Electric Scooter Repair

Yes — stand-up electric scooters from Segway-Ninebot, NIU, Gotrax, Hiboy, Apollo, Xiaomi and other brands. A flat on a tube-type scooter tire is $69 per wheel with the tube included, a scooter tune-up is $79, and brakes, folding stems, throttles, controllers and displays are all repaired at your home. The $99 e-system diagnostic is waived if I do the repair.

Yes. California Vehicle Code §21235 requires a valid driver's license or instruction permit to operate a motorized scooter. The same section bans passengers, bans sidewalk riding except to enter or leave a property, and requires riders under 18 to wear a bicycle helmet; §22411 limits motorized scooters to 15 mph. E-bikes are treated differently: under §24016 an e-bike rider needs no driver's license, registration or plates.

All of it. This is the main reason to call me instead of a general mobile bike mechanic. Most mobile bike services in Orange County explicitly decline battery, motor, throttle, and controller work, which means a bike with an electrical fault has nowhere local to go. I diagnose and repair charge ports, battery management systems, controllers, displays, throttles, cadence and torque sensors, brake cut-off switches, wiring harnesses, and hub and mid-drive motors — plus everything mechanical.

Every brand. That includes direct-to-consumer bikes with no local dealer — Rad Power, Aventon, Lectric, Ride1Up, Velotric, Heybike, Himiway, Juiced, Super73, Segway — and dealer brands like Specialized Turbo, Trek, Giant, Cannondale, Electra, Gazelle, Tern, Pedego, Blix, Magnum, and Riese & Müller. On the motor side I work on Bosch, Shimano STEPS, Brose, Yamaha, Bafang, Fazua, Mahle, and generic hub systems. One honest caveat: Bosch and some Shimano systems lock firmware and certain diagnostics to authorized dealers. I can do every mechanical and electrical repair on those bikes and I'll tell you upfront on the rare occasion something has to go through a dealer.

Probably not, and this is the most expensive assumption in e-bike ownership. Lost range has at least five common causes and only one of them is a worn battery: low tire pressure, a dragging brake rotor, a worn or dry chain, colder weather, corroded battery mount contacts, and actual capacity fade all produce the identical symptom. A $59 battery health test measures capacity against the pack's rated watt-hours and checks balance across cell groups, which tells you definitively which it is. That fee is waived if you have me do the repair. A new pack is $400 to $1,200 — it's worth $59 to find out whether you need one.

90 days on all labor. If something I worked on isn't right afterward, I come back and fix it — no trip fee, no argument, in any zone. Parts carry whatever warranty the manufacturer provides and I'll handle the claim paperwork with the brand for you.

Three things go to the bench rather than the driveway: cell-level battery pack repair (opening a lithium pack in a customer's garage isn't something a careful technician does), full wheel rebuilds and rim replacement, and internal motor rebuilds that need a press. For all three I pick the part or the bike up and bring it back, usually within two to four days. Everything else — including motor removal and reinstall, controller and display replacement, harness repair, brake bleeds, and full tune-ups — happens where your bike is.

No. The van carries its own power, lighting, compressed air, and water. All I need is a flat spot roughly the size of a parking space, within reason of where the bike is. Driveway, street, garage, courtyard, parking lot, or a turnout on a Laguna hillside all work fine.
