I've recently bought a Viva Pista 3 single speed bicycle, after getting my previous bike stolen. It's a really nice ride and very good for road rides. It's my pride and joy.
However, it's not something I want to lock up outside a shop; it's probably going to get stolen if I leave it out of my sight. I have a pretty decent lock (Kryptonite D-lock with cable flex) and the bicycle is properly insured. However, I still wouldn't like to lose it.
Really, what I want is a very cheap, mechanically simple bike under £100/$150. Ideally it'd be single speed, have MTB tires and have a pretty upright posture. Basically, a bike that if it disappeared would be cheap to replace and I have no emotional attachment to.
Does anyone have any recommendations?
