This photo turned up on our UK forum today. This motor is now being fitted to ready-made electric bikes that cost from about £700. It's rated at 250w and anecdotally stronger than a Bosch mid-drive. Looking at the photo, it might be possible to fit it to any bike. It's made by a Chinese company called TCM. I searched, but couldn't find anything about it. Can anybody add to this?
