The KryptoLok Standard pairs a 12.7 mm hardened steel U-lock with a 120 cm KryptoFlex cable, so you can lock your e-bike's frame with the shackle and loop the cable through a wheel or an accessory. It is rated Sold Secure Gold.
A double deadbolt guards against twisting and prying attacks, the cylinder resists picking and drilling, and a vinyl coating protects your frame. It holds Police Preferred Specification status from Secured by Design, and comes with Kryptonite's Lifetime Warranty, Key Safe programme and optional Anti-Theft Protection Offer.

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.
- Kryptonite Lifetime Warranty, with the Key Safe programme and the optional ATPO (Anti-Theft Protection Offer)
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
