Wisper Tailwind 806 Folding E-Bike

Introducing the Tailwind 806

Built on the heritage of our award-winning Traditional 806, the Tailwind 806 is now more versatile and capable than ever. This latest model is a highly adaptable folding electric light-cargo bike designed to suit a wide range of uses.

With its redesigned rear rack and optional front rack, the new 806 offers significantly increased cargo capacity. The rear rack has been purpose-built to accommodate panniers, baskets, and child seats with ease. The bike also now features bottle-cage mounts that can support a standard bottle cage or a wide selection of accessories—such as locks—that utilise the same mounting system.

Available with either a cadence-sensor setup (Tailwind 806) or a combined Torque and Cadence system (Tailwind 806 Encore), two battery capacities, three colour options, and the off-road Venture Pack, the Tailwind 806 micro-cargo platform can be tailored to suit any rider’s requirements.

Venture Pack: Embrace the Road Less Travelled

For riders seeking adventure, the Venture Pack upgrade transforms both the Tailwind 806 and Tailwind 806 Encore into capable off-road e-bikes. This comprehensive kit includes:

• Schwalbe Marathon 365 Tyres – All-season tyres with reliable grip in wet, cold, and even snowy conditions, reinforced with GreenGuard puncture protection.
• Tannus Armour Tyre Inserts – Delivers up to 90% puncture prevention, run-flat functionality, and added rim protection.
• Alloy Front Rack – A sturdy black alloy rack with a 7kg load capacity, mounted securely with a triple frame fitting. (Also available separately for £49.99.)

Whether you’re commuting, adventuring, or simply enjoying the journey, the Tailwind 806 is built to adapt, perform, and go the distance.

Max Speed

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 ebike, please add the throttle upgrade (click here) to your cart.

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. To meet Type Approval requirements, bikes must have front and rear lights operated from a single switch (such as this one).

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.

As of November 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.

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.

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

Suitable for riders between 4’6″ and 6’6″

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

The UK Cycle to Work Scheme is a government initiative (salary sacrifice) aimed at promoting healthier lifestyles and reducing environmental impact.

It allows employees to save money and commute with a new bike and accessories, spreading the cost over tax-free monthly instalments through your employer, potentially saving you up to 47% of the cost. It's a brilliant way to get an e-bike without breaking the bank!
