- Use a lock the is commensurate with the value of your bike. They suggest a lock that is worth 10-20% of the bikes worth. That would mean $200-300 on the low end for either of my bikes and I can't imagine the weight of such an expensive lock. The locks I use are valued around $60 and I've purchased one each for home and work so I don't have to carry it with me.
- They also suggest using two locks at once--One U-Lock and one chain. Each requires a different tool set to defeat which reduces the chance the thief will be equipped for the challenge. London must be a tough city to ride a bike in.
- Use the lock properly. Leave as little slack as possible to take away leverage for the thief. Also, don't leave padlocks in a position where they are resting on the ground. This makes them vulnerable to a sledge hammer. Also, lock to an object a thief can't just lift the bike and lock off of like a bollard. Tory leader David Cameron just had the second bike this year stolen because of a miscue like that.
- High value bikes are a target. Don't park in the same place every day and park near someone with a better bike if possible.
- Uglify your bike. Even if the thief sees through the camouflage it lowers the resale on the ride making it a less tempting target in the first place.
- Invest in a folding bike that you can take with you into the office.
