Looking for recommendations in converting an older MTB Tandem to an E-Tandem. Would like to do a rear wheel conversion. Do I just buy one of the many kits on eBay or would there be a specific brand or vendor to use?
The GMAC motor is Grin’s customization of the powerful rear MAC motor, modified to run without a clutch for regenerative braking, a huge plus for cargo hauling applications. A round axle and integrated torque arm allow for powerful regen without risk of axle spinout.
The GMAC is a good option for that application and backed by the best hub guys and gals in the industry, not cheap but not cheaply made.
Get all but the battery from them and get a suitable ah battery with good cells, 48v/17ah shark types work well.
