Welcome in Ritchie
yup the small BMX can be fun ~ a bit quicker then a MTB and they make a great ride
you have a cheaper end bmx, but with a couple of changes you can make it a sweet ride
First I would change the Stem (holds the handle bars) to some thing like a SR Stem (stronger and used by loads of bikes )
after that it might be a brake change depending on how you feel about the one's on there at the moment !
Quiet a few guys are into there Dubs and BMX seems to go hand in hand with them (could be a age thing or just a cool thing
Get some more pictures up of the bmx and let us know what you think about it and what you want to get out of it
