The E-Bikes
No One Else Will Fix

Low-cost repair for Chinese and off-brand e-bikes that dealers and manufacturers won't service — and retrofits that turn the bike you already own into the e-bike you want.

“We don't work on those” ends here.

If your e-bike came from a website instead of a dealership, you've probably heard it: the local shop won't touch it, and the manufacturer is an unanswered support ticket away. I specialize in exactly those bikes. Honest estimates before any work starts, and repairs priced so fixing the bike actually beats replacing it.

  • Diagnostics error codes, dead displays, no-power mysteries
  • Motors hub and mid-drive — noise, cutouts, replacements
  • Controllers & wiring swaps, repairs, and cleaned-up harnesses
  • Batteries & charging testing, connectors, chargers, BMS issues
  • Throttles, displays & sensors PAS, brake cutoffs, replacements
  • The bike part of the e-bike brakes, drivetrain, and tune-ups too

Shop-bench photos, not glamour shots. Every repair starts with a diagnosis and an honest call — fix it, upgrade it, or don't put money into it.

Electrify the Bike You Already Love

Conversions, kits, and upgrades.

A well-fitted conversion kit on a bike you already trust often beats a new budget e-bike — better frame, better fit, and you know its history. I'll help you pick the right kit for how you ride, install it cleanly, and dial it in.

  • Full conversions turn the bike you already love into an e-bike
  • Hub-motor & mid-drive kits help choosing one, or installing one you bought
  • Upgrades bigger battery, better display, stronger brakes
  • Rescue jobs half-finished conversions and abandoned projects welcome

Can't Haul It? I'll Come to You.

Pickup available — options walked through at your door.

E-bikes are heavy, and most don't fit in a trunk. For a small fee, I'll come to you, pick up the bike, and walk through your options in person — what's likely wrong, what it should cost, and whether it's worth putting money into — before any work begins. Prefer to bring it by? Drop-offs at my Cincinnati workshop work too, by appointment.

A few details and I'll get back to you with next steps — usually a couple of questions, then an appointment to drop the bike off.
