36V 500W Geared Ebike Conversion Kit vs BAFANG BBS02B 750W Mid Drive Kit

Buy the Bafang BBS02B if you want real climbing torque and a balanced bike, and you are comfortable with tools and a chainring swap. Buy the 36V geared hub kit if you want the simplest install, a quiet ride and a lower, more forgiving power level. The hub kit is the easier first conversion; the Bafang is the stronger, more capable drive. Owners of the Bafang praise the torque and pedal-assist feel but note the install takes patience and the chainline needs attention. The hub kit's ratings are higher, though from a much smaller sample.

• Choose the 36V geared hub kit if you want a bolt-on front or rear wheel swap that fits 20", 26" and 700C frames with minimal drivetrain work.
• Choose the Bafang BBS02B if you ride hills or carry loads and want 750W through the bike's gears with 9 assist levels.
