Get a KTM
Regular gas should be fine
You should use 93 Octane in your bike.
it really depends what kind of mountain biking you want to do. if you are doing it seriously or just for a bit of fun. you should go to a bike shop and tell them what you're going to do and they should recommend bikes that would suit you. hope it helps :)
For your Peloton bike, you should use cycling shoes with cleats that are compatible with the bike's pedals. Look for 3-bolt cleats, such as SPD-SL or Look Delta, for optimal performance and safety.
One suited to your height, weight, intended usage and your wallet.
Simply register the acro bike on select then when you first enter head north and should see some kind of white bridge you should notice there are many gaps in the bridge do a sideways bike jump to go past the gaps.
You should be able to, but I recommend going to a bike shop and using the bike version rather than the car version, or you may just blow the tube with that kind of volume of air.
a bike that is small
You should get a bike license if you ride a bike and don't want a citation.
Look on bikesdirect.com, they have really good deals on bikes.
What kind of an idiot are you? That seriously depends on what kind of freaking bike you have, STUPID!
