Kryptonite's New York range is the lock to buy when your e-bike is worth protecting properly. The long shackle reaches around the frame and a wheel at a stand or rack, without leaving the slack a thief needs to get a tool in.
It is rated Sold Secure Bicycle Diamond, the top of Sold Secure's four bicycle levels. Sold Secure say Bicycle Diamond and Powered Cycle Gold are tested to the same standard, with the same tools, attack methods and time limits, which makes it the level worth having for an e-bike. Insurers set their own minimum, so check your policy wording, but Diamond sits at or above what UK cycle policies ask for.

Match the frame size to your height using the chart below, then set your saddle height so your leg is almost straight at the bottom of the pedal stroke. If you are between sizes or have any mobility concerns, size down or choose a step-through frame.
- 4'10" – 5'2" — 13" – 14" (XS)
- 5'2" – 5'6" — 15" – 16" (S)
- 5'6" – 5'10" — 17" – 18" (M)
- 5'10" – 6'1" — 19" – 20" (L)
- 6'1" – 6'4" — 21" – 22" (XL)
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.
- Lifetime limited warranty against defects in materials and workmanship, to the original owner
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
