No. More people run on the bike path by my house then ride their bike on it.
because you put more weight on your bike, therefore making it more difficult to ride.
No, it is illegal to ride a dirt bike on the street but you can ride it on a trail or dirt bike track.
A bike is a bike is a bike, can you ride one you can ride them all - after a fashion. MTBs in particular are rather easy to handle as the riding position is fairly upright. In terms of difficulties of merely riding down the road I'd say that a road bike for the same given size is more difficult to ride as it will have the rider more stretched out and hunched over, but it's not like that is hugely challenging either. The hardest bikes to ride are probably the recumbents, particularly the ones with waist steering. Those tends to take some getting used to.
Get a bike and ride it
Scooter are safer, but bikes are more fun
You ride a bike because it has to be balanced by the operator.
It depends on how fast you can ride a bike!
i keep the bike on tand and ride on it , then handle is no bar
because the traction on the mountain bike tires have more of a grip to be able to ride on a mountain when a road isn´t that hard to ride on and to need more traction.
