I have a 350w Tongsheng TSDZ2 mid-drive torque-sensing motor for sale, complete with LCD display, handlebar repeater switch, all mounting brackets, and matched 12 Ah Hailong downtube battery with charger, integrated controller and 2 keys. It was my lockdown project. Everything works as it should. Only thing missing is the speed sensor. If fitted, this would give average speed, distance covered on display. It would also cut the motor at the legal limit of 15 mph on-road. I decided not to install it. Without the speed sensor, display still shows assist level, battery level and background light. Kit was fitted to my Specialized Rockhopper Pro (see photos), and worked very well on canal towpaths and the occasional bike trail. However, the bike needs general upgrading (forks, disc brakes), so I've removed the kit in readiness for a new chassis. I'm in Stockport. £400 ono for the complete conversion kit, including battery. Sold as seen.
