We're excited to continue leading the way in innovation and progress within the e-bike industry by offering fully UK-legal, full-throttle eBikes that can reach up to 15.5mph without pedalling.

To add this option to your bike, please add the throttle upgrade (click here) to your cart at checkout.

These full-throttle eBikes not only enhance safety and control at lower speeds but also provide faster acceleration from a standstill. They make cycling more accessible to those who need a little extra assistance, whether they're discovering or rediscovering the joy and freedom that cycling offers.

How It Works

When you order a Wisper full-throttle eBike, we’ll arrange for it to be tested by the DVSA and approved as an L1e category 250W Low Powered Moped. This process can take 2-8 weeks, as the bike needs to be inspected at an approved MVSA centre for Single Vehicle Approval (SVA) tests.

As of October 2025, wait times are approximately 10-12 weeks from your order date due to the time it now takes to book a slot with the DVSA for type approval.

At Bike Yard Online, we can now deliver Wisper e-bikes without the throttle so you can start riding straight away instead of waiting 2–3 months for delivery. Once your bike is with you, contact us and we will arrange a DVSA slot to fit the legal throttle at a later date. When the time comes, just send the bike back and we will handle everything. If this suits you, please get in touch before ordering to confirm compatibility.

These tests ensure that the eBike complies with current Electrically Assisted Pedal Cycle (EAPC) regulations. After the test, we receive a British National Type Approval certificate, which is specific to your bike’s frame number. This certificate is valid for the bike's lifetime and doesn’t require renewal, unlike an MOT.

When not using the throttle, the bike functions like a standard eBike, with no impact on regular EAPC features.

Eligible Bikes

To meet Type Approval requirements, bikes must have front and rear lights operated from a single switch. As of 2025, the following bikes are eligible:

• Tailwind 806 Encore Folding eBike
• Tailwind 806 Folding Electric Bike
• Tailwind Comfort Crossbar E-Bike
• Tailwind Comfort Low Crossbar E-Bike
• Wisper 705 26″ Step-Through E-Bike
• Wayfarer H9 Hub-Drive Crossbar 43 V E-Bike
• Wayfarer H7 Hub-Drive Step-Through 43 V E-Bike
• Wisper 905 Crossbar Touring E-Bike
• Wisper 705 24″ Step-Through E-Bike

The Regulations

L1e electric bikes are classified as Low Powered Mopeds, adhering to the Electrically Assisted Pedal Cycle Regulations of 1983, updated in 2015. The key requirements are:

• Must have pedals capable of propelling the bike.
• The electric motor must not exceed 250 watts and cannot power the bike beyond 15.5mph.

Once Type Approved, these bikes can legally be ridden on UK roads and private land at speeds up to 15.5mph using just the throttle.

Costs and Warranty

We offer a complete certification service for £299 with new bikes purchased from us. This includes the test fee, software upgrade, transportation to the test centre, and a £45 fee to extend the warranty to cover throttle use.

If you're taking your Wisper bike abroad, it’s your responsibility to check the local legal requirements. Wisper can re-restrict your bike for a £55 fee at their HQ in Kent and de-restrict it when you return.

Please Note:
Using the throttle can reduce your e-bike’s range, so for maximum distance, it’s best to use it only when needed.

Wisper e-bikes are typically delivered in 2-6 working days from your order date.

Riders over 6ft (182cm) tall, please ask for 400mm seat-post when ordering.

All Wisper e-bikes come with a comprehensive two year warranty on electrical and bike parts with five years on frames.
