Update on The Panther
Building a 28-mph road-legal e-bike isn’t easy. After 8 months of wiring, failures and DVSA guidance, the Panther is finally ready for inspection — and safe.
Built for the road. Designed to pass inspection. From back garden to DVSA — this is Warrior Cycles' flagship conversion.
1500W of torque, street legal, and road-tested for DVSA approval. This bike started as a converted rust bucket. Now it’s got 4-inch tyres, hydraulic brakes, a VESC controller — and a 28mph cap that keeps it Class L1e compliant.

Labels, lights, mirrors, reflectors, a side stand, number plate mount — everything has been fitted to meet MSVA standards.
