Isla bikes are fantastic things, very nicely designed and made too. However, they are very desirable to the light fingered fraternity, partly due to the fact there is a big demand, and second hand Isla's are not much cheaper than new ones. As for the rough handling that you'd expect from a child, they are built to take knocks, cosmetically they may end up a bit ropey looking, but with a bit of TLC, that's not a big problem. Just try to make sure she doesn't leave it lying around, then walk off somewhere without it.
