BMX racing doesn't need much equipment.

You need a proper bike and equipment to race, without these things you can't run on the track!

Most clubs offer bikes that you can borrow or hire to try riding and you give it back at the end of the day when you are finished with it.  It will cost a bit more when you borrow a bike, but it is less money that buying your own.

You need to choose the right size bike if you want to enjoy BMX racing and be competitive.

Equipment is important, helmets and gloves are the main things, but it is better to wear protection such as body armour, elbow pads, and knee pads because you don't want to hurt yourself.
