Electric Hybrid Bikes come in a range of shapes, sizes and speicifications. Entry level bikes have motors contained in a wheel (usually the rear wheel). The next level have motor's contained in the crank area of the bike. These tend to give more even acceleration and the motor tends to have a much longer life. Bosch and Shimano Steps would be the two most well known crank drive motors, and our workshop is fully trained to service these. We have Cytech certification in the workshop on E-Bikes in general of course.
