn't work now, you would have customers, please call me during the week; sometimes I had a wife on the phone – no, the husband wouldn't be available again for 6 to 8 weeks.
At everything was right: A well-structured internet presence and a friendly and competent advice on my first call, which also reflected experience: So you weren't afraid of 16“-Rädern with a narrow fork. So the decision was made.

After making an appointment I went to Heidelberg in the spring of 2012 and handed in my first folding bike on a Thursday for rebuilding (3-step switch, recuperation) and was able to pick it up the following Monday. Since we had planned a bike tour in the Maintal with the neighbourhood for 2012, whereby the longest stage of the day was 56km, I decided to buy a battery 36V with 11,6 Ah.

In the following days I had to find out whether the bike could also master these 56 km with one battery charge. Every day I did a circuit of about 5km. Interestingly, there were two pleasing results: In exactly 2 weeks I drove 102 km with one battery charge and the knee complaints were left after “movement without load“, so that I could postpone the threatened operation with an artificial knee joint for the time being.

The first test came in May 2012 during a bike tour with some former classmates. Riding a pedelec in a group of 8 cyclists was a completely new experience: I was either too fast, or too slow and uninterrupted with shifting back and forth, or interrupting pedalling. This urgently needed to be improved.

Since I was basically very satisfied with the performance, I decided to have the second folding bike at rebuilt as well. After making another appointment I went back to Heidelberg in summer 2012 (I flew to Mannheim and from there with a pedelec team on bike paths) and used this opportunity to upgrade the first converted bike with an additional 6-step switch and a Cycle Analyst computer. This gave me 18 speed levels (3 times 6) and the test with 16 cyclists in the Maintal was a totally relaxed tour: I could adapt to the group speed and enjoy the landscape at any time. The computer showed me important technical performance data. Charging the batteries (for both of them) overnight in the hotel could be done one after the other with a single charger.

Finally, two arguments in favour of the Crystalyte engine: It is strong enough to pull a 60kg trailer – and on this year's neighbourhood tour a neighbour also had a new pedelec with him, but with a mid-engine. Plötzlich striked his hub gear and he could only drive in the lowest gear – a further driving in the group was no longer to be thought of. A big room taxi didn't want to come, so I pushed him with my right arm for the remaining 5 km to the destination, thanks to my strong Crystalyte motor and the big battery."

My experiences with Ebike Solutions: Test report by Helmut K. from Traunstein


EBS Plug & Drive 250W Pedelec conversion kit with EBS Pedelec drinking bottle battery 36V 13,6Ah

 Experience with Ebike Solutions

"Hello EBS Team!
I have just rebuilt 2 bikes and want to report on my experiences:

In my bicycle, a Cycle Concept Bj. 2005, and in the bicycle of my wife, a Cycle Concept Bj. 2000, I built in a set of EBS Plug and Drive 250W conversions. I used a 13.6 Ah (490 W) drinking bottle battery.


After detailed research on the Internet I decided in favour of Ebike Solutions. The reasons were the good control, the well configurable offer, the friendly and competent information of the employees and of course the price. The delivery time was a bit longer than shown on the internet, but with about 2 weeks it was quite reasonable (I had also ordered in the middle of the season). The delivery was neatly packed and complete. The installation instructions from my point of view were fully sufficient. I had to drill a hole in the battery holder for my somewhat older models and do some tinkering when mounting the separate torque mounts. Nevertheless I managed without hectic to rebuild my own bike in about 4 hours and that of my wife in about 3 hours. The wiring was simple, the plugs are unmistakable. Of course there are now more cables on the bike, but everything is perfectly fastened by the cable ties supplied with the bike. I have not installed the brake switches, the reaction time of the drive when starting and stopping is extremely short, so that from my point of view the switches are left.

The driving behaviour we both find simply super! We are thrilled about the fun cycling makes again. In our cosy area in Chiemgau there is simply the possibility to ride on routes you would otherwise avoid. My first 50 km show me that I can probably count on a full battery with a range of 60 to 80 km. In flat terrain there is certainly much more to do. With the drive switched off, the bike feels as if it has not been modified, I can't see any disadvantages. You can hear the engine, but it's not annoying and I had the impression that it became quieter with longer mileage.

Result: I think it's a great thing, my two neighbors are already infected. Thank you EBS Team."

EBS Plug & Drive 250W Pedelec conversion kit with EBS Pedelec saddle battery 36V, 14Ah

 Experience with Ebike Solutions

"Dear ladies and gentlemen,
I have now received my conversion kit from you. I had bought the EBS Plug & Drive 250 Watt with front wheel drive and wanted to give you some feedback.


