Steel Mid-Drive Chainring
Stop shredding alloy. A steel (or hardened) chainring on a BBS/Ultra mid-drive lasts many times longer than the stock part and improves chainline.
The stock chainrings on Bafang mid-drives are soft alloy and wear quickly under motor torque. Upgrading to a steel or hardened aftermarket ring (Lekkie Bling Ring, Luna Eclipse) dramatically extends life and often corrects the chainline for quieter, smoother running.
Picking the right tooth count also tunes your bike: fewer teeth for more climbing torque, more teeth for higher top speed. It's a cheap, high-impact upgrade for any mid-drive conversion.
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
- Lower tooth count = more climbing torque; higher = more top speed.
- A corrected chainline reduces noise and drivetrain wear.
- Replace the chainring and chain together for best results.
