The Gustavo E-bike Chainring is a replacement chainring designed for Bafang BBS01 / BBS02 central motors. Made from aluminum (a light alloy), it allows you to adapt the gear ratio of your e-bike to your use: uphill, heavy use, city or road, depending on the number of teeth chosen. It's a lighter alternative to the original chainring, with a "narrow-wide" design to improve chain retention - especially useful for mountain biking, loaded bikes or uneven roads.
The chainring is available in several sizes (36, 38, 40 teeth, sometimes more depending on the version): this offers the flexibility to modulate torque and cadence according to terrain or use.
Key Features
-
Compatibility: designed for Bafang BBS01 / BBS02 motors - direct replacement for the original plate.
-
Machined aluminum material: lighter than a standard steel platter, reducing inertia and improving responsiveness.
-
Narrow-wide" design: alternating narrow and wide teeth to better "bite" the chain and reduce the risk of derailment, even on difficult terrain.
-
Choice of sizes: different tooth options (36, 38, 40, etc.) allow you to adjust the transmission ratio to suit your needs (climb, speed, comfort, load).
-
Adaptable to standard 7 to 11-speed chains (generally compatible with this type of chainring).
-
Simple installation: direct mounting in the motor housing (by replacing the original plate), without major modifications (but check compatibility and alignment).
