Hey!

Before I go spending money... I would appreciate it if you could give me
your advice on these bikes:

2014 Custom Kink Bmx Bike

wise bmx bike great Xmas gift

BMX Bike with steele bars for tricks <-- IDK if this one is even worth looking at I really don't know.

REDLINE 20" BMX BIKE IN GOOD CONDITION

If you could tell me what is my best choice or even if I want any of these. I'm more into old vintage BMX that I repair... I know nothing about buying a new (second hand) BMX so please help me.
Thank you in advance, because I kinda don't know what I'm doing... sorry.
