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.

• 2-year warranty on the battery, motor, display and core mechanical components, with lifelong UK-based support from AMPERE

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
