Are e-bikes legal in the UK and where are you allowed to ride them?

Yes, e-bikes that meet EAPC (Electrically Assisted Pedal Cycle) regulations
are legal and can be ridden without a licence, insurance or vehicle tax.

e-bikes can be used on public roads, cycle paths, and anywhere
regular bicycles are allowed but not on pavements.

Do I need a licence to ride an e-scooter?

Privately owned e-scooters are currently illegal on public roads but rental
e-scooters require at least a provisional driving licence.

Do you offer warranties and after sales support?

Yes absolutely! All our products come with a manufacturer’s warranty and our
customer service team is here to assist with any issues.

How long does it take to fully charge an e-bike battery and how far can you travel?

Charging times vary depending on the model and battery capacity but most e-bike batteries take between 3 to 6 hours to fully charge. On a full charge, you can typically expect a range of 30 to 100 miles depending on factors like terrain, rider weight and level of pedal assistance.
