My Bugaboo Bee (bought second hand on eBay 5 months ago) has just started not folding properly. The automatic mechanism that makes it fold itself when you pull up those slidey things on the handle isn't working, so I have to physically push it downwards to make it fold and it is very stiff. It just happened suddenly overnight - was working one day and not the next.
Anyone know what the issue might be and what I can do to sort it out?
