We specialize in professional service and repair of electric bicycle drive systems and batteries, with a focus on hub motors, Bafang mid-drive systems, and lithium battery packs. Whether your e-bike has lost power, makes unusual noises, won’t turn on, or is showing error codes, we provide accurate diagnostics and reliable repairs to get you back on the road.

Hub Motor Service
We repair and maintain front and rear hub motors, including bearing replacement, hall sensor and wiring repairs, water damage recovery, controller troubleshooting, and full motor rebuilds. If your motor is running rough, cutting out, or not engaging, we can restore smooth, quiet operation.

Bafang Mid-Drive Repair
We service Bafang mid-drive units such as the BBS01, BBS02, HD, M400, M500, M600, and Ultra systems. Our services include internal gear and clutch repair, controller replacement, firmware troubleshooting, torque sensor calibration, noise reduction, and full drivetrain inspections to keep your system running strong and efficiently.

Battery Testing, Repair & Rebuilding
We provide complete battery diagnostics, cell balancing, BMS troubleshooting, and lithium-ion pack rebuilding. If your battery has reduced range, won’t charge, or shuts off under load, we can often repair or rebuild it for a fraction of the cost of replacement. We also offer capacity upgrades and safety checks to ensure long-term reliability.
