        A bottom bracket square tapered sealed bearing on an ebike connects the crankset (chainset) to the ebike. It allows the crankset to rotate freely. It contains a spindle to which the crankset attaches while the bearing allows the spindle and cranks to rotate. The chainrings and pedals attach to the cranks.

        Bottom bracket bearings fit inside the bottom bracket shell, which connects the seat tube, down tube, and chainstays as part of the ebike frame. A square taper interface consists of a spindle with square tapered ends that fit into square tapered holes in each crank. It is super smooth with minimal friction when moving off. No cracking, squeaking, or rubbing sound during pedaling.

        This is an essential moving mechanism that is mandatory to the Land Transport Authority (LTA) requirements for an ebike to be a Power Assisted Bicycle (PAB).

        Able to fit Saso, Old Rifle, SUV, XiaoDao, Katana, TDR, Tornado, Katana, SR2, Diwang, W2C, KRD, Zebra, Eco Drive and Kudu.
