What You Need
- A hardened U-lock (the main lock)
- A cable or second lock for the front wheel
- A solid, fixed object to lock to
- BUILT TO LAST: The Kryptonite Evolution Mini‑7 U‑Lock is constructed with a 13mm hardened Max‑Performance steel shackle to help resist cutting and leverage attacks, while a durable vinyl‑coated protective sleeve prevents scratches to your bike’s frame and preserves its finish.
- DOUBLE-DEADBOLT DESIGN: Locks the shackle on both sides of the crossbar for enhanced resistance against twisting and pulling. Certified by Sold Secure Gold, it also includes a high‑security disc‑style cylinder to resist picking and drilling
- VERSATILE SECURITY WITH 4‑FT CABLE: Includes a 4‑ft (120 cm) double‑loop security cable ideal for securing your front wheel, helmet, or accessories. Together with the U‑lock, it is perfect for securing bicycles and e‑bikes at work, school, or around town
- COMPACT, COMMUTER-FRIENDLY SIZE: This U-lock features interior locking dimensions of 3.25” x 7” (8.3cm x 17.8cm) and a total lock weight of 3.55 lbs (1.61 kg), providing a tight fit around bike racks to deter leverage attacks. Weather-treated components help protect against rust and outdoor exposure for reliable everyday use
- EASY MOUNTING BRACKET INCLUDED: Comes with a secure FlexFrame‑U bracket that attaches directly to your bike frame for hassle‑free transport—allowing you to carry the lock easily with no backpack or lock bag required
The Kryptonite Evolution Mini-7 (about $105) includes both a small U-lock and a front-wheel cable, so it covers this whole method.
Step-by-Step: Locking a Bike Properly
- Park next to a fixed rack or pole. Put the bike close enough that the lock fits around the object and the frame without strain.
- Lock the rear wheel and frame together. Put the U-lock around the rear wheel rim, inside the rear triangle of the frame, and around the rack. This is the method described in Sheldon Brown’s lock strategy guide. Because the wheel can’t pass through the frame, the lock secures both the wheel and the frame.
- Or lock the frame directly. If the shackle is big enough, go around the seat tube or down tube and the rack. Many riders do both when they carry two locks.
- Secure the front wheel. Run a cable through the front wheel and loop it onto the U-lock, or use a second U-lock. Quick-release front wheels are easy to steal.
- Fill the shackle. Leave as little empty space inside the U-lock as possible. Empty space lets a thief fit a jack or lever inside.
- Keep the lock off the ground. A lock resting on the ground can be hit or crushed. Position the keyhole facing down so it’s harder to reach.
- Take removable parts. Remove lights, bike computers and quick-release seats, or secure them.
Common Mistakes
- Locking only the front wheel. A thief can unbolt the wheel and walk away with the rest of the bike.
- Using only a cable lock. Cables can be cut quickly.
- Locking to something that can be lifted off. Short posts and loose signs can be lifted over.
- Leaving a gap in the shackle. A loose U-lock is easier to lever open.
Lock Types and Where They Go
| Lock | Where to put it |
|---|---|
| U-lock | Rear wheel inside the frame triangle, or around the frame |
| Chain | Through the frame and rear wheel, kept off the ground |
| Cable | Through the front wheel, looped onto the main lock |
| Folding lock | Around the frame and the rack |

FAQ
Should I lock the frame or the wheel?
Ideally both. The rear-wheel-in-frame method secures both with one U-lock, and a cable or second lock covers the front wheel.
How do I lock a bike with quick-release wheels?
Use a cable or second lock for the front wheel, or replace quick-release skewers with locking skewers.
Does locking technique really matter?
Yes. A strong lock used poorly, such as through the front wheel only, can be defeated in seconds without breaking the lock.
