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 all-terrain electric bike is widely praised for its exceptional power and hill-climbing capabilities, particularly noting a high torque output that exceeds typical expectations for its legal motor class. Users appreciate the dual-sensor system, which offers a customizable riding experience between a natural, responsive pedal feel and effortless cruising. The sturdy frame and large fat tires provide a stable and commanding presence that handles both urban streets and muddy trails with ease. While the ride quality is highly regarded for its smoothness and stability, common feedback highlights the bike's substantial weight and the omission of certain standard accessories. Safety is frequently cited as a strong point, with reviewers consistently mentioning the responsiveness of the hydraulic braking system and the high visibility of the lighting.

Pros

  • High Torque Output: The motor delivers a remarkable 80-95 Nm of torque, allowing it to conquer steep inclines and challenging off-road conditions with significantly less effort than competitors.
  • Dual Sensor System: Riders can switch seamlessly between torque and cadence sensors, providing the flexibility to choose between a responsive, natural pedaling feel and a more relaxed cruise.
  • Reliable Hydraulic Brakes: The high-quality hydraulic disc brakes offer powerful and consistent stopping force, ensuring rider confidence and safety in various weather and terrain conditions.
  • Robust All-Terrain Design: A sturdy step-over frame paired with 4-inch fat tires ensures excellent stability and comfort, making it a versatile explorer for both city commutes and rugged trails.
