A little while back I did a roundup of all the companies offering bicycle insurance. ETA came out the clear winner for being the most generous in their terms and conditions as they cover a lot more scenarios than others. A number of Twitterers and commenters would tend to agree. I also tested out the different companies by calling them up and seeing how long it would take to connect. ETA was the fastest. I always think this is a good sign they actually care about their customer.
I recently noticed on the ETA page that you can save 40% on your bicycle insurance if you have a folding bike. This is a great advantage for folding bike owners so I wanted to spread the tip to you guys in-case you are considering buying bicycle insurance.
Before you do purchase however I strongly recommend calling up the company that you have for your home insurance and seeing if they will also cover your bike. Often this can end up being even cheaper.
Told you this was a quick tip!
