The Shengyi DGWX1 front motor is a compact, disc compatible 2.95kg 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 G311 hub and also uses silent helical gears.

This is a fast speed (6T, 9.8 rpm/V) winding that is typically used with 16" and 20" 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.
