Couple Pocket Bike Questions.?

I'm buying a Pocket bike this summer and i have several questions

1. is there any electric ones? if so which is best and good for beginner?
2. what kind of maintainance do i need for a gas powered one?
3. where can i get parts for it such as tires, brake, etc? (any stores)
4. is the website below a good place to buy ? http://www.minipocketrockets.com/x7-4-st...
5. what is the different between x7 bullet and 4 strokes?(which is better)
6. What kinda bike is good for a beginner?(looking for one that look similar to racing style ones such as the x7)

any in store dealers that sells pocket bikes? (i live in bay area california)

I have the x7 4 stroke 50cc. I will easily pop a wheelie. Stock it hits 25 in third gear and has a 4 speed transmission. I am 6 foot 4 inches, 154 pounds and can ride it comfortably. All the bolts have locking nuts. I got mine used and learned to ride it just fine.

The x7 4 stroke on the link is a 110cc and will definitely go faster than the x7 bullet. The x7 4 stroke needs an oil change just like you car and you run straight gas while the x7 bullet does not need and oil change but you have to mix the gas with 2 stroke oil before putting it in the tank

I order parts from http://www.sdscooters.com/. They have all the oem parts and upgrade parts.

Tell me if the minipocketrockets site works or not.

If you want it street legal you definetly have to have a 50cc or less engine and might have to do few little modificatons to the bike.

pocket bike's are junk. don't waste your money. save up and buy a real bike.
