Sigtuna’s Folding BIke Locks is one of the few folding locks we’ve tested on Crank Boutique, although the mechanism is broadly the same as locks available from manufacturers such as Abus. A number of coated steel alloy bars are held together by secure pins with a tumbler lock at one end. This construction also allows for a number of the same locks to be linked together to provide a longer lock length.
Based on our testing a single Sigtuna folding bike lock was sufficient to put around the bike, frame and the standard bike stands dotted around Sydney. A single lock should be sufficient for most unless you’ve got particularly large MTB tyres or are riding a fat bike. The lock was well built and sturdy and we think should be able to fend off most casual attacks.
What wasn’t so great were the provided velcro straps or the bottle cage mounting. We found the straps provided with our lock weren’t really up to holding the weight of the lock for anything more than short journeys. We also struggle with mounting it on our cage mounts.
The team at Crank Boutique always ride with bags when they commute, so the mounting issues are easy to overlook and the lock comes recommended. However, if you’re looking for something to attach to your bike it’s something to keep in mind.
