Buy a BMX frameset and put your own selection of components on it.Switch parts out for rarer, more expensive parts, have it repainted.
Depends on what's already on there, what's available, and how much clearance the bike has at the fork and frame.
Means that it still has all the parts and only those parts that the manufacturer put on there. Nothing has been added or replaced.
It´s the Stem, it holds the bars and match with the frame with the help of a headset.
Where ever he put it last.
i have no clue, but this is for school, and i need to find something to put REALLY quickly.
duck tape
put my mum on the seat and grind
Yes you can.... you can put any hub, spoke, and rim combinations together...maybe a few ecceptions but you can deffinetly do that... just bring the parts to your local shop and have them lace it.
Pull your front brake or put your foot in the backk of the tire.
change out the hub
If you have a flip-flop BMX hub, you can put a 14T on the smaller diameter side of the hub. If you have a cassette hub, you can get as small as 11T.
