Wisper Tailwind Trail Crossbar Electric Bike 250W

Wisper e-bikes are typically delivered in 2-5 working days from your order date.

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

For full details, please see Wisper's Extended Warranty here.

Some Wisper models offer a choice between a cadence or torque sensor. If available, this will appear as an option above the quantity selector.

With torque sensor technology, your e-bike provides immediate power based directly on your pedal force, delivering exceptional torque and energy efficiency – even on steep hills and rough terrain.

Compared to traditional cadence sensors, which offer power based on pedal rotation alone, a torque sensor intuitively responds to how hard you pedal, giving you a natural and dynamic boost.

This quieter motor design reduces noise while offering up to 15% more range than similar models, allowing you to venture further and enjoy the journey. Whether navigating city streets or tackling off-road trails, torque sensor technology is engineered to elevate every aspect of your ride.

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.

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.

Exclusions

To meet Type Approval requirements, bikes must have front and rear lights operated from a single switch. Currently, models like the Tailwind Trail, Tailwind City, and Wayfarer Mountain cannot be approved due to the lack of lights, but we’re working on a solution to offer these in the future.

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.

Why Choose Wisper Full-Throttle eBikes?

• They provide an eco-friendly, cost-effective commuting solution, ideal for saving on rising fuel and transport costs.
• Better control and increased safety, particularly in slow-moving traffic.
• Instant power when accelerating from traffic lights or hills.
• Great for giving riders a break, especially in hot weather.
• They make cycling more inclusive, enabling people with reduced mobility to enjoy cycling’s benefits.

Costs and Warranty

We offer a complete certification service for £300 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.
