Which parts of a bike use friction?
The brakes use friction to stop the bike and the tyres use friction to grip the road.
How is friction good?
Friction is good for two reasons, both are related. 1) Friction allows your car to stay on the road. Bigger tire surface translates to more friction=better handling. Also 2) friction stops your car (brakes). The bigger the contact surface from the tire (the tire touching the road) and the better the braking system (drum brakes or disk brakes), the quicker your car will stop.
What does a dirt bike need to ride on a road?
If it's a public road, that anyone is allowed to use, then the bike has to be road legal (lights, indicators, mufflers, brakes, emissions...) and insured, and the rider will need a driver's license.
Are you allowed to ride your bike on paper rounds?
If the bicycle is road legal(has brakes, lights, reflectors) - sure.
Where do you find friction in brakes of a bicycle brake?
A bicycle has high friction at the brakes, first and foremost. Then at places where the rider holds on to the bike, Grips and pedals. Between tires and road.
Can you use a mountain bike frame as a road bike frame?
Sort of. Most MTBs use 26" wheels while most road bikes use 28" wheels. Although a MTB frame will usually have room for 28" wheels with skinny tires you won't get rim brakes to line up. There are adapters available which lets you mount road-style caliper brakes on a frame intended for canti/V-brakes. or if your MTB frame have disc brake mounting tabs you can get a set of road-size wheels built up with disc brake hubs. Then there is the fork. Most MTBs come with suspension forks, which are pointless energy sappers on a road bike. Simply sticking a road bike fork on there will cause a serious change in geometry, so that's not advisable. Better then to go for a suspension-corrected rigid fork. Next is a question about what crank and what shifters you want to use. Road cranks have higher teeth counts, they do best when paired with road front derailers, which require road shifters to get the correct actuation ratio. Road bikes and MTBs tends to favor different cabling arrangements, which can cause some problems. Bottom line is that it is doable, but fairly pointless. There are plenty of traps you can fall into, and it'll never be a "real" road bike. Better then either to buy a road bike, or simply slap some slicks and a road cassette on your MTB and ride it as it is.
What is the diffrince between a1980s and a 2000s bike?
Not that much actually, if it's a road bike. It'll have a few more gears, be a bit lighter, perhaps more aerodynamic. If it's a MTB it'll have better/lighter suspension, better (disc)brakes and a few more gears. Color scheme and graphics will be different too.
When a bike accelerates down the road what is the reaction to the tires pushing on the road?
drag, because when i ride my exercise bike then jump off, the wheels keep on going for like a half hour, unless you put on the brakes. the correct term is FRICTION.
Where are the brakes on a normal road bike?
In normal use this is not a problem, as the brakesare applied with limited force and ..... Disc brakesare used mainly on mountain bikes ridden off-road.
What is a fixie bike?
Fixie bike are bikes (usually road bike frames) that have a fixed rear sprocket which allows you to pedal forward like normal, but does not allow you to just coast . If you pedal backwards it goes backwards if you pedal slow it will remain slow. The whole point of a fixie is to eliminate brakes shifters to simplify a road bike.
Lightweight bicycles have what type of brakes?
Depends on how far you want to take it, and what kind of bike it is. The most common type of light weight bike is probably a road bike, and they are generally equipped with caliper rim brakes, with single-pivot being the lightest design available. But there are also light weight MTBs, and they generally run disc brakes. A MTB for flat terrain can still have straight-pull brakes(v-brakes), which is a kind of rim brake too. They can still be lighter than disc brakes although braking isn't quite as good.
Why not ride a mountain bike on the road?
A road bike is faster on the road than a mountain bike. That's all
