depends on how fast you peddle
That's 12 MPH, or just shy of 20 KMH. There's no way of telling if this is "good " or "bad" w/o knowing the riding conditions. A road race on a flattish course will be at about double that speed.
About 20 minutes.
21.75 miles per hour
40 mph
when you sit on the bike, you should be able to touch the ground with your toes.
It takes very little skill or effort to change a bike tire. Anyone who rides a bike should be able to do it.
Yeah you should be able to,
Should be able to do over 100mph
You don't have to remove any bike light, but anything that can be screwed on can also be screwed off. If you have to leave your bike unattended you might want to think about that. Apart from that a few minutes of browsing, either an online retailer or a bicycle store should be able to set you up with a screw-on bicycle light.
It depends on where you live. You should be able to ride all in the US
If you can find a large enough bike shop, they should carry pocket bikes or at least be able to direct you to a location that does if they do not.
than you should be able to buy it, but when i tried it didnt work?
There's no fixed answer to that, as it depends on type of bike, how hard the rider is trying and how fit (s)he is. I could do it in 20 minutes or so on my commuter bike, but I'm not 300 lbs. Around 30 minutes should be doable.
You should be able to move the chain up and down aprox 1/2" with your fingers.
It helps, you should at least be able to tip toe and touch the ground.
Find the serial number on the engine, call up a motorsports place and they should be able to tell you what year the bike was made.
