$200 · Bionx bike & accessories

This is a Bionx system fitted to an old ‘80s style mountain bike, suitable for someone with electronics skills, tools and a willingness to embark on a DIY project. It’s a 500 watt, 36 volt system with torque sensitive pedal assist and regenerative braking. It comes with the battery, LCD control panel, motor mounted to a 26” rim, charger, instruction manual, head & tail lights, mounting hardware, Bionx extension cable and a sheet with some special codes to disable the speed limiter. The battery is past the end of its service life so the bike will only go about 5km on a full charge. The Bionx company no longer exists and you can’t get replacement batteries, so you either have to replace all 60 of the 18650 cells inside the battery box, or you have to modify the motor to bypass the internal motor controller and bring the 3 phase power connections out through the axle so you can use an external motor controller & off-the-shelf ebike battery. I can give you the link to a YouTube video that shows you how to do this. Also, if you’re interested in this project, I’m happy to chat with you about my findings and you can take it for a test ride if you leave me with a piece of ID. If you’re wondering if this is a worthwhile project to embark on, I’d say definitely yes if you’ve got the means. Bionx made a very high quality product and the silent, maintenance free direct drive motor combined with torque sensitive pedal assist makes for a sublime cycling experience. Asking price is firm.
