The front base unit will not lock down together with the rear wheel portion. Something seems to be holding the front unit up and will not allow the latch to engage. I’ve looked real close at both ends but I do not see anything interfering with each piece. Scooter is about 4 years old and I never had any previous problems.
I’m guessing it’s just not hooking on because you’re not going in straight. You need to have the 2 pieces lined up almost perfectly. Most of the time I myself have a little trouble connecting the rear and the front together because I didn’t have them lined up properly when trying to re-connect.
