5 Key Facts About the BAFANG TUBE Battery

Frequently Asked Questions About the BAFANG TUBE Battery

How is the BAFANG TUBE battery attached to the frame?

The TUBE battery uses the frame’s standard bottle cage mounting points (two M5 bolts) or a dedicated bracket. It fits within the main frame triangle and is secured firmly before the power cable is routed to the motor. Frame triangle dimensions must be sufficient to accommodate the battery’s length and diameter.

Is the TUBE battery more discreet than the RACK battery?

Yes. Positioned inside the frame triangle rather than above the rear wheel, the TUBE battery is far less visible from most angles and does not alter the rear profile of the bike. However, it does require a frame with a large enough triangle to house it, which rules it out for some compact or full-suspension frames.

What range can I expect from a BAFANG TUBE battery?

Range depends on capacity and conditions. A 36V 13Ah TUBE battery typically offers between 50 and 90 km on moderate assist. Larger capacity options extend this range. Because TUBE batteries are physically limited by the frame triangle size, capacity is often slightly lower than equivalent RACK batteries.

Does the TUBE battery need to be removed for charging?

Most TUBE batteries can be charged either on the bike (via an accessible charging port) or removed for indoor charging. The charging port is usually located at the end of the battery case. Removal for secure indoor charging is straightforward using the mounting bracket’s release mechanism.

Also explore the RACK battery for higher capacity, the INTUBE battery for full integration, and pair with the BBS01 36V motor.
