## Description

desertcart.com : Kryptonite Keeper 510 Folding Bike Lock, Compact Lightweight High Security Anti-Theft Foldable Bicycle Lock with 2 Keys and Mount for E-Bikes Scooter Road Mountain Bikes, 100cm (39in) : Sports & Outdoors

Review: Works really great - Best lock I have ever used, e-bike 2 locks works great
Review: Compact and simple to use - I had to graduate from a simple cable lock for my beat-up hybrid bikes to something a little more secure for a modern Class 3 E-bike. This folding lock is moderately secure, enough for shorts stops and more where I ride. The length is sufficient to lock a bike frame around a good size post or other sturdy object, and simple to operate. While it's not light, it's not ridiculously heavy. Most importantly, it easily fits into the side pocket of a small rear rack bag. The lock itself is coated with a soft material so it won't scar your bike during use. Not as secure as a U-lock, but more versatile. And not as heavy or as bulky as a similar size chain lock. Seem like a good compromise between security and weight for those riding in a rural or suburban environment or for short stops for lunch or shopping.

### ⭐⭐⭐⭐⭐ Works really great

Best lock I have ever used, e-bike 2 locks works great

### ⭐⭐⭐⭐⭐ Sturdy and easy to carry and use.
*by M***K on July 2, 2025*

I am rating the lock not Amazon's delivery, so I'll give it 5 stars. The lock is sturdy and easy to mount and use. No, it wouldn't stand up to a grinder, but I never leave the bike out of public sight or for very long. It's not too heavy and fits my folder perfectly. Next day delivery took over a week and a customer service call but other than that it was great.
