Road Legal (EAPC)

These bikes are built to comply with UK Electrically Assisted Pedal Cycle (EAPC) regulations, meaning they can be used on public roads and cycle paths without registration, tax, or a licence. Motor assistance is limited to 250W and cuts off at 15.5 mph (25 km/h). You can read the official requirements on the UK government website.

Configurable Models

Some bikes are supplied in a restricted, road-legal setup but are capable of higher performance. If modified or used beyond EAPC limits, they may no longer qualify as road legal and could be classified as motor vehicles under UK law. This may require registration, insurance, and a driving licence. For full guidance, please refer to the official UK e-bike rules.

Private Use Only

Certain high-performance models are intended strictly for private land use with the landowner’s permission. These bikes do not meet EAPC standards and cannot be used on public roads, cycle paths, or pavements unless fully registered and insured in accordance with UK law.

If you're unsure which option is right for you, our team is here to help. Feel free to contact us before purchasing for clear guidance and peace of mind.

Every order is shipped with trusted couriers and includes tracking, as explained in our payment and shipping page, so you can follow your delivery from dispatch to arrival.

Shipping Information

Standard UK shipping is free on most bikes. Orders placed after 12 PM may ship the next working day, and some remote areas may have extra delivery charges. If a delivery is missed or returned after failed attempts, additional shipping fees may apply, as detailed in our shipping policy.

14-Day Returns

You can return your bike within 14 days of delivery as long as it is unused, in its original condition, and includes all accessories, manuals, and packaging. Please contact us first before sending anything back, following the steps outlined in our returns and refunds policy.

Refund Policy

Once your returned bike is received and inspected, approved refunds are issued to your original payment method within 2–5 business days. If the item arrives faulty, damaged, or incorrect, we cover return shipping and provide a full refund, as explained in our refund guidelines.

"Customer support was fantastic and helped me pick the right frame size within an hour. Klarna instalments made the purchase stress-free, and the bike’s motor is quiet yet powerful. I’ve already done several long rides and the range is better than expected."
Jacob S. (Bristol)

"My courier was delayed by a day, but BikTron kept me fully informed and even followed up to check delivery. The bike handles hills far better than I imagined and feels solid on longer rides. Overall, very happy with the purchase and the service."
Sophie M. (Leeds)

"Ordering was simple and I loved the clear specs and photos online. The bike arrived well protected, and setup took less than 20 minutes. It rides beautifully — smooth, fast, and stable — and I’m already recommending BikTron to friends who want great value."
