If you like the colour Lime, and can stretch a bit further, this is a brilliant choice

As for getting a BMX in general, just go for it, if you don’t like it, its not going to make you destitute. A good quality full bike for the price of an average joe MTB wheelset. For the record I got my first BMX 18 months ago as a 40th birthday present. I’ve used it every week since whether riding round with the kids or at the local BMX/ pump track, even go to Rush Indoor Skatepark quite a bit. Amazing fun!
