Scott are you talkiing about the scooters all the lads are into now. I have gone through the whole process with Brooke. Where now I'm buying him wheels for £20 each and bearings 8 for £30 . T bars £55 , grips £ 20 . The scooter he has is a razor pro but he has his eyes on a new one which is £150 . Trust me it's a serious rip off , but don't buy cheap stuff it will last a few weeks.
I do remember my parents telling me I was mad the money I spent as a lad on the best wheels and trucks for my skateboard, how right they were

I've prob not helped you much, but what I will say is don't buy cheap, budget £150 for scooter, decent wheels, bearings and bars .
