The Wisper Tailwind Comfort Crossbar Electric Bike, a versatile and reliable e-bike designed to enhance your riding experience. With its powerful motor, efficient battery, and high-quality components, the Tailwind delivers performance and comfort in one package.

Equipped with a Wisper high-efficiency, 250W hi-torque brushless motor, this bike effortlessly reaches speeds beyond 15.5mph while maintaining minimal motor drag. The standard thumb throttle provides two options: a speed of up to 4mph (6km/h) and a speed of up to 15.5mph (25km/h) when pedalling. Additionally, a full throttle option is available for those seeking maximum power.

The lithium standard slimline 360Wh or long-range 540Wh battery options offer impressive range capabilities. The 360Wh battery provides a maximum range of 50 miles (80km), while the 540Wh battery extends the range to 70 miles (110km). Please note that using the throttle-only function may reduce the range by up to 30%. However, it is recommended to pedal whenever possible to optimize range and performance.

Controlling your ride is made easy with the Wisper backlit LCD display, featuring remote controls for convenient access. The lightweight and sturdy frame, made from Wisper Tailwind 6061 alloy, offers durability and stability. The custom butted tubing, tapered headtube, internal cable routing, and replaceable hanger contribute to the overall strength and reliability of the bike.

Mudguards made from custom-made aluminium keep you protected from splashes and debris, while the alloy twin blade fork ensures a smooth and controlled ride. The Shimano Alivio 9-speed derailleur and rapidfire shifter deliver seamless gear changes, and the KMC X9 rust-resistant chain ensures durability and longevity.

Featuring an alloy super-bright front light and a rack-mounted rear light, both powered by the bike's battery, you can ride with confidence and visibility, even in low-light conditions. The Wisper Comfort saddle and ergonomic handlebar provide optimal comfort during long rides, and the Wisper hydraulic disc brakes offer reliable stopping power.

The Wisper Tailwind Comfort Crossbar Electric Bike features alloy black anodized double-wall wheels with Kenda 27.5" x 2.2" high puncture-resistant tyres, ensuring a smooth and stable ride on various terrains. The rear rack, made from lightweight aluminium, can support a load of up to 15kg and includes a cable tidy for added convenience.

Experience the joy of riding with the Wisper Tailwind Comfort Crossbar Electric Bike. With its exceptional performance, comfort features, and reliable components, this e-bike is your ideal companion for daily commutes, weekend adventures, and everything in between.


Full Throttle Add on (+ £299) - UK LEGAL (Please note it will take between 6-8 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. 


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.
