Shengyi X1

The SX1 front and SX2 rear motor kits are ideal for people looking for a silent helical geared hub motor in the mid-range power level. These don't have quite the hill climbing capabilities of an eZee or GMAC motor, but they more powerful and robust than the G310/G311 hubs from Bafang and are OK with high RPM applications too. See the motor info page here. Our kits include combined speed and temperature signaling on the Z910 plug to provide full thermal rollback protection for the motor when used with a V3 Cycle Analyst.
