Freqently Asked Questions

We’ve put together answers to the most common questions about our electric bikes and scooters. If you can’t find what you’re looking for, please contact us and we’ll be happy to help.

E-Bikes and the Law

Are your e-bikes road legal in the UK? Yes. All of our e-bikes meet the UK EAPC (Electrically Assisted Pedal Cycle) regulations:
Maximum motor output: 250W
Motor assistance cuts out at 15.5 mph (25 km/h)
Must be pedalled to engage motor assistance (with throttles restricted to walking speed without pedalling)
What is the minimum legal age to ride an e-bike? You must be at least 14 years old to ride an EAPC on UK roads.
Where can I ride an e-bike? You can ride anywhere a normal bicycle is permitted, including roads, cycle paths, and shared-use trails. You cannot ride on pavements unless marked as cycle routes.
What about privately-owned e-scooters? Currently, privately-owned e-scooters are not legal on public roads, pavements, or cycle lanes in the UK. They can only be used on private land with the landowner’s permission.

Orders, Delivery & Returns

How long does delivery take? Delivery typically takes between 3–7 working days, depending on stock levels and your location. We’ll provide tracking once your order has shipped.
Do you charge for delivery? Most orders qualify for free UK mainland delivery. Some remote areas or special items may incur a small charge (details at checkout).
Can I return my order? Yes. We offer a 14-day return window for unused items in their original packaging. Please see our Returns Policy for full details.
What if my bike arrives damaged or faulty? Contact us immediately with photos of the issue. We’ll arrange repair, replacement, or refund in line with our warranty and returns policy.

Warranty & Support

Generally, bikes come with a 1 year warranty which covers all the major parts. But not consumables such as tyres.  But please see each bike for more details.

Batteries & Charging

How far can I ride on a single charge? Range depends on the model, terrain, rider weight, and assist level. Most e-bikes in our range cover 25–60 miles per charge.
How long does charging take? Charging usually takes 4–6 hours with the supplied charger.
Can I replace the battery? Yes. All of our e-bikes use removable lithium-ion batteries that can be swapped or upgraded.

Maintenance & Repairs

Do I need to service my e-bike? Yes. Just like a regular bike, you should service it regularly to keep it safe and efficient. We recommend:
Basic check-up after 150 miles
Annual service for regular riders
Can I get my bike repaired at a local shop? Most bike shops can handle e-bike servicing. For electrical issues, it’s best to use an authorised service partner.

Payments & Finance

What payment methods do you accept? We accept major credit/debit cards, PayPal, and Klarna/finance options (where available).
Do you offer finance? Yes. You can spread the cost of your e-bike with monthly instalments. See checkout for details.

Other Questions

Do I need insurance or a licence for an e-bike? No. EAPCs do not require insurance, tax, or a driving licence in the UK.
Do I need to wear a helmet? Not legally, but we strongly recommend wearing a helmet and protective gear for your safety.
Can I test ride a bike before buying? Please contact us to see if we can arrange a demo or advise on local dealers/trails.

What people like

This ultra-lightweight electric bicycle is highly regarded for its sleek carbon fiber construction and natural riding experience. Reviewers appreciate the inclusion of a torque sensor and a low-maintenance belt drive, which contribute to a quiet and responsive commute. While its weight makes it easy to carry into apartments or onto transit, the rigid frame and integrated battery are noted as trade-offs for its minimalist design. It is seen as a premium, stylish urban commuter that balances performance with aesthetic appeal.

Pros

  • Lightweight Carbon Frame: The frame construction makes it incredibly light and easy to carry up stairs or onto public transportation compared to standard models.
  • Responsive Torque Sensor: Reviewers praise the smooth and natural power delivery that adjusts instantly to the rider's pedaling force for an intuitive feel.
  • Low Maintenance Belt: The carbon belt drive is highly valued for being silent, grease-free, and requiring far less upkeep than a traditional metal chain.
  • Sleek Minimalist Aesthetic: Its integrated battery and hidden wiring provide a clean look that closely resembles a traditional premium road bike rather than an e-bike.
