bmx biking by: tony bouchard
Question:
Do lighter bmx bikes have more or less grip than hevy bmx bikes?
Does the waight of the bike have anything to do with how mutch grip it gets?
Do smaller sprockets make a difference in how fast the bike goes?
Does the size of the wheel matter?

Research:The waight of the bike does not matter unless you are doing tricks on it then you would rather it be lighter so its not so hard to get off the ground. and the waight of the bike does not have anything to do with how mutch grip you get its all in what kind of tires you have. the size of the sprocket does make a diffrents becouse the smaller the sprocket is the faster the bike goes in less time. and the bigger the sprocket is the faster the bike goes but it takes more time but you can go mutch faster. thats what bmx racers use. this is an pic of a small sprocket. and the bigger pic is the bigger sprocket.
http://www.gtbicycles.com/usa/eng/, i use power to pedel the bike to make it go faster or when i do a wheelie. and there is force on me and the bike when i land on the ground from a jump or when i do a bunny hop. and the is friction on everything on the bike if there is not barings to help the bike ride smooth and it will be hard to ride it becouse the wheels will start to slow down becouse there is friction.
