Once a Lithium-Ion battery is included, this is most probably the best value for money conversion kit you can find on the market.
The kit is a front motor-wheel design, making it incredibly simple to install. It usually takes less than an hour to complete the installation. But if you are not the DIY type, you can always seek assistance of a bike service shop. A full installation guide is included.
These kits are Pedal Assist only. Keep those cranks turning, and the motor will do the rest! Throttle options no longer available in-line with UK law.
