Conversion Advisor

Bicycle electric motor - Two electric bicycles with conversion kit

Conversion - Can I do it by Myself?

You can change an inner tube? Excellent! Then you also know how to retrofit your bike with an electric motor. The conversion instructions, included in every conversion kit, will support you doing so. The required tools are available from us - even on a rental basis. Should there be any trouble, we will provide advice and support.

And the best thing is: Almost every bike can be converted into an electric bike.

Conversion from Bike to Pedelec

The following video shows how N. Hilz converted his bike for his senior class high school project. According to him, the conversion was really easy and cycling with a motor is real fun. What you can see here is an conversion kit consisting of various components the battery is custom-made.

E-Bike Creation History

In the e-bike creation story we start at the very beginning. Our mechanic Matthias builds a complete Donwhill E-Bike out of the DMR frame. For a better weight shift the battery is in the backpack.

Was Does Conversion Mean?

Conversion means to turn your conventional bike into an electric bicycle. Therefore we only need a few components:

Electric Engine for Bicycles

The electric engine for bicycles transfers power to the road. For the conversion we will either use a hub motor located in the hub - the centre of the wheel or a mid-mounted motor which will be installed in the bottom bracket. You install the motor by replacing front or rear wheel by a wheel with motor or by replacing your bottom bracket by a bottom bracket with motor.

Battery

The Battery will supply power to the motor. The more energy is stored inside the battery the longer you can ride.
Electric Bicycle Motor

Controller

The Controller determines how much energy is transferred from the battery to the motor thereby controlling the motor\'s speed.

Using the controls you activate and regulate the motor. The cadence sensor detects your pedalling motion and activates the motor. Using a power throttle you ride like on a motor bike. You can use either the cadence sensor or the power throttle - or even both.

Electric Bicycle Controller

Display

With the control elements you control the electric motor for your bicycle. The pedal sensor detects when you pedal and releases the motor. With the throttle grip you ride like with a motorcycle. You can use either the pedal sensor or the throttle grip - or both.

Three Reasons why Conversion is Worth it

Conversion is Sustainable

You will keep using your existing bike instead of "retiring" it in the garage. Technology-wise and environmentally, this is the best alternative for a high-quality bike.

Conversion is Personal

WYou want something light, small, unobtrusive or extra fast and a great range? You have a special-purpose bike or your beloved bike? With us you find solutions for any type of bike and any demand.

Conversion Saves Money

You want an electric bike that is the same quality as your existing bike? When buying a new bike you have to pay the price for the bike plus the price for the electronics. If the price is less you should be suspicious. Because there might be something wrong with quality. Buying a conversion kit saves you the money for a complete bike.

Is my Bike Suitable for Conversion Into an E-Bike or Pedelec?

Convert bike to Ebike pedelec

Basically all types of bike are suited for conversion. With the help of this chart you can see, if your bike can be converted. In case you are still unsure, send us a picture of your bike in a file not larger than 10MB to the following email address: info@ebike-solutions.com. After inspection will will notify you, if a conversion is possible.
