If you are an ordinary reader, you must be able to figure out how to convert a bicycle into an electric motor. But you may have more important things to do, so skarper, a start-up company, wants to help you develop a conversion kit. Colleagues of [automatic evolution] have carefully studied its working principle. Interestingly, it transfers power from the motor to the wheels through a disc that replaces the bicycle disc brake. You can see the company’s promotional video on this product below.
Unlike some modifications, with this kit, you can easily buckle the assembly to the bicycle when you need power and remove it when you need to work normally or when you want to bring electronic components into the vehicle.
The company claims that the 250 Watt electric motor can propel the bicycle to a speed of nearly 20 miles per hour. But we’ll bet that you can’t run that fast to 37 miles. On the other hand, a 30 minute charge will allow you to run 12 more miles, and a full charge will only take 2.5 hours. The battery and motor weigh slightly more than 7 pounds. Obviously, you need a bicycle with disc brakes.
The cost is about $1200, so this is not an impulse purchase. Especially if you have the time and money to launch your own solutions. For example, try sled motor. It will be easier if you have a 3D printer.
