Gustavo E‑bike Chainring – Replacement Chainring for Bafang BBS01 / BBS02

The Gustavo E‑bike Chainring is a replacement chainring designed for Bafang BBS01 / BBS02 mid-drive motors. Made from lightweight aluminium alloy, it lets you tailor your e‑bike's gearing to the way you ride: climbing, carrying a load, city or road riding, depending on the tooth count you choose. It is a lighter alternative to the original chainring, with a narrow‑wide tooth profile for better chain retention – particularly useful for mountain biking, loaded e-bikes or uneven tracks.

The chainring is available in several sizes (36, 38, 40 teeth, and sometimes more depending on the version), giving you the flexibility to adjust torque and cadence to suit the terrain or your riding style.

Key features

• Compatibility: designed for Bafang BBS01 / BBS02 motors – a direct replacement for the original chainring.

• Machined aluminium construction: lighter than a standard steel chainring, which reduces rotational inertia and improves responsiveness.

• Narrow-wide design: alternating narrow and wide teeth grip the chain better and reduce the risk of chain drops, even on rough terrain.

• Choice of size: different tooth counts (36, 38, 40, etc.) allow you to adjust the gear ratio to suit your riding (climbing, speed, comfort, load).

• Suitable for standard 7- to 11-speed chains (generally compatible with this type of chainring).

• Easy installation: fits directly inside the motor housing (replacing the original chainring) with no major modifications – but check compatibility and chainline alignment.
