Could someone explain how..........?

Question

a 18 speed gear system works on a bike? I haven't been on a bike for years and forgot how it works.

the bike i've got has a lever on each hamd grip the one on the left is numbered up to 3 and on the other grip it is numbered up to 7, i'm not sure how to shift up the gears.

Answer 1

You have 21 gears, not 18 (3 front x 7 rear = 21). The left shifter operates the front gears, and the right one does the rear cogs.

RIGHT = REAR

Here's the general principle of it: the bigger the front ring you use, the harder it is to pedal but your top speed will be higher.

The reverse is true for the back, as the bigger the cog you are in the easier it will be to pedal. Do not cross gears (using the small ring in front with the small cogs in back, or the big ring with the larger cogs) or you will stress your chain and it will break.

If that's confusing, just think of it this way: the farther your chain is from the center of the bike, the harder your pedaling will be. Put the front shifter in "2" to keep it in the middle ring and ONLY use the right (rear) shifter for a while. Pay attention to how each shift affects your pedaling, and when you are comfortable with that go ahead and start using the front (left) shifter in the same way.

Answer 2

Usually a bike like this has 3 large sprokets at the pedal and 6 in the rear wheel. When you change gears you move the sproket from one of these to another thus creating another gear level. If you go from a large gear to a smaller one it gets easier to pedal but you do not go as far on each revolution of the pedal. To achieve maximum speed you would be in the largest sprokets on both sets of gears and vice versa going up a steep hill the smallest sprokets would give you the easiest pedal but you would barely crawl up the hill. Have fun switching gears and hers hoping your derailer doesn't move the chain off of any sproket, cause that can be pretty greasy.

Answer 3

If you have 1 labeled "3" and 1 labeled "7", then you have 21 gears. The shifter on the left is for the front gears, the larger the sprocket, the faster you will go. The right shifter controls the back gears, the smaller the sprocket, the faster you will go. So, if you're in the largest front gear and the smallest back gear, that's your highest gear ratio, used for riding downhill or with a tailwind. If you're in the small gear in front and the largest in back, that's your lowest gear, used mostly for going up steep hills.

Answer 4

see in the 1st gear the cycle becomes simple to ride because the chain is loosened and gradually it becomes tough and in the 18th gear it becomes toughest and you have to pull hard but after sometime your bike becomes zoom and it becomes a cool ride !!!!!!!!

Answer 5

Push or pull the levers and pedal
