UK Road‑Legal Disclaimer

This e‑bike is fully compliant with UK Electrically Assisted Pedal Cycle (EAPC) regulations:

• 250 W maximum continuous motor output
• Pedal‑assist only, no throttle engaged
• Assistance cuts out above 15.5 mph (25 km/h)

Any modifications—such as removing the speed limiter, enabling throttle control, or exceeding legal wattage—would render the bike non‑compliant. In that case, DVLA registration, tax, insurance, and a valid driving licence would be required, as it would then be considered a motor vehicle. Cyrusher does not support or condone such modifications.
