Frequently Asked Questions

The one rated for where you park. For an e-bike or good bike left all day, our strongest are the ABUS Steel-O-Chain 9809K (Security Level 12) and the Kryptonite Evolution Mini-9 U-lock (Sold Secure Gold). For café stops, the ABUS Bordo 6000C folding lock (Level 10) is lighter to carry every ride.

Our range runs from $40 for the ABUS Numero 5510C coil cable to about $191 for the Steel-O-Chain 9809K. As a guide, spend more as the bike's value and the theft risk go up. A cheap cable is fine as a second lock but won't stop a determined thief on its own.

It depends on the lock, not the combination. The ABUS Bordo 6000C Combo is a hardened steel folding lock at Security Level 10 of 15. Combination cables like the Kryptoflex 1018 and Numero 5510C are deterrents for quick stops where the bike stays in sight.

Yes. We stock the Kryptonite Evolution Mini-9 U-lock with bracket (Sold Secure Gold), the Keeper 510 folding lock (Sold Secure Bronze) and the Kryptoflex 1018 combination cable. Register your key or combination with Kryptonite's Key Safe or Combo Safe program for replacements.

How to choose the best bike lock

Match the lock to the theft risk. ABUS rates its locks from 1 to 15, Kryptonite from 1 to 10, and some locks also hold an independent Sold Secure rating.

• High risk, all day at the station or the office: the ABUS Steel-O-Chain 9809K, 9 mm hardened chain, Level 12, 2094 g. Or the Kryptonite Evolution Mini-9, a 13 mm U-lock with Sold Secure Gold, 7/10, 1.43 kg, with a frame bracket.

• Medium risk, the commute or the café: the ABUS Bordo 6000C Combo folding lock, Level 10, 90 cm, 1170 g. The Yardo 7807F opens with your fingerprint, Level 8. The Infinity Loop 1806 forms two loops, frame and wheel, Level 6.

• Lower risk, short stops: the Kryptonite Keeper 510 folding lock (Sold Secure Bronze, 5/10, 862 g), the ABUS Microflex 6615K (Level 5, 580 g) and the Steel-O-Chain 5805K (Level 5, 590 g).

• Quick stops and second locks: the ABUS Numero 5510C, a 180 cm coil cable at 508 g, and the Kryptonite Kryptoflex 1018, a 180 cm combination cable rated 1/10.

U-lock, chain, folding or cable?

U-locks give the most security for the weight but need a slim post. Chains wrap around thicker poles, trees and fences. Folding locks pack into a neat block on the frame. Cables are light and long, but they are a deterrent, best used as a second lock to hold a wheel. For the lightest option, the 400 g Bordo Lite 6055K fits in a jersey pocket.

Locking up in Australia

Lock the frame to something fixed, take in a wheel where the lock reaches, and keep the lock off the ground. Near the coast, rinse off salt spray and dry the lock. Kryptonite recommends silicone, graphite or Teflon-based lubricant a few times a year, not WD-40. Combination and fingerprint locks suit families sharing bikes: nobody hunts for a key. See the rest of our bike gear, including bike lights for the ride home.
