Frequently Asked Questions

It rates 7 out of 10 on Kryptonite's own scale and holds Sold Secure Bicycle Gold. The 13 mm shackle is hardened steel built to resist bolt cutters and leverage, a double deadbolt resists twist attacks, and the disc cylinder is pick and drill resistant. It is a serious everyday lock for a good commuter.

The KryptoFlex 410 is 120 cm of 10 mm braided steel with a loop at each end and no lock of its own. Thread it through your wheels or saddle, feed both loops over your U-lock shackle and lock up, so the whole bike is tied together. It works with a U-lock, disc lock or padlock.

Only for short stops where the bike stays in view. Kryptonite rate the KryptoFlex 1018 combo cable at 1 out of 10 and class cable locks as deterrents. For a bike left for hours in a public rack, lock the frame with a U-lock like the Evolution Mini-9 and use a cable for the wheels.

The Kryptonite locks we stock

• U-lock: the Evolution Mini-9 has a 13 mm hardened steel shackle and a double deadbolt against twist attacks. It rates 7 out of 10, holds Sold Secure Bicycle Gold and comes with a frame bracket and three keys. It weighs 1.43 kg.

• Folding lock: the Keeper 510 opens to 100 cm, rates 5 out of 10 and holds Sold Secure Bicycle Bronze, at 862 g with a frame bracket.

• Combination cable: the KryptoFlex 1018 is 180 cm of 10 mm cable, rated 1 out of 10: a deterrent for a stop where the bike stays in view.

Which one for your ride

For a commuter bike at a Brisbane CBD rack all day, use the Evolution Mini-9 through the frame and add the KryptoFlex 410 for the front wheel. For a café stop on a Sunday ride, the Keeper 510 or a cable is enough. Compare with ABUS chain and folding locks on bike locks.
