500 W E-Bikes in the UK: Are They About to Become Legal?
500 W E-Bikes in the UK: Are They About to Become Legal?
🚦 Current Law
- Max 250 W continuous motor output.
- Motor assistance must cut at 15.5 mph / 25 km h.
- No throttle-only running above 4 mph.
🗓️ How We Got Here
Feb 2024 – Jan 2025 timeline
- Feb 2024: Department for Transport opens a “Smarter Regulation” consultation suggesting a 500 W limit and legal throttles.
- Jun–Oct 2024: 1 600+ public responses; most trade bodies, road-safety groups and fire brigades oppose the change.
- 31 Jan 2025: Government publishes its decision—proposal dropped, UK stays aligned with EU 250 W cap.
⚖️ Why the 500 W Plan Was Shelved
- Battery-fire risk: UK recorded 211 e-bike fires in 2024, prompting calls for tighter safety rules.
- Heavier, faster-accelerating bikes could raise pedestrian-collision severity.
- Insurers warned of higher premiums, undermining the “affordable mobility” goal.
- Cycling bodies argued modern 250 W motors already tackle UK hills when geared correctly.
Bottom line: The 250 W limit remains. A 500 W e-bike is legally classed as a moped—registration, number plate, helmet and insurance required.
🔧 Want 500 W Anyway?
- Type-approve it: Obtain L1e-B certification, then insure and register the bike.
- Ride on private land: Parks, estates or MTB centres that allow motor-assisted cycles.
- Dual-mode kits: Some 500 W bikes can be detuned to 250 W for road use, but tampering voids warranty and insurance.
❓ Quick FAQ
Could a future government revive 500 W plans?
Possibly. The DfT says it will “keep the evidence under review”, but any change needs a new consultation and fresh legislation.
Is a 350 W motor legal on UK roads?
No. Anything above 250 W continuous output bumps the bike into moped territory.
Can I fit a full-throttle to my 250 W bike?
Only if the throttle cuts out above 4 mph; otherwise the bike loses its EAPC status.
