1) Bicycle:> types:

> Platform pedals should provide a good grip with the bottom of your shoes and allow easy re-positioning.
> Tires should allow you to ride well in the tracks, preferbaly a larger tire in the front than the back.
> proper padding: Place pads on your top tube, stem and handlebar crssbar for protection should a crash occur.
> brakes: It is important to ensure that your brakes are in good functioning condition before you start a race to reduce the risk of any unwanted accidents.
> gears: It should be chosen with reference to your riding style and race course. A good combination that is suitable for many is a 44-tooth sprocket with a 16-tooth freewheel. By increasing the number of teeth in the freewheel, the bike will be easier to pedal. However, for the sprocket, the decrease in the number of teeths will allow easier pedalling. Therefore, people usually use a 2 - 1/2 teeth change for the gears, whereby they may choose 42-15, and 46-17 etc.
