Why call me instead
Many bike mechanics won’t touch your battery, motor or throttle. That’s the half that usually breaks.
It leaves e-bike owners with two bad options: ship the bike back to a direct-to-consumer brand and wait weeks, or drive to a shop that only services electrical on bikes it sold. I do the whole bike — the mechanical side and the electrical side — at your house.
What I fix
Everything a shop does — plus the electrical.
Organized by the job, not by the kind of bike, so you don't have to diagnose it yourself before you can find it.
Electrical & Diagnostics
The differenceThe work many mechanics turn down. Batteries, motors, controllers, sensors, and wiring — measured and repaired, not guessed at and replaced.
Mechanical Service
Everything a bike shop does, done in your driveway — to e-bike loads, with e-bike torque specs, using parts rated for the weight and speed.
Tune-Ups & Setup
Scheduled service, new-bike builds, and whole-neighborhood service days.
Scooters, Bikes & Accessories
Servicing all brands and styles: electric scooters, regular bikes, and the surf racks, lights and accessories that go on them.
The electrical half
A dead e-bike is usually a $45 connector, not a $700 battery.
The most expensive mistake in e-bike ownership is replacing a battery to fix something that was never the battery. It happens because the only people willing to open the electrical system are often the brand’s own service center — and their answer is usually a new part.
I measure instead. Charger output under load, pack voltage and cell-group balance, controller supply and phase continuity, hall sensor signal, PAS and torque sensor output, brake cut-off state, and the stored error log. Every step gives a number, and the number tells you which part is actually bad.
Near the coast, salt air corrodes connectors and charge ports — and when that’s the fault, the fix is a clean, a crimp and a reseal, not a battery.

15 free tools built from the makers' own manuals and California law — every number sourced, the arithmetic shown. No sign-up.
How it works
Four steps. No loading a 65-pound bike into a car.
The whole point of mobile service is that the hard part — moving the bike — stops being your problem.
- 01
Text me a photo
A picture of the bike, your ZIP code, and what it's doing. That's usually enough for me to know what I'm walking into and what it'll cost — before I drive anywhere.
- 02
You get a real quote
A number, not a range, for anything I can price sight-unseen. If it genuinely needs diagnosis first, I tell you that and the diagnostic is $99 — waived if you have me do the repair.
- 03
I come to you
Home, office, the trailhead, wherever the bike is. The van carries its own power, air, light and water — all I need is a flat parking-space-sized spot. I text before I arrive.
- 04
We test ride it together
I don't hand back a bike I haven't ridden. You get a walkthrough of what changed, what I found, and what's coming next — plus 90 days on the labor.
Pricing
The trip fee is the number nobody publishes. Here's mine.
Most mobile e-bike services in Orange County charge $95 to $125 just to show up, and almost none of them say so on the website. Zone 1 is free, and Zone 2 and 3 are credited back.

Is your e-bike battery legal in California?
Since January 1, 2026, an e-bike can’t be sold or leased in California unless its battery has been lab-tested to a standard referenced in UL 2849 or EN 15194 and labeled. Replacement packs and chargers are covered too. I check the certification label on every visit, free.

Portrait of David — in front of the van, holding a tool, looking at camera. This is the second-most-important photo on the site after the hero.
Who shows up
You get David Palacios. Every time.
No dispatcher, no rotating technician, no call center. When you text this number, I’m the one who answers it, quotes it, drives out, does the work, and comes back if something isn’t right.
That’s the whole reason I run it this way. A bike shop can’t afford to spend forty minutes tracing a wiring harness to find a corroded pin — it has to move bikes through the stand. I can, because I’m at your house and the bike isn’t going anywhere until it works.
Brands & systems
Every brand. Especially the ones with no local dealer.
Direct-to-consumer e-bikes are the best bikes on the market for the money and the worst to get serviced — there's no dealer to walk into. A mobile technician who does electrical work fills that gap.

FAQ
Questions people ask before they call
If it's not here, ask me directly — I'd rather answer it than have you guess.
Do you actually work on batteries, motors, and controllers — or just the mechanical stuff?
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.
What does it cost just to have you come out?
Nothing in San Clemente, Dana Point, Capistrano Beach, Monarch Beach, or San Juan Capistrano — that's Zone 1 and there's no trip fee at all. Zone 2 (Ladera Ranch, Rancho Mission Viejo, Laguna Niguel, Mission Viejo, Aliso Viejo, Laguna Beach) is $35 and Zone 3 is $65, and in both cases the trip fee is credited in full toward any service over $150. For comparison, most mobile e-bike services in Orange County charge $95 to $125 just to show up.
How fast can you get to me?
Most jobs get scheduled within two to four days, and I hold same-day and next-day slots for bikes that are genuinely unrideable — no brakes, no power, or a battery showing warning signs. Text a photo of the bike with your ZIP code and what's happening and you'll hear back within 30 minutes during business hours (Monday through Friday 8am–6pm, Saturday 8am–4pm).
What brands do you work on?
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.
My range dropped a lot. Do I need a new battery?
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.
Do you show your prices?
The full price list is published on the pricing page — every service, with real numbers, including the trip fee and the hourly rate for custom work. Tune-ups are $129 Essential, $209 Complete, and $429 Overhaul, with a $99-per-bike rate at three or more bikes in one visit. Diagnostics are $99 for the e-system and $59 for the battery, both waived if I do the repair. Parts are billed at cost plus 15% and quoted before anything is ordered.
Is there a warranty on the work?
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.
What can't you do at my house?
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.
How often should an e-bike be serviced?
Twice a year for anyone riding weekly, and that's a real recommendation rather than a sales pitch — an e-bike is heavier than a regular bike, holds higher speeds, and puts motor torque through the chain, so brake pads, chains and tires wear faster. In coastal South Orange County there's a second reason: salt air corrodes charge ports, battery contacts, and connectors within a couple of years, and catching that early is a $45 clean-and-reseal instead of a $700 battery.
