Can I derestrict my electric bike?
No. A legal pedal-assist electric bike (VAE) has its assistance cut at 25 km/h and a motor limited to 250 W. Derestricting a VAE (removing the 25 km/h limit) takes it out of the 'bike' category: it becomes a moped (or motor vehicle) that should then be approved, registered, insured, and ridden with a helmet and the matching licence. Since a derestricted VAE isn't approved for this use, riding it on the public road is illegal and dangerous. A bike with assistance up to 45 km/h (speed bike) is already subject to these obligations.
📋 The rules
- Legal VAE: assistance cut at 25 km/h, motor ≤ 250 W
- Derestricting = the bike becomes an unapproved moped
- Should then apply: approval, registration, insurance, helmet
- Riding a derestricted VAE on the public road is illegal
- Speed bikes (up to 45 km/h): already subject to these obligations
🔓 Exceptions
- Use on closed private land (off the public road): outside the Highway Code
- Approved speed bikes: allowed with registration, insurance, helmet
- Start assistance up to 6 km/h (without pedalling) stays tolerated on a VAE
⚠️ Penalties & fines
Riding a derestricted VAE (thus unapproved) amounts to driving a non-compliant motor vehicle: no insurance (€3,750), no approval/registration and helmet, with possible confiscation. Making, selling or modifying derestricted cycles can be very heavily punished (up to €30,000 fine). In a crash, the insurer can refuse to cover a modified machine, leaving you financially liable.

❓ Frequently asked
Can you derestrict an electric bike?
No. Derestricting a VAE takes it out of the bike category: it becomes an unapproved moped. Riding it on the public road is illegal, as it would then need approval, registration, insurance and a helmet.
What's the legal limit of a VAE?
The electric assistance must cut at 25 km/h and the motor be limited to 250 W. Beyond that it's no longer a pedal-assist bike in the legal sense, but a motor vehicle subject to other obligations.
What's the risk with a derestricted VAE?
Riding an unapproved machine: no insurance (€3,750), no approval and helmet, with possible confiscation. Modifying or selling derestricted bikes can be punished up to €30,000.
Does my insurance cover a derestricted VAE?
No, generally. In a crash the insurer can refuse to cover a modified, unapproved machine, leaving you financially liable for the damage, including bodily injury. The risk far exceeds a simple fine.
And a 45 km/h speed bike?
A bike with assistance up to 45 km/h (speed bike) is already treated as a moped: it must be approved, registered, insured, and ridden with a helmet and the right licence. It's not an ordinary VAE.
