## Description

Rated at a 5 / 10 on our security scale, it is good for quick stops in a metropolitan area, a few hours in the suburbs or overnight in rural areas. The hardened deadbolt design provides extra holding power and the disc-style cylinder is both pick and drill resistant. The lock comes with two new ergonomic "I" keys and a weather-resistant nylon sleeve to prevent scratches. The lock is 120 cm long and weighs 3.75 lbs.

Review: Throw it over your shoulder and ride. Not super heavy but a solid deterant. - Exactly what I was hoping for. the roughly 4' length allows me to simply throw it over a my head and carry it across my torso so the bike itself does not feel any heavier. Keyless is a huge plus as I don't like to have to carry a set of keys with me. Form, function, durability.....easy to use. What else could you really ask for in a bike lock. Did I mention if your bike is stolen they have a $500 cash back?
Review: Good Bike Lock for Medium Security Needs - Good bike lock for medium security needs. I wouldn't use it for an extended time period like overnight outside in a poorly lit area. Open end fits through the loop of a cable allowing additional protection of wheels and frame. It's heavy but that's a good thing!
