Calling all e-bike enthusiasts and DIY mechanics! If you're upgrading or repairing your mid-drive motor setup, this Rockible crank arm set is exactly what you need. Made from high-quality steel, these 8.07-inch straight crank arms are built to handle the torque and stress of electric bike conversions without bending or breaking.
Compatibility is key here – these are perfect replacements for BBS01 and BBS02 drive units, so no more hunting for hard-to-find parts. Installation is a breeze; just remember the left pedal is reverse-threaded (tighten counterclockwise), while the right side is normal (clockwise). No offset design means they fit just like the originals, giving you a smooth, reliable pedal stroke.
Whether you're building a new e-bike from scratch or just replacing worn-out cranks, this set saves you time and hassle. Durable, easy to install, and made to last – it's a no-brainer for anyone serious about their ride. Stop struggling with mismatched or low-quality cranks and get your bike rolling smoothly again!
