Hi Lula, Thanks for getting back to me - frustrating !! Why do faults always occur just after the warranty expires...? Yes - it is the same side of the buggy - the right hand side - with a white-only lever. The other annoying thing is that it seemed to happen when I was looking at another fault on the same buggy. My handle bar lock on that side had stopped working, so the handle only supported on the left side. I'd kind of ignored it as it didn't affect me using it, but yesterday I decided to have a look at the mechanism - moving the handle up and down a few times, when bingo - I couldn't collapse it at all. I've been on the internet looking for solutions - and have also found the pit stop which you mention - but they don't at first glance seem to fix collapsing mechanism faults for the Bee. Arghhh. Since my little girl is 2.5, I am almost buggy free - it's so annoying that it has happened now! Don't really want to spend loads more money on buggies now. Let me know if Pit Stop sound positive. I'm sure if you can get into the aluminium bit, which seems to be riveted together, then it will be a simple wire or something. Thanks again,
