If purchasing this motor built into a wheel, please allow 3-4 days extra processing time to ready the wheel build. All of our wheels are hand built to order.

This motor works well as a replacement/upgrade in the ELF solar e-bike. It fits in ELFs that originally had the geared MAC motor (model years 2013-2015). If your ELF originally had the TDCM direct drive motor (made in ~2015-2019), we recommend this motor instead. 

Pair with the Baserunner L10 or Phaserunner motor controller for optimal results.

"GMAC Clutchless Geared Hub Motor, Standard 10T (8.1 RPM/V) winding. This motor includes an internal 6-pole speedeometer sensor so it can use a CA-DP device and not require an external speedo pickup. Includes 3 piece CNC'd torque arm with inner spline made from 7075 alloy. For more details see the GMAC Info Page