The installation was finished after 3 hours and there were no difficulties. Exactly as it is described in the manual and on your homepage. After a first extensive test drive (50 km) I have to say that I am completely enthusiastic about the conversion kit. I have already driven many pedelecs: S-pedelecs, pedelecs up to 25 km/h, rear wheel drive, bottom bracket or mid-engine drive, ready built purchase pedelecs with a price up to 8.000 €, etc.
I put the 26 inch engine into a 28 inch rim and am full of praise. Support up to 32- 33 km/h, unobtrusive engine in the front wheel rim, powerful and with the 15 Ah battery version sufficient capacity. The Bafang engine does not get hot even on shorter mountain stretches. What was important to me and what I think is very good: I can adjust the display down to "legal" 25 km/h at any time. Simply a great ride and that for a little more than 1,000 €.

I can only recommend this conversion kit! Enclosed 2 photos, which you can publish on your homepage. Now I buy myself a more high-quality wheel (the current one cost 300 €) and the same conversion kit is bought again and/or obstructed. The stronger EBS Climber drive is not necessary with my system weight (71 kg rider + approx. 22 kg bicycle) and my application profile (mainly flat terrain).

It was the right decision! If now the engine or the drive still passes the long-term test (I hope that the engine and the other components will work the targeted 10,000 - 20,000 km) I can only say: This conversion kit is in my opinion preferable to most ready-made pedelecs - especially if you want to go a little faster than 25 km/h, but still do not want to accept the disadvantages of an S-pedelecs (helmet and insurance obligation). I don't mind the somewhat "untidy cable mess"; it should be easy to see that it's a self-built pedelec. Also the advice in the run-up was great: competent, not annoyed (even if I had questions) and always friendly (I think that Mr. Bauditz "looked after" me). Thank you very much!"

EBS BergFex PLUS conversion kit from the PRO series

 Experience with Ebike Solutions

I would like to send you feedback about the e-bike system I bought from you.

The installation was relatively problem-free and finished in about 2.5h. The following day I laid the cables and roughly adjusted the CA to fit the conditions. I didn't mount the throttle grip because I couldn't find a suitable place on the lower link. So far I haven't missed it either. The bottom bracket can do everything I need and more. At the moment I have driven almost 800 km with the new system and can use my Bionx battery as well as LiPo batteries from my model aircraft very well. Over time I have improved the settings on the CA so that it is a real pleasure to ride my bike.

I have occupied all three memory slots and set them differently. Among other things, I have a Power-Mode, which is really great and I have already reached a speed of 51 km/h. I have a very good memory capacity. It would have been even faster, but I couldn't keep up with the cadence on the crank anymore - I don't need it either, because I only ride over 25 km/h occasionally. Nevertheless, a 250 W engine would not have been the right thing for me! In contrast, I have set a memory so that you hardly notice the engine but it still does a good job. I can ride with the usual pedal pressure as if I didn't have an e-bike. If an incline or stronger headwind comes, the engine starts very gently and 'frustrates' the cycling.

The drive is so versatilely adjustable that I could configure it exactly according to my ideas and wishes. I had had very bad experiences with two pedelecs. I also don't like it when the motor starts hard even though it's not necessary. I find exactly the same with a pedelec when the engine suddenly stops at 25 km/h instead of gently adjusting the speed. With the CA I was able to remove all these bad settings. The engine support is definitely not comparable with an off-the-shelf pedelec anymore. Everything happens very gently and almost imperceptibly, but with power without end. I also tested the drive on the Königstuhl and in Kraichgau. The Kraichgautour (65 km) needed only 2.5 Ah engine support although there were steeper inclines and I had turned the potentiometer up. Normally the potentiometer is at 2-3 when I drive. Even at the Königstuhl, which I hit from Ketsch via Sandhausen and Leimen, I only needed 4 on the potentiometer. And I am definitely not a mountaineer. The engine had until now a maximum temperature of just over 60°C and that only on the inclines of the Königstuhl. Otherwise the temperature oscillates between 35°C and 45°C. At the moment I drive with model construction batteries (LiPo) 14S 5000 mAh and come with it problem-free on 60-80 km distance.

I would like to thank Mr. Dittrich once again for his advice and Mr. Lott for providing the right rim at short notice. If you have a customer who would like a 'second' opinion about your drives, you are welcome to refer him to me. I am also willing to help customers who want to install the drive themselves - as I do - with words and deeds."
