Mid-Drive Electric Bikes: The Bafang Crank-Drive Range

Seventeen models in the catalogue drive through the cranks. This page maps the mid-drive lineup — M620, M600, M400, BBS02/BBS-HD and the TrunkRun units — across the fat, mountain, city and folding families.

A mid-drive motor applies power at the cranks, so it multiplies torque through the bike's gears: the same 500W produces far more climbing pull in a low gear than a hub motor of equal rating. This factory's catalogue is unusually deep in mid-drives because the company started as a mid-drive motor maker (2011–2014, inner-rotor motors exported to the Netherlands and Japan) before it built complete bikes.

The mid-drive city models (C7M, C9M, C8M) are the commuter expression of the same idea — torque for hills and loads in a 25 km/h city format — while the S2 cruiser's specification table also lists an M600 mid-drive. The mid-drive folding F7 shows the breadth of the platform: even the smallest family has a crank-drive option.

Mid-Drive or Hub?

Mid-drives cost more and wear chains faster; hub motors are simpler and dominate the value lines. The decision framework, with these models as examples, is in the mid-drive vs hub motor guide, and motor-only sourcing is covered on the electric bike motors page.

Questions Buyers Ask

Can I order samples first?

Yes — under the factory's published sample policy, spare units can be provided for sampling; the sample fee and courier cost are paid by the buyer. Confirm availability for the models you want when you inquire.

Which mid-drive is the strongest in the range?

The M620 builds (E18-A, B11, M3 (M620)) and the B17's Ultra are the 1000W top of the range; the E18-A's published peak torque claim is 200 N.m. Confirm the current motor build sheet for contractual figures.

How long does production take?

The published lead time is 30–60 days after the advance payment is received, depending on the product category and order quantity. Ask us to confirm the schedule for the exact models in your inquiry.

What certificates do the products carry?

Certificates available upon request. Send your target market in the inquiry and we will confirm which documentation can be provided for the models you are sourcing.
