Torque Sensing Hub Motors are Here

The company TDCM has made some innovative motors over the years. For a while we carried their IGH motor that featured a 5 speed Sturmey Archer internally geared hub inside a direct drive motor. More recently they've introduced an even more powerful motor using a quick-release axle and featuring a torque sensing freehub body

It took us a while to develop a full kit package around this motor as it needed a custom controller, a custom torque-arm, and a customized CA3 firmware. But we've pulled it all together and are now releasing the TSM-A5 kit. Watch Robbie's summary in this video.

More detailed information including specs, user manual, CAD drawings etc. are on our Kit Info Page,and they can be purchased as part of a full conversion kit from our Ready-To-Roll Store page
