What are the components of a bicycle system?

The main parts of a bicycle are wheels, frame, seat, handle bars, and components. We also could consider the helmet as a key safety issue. Wheels give the fundamental purpose to the bicycle; that is why we call it a “bi” (meaning two) and “cycle” (meaning turning).

### How can I tell what speed my bike is?

Multiply the front gear number by the rear gear number to get the number of speeds. For example, if you have two front gears and five back gears, you have a 10-speed bike. If you have one front gear and three back gears, you have a 3-speed bike.

Can I convert my 8 speed bike to 10-speed?

Answer: No you don’t need a new hub. However, you will probably need to put a small (~1mm) spacer at the back of the cassette, otherwise you won’t be able to tighten the whole cassette down. The 10-speed freehub bodies have taller splines, so they avoid this problem (but don’t work with 8- or 9-speed cassettes).

## Is 7 speeds enough on a bike?

### Is 8 speed bike enough?

8 speed rear cassette is good enough- Providing you get the range correct for your legs. But that is easier to do with 10 speed- I ride 8 speed(24) and 10speed (20) and have to admit that the 10 speed is easier to find the right cog. Even 7 speed is more than enough.

What is the input energy of a bicycle?

Appliance Input Energy Output Energy
hair dryer electrical heat and moving energy
car moving chemical from petrol moving energy and heat
riding a bicycle chemical from food moving energy and heat

## Are heavier bikes harder to ride?

Not harder, just different. Heavier bikes take a little more focus to not tip over at extremely slow speeds, but they also begin to self-balance at slower speeds than light bikes do.

Is gear 1 high or low on a bike?

Bikes generally have 1, 3, 18, 21, 24, or 27 speeds. (10- and 15-speeds are obsolete and you don’t see them on new bikes anymore.) Lower numbers are the low gears, and higher numbers are the high gears. First gear is a low gear.

## What type of system is a bike?

Yes we think of a bicycle as a system because a bicycle is made of many subsystems, and each subsystem has its own job. For example, brakes slow down the bike and the wheels move the bike.

What does a 7 speed bike mean?

What is a 7-speed Bike? On a 7-speed bike, the lower gears make it easier to pedal and the higher gears allow for better movement going downhill. Compared to a 3-speed bike, a 7-speed is preferable for a rider who travels on varying terrain.

### How much does bike weight affect speed?

For the average-strength rider on the 2016 Transcontinental (TCR) route, decreasing the total weight by 5 kg would make the average speed increase by just 0.41 km/h and the total cycling time would be reduced by 3 hours 23 minutes (so the finshing time could be about 6.5 hours earlier).

How does a bike system work?

Bicycles turn energy created by our bodies into kinetic energy. A bicycle can convert up to 90 percent of a person’s energy and movement into kinetic energy. This energy is then used to move the bike. The rider’s balance and momentum help keep the bike stable while traveling along a path.

## What does 8 speed mean on a bike?

In a Hub Gear system, the gears are enclosed within the bicycle’s rear hub. When “3 Speed” or “8 Speed” is mentioned in relation to a hub gear, it means that the hub has 3 (or 8) distinct gear ratios.

Real racing bikes are fast because they use supple high-performance tires. Their frames flex just the right amount for a powerful rider. Racing bikes are fast because the rider has little wind resistance thanks to the low riding position, narrow handlebars, and tight-fitting clothing.

### What is the output of a bicycle?
