Good first bike?

Id say go for it, my first BMX was a used Wethepeople justice 2011 (maybe 2010). I paid £100 for it, I loved it. It hadn’t been maintained the best but it still worked perfectly fine, I just cleaned it and fixed a few lil things. prolly need more pics but from the one you’ve uploaded, it looks like itll be good! Maybe might need some upgrades in the future and also to make it suited to your riding style and height ect..
