The geared M-series feature two mid motors, the M500 with 250W and the M600 system with 350 / 500W engines both offer peak torque values of 95-110Nm. This results in a complete program of EU compliant 25km/h and 45km/h (S-Pedelec) and 32km/h (20m/h) US versions.

Combining this with a single or double chainring (32T/44T) option will deliver multiple gearing choices for the many MTB sub-categories. Bafang states that the ultra-short RC compatibility of less than 450mm and a Q-Factor of only 177mm will make the motor perfect for nimble and uphill-ready hardtail and full suspension e-mountainbikes. The motors also offer system weights of less than 3.0 and 3.4 kg, ISIS drive BB, customization of motor covers and alloy bash guards, and potential for private labelling.

Additional integrated battery options
The M-series systems will be compatible with the new 370Wh or 600Wh F-Series InTube batteries, both for under or top downtube insert positions, as well as the semi integrated battery with 1.000Wh maximum.
All batteries currently use 18650 cells from Panasonic/Samsung. In the near future these will be offered with the new 21700 cell standard. CanBus and UART communication protocol and two different charger options with 2 and 3 A charging capacity will complement the battery offering.

Announced earlier in March this year, Bafang is progressing on an automated battery production facility in Suzhou for the assembly of the battery core packs. The strategy includes that customers in the future can also chose to develop their own final battery pack size, shape and material or cosmetic design options.
