This is a Merida speeder bicycle that has been converted with a simple conversion kit. The bicycle is a flat-bar road bike that is extremely common for commuters that want a balance of speed and comfort. The bicycles retail for roughly $700 to $1000 depending on choice of gears and brakes and are ideal for people wanting a fast bike suitable for conversion.
Here, we have installed a rear hub motor and a cylindrical lithium ion battery. The system can be run with a throttle only, a pedal assist only system or a combination of both throttle and pedal assist function. This is the KD51C display, it is a neat display that allows you to have up to 9 levels of pedal assist power.
If you have your own flat-bar road bike, or similar, then it is well worth considering installing a conversion kit on it. It allows fast and comfortable electric bike commuting and can be fully customised to your riding desires.
