The UK’s Ultimate Folding Electric Bike

The latest evolution of our flagship folding e-bike, the Tailwind 806, is more versatile than ever, allowing you to tailor it to your exact needs.

Designed for campers, caravanners, boating enthusiasts, commuters, and those with limited storage space, the Tailwind 806 offers the perfect blend of convenience and performance. Its ultra-low step-over height makes it ideal for shorter riders, while the adjustable seat post and handlebar stem ensure a comfortable fit for taller riders—suitable for heights ranging from 4'6" to 6'6"!

Built for long-distance reliability, the Tailwind 806 features a robust folding mechanism that eliminates frame twist, delivering a stable and smooth ride comparable to a traditional non-folding bike. Customise your ride with a choice of battery range, setup options, add-ons, and colours.

Meet the Tailwind 806: Versatility Redefined

Inspired by the award-winning Traditional 806, the Tailwind 806 has been engineered to be more adaptable than ever, making it a truly versatile folding e-bike with light cargo capabilities.

With a redesigned rear rack and optional front rack, the Tailwind 806 offers increased cargo capacity. The rear rack has been designed to accommodate panniers, baskets, and child seats, while new bottle cage mounts provide the option to fit a standard water bottle holder or other accessories such as integrated bike locks.

Available in two drive options—Cadence Sensor (Tailwind 806) or Torque + Cadence Sensor (Tailwind 806 Encore)—alongside two battery sizes, three colours, and an off-road Venture Pack upgrade, the Tailwind 806 micro-cargo platform can be customised to suit any rider’s needs.

GO BEYOND THE FOLD

The Encore model offers a little more refinement, with high quality Schwalbe Big Ben road tyres, giving you additional comfort over rougher surfaces and excellent grip on smoother roads.  

The benefit of a central double stand for stability when parked. Five levels of torque-controlled power and one cadence giving the 806 Encore rider smoothly delivered range when needed or effortless cruising power on longer runs. 

Venture Pack: Take the Road Less Travelled

For those who enjoy adventure, the Venture Pack Upgrade transforms both the Tailwind 806 and Tailwind 806 Encore into an off-road-ready e-bike. This upgrade includes:

Schwalbe Marathon 365 Tyres – Designed for all-season grip, including cold, wet, and even snowy conditions, with added GreenGuard puncture protection.
Tannus Armour Tyre Inserts – Provides 90% puncture prevention, run-flat capability, and extra rim protection.
Alloy Front Rack – A durable black alloy rack with a 7kg load capacity, secured with a triple frame mount for added stability. (Also available separately for £49.99.)

Whether you're commuting, adventuring, or simply exploring, the Tailwind 806 is designed to adapt, perform, and go the distance.

Full Throttle optional add on (+£299) - CURRENT WAIT TIMES 6-8 WEEKS - UK LEGAL (Please note it will take between 2-8 weeks from your order date to have your bike tested by the DVSA and then delivered to you. Using your Wisper bike on throttle only will reduce your range by up to 30% and the TTP will not help increase range whilst you are using the throttle only. If your bike has been upgraded so it works on the throttle only, we still suggest pedalling when you are able to do so. Use the throttle only function when you need to rest or to help you pull away when setting off.

The use of a full throttle on an electric bicycle is legal in the UK on the condition that the bicycle has been tested, and approved by specific DVSA centres. The correct approval certification must have been issued by the DVSA. The approval certificate must show the bike’s make, model and frame number.

Without the correct certification electric bicycles with a throttle may not legally be used anywhere in the UK where the public has access. This includes private land where a footpath runs across or adjacent to the land.


 

How is the frame size measured?

Most E-bikes are measured from the centre of the crank to the base of the seat post tube. However, some E-bike manufacturers may measure their bikes differently depending on their style.

Wisper806 purchase from ecobike company.

Bike brilliant, purchase from ecobike very good until transfer of money. Then nothing, re shipping, delivery time, after sale follow up etc. Took the edge off the experience, hence only 4 star.

