A bicycle helmet can be anything from USD 30 to USD 200. Get the one that fits your head, and looks nice enough so that you use it.

I have a mini bike electric and i got it for $250. If i were you i would get a electric and get a gas which cost around $500 for the bike, helmet, and the gear
A good race mountain bike would cost you about $6,000 to $10,000
depending on which model, a new eastern bmx bike would cost anywhere between 400 to 600 for a good bike. check out danscomp.com this is where i get everything for my bikes
There's really no way of telling since I don't know what you think of as a good bike, and if you're asking about the cost for the factory, the cost for a single guy knocking something together in his garage, or the cost for a chain of stores.
it will cost £500,000 because i have bought one;)
Safety! The helmet will protect your head in case you fall off or get thrown off the horse, much like wearing a helmet on a bike or motorcycle. You should always wear a helmet.
