About $40 - and there were no BMX or mountain bikes.
You could check at a local bike store. There are BMX bikes, mountain bikes, road bikes. The main differences are the types of tires, suspension, and brakes.
yes there the best bmx and there alright mountain bikes. great hybrids and light road bikes
BMX bikes were invented in 1974. It became official when George E Esser founded the NBL. There is no main manufacturer of BMX bikes but there are many different ones.
A racing bike, a mountain bike and a BMX bike.
yes they do
There's hundreds of different kinds of bmx bikes there's Eastern bikes, Fit bikes,free agent bikes, diamondback bikes, even some bmxers use pro mongoose bikes.
BMX bikes weren't around in the 60s.
I have no idea what you mean by a "bmx bikes device".
That's a pretty muddled question, you might as well ask what makes shoes different from other shoes. BMX bikes can be built for different uses, there are race bikes that are light and have brakes, there are vert/trick bikes that don't have brakes and can take a lot of abuse.
in my opinion i rate haro bmx bikes,gt bmx bikes and redline bmx bikes as the top 3 bmx bike brands
