I understand 750Watts and/or 20mph speed without pedaling is the limit in most U.S. but, if I have a kit like that, is it worth it? Is the quality very bad? Who are trusted/reliable vendors of such kits? If I am guaranteed that speed and reasonable distance to get to school and back 20+20mi should i do it? Gas is $3.49 here, even a 250cc bike is like, expensive :(

Worked on these for a few years in different shops.
Have seen some very sketchy products marketed from china that offgas chemicals
I would only recommend http://www.bionx.ca/en/ then http://crystalyte.com/
The Bionx kit is now built into a bike marketed through Trek,

They will do what is advertised but the batteries will not last long. I would honestly rather point you at a gas motor kit for the mileage your planning. It will be cheaper in the long run

know any Electric Bicycle kits from ebay can go at least 20mph?

sellers are giving me strange details like 200rpm or 50kpm and I'm pretty sure the rpm was counted with out weight. Also what do you think would be the best battery?
Answer
Your speed on level ground with no pedaling will vary. If you have more than 750 watts power or go over 20mph then the bike is not an electric assist bicycle, but rather legally considered a motorcycle.

The best battery is Lithium Iron Phosphate, but those will cost as much as the whole bike. The standard ebike comes with a sealed lead acid battery.

Is about $500 shipped to a store you choose for pickup. That is usually less exensive than doing a conversion yourself. The price for this bike has gone up a lot. I paid $375 for it 2 years ago.
