A folding lock trades outright strength for reach and portability. The KryptoLok 610 S folds down to a compact block that clips to your frame, then opens out to 100 cm: long enough to get around a lamp post, a thick stand or a rack that a U-lock will not reach, without carrying a chain.
It is rated Sold Secure Bronze, the entry level of Sold Secure's four bicycle ratings. That makes it a good second lock, to secure a wheel or for a short daytime stop somewhere busy. It is not the lock to rely on for an e-bike left on a city street or overnight: for that, choose a Sold Secure Diamond U-lock, ideally with a ground anchor at home.

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)

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.
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
