This video shows my latest friction drive installed on a light weight high end road bike. Assist is set deliberately low at 200W however with a total bike weight of 19.8 lb (9kg), power is more then adequate with a cruise speed of 25 mph (40kph) easy to maintain with light assist from the rider. This drive is not for the person looking for a free ride however with a bit of pedaling effort, an average rider is capable of staying with the best.
