The use of a stabilizer bar is strongly recommended on all BBS02 and BBSHD builds. Stabilizer Bars replace the stock fixing plate and prevent damage to your frame while keeping your motor held firmly in place. The stock fixing plate is designed to "bite" into your bottom bracket shell which permanently damages the frame. Over time the motor can become loose and eventually fail to hold its position as the bottom bracket become increasingly chewed up by the fixing plate. Using a stabilizer bar fixes this problem.
California Ebike is the original designer and manufacturer of Stabilizer Bars for Bafang Middrive motors; accept no imitation! All California Ebike stabilizer bars come laser engraved with our logo so you can be assured of the highest quality.
Original Stabilizer Bar (BSB-1)
Made of high strength 304 stainless steel, and having a mounting angle of 40 degrees, this bar will fit most non full suspension bikes and attach to the chain stay. You may also flip the bar over and attach to the seat tube to get more ground clearance. Some bending or forming may be required for a rock solid installation with either a hose clamp or suitable M6 bolt.
Heavy Duty Stabilizer Bar (BSBHD-1)
The Heavy Duty Stabilizer Bar BSBHD-1 is our heavy duty version Bafang stabilizer bar! 50% thicker than the standard model (BSB-1) and designed to handle the extra torque of the Bafang HD motors. Like the Original Stabilize bar, you can attach this bar to the chainstays or flip it over and attach to the seat tube for more ground clearance. Some bending or forming may be required for a rock solid installation with either a hose clamp or suitable M6 bolt.
Full Suspension Stabilizer Bar (BSBF-1)
The Bafang BSBF-1 Stabilizer Bar is designed to stabilize the motor on bikes with rear suspension, but can be used on almost any bike. Made of high strength 304 stainless steel, this bar attaches to the underside of the down tube. Some bending or forming may be required for a rock solid installation with either a hose clamp or suitable M6 bolt.
Note: The Full Suspension stabilizer bar is only compatible with 68/73mm bottom brackets.
