It would depend on a few things.
Probably most important is comfort, whats right for one person is all wrong for another. Also depends on what type of bike and what type of riding your doing. I like having my weight quite far back over the rear wheel as its good for jumps and dh but on my road bike I have my weight alot more forward.
karizma is wonderful bike than pulsar 180 the meta and riding position is very good
is a bike mechanical
it could mean the position on the bike. how you sit on a bike can make you more or less aero or sit more upright future back on the saddle etc to open up your lungs or hips to produce more power. the position matter alot to the type of cycling you do if you have a poorly fitted bike your not getting the most out of the bike and could do some stress or harm to your body riding in a poor position
Not a lot. Townies tend to be a bit more utility oriented, and cruisers a bit more blinged out. Both will give you a very upright riding position, and aren't particularly suited for energetic riding.
In German, you say "Fahrrad fahren" to mean riding a bike.
riding a bike can have an advantage over a plane because if you don't want to pay money than a bike is better and that riding a bike gives you cardio.
Tires, suspension, throttle control and your riding position all have important factors in cornering.

The person who is riding the bike dies...if you hit him/her hard enough.
Yes it is. I do like riding my bike. I did like riding my bike
A road bike offers a more preformance-oriented, streamlined hunched over riding position and bike design, while a cruiser bike has the rider more upright and is more set up for comfort than speed.
An air bike is a kind of stationary bike, which makes the whole question moot. For any stationary bike what you want to look for is a decent riding position, a smooth power train with easily adjustable resistance and a reasonably quiet operation.
