Tell us what's wrong. We'll build the exact parts list.
Pick what you need to fix, answer only the questions that repair needs, and send a photo for anything you can't check. Wheel size, dropout width, brakes, voltage, plugs and display are all matched to your bike before anything ships. Parts ship from U.S. stock.
Fit guaranteed — if a part we picked doesn't fit your bike, we replace or refund it. Refunds are issued once the part is back with us; return shipping is paid by you.
Send photos — we check the fit before you pay

What do you need to fix?
Pick one. We only ask what that repair needs, and every question has an “I don't know” that turns into a photo instead.

Photos
Tap the drawing in a box to see what the photo should show. Boxes marked Required are needed before we can quote.
More photos (optional)
Everything is answered. See right away which parts fit your bike — no name or email needed.
Some of your answers are “I don't know”, so we check those from your photos before you pay. Send it for a fit check below — no payment is taken until your quote is ready.
About you
Only needed when you send this for a quote or a fit check. We use it to send your quote and case link — nothing else.
No payment is taken here. We check your answers and photos before you pay, then your quote appears on your own case page.
Example drawing — your photo should show the same thing.
Controller or Display Fault?
Controller and display protocols differ between brands — a display bought on its own often will not talk to your controller, even when the plug fits. Run the step-by-step diagnosis first so you replace only the part that actually failed.
Motor or Wheel Fault?
Many dead-motor problems turn out to be a hall sensor, a phase wire or a loose connector. Test those first. If the motor itself has failed, measure your dropout width before ordering: 135mm is standard, fat-tire frames use 170mm or 190mm, and those two are not interchangeable.
Sensors & Wiring
Cadence sensors, throttles, brake levers and wiring harnesses. Before you replace a sensor, check the assist level, the brake levers and the magnet gap — around 80% of pedal-assist faults turn out not to need a new part at all.
We Check the Fit First
Send us four photos and we will confirm the part fits your bike before you order.

Not Sure Which Part You Need?
- Lights on, but the bike won't move? Work through five tests in order, brakes and throttle before the controller. Run the five tests →
- No power at all? Nothing lights up: check the battery charge, the main power connector and the fuse. What to check first →
- Pedals but no power? The fault is in the pedal-assist chain, not the motor. Five checks, four are free →
- Motor running on its own? Stop riding and remove the battery. Read this first →
- New display won't talk to your controller? Why the plug fitting is not enough →
- Motor jerks or won't spin after a swap? The phase and hall wiring guide →
- Buying a wheel or motor? Measure your dropout width first →
