I like the way you think. Since this is your first build, keep it simple. You don't need a shift kit. The 80 motor already goes faster than is safe. Don't expect to cruise faster than 35 mph. That's about the upper limit of safety, and reliability.

Be sure and check the laws in your state about motorized bicycles before you waste a lot of time, and money only to find out they won't let you ride it on the street.

I would advise getting a SkyHawk, or Flying Horse motor for a first build. They're less crappy than a lot of the other brands, but not by much. Don't expect much warranty, and you won't be disappointed. Do strip the motor at the very least down to the block. Expect to find a few things needing minor attention like seals, or gears not properly installed.

Expect some teething problems at first. It takes a while to get all the bugs worked out, especially on your first build. After that you'll be able to ride to work everyday and get over 100 mpg doing it.

There's going to be some extra accessories and hardware you'll need in addition to the kit parts. Although you can build a motorized bicycle for as little $350, for a good dependable motorized bicycle expect to spend $600 to $1000 before you're through.

if you need a reliable form of transportation i would not get a china 2 stroke if you cant rebuild it your self. trouble shoot many reasons for many problems. this forum is the right place to look for help but alot of people would be outta work if the china 2 stroke was their mule to and from work. unless you work around the corner that is! 4 stroke kits seem to be a more reliable way to go. their's a lot of good things said about tomos mopeds though and reliable is one thing they are. 187=murder and 502=dui either one= prison time

Man, I agree with everyone.

Start simple. Get a decent bike, put a simple 2 stroke kit on it (without a jack-shaft , or what they call a shift kit). Then after a few months of tinkering and upgrading, you can get a better bike with a shift kit. Or keep that bike the way it is, and get a 4 Japanese 4 stroke.

But, do a search on this forum. Because this topic has been discussed about once a week. I'm sure you'll find all the answers you need in one of these topics.
