Pretty much all bikes qualify as chain and sprocket gear systems, and the ones with internal gears also have planetary gears inside their hubs. There are also two systems available that puts planetary gears in the crank assembly. Well, if it has an internally geared hub it has a more or less complicated set of planetary gears(depending on the no of gears). If it has experna gears then it has front set of sprockets and a rear set of sprockets. By running the chain over these sprockets in different combinations you get different ratios that can be used depending on how hard the rider wants to pedal.
Brake levers and gear levers. The pedals are also a sort of lever.
I have no idea what you mean by "gear bike", so the question can't be answered.
Top Gear Hyper Bike happened in 2000.
Depends more on what type of gears that you have than it does on the size of the wheels. If the gear levers are the same type as on a bigger bike the 24 inch bike will shift just the same way.
Yes
A brake shows the car/bike down until it comes to a hult/stop. A gear changes the speed the engine works at depending on what type of road you are driving on and the speed limits. If you are asking about a bike then the gear's change the speed at which you pedal at, gear 7 on a bike makes you pedal slower but you have to push harder down on the pedals, however gear 1 on a bike makes you have to pedal faster and more genitally on the pedals, - both gears really work your muscles... so if you have a bike with gears up to 7 stay on 3 or 4! Gear box = what you use to change the gears on a car. Handle bar = what you use to change the gears on a bike.
no dirt bike gear is just a helmet and jacket, but paintball gear is a helmet a paintball gun and padding
Top Gear Hyper Bike was created on 2000-03-07.
Pick a gear that gives you the right ratio, then go for it. No difference than from a single-speed bike.
being in top gear means you cant shift no more and means your going fast as your bike will allow and by bottom gear you mean low gear which means your in lowest gear possible.
dirt bike clothing: shirt, pants, helmet and other protective gear
it means...that all the gear of bike can put in clockwiswe direction...i.e back side
