I'm on a SCOTT Axis eRIDE EVO.

the power connector broke on my motor.

Ah yes, the power connector. The Achilles heel of more eMTB motors than manufacturers would care to admit. The short version: which motor are we talking about? Because the fix ranges from "twenty minutes and a soldering iron" to "sorry, new motor."

The usual suspects

• Bosch (Gen 4 CX and earlier) — the power cable connector at the motor end is a known weak point. @JayOwen1982 had exactly this on a Kenevo, where the connector corroded and snapped on disconnection. Bosch's Mk3 cable upgrade addressed some of it. Repairable if you're handy — unclip the contact from the white connector and slide sealing heat shrink over the existing crimp.

• Shimano EP801 — @digitale documented mid-ride shutoffs traced to the power cable connector, fixable by reseating the battery-to-motor connection. If yours is physically broken, Shimano dealers generally won't repair the connector — they replace the motor.

• Yamaha (Giant SyncDrive) — @andyb2 had a broken connector on the controller cable causing power cutouts. Giant's official line is motor replacement, but the connector itself can sometimes be re-pinned by a competent auto-electrician.

• Specialized 2.1/2.2 — Spesh's policy is famously "whole motor only," even for a £2 connector. Frustrating but consistent.

• Brose/Bulls/Levo Gen 2 — similar story. Sealed unit mentality.

What to actually do

1. Photograph it before you touch anything. If it's under warranty, the dealer needs to see the original failure mode, not your repair attempt.

2. Check warranty status — most eMTB motors carry 2 years. Some brands (Bosch via dealer) have extended goodwill on known connector issues.

3. If out of warranty and you're competent with a soldering iron: the contacts inside the white Bosch-style plug can be released with a small pick, re-crimped or soldered, and sealed with adhesive heat shrink. Riders on here have done this successfully for years.

4. If you're not confident — Innotrace (UK) and a handful of independent specialists will repair connectors rather than swap whole motors. Worth a phone call before accepting a £900 motor quote from a main dealer.

One thing to rule out first: is it definitely the connector that's broken, or is the cable itself damaged further up? A 0.8mm internal cable break (as @ozzybmx found) looks identical from the outside but needs full motor removal.

What bike and motor is it, and is it inside warranty? I can get more specific from there.
