UK Road‑Legal Disclaimer

Under UK law, electrically assisted pedal cycles (EAPCs) must have:

  • ≤ 250 W continuous motor
  • Pedal-assist only (no throttle)
  • Assistance stops at 25 kph (15.5 mph)
  • Pedal-activated assistance

The Cyrusher Rumble UK model is fully compliant with these standards. Any modifications (e.g., derestricting motor, adding throttle, increasing speed) will void its EAPC status, requiring DVLA registration, insurance, and helmet, and will make it illegal for road use.
