We live in the middle of the big city and bicycle theft is part of its daily life, why should new bike for my daughter a decent castle ago. We decided for this one of Abus in the long version (110 cm), so you can always laid somewhere close and if it delivers what it promises Upon in hand, then it should obstruct potential thieves at least. It weighs about 2 kilos (!) And is best transported in the bicycle basket or in a separate bicycle bag. For longer trips or the use of otherwise very slight (racing) wheels it would be inappropriate, but for our daily short range use and connecting in the garage (as well as wheels come with us, unfortunately away), there is a neat solution and is in value for money front. The security level is indicated by 9, which is on the scale to 15 in neat mediocrity and to protect "Recommended for securing bicycles in good" by the manufacturer is given. The next favorable castle Abus (security level 7; ABUS bicycle lock Steel-O-Chain 880) had, incidentally, very bad reviews, probably because of a flaw in the lock cylinder is subject itself and the next higher lock of Abus (security level 12; ABUS Lock-chain combinations Granite City Chain 1010, 9 mm / 110 cm) also had worse reviews since it probably could conclude only bad / awkward, plus it is probably harder and more suitable for motorcycles. Also this castle has (which probably has to do with the security) no "snap-lock", you must lock with the key in the lock, but goes easy. Especially if you the entire locking mechanism again administered a good deal of silicone spray.
In no event should the way (as we were to learn in the last bike my daughter) use a lock and cable, no matter which brand or thickness of the castle, according to detectives are always cut in seconds with a bolt cutter.
