Bafang BBSHD 1000W Mid-Drive Kit
The legendary do-anything mid-drive. 1000W, 160 Nm, and a bottomless aftermarket make the BBSHD the conversion motor every builder eventually lands on.
The BBSHD is the heavy hitter of DIY e-bike conversions. It bolts to a standard 68–73mm bottom bracket and drives the chain, so it climbs like nothing a hub motor can match — gear down and it will crawl up a 20% grade fully loaded. The steel gears (versus the BBS02's nylon) are why it survives years of abuse.
It is overkill for a flat commute and it eats chains and cassettes if you mash the throttle under load, but for cargo haulers, off-road builds, and anyone who wants one motor that never feels short on power, the BBSHD is the default answer. Pair it with a quality programming cable and you can tune amps, speed limits, and PAS feel to taste.
Where to buy
Two paths — match your spend to the build. Quality picks last longer and come with real support; affordable picks get you rolling for less. Always confirm fitment, voltage, and connectors for your bike first.

Pro tips from our test team
- Run a steel chainring and a quality chain — the BBSHD will shred cheap drivetrains.
- Shift with the motor off the power; mid-drives put all torque through your gears.
- Buy the programming cable up front so you can tame the low-end and protect your drivetrain.
