How it works

Four steps, no surprises on the invoice

01

35-point diagnostic

We inspect electrical connectors, battery cell health, controller error logs and every torque spec on the frame.

02

Upfront price approval

No surprise costs. We text or call with an itemised estimate and wait for your go-ahead before starting work.

03

Precision overhaul

Master mechanics fit OEM components, calibrate belt tension and bring the motor firmware up to current.

04

Road test & pickup

Every bike takes a live hill-climb road test before it leaves, backed by our one-year workmanship warranty.

Showroom

Buying rather than fixing? The floor is certified too.

Every pre-owned e-bike we sell goes through the same 35-point audit and battery health readout as the bikes that come in for service.
