We're thinking of getting one for DS for his 2nd birthday next month, mainly so he can use it this summer (if we have one this year). Otherwise he'd have to wait til Xmas then probably wouldn't really use it until he's 3.
Is 2 a bit young? He's very tall so not worried about size, just mobility. He didn't even walk til he was 17 months!
I'm thinking about getting the Islabike one...