Excellent quality kit

This bike is so easy to ride that it has replaced my car for all trips less than 50 miles!
The combination of gears and motor was enough for Cornish hills even with a gale force wind blowing towards me!
The throttle feature is super helpful for traffic lights and hill starts too!
It has held up even on muddy roads, questionable bridleways, and city centres during stormy conditions when I've been caught out unexpectedly!
Overall, an honestly brilliant piece of kit!

Brilliant up hills

Very well made and good looking folding e-bike. Could not believe the help it gives up steepish hills. High recommend the full throttle option - what fun!! Marvellous post sales service from Eco Bike - very quick and pleasant staff on the phone.

Great product and great company

The bike turned out to be everything we hoped for. There was a small mix-up with the supply of the product. Sasha from Eco-Bike company went above and beyond to correct this issue. Daily updates and super communication via email and telephone supported me to a very satisfactory conclusion. If you’re looking for an e-bike go to Eco-Bike company, you will be in good hands!

Fantastic folding e-bike - love it!

This is a fantastic ebike! I bought the torque version and it delivers everything promised and more. The push you get when you set off is marvellous. With the other ebikes I had (Popal, Radrunner), I had difficulty setting off, always felt nervous if I had to stop half way up a steep hill. Now I can relax! I get a workout and if I can't manage anymore (and sometimes I can't - I'm in my 70s and only took up riding again a year ago) I can use the throttle. You still have to keep pedalling but I (almost) fly. In comparison to cadence sensor bikes (which I had before), you have to work harder but the reward is great. I can breathe better. I am noticeably much less out of breath than I used to be. As you can gather, I'm an older, unfit person, who is enormously grateful for Wisper's technology. I am grateful, too, to the staff at Ecobike, especially to Jarred who has always been immediately helpful and ever patient. In addition to the marvellous customer service, the prices cannot be bettered.

We love our new bikes !

We love our new bikes ! Thank you very much for the excellent customer care and the ease of ordering . If you’ve been debating with yourself whether to get yourself an ebike I would say to you ...do it ! I’m in my sixties with asthma and was a bit worried that I would still be puffing and struggling but far from it , long rides are a doddle ! Total game changer ! The bike itself, mine is the 806 folding one , is well built and comfortable to ride .

We love our Whisper electric folding…

We love our Whisper electric folding bikes. The retailer support is excellent and we are thoroughly enjoying this new experience. The bikes themselves appear to be very well and solidly built. We have only had them a month, but they appear to do everything they claim. The paint finish is excellent, with the colour eliciting many compliments. We are 'senior' (in age not cycling terms) and have chosen to upgrade to the largest softest saddles we could find and a gear lever which better fitted our preferences. If you are looking for a step through, folding e-bike we can say we are delighted with our Whispers.

Great e-bike easy to mount

The Wisper 806 is an excellent e-bike. As an older person of no great stature, getting on and off a bike needs to be easy and safe. Unlike many other folding bikes the main frame centre bar is curved downward making it very low and therefore it is an easy step-thru to mount. The 3 levels of Assist are perfectly adequate though I find that level 1 is sufficient for most riding. There is a quick burst control which immediately pulls you up anything steep. It's a twist grip control on the far right of the left handlebar. Mind you don't catch it when standing and holding the handlebar. Lights are included (all bikes should have these) and are easy to switch on via the illuminated LED screen. There is a disc brake on both the front and rear wheel which I haven't seen on any other folding e-bike. Folds up easily too, though there isn't a magnetic catch for holding the two wheels together. You need to use a strap to do that. They do include a luggage strap. Wisper bikes have also sent us some helicopter tape to protect the frame from scratching when folded. The only reason I haven't given full 5 stars is because I've had difficulty getting luggage for the rear rack. They do include a large elastic luggage strap similar to a bungy to tie a bag on; but I wanted to fit a proper rack bag. There is no space between the rack itself and the battery to thread through any locating straps for a top of rack bag. With the fantastic customer service they provide and the quality and features of this bike, I would recommend it to anyone. Both myself and my husband use it to cut out using the car for shorter journeys. But it's great fun too.
