Bafang has updated its mid-range mid-motor, which was formerly the M400 and is now the M410. At 3.2kg, the new version is 700g lighter than its predecessor, but is still capable of generating a claimed maximum torque of 80Nm at 120RPM.
The M410 slots in below the 95Nm M510 in Bafang’s line-up. The latter was also recently updated with a 500g weight reduction coming alongside an improvement in the overall torque curve.
The M410 hasn’t seen any such performance boost, meaning the significant weight reduction is really the headline change. The connection interface stays the same as well. (It’s the same as for the M510.)
It’s still a decently hefty motor though and you can expect to see it on used on eMTBs, trekking e-bikes and e-cargo bikes.
Eskute’s Polluno Pro and Neptuno Pro are two that we’re already aware of.
The new M410 follows the launch of the H700 dual-speed rear hub motor last year. That system, primarily intended for city e-bikes, automatically adjusts the gearbox ratio based on the speed of the bike, improving climbing efficiency relative to the Chinese firm’s other rear hub motors.
