Bafang To Unlock E-Road Trend with Mini Motor Launch at China Cycle


SUZHOU, China – The biggest news Bafang will be displaying at the China Cycle Show, which is starting on Sunday, is its new M800 mini mid-motor for e-road, e-gravel or e-cyclocross bikes. Asia’s leading maker of e-bike components claims that e-road could well be the next big trend after the e-MTB.

However, to turn e-road into that next big trend more is needed than standard-size mid motors, says Bafang. With its new M800 mini mid drive system, the right technology is now available for the e-road bike and its sub-species.

Design opportunities

On its new M800 e-road drive system Bafang says “The form factor of this new mini-size motor creates new and significant design opportunities for bike brands across the globe who are developing ‘e-road racing style’ bikes, including gravel and cyclocross concepts. Functionality is key, paired with quiet and smooth operation controlled by dual torque and speed sensors. The motor offers single and double chainring compatibility (chain wheel size 44T or 34/50T), and while it can easily be set to the EU legal limit of 25 km/h, with its maximum speed of 45 km/h, the system is also capable of use on speed pedelecs.

Total system weight below 4.4 kg

“One of the key advantages of the new drive unit is its low weight, at less than 2.3 kg, but with a 200 W rated output power and a max torque of 55 Nm. The electronics and 200 Wh inTube battery add just 2 kg more. This takes the total system weight to less than 4.4 kg, including display and remote shifters.

“The pedaling assist level can be set in five steps controlled by 1 or 2 satellite shifter pods, which can be individually placed on the drop handlebar. The 2.2 inch TFT color display offers up to 10 settings.

“Since an e-road bike will very quickly exceed the 25 km/h (EU) legal motor assist speed threshold, the drive has been tuned to perform optimally when starting off and accelerating, as well as on short sprints and steep climbs. For the US and other regions, the speed limit can be set at 32 km/h or 45 km/h instead. But whatever the exact limit, most important is that when the limit is reached, the drive train unit runs almost resistance free. Thus the rider’s own pedaling effort above the limit speed is not affected. This will typically be when riders are pedaling in the upper 20s to mid-30s km/h speed range.”

Next to the M800 e-road drive system Bafang presents more news in Shanghai like an updated and facelifted Mac Drive System. The new M420 offers new options for modern-styled city and trekking bikes.

The 2018 China Cycle Show runs from May 6 – 9 in Shanghai’s National Exhibition & Convention Center.
