I'm looking to build a motorized bike that can reliably take me about 12-15 miles round trip daily. Speed isn't all that important, as from what I can tell 20-30mph should be achievable.

I started a thread because even after searching through this forum and elsewhere online, I'm still a bit overwhelmed.

I don't have a bike yet- I was thinking I would get the engine first and then get a bike that will be the correct size. What about this kit? http://www.bicycle-engines.com/49cc-4G-T-Belt-Drive-Complete-Gas-Powered-Engine-Kit.html

I'm willing to spend a bit more to avoid junk, but maybe that one I just posted is junk- I don't know. Can I get something decent for less than $400? I saw some rack mounted kits that looked nice but $600 is a bit out of range.

Once I get a kit, how difficult will it be to install? I know that's a vague and subjective question, but if is too far outside my skill level I may be better off just pedaling. What tools will I need? Do I need access to a mechanic shop? I'm not a dumb person, but my mechanical training consisted of my dad telling me which tools to hand him when I was 6 years old.

Sorry for the long post. Here's a cartoon guy falling on his ass
.duh.
 
You will be very happy with that engine kit. it is far from junk, quite actually one of the best recommended, less than $400.00, Chinese 4 stroke kits out there.

For the sake of keeping the overall build simple in end use I recommend using that kit along with a SBP shifter kit, if you can budget the additional cost.

Installation instructions are very well thought out and easy to follow.

There will only be 1 chain so messing with a second sprocket on the left is deleted from the equation. Shifting is easy. Let off the throttle to coast a little yet still allowing the chain to turn, shift the gear then give it throttle again. Never shift under engine power. A high quality rear derailleur is suggested.

Or you can go super simple and keep it a 1 speed.

Most any beach cruiser bicycle or 26" mountain bike without rear suspension will work very well.
You must have excellent brakes though.
A coaster brake equipped beach cruiser is highly recommended against. The coaster brake will not stop you quickly if need be (read crash avoidance).


If you want the easiest to install, least maintenance, no fuss, ride it on 2 hours or less, get a friction drive kit.

Thanks, that was just what I needed. The friction drive definitely looks like the way to go for me.

How can I measure the potential bikes to get a good fit with that kit? I don't have the tools to do any drilling or grinding. I'll probably get a bike from Wal Mart
 
A friction drive kit can be installed on any kind of bike, even ones that have rear suspension. If you do choose to use a bike with rear suspension, you will need to create your own forward engine mounting point as it will have to be part of the rear suspension framework. Also keep in mind that you would not want any part of the engine or drive channel to hit up against the seat.

You can install one on a 12" bike up to a 36" bike even more if you get creative.
You can even install one on a unicycle if you are a daredevil type.
