Rear Cassette Hub Motor with Helical Gears, Standard (~7.6 rpm/V) Winding. Includes 9 Pin Z910 Cable with Combined Speed + Thermistor Signal.

Availability: In stock

The Shengyi DGWX2 rear motor is a mid-sized, cassette freehub compatible 3.2kg hub with a nominal 250-500 watt power rating that works great for stealthy systems that do not require significant assist for steep hills or cargo. This motor is a bit more powerful and robust than the Bafang G310 hub and also uses silent helical gears.

This is a standard speed (8T, 7.6 rpm/V) winding that is typically used with 26" to 700c wheels. This Grin model was customized to use a combined speed and thermistor signal system allowing both speed sensing and thermal rollback from one wire of the Z910 plug. This feature is compatible with 2020 model Baserunner_Z9 controllers using a CA3-WP display.
