Bafang goes on the offensive against Bosch with new mid-motors and up to 800% motor assistance

At Eurobike 2025, Bafang used the opportunity to present two electric motors for bicycles, namely the M430 Cargo and M510RS. Both are mid-drive motors, which shift the center of gravity toward the middle and downwards, which is desirable in principle, but also puts a strain on the bike's drive system, i.e., the chain and gears.

The M510RS is a motor designed for e-mountain bikes. A rated continuous output of 250 watts is specified, while Bafang specifies the peak output as 790 watts. Only the rated continuous power is relevant in most countries, of which the legal limit is often 250 watts. According to Cleanrider, the maximum torque is 110 Nm. The 2,900-gram motor combines a cadence sensor with a torque sensor, providing particularly precise assistance tailored to the rider's effort. Maximum assistance is specified at 340% of your own effort.

The M430 Cargo is said to offer significantly greater assistance, which is only logical since cargo bikes also have to propel very heavy additional loads such as passengers or luggage. Up to 800% support is specified here, with a torque of up to 150 Nm – at least in the version designed for North America. The downside is the weight: At 4 kilograms, the motor is very heavy. Lastly, a new app called Bafang Go allows riders to configure Bafang's new mid-drive motor to their needs. 

Information on price and availability of the motors is still pending.
