Our take on the Bafang 48V 750W BBS02B Can Mid-Drive Ebike Motor Kit with 48V20Ah Downtube Battery & Dispaly for BB 68-73mm Mountain Bike City Bicycle Conversion Kit

A conversion kit that turns a standard bike into a mid-drive ebike: a Bafang BBS02B 750W motor, a 48V 20Ah downtube battery and a display. The mid-drive layout drives the cranks through the bike's gears, so it climbs better than hub-motor kits of similar power. It fits frames with a 68-73mm bottom bracket, which covers most mountain and city bikes. The motor unit weighs about 14.5 lb, and the kit carries no written warranty, so buyers rely on the seller and on Bafang's reputation for durable, serviceable drives.

Questions and answers

Will this fit my bike?
It fits bikes with a 68-73mm bottom bracket shell, which covers most mountain and city frames. Measure yours before ordering; fat-bike and press-fit frames need different hardware.
How fast will it go?
A 48V 750W BBS02B typically reaches around 25-28 mph depending on gearing, rider weight and terrain. Local law may cap assisted speed lower.
How far can I ride on the 48V 20Ah battery?
Expect roughly 30-50 miles per charge, more with light pedal assist and less on throttle-heavy or hilly rides.
What is in the box?
The kit includes the BBS02B motor unit, the 48V 20Ah downtube battery, a display and the mounting hardware for the bottom bracket.
Is it hard to install?
It is a DIY job: you remove the cranks and bottom bracket, fit the motor and route the battery and display wiring. Budget a few hours and the right tools.
Does it work with my bike's gears?
Yes. The motor drives the chainrings, so it uses your existing rear gears, and it works with derailleur setups.
