A bike lock is designed to protect your beloved bike from brazen thieves. In other words, even those who really want to steal the bike. Those who opt for a thick chain lock often believe that they have a particularly secure lock. The Crivit combination lock with chain also looks as if it can withstand brutal attempts to break it open, but it is also suspiciously light. We wanted to find out what the chain lock can really withstand under its plastic casing and put the bolt cutters to work.
The Crivit bicycle chain lock costs a favourable 4.99 euros (one or two euros more than the current locks at Aldi) and promises protection against bicycle theft. The 6 mm chain links are encased in a textile cover and appear somewhat delicate; the lock weighs 940 grams in total. That is relatively light. The freely encodable 5-digit numerical code enables uncomplicated handling and is easy to set. With a length of 117 cm, the lock can be used flexibly and the textile cover protects it from scratches.
The Crivit bike chain lock for €4.99 offers simple basic protection for short stops and everyday journeys. The robust 6 mm chain links are encased in a textile cover and the freely encodable 5-digit numerical code makes it easy to use. With a length of 117 cm, the lock can be used flexibly and the small handles on the left and right make handling easier.
Although the Crivit combination lock from Lidl costs one or two euros more than the Aldi locks, it remains a very affordable chain lock. The first impression is not deceptive: the thin six millimetre chain links and the low weight cast doubt on the security - and this is exactly what our practical test confirmed.
A bolt cutter was used just once and the chain was cut immediately. This makes it clear that this lock only offers basic protection for very short stops, such as outside the bakery or kiosk. It is unsuitable for overnight parking, for the bicycle cellar or generally for places with a higher risk of theft.
It is also important to look at insurance policies: Many bicycle theft policies require a certain security class. The Lidl combination lock does not fulfil these requirements. In the event of an emergency, there would therefore be no reimbursement. The Crivit combination lock is therefore a typical discounter product: practical, light and cheap, but only intended for occasional stops - not for real theft protection.
