Have recently bought a BJCM for grandparents to use as they can't get bugaboo in car and on their first outing with it today it seems to be folding when it shouldn't.
Basically, when it is up, as soon as you out any pressure on the handle bar i.e to go up a kerb, it starts to fold in half even with safety straps on.
I used it a couple of weeks ago and didn't have any trouble so cannot understand what can have changed. The instructions imply that when you put it up it should lock into place, but this doesn't seem to be happening and I can't see what it is that should be 'locking'.
Any ideas?
