Hi. I converted a hybrid using the Cyclotricity eKit 700c just over a year ago. For a year it was fantastic fun and all worked very well. It was not being used as a commuter, but just for leisure on random weekends. Usually on rides between 20 and 30 miles on varied terrain, nothing too hilly. However, 2 weeks out of warranty the motor packed up. On returning the bike to shop in Surrey I was told it would cost £150 pounds to replace front wheel and motor. After spending over £700 pounds to get my bike upgraded and enjoying only a year of infrequent riding I am bitterly disappointed.
No longer a fan of Cyclotricity.
