E-Bike Repair
that starts with evidence.
Electrical diagnostics and practical mechanical service for many hub-drive, throttle-equipped, and direct-to-consumer e-bikes.
Independent diagnostics-first service
Find the fault before replacing parts.
An e-bike problem can involve power, controls, wiring, sensors, brakes, drivetrain, or several systems at once. Sprocket Science follows the symptoms, tests what is accessible, and explains the evidence before recommending a repair.

Clear boundaries
Many machines welcome. No blanket promises.
- KT-style systems and Bafang conversions are assessed case by case; exact wiring, configuration, documentation, parts, and tooling must support the work.
- Bosch, Giant, Shimano, and other proprietary systems may require manufacturer or dealer software that is not currently available here.
- Lithium battery packs are not opened, rebuilt, modified, spot-welded, or repaired.
- Unsafe, structurally compromised, heavily modified, undocumented, or unsupported machines may be declined after review.
