It's much more about technique than it is about speed. With the right technique (bunnyhopping) you can jump a BMX at crawling speed, on flat ground. After that, more speed + bigger ramps = longer/higher jumps.
It is about 155 give or take a few, it varies bike from bike
If you were going to slow into a jump you would just have to jump higher in the take off. You see when you jump, the speed you gather helps your take off and makes the jump easier. With out speed, you would have to use much more power to get your self in to the air at the right height. The other options are to either fall or( if you're only practicing) stop and start over with more speed. Most of the time if you don't have enough speed you would just keep pushing until you got the right amount of speed. Depending what jump you're doing and how consistant you are at it you need different speeds.
There are two ways you can do this. In both cases, you sit on the bike as when driving it normally. First, take the bike to a steep hill. Switch it on, put it in fourth gear, pull the clutch, but put the choke on first. Let it roll down the hill until you reach a speed of perhaps 20 to 30 mph. Then release the clutch as you give the bike some gas. If the battery is good the bike will start immediately. The second way is to have three or four strong friends push the bike on a level road until it gets up to as much speed as they can muster, then release the clutch. The bike should start. Never attempt to tow the bike to jump it using another bike, a car or a truck.
It would take 15 hours to bike 225 miles at a speed of 15 mph.
That depends on your speed.
On the Acro Bike, press B and the arrow on the D-Pad you want to move in. It may take some practice to master.
It really all depends on the speed you are going.
IT DEPENDS ON WHAT POCKET BIKE DO U HAVE
Three hours (30/10 = 3).
with average speed, 8-12 minutes approximately
The time it takes to bike 2 miles depends on your speed. On average, it takes about 10-15 minutes to bike 2 miles at a moderate pace.
about 2 hours
