Bafang Ebike Conversion Kits
Most complete bikes in this catalogue run Bafang drive systems, and Bafang-standardized kit programs are specified against the same landscape: the BBS02/BBS-HD crank drives and G-series hubs that run through the production range.
Standardizing a conversion program on one motor ecosystem simplifies everything downstream — dealer training, spares, diagnostics and warranty handling. In this factory's production range, Bafang is that ecosystem: the M620, M600 and M400 mid-drives, the BBS02 and BBS-HD crank drives, and the G010, G020, G060, G062 and H700 hub motors appear across the fat, mountain, city and folding families. That landscape is the starting point when a Bafang kit program is specified; the exact systems in a program are confirmed in its build sheet.
Bafang Systems in the Production Range
| System | Type | Used In Production | Production Role |
|---|---|---|---|
| BBS02 (48V 750W) | Mid-drive (crank) | B15, B19, B8 M fat bikes | The high-torque crank drive of the production fat range |
| BBS-HD (48V 1000W) | Mid-drive (crank) | B13 fat mountain bike | The heavy-duty crank drive in production |
| G-series rear hubs (250–750W) | Rear hub | C1 (G010), B17-C (G020), B10 (G060), B8-U (G062), EC2 (H700) | Hub systems from city 250W to fat-bike 750W |
| M400 (36V 250W) | Mid-drive (crank) | F7 Mid-Drive folder; M9 runs the MAX version | The light mid-drive of the folding and trail lines |
The flagship M620 and M600 mid-drives are integrated-frame systems in production (the frame is built around the motor), so a conversion program normally starts from the BBS-series crank drives, which are designed for standard bottom-bracket shells. If your host frames are being manufactured for the program, integrated M-series configurations can be discussed as part of a complete-bike or frame program instead — see electric bike frames.
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 Bafang kit suits a fat bike host?
Send the host's wheel size, tire width and dropout or bottom-bracket details first. The production fat range shows the landscape by complete-bike example — BBS02 in 750W builds, BBS-HD in the 1000W B13, G-series hubs in hub builds — but which system a kit program can be supplied with is confirmed in writing in the build sheet.
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.
The commercial argument for standardizing on one ecosystem is the service tail. When a retailer's conversions and their complete-bike sales speak the same component language, diagnostic knowledge, firmware familiarity and parts stock carry across both. In this factory's production range that ecosystem is Bafang — the M-series mid-drives and G-series hubs — which is why Bafang-standardized kit programs start the conversation here. A rider whose converted bike and whose spouse's factory bike share a display language and a battery format is a rider who comes back to the same shop. For kit retailers, that ecosystem discipline is worth more than a marginal saving on a no-name drive unit with no parts behind it.
