Working on your BAFANG BBSHD G320 mid-drive e-bike conversion or repair? If the motor shaft is worn or damaged, this precision-made 5-way transmission axle is exactly what you need. It's a direct OEM replacement, so it should drop right in and get your motor running smoothly again. The key is picking the right length for your bike's bottom bracket shell. We offer it in three super common sizes: 120mm, 100mm, and 68mm. Make sure you measure your old one or know your frame specs before choosing. It's machined from high-grade steel to handle the torque and power transfer of the BBSHD system, and built to precise tolerances for a perfect fit. Whether you're a DIY enthusiast fixing up your ride or a shop with a customer in need, this is the essential part to get that powerful mid-drive motor back on the road. Just match the length, install, and you're good to go.
