No because the bike would brake evry time so no
How do kids get to school in France?
By car, bus, walking, bike. The same as in America
Why is it hard to bike up a hill?
Same reason as walking up stairs is hard - you have to overcome gravity.
How many miles bicycling equal a mile walking?
The distance remains the same - whether you ride a bike or walk.
Could a slower moving student achieve greater horsepower than a faster student?
Horsepower is a calculation of work(torque) done over a certain amount of time. If your referring to say, on a bike. The slower kid would need to use a higher gear (more effort required) than the faster kid in a lower gear to equal the same amount of work in the same time. Example would be both pedaling 100yds in the same time, but the faster kid pedaling twice as fast, but half as hard.
What is the importance of the bicycle?
With the price of gas. We are all gonna find out the importance of a bike. Not only transportation. It teaches us balance, hand/foot eye coordination, and complex thinking IE; pedaling, steering, watching, balancing, braking all at the same times.
Does a bicyclist have the same right of way as a pedestrian?
In Georgia, cyclists are considered vehicles and must follow the same laws as motor vehicles. Hence, they must yield the right of way to pedestrians. Cyclists do not have the same right of way as pedestrians.Added: When a bicyclist is WALKING their bike they are considered to be pedestrians. If they are MOUNTED on the bike and riding they have the same ROW as a motor vehicle.
Is walking more exercise or is riding your bike?
Depends on how hard, and for how long you go at it. Everything that gets you equally sweaty and winded for the same length of time will give the same amount of exercise and burn the same amount of calories.
How much more efficient is bicycling than walking?
You can move faster plus you don't have to be working the whole time, you can petal and than coast. A bike is more efficient because instead of using a car you ride somewhere on a bike and you are saving the earth from global warming. On the other hand you might be better off walking just in case you bought the bike from a cheap place. It might fall apart. You never know... You would want a really good bike that can support your weight and that won't crash into anything. Walking may be better for some people if they want the excersise. But it might not be better if you have bad legs or run out of breath quickly.
does cycling a stationary bike give the same benefits of walking?
When it comes to exercise, how hard, and for how long you go at it is more important than what you do. All exercises the gives the same increase in heart rate for the same amount of time will carry the same benefits for endurance. When you look at it muscle-by-muscle, bicycling and walking are different activities, and will engage partly different muscle groups.
Why would riding a bike be more tiring than walking?
Looking at the strict physics and mechanics of it, it shouldn't be. A bicycle is one of the most efficient travelling machines humanity has ever invented. With the ability to coast, and for the saddle to carry some of your body weigh, covering a set distance on a bicycle should consume less energy than doing it walking. The most probable reason why riding a bike feels more tiring is that you're simply not used to it. Bicycle riding uses a slightly different set of muscles than walking, so if you aren't a regular rider, these muscles will tire quickly. And while it's quite easy to avoid riding a bicycle, almost all people walk at least some distance daily. Those muscles almost always get some amount of daily training. Other options include: - a poor riding position. Saddle too low will restrict your leg extension and make the pedaling motion inefficient. - not using it right. Humans - like all engines - have a span of resistance and rate-of-turning where we are as most efficient. For bicycle riding this is generally agreed to be at a cadence - rate-of-turn on the pedals - between 80-100. To many rookie riders this feels unnaturally high, and they insist on grinding it out by pedaling slow-and-hard instead. And tire quickly. If you are using a geared bike, select a gear that lets you pedal at 80-100 rpm. Pedaling fast-and light is the ticket to efficient riding. - a bike in poor condition. Low tire pressure, dragging brakes, rusty chain, stiff bearings etc. All these and more can rob a fair bit of efficiency from a bicycle. - trying to ride in really poor road conditions. A bicycle is a wonderfully efficient travelling machine - as long as it's rideable. When road conditions gets so poor that you're down to a walking pace or even pushing the bike, then you'd be better off without it. - the enjoyment factor gets the best of you. Maybe riding is simply so much fun that you go at it harder, thus making yourself more tired than what walking had made you for the same amount of time.
Are dirt bike wheels the same size?
There are different sizes for dirt bike wheels as there are for regular bike wheels.
