"Iiketoscooter", you need to completely gut your folding mech, take off the plate on the front, and get more bolts and normal sized washers. Then you'd be set.
No, just regular bearings from skateboards and scooter wheels, I don't skate anymore, so they don't mean anything to me. BTW, I'm getting a longer bolt today for the back peg, because its a little small.
It looks alright to me, but you might wanna take off those crappy plastic handle bar holders - it can make annoying noises.
Unless of course you like it there, lol.
Max pudans, your picture there ( I think its called a signature) looks cool but it actually looks like a guy from DogTown skateboarders. Forgot his name.
