A crossover electric bike — enough tyre for a canal towpath or a forest track, and enough lights, mudguards and rack for the ride to work on Monday morning. Its 27.5 x 2.20 inch KENDA tyres are wider than a road bike's and narrower than a fat bike's, which is the sweet spot for a rider who meets tarmac, gravel and the odd pothole in the same journey.
A 48V 500W rear hub motor pulls strongly away from a standstill, and the 48V 13Ah lithium battery lifts out of the down tube so you can charge it indoors and leave the bike in the shed. Mechanical disc brakes on 180mm rotors give confident stopping in the wet with far less hand effort than cable brakes.

Some models, such as UTO's folding e-bikes, come in one frame size; that model's Specifications list the rider heights it fits.
Charts are a starting point — frame geometry varies by model, so use it as a guide only.
Free standard delivery is available to most mainland UK addresses on qualifying e-bike orders. Highlands, islands, Northern Ireland and remote postcodes may cost more or take longer, and we confirm this before dispatch. Your e-bike is securely packaged for transport, and we send the available tracking information once it is on its way. Full details are on our Free UK Delivery page.
All our e-bikes come to us from UK and European makers and wholesalers, and are covered by the manufacturer's warranty. If you ever need to send something back, please contact us first so we can arrange the return.
- Carries a 12 month warranty, or longer if you took the extended warranty
Your employer buys the e-bike; you repay it from your gross (pre-tax) salary over 12–18 months. Because the payments come out before tax and National Insurance, most riders save 25–40% versus the sticker price. At the end you keep the e-bike for a small final payment.
- You are eligible if you are employed, earn above the National Minimum Wage after the deduction, and your employer runs a scheme (Cyclescheme, Green Commute Initiative and others)
- There is no longer a £1,000 cap for most schemes
- Self-employed, or want the simplest option? Interest-free finance and Klarna — Buy Now, Pay Later spread the cost at checkout, with no employer needed
