Hi!

Hey guys!

I managed to get a Trek 800 for very cheap. I think I will mount my motor to that. It looks like it is already somewhat modified, in that it has no gears on the back wheel. It only has three gears on the front. I will look for a vendor and ask them my questions. I was at first looking at getting a rear friction drive, as I read that they don't break down as easily, but then I read that they work better with smooth wheels, and this one is a mountain bike. So I was thinking a 2 stroke. I still am having trouble finding if I should get a certain CC, as when I look that up, it seems the thread always changes before I find my answer!

with two strokes, you only have two size choices-- 49cc and 66cc (which will often be listed as "80cc"). the external dimensions between the two are pretty danged close (maybe even identical), so I personally went with a 66cc. It was not much more expensive.

A big part of why rear-mount friction drives are reliable is that they are (usually) made with 4-stroke engines which are more reliable than the 2-stroke engines on the motor-biking market. You still have the option of rear chain drive and rear belt drive if you want to keep your knobby mountain bike tires

Hey... I have a question though. Normally, one would mount a rack on the back to carry stuff on the bike? But if I get a rear engine mount, I really can't do that. Have you guys any clever ways to still carry stuff on a bike with a rear engine mount?

you could get a front basket for carrying things. or panniers (saddle bags). There are frame bags, too

or trailer....or lots of pockets.

Seriously, I use a Bob type trailer that I have carried a welder in. Not recommended, but it is possible. Back packs are handy for smaller stuff.
