I am checking if anyone has done this with good results from what I understand most expensive road bike are light because they aren't built like a MTN to withstand lots of weight and such.

I really want a road bike to train with but I'd like to put a motor on it and ride up the west coast.

I'll probably get a touring bike but I thought that I would check on this first.

The wheels are the main problem when motorizing a light road bike. They are more prone to broken spokes.
I would buy an inexpensive mountain bike or beach cruiser for motorizing. Save the road bike for training.

I agree, I've 2 nice road bikes, & also a Juiced Bike's electric CCS and a custom mtn.
gas bike with a Tanaka/G.E.B.E. belt drive. Either one will smoke any road bike made.
Unless you can find 11g spokes for your roady, don't even think about a gas bike.
You could put on an electric kit I suppose, but a purpose built ebike is a better idea.
Anything with more than a 500 watt motor really should have suspension. 033.JPG 002.JPG

I'm currently in the works in putting an engine on a cannondale quick 8. I had to customize the front mounting bracket, the spoke on the wheels are 32s but I ordered a rear 36 and sprocket adapter on eBay. I had to use metal straps for the fuel tank.

Still a work in progress but it's getting there.

not a road bike, but a real light aluminum mountain bike. I have put over 2,400 miles on it and it runs great. I also ride it on trails and in the dirt, never had a problem or crack. I got tired of the tank being in the way and sliding around, so used a lawnmower tank, works perfect.

Actually there's one outfit that specializes in kits for fast electric road bikes, Calibike*
The improperly laced spokes on my Juiced CCS wore out the spoke bores,
The motor still worked but began to butcher spokes on every ride. I bought a Calibike
kit for $250 that came with everything but cutoff brake levers. As luck would have
it, I all i needed to do was plug in the wheel to my existing setup. It was a much
superior wheel with stronger spokes. They also sell very reasonable battery packs,
but i used what I already had. For a bit more money, I could have bought a kit that
turns a road bike into a 40 mph monster, Kits are simple to install & that wheel &
motor has out lived the Juiced CCS,(now a parts bike)
Since then, I purchased a NCM Moscow e- mtn bike that is far better for 1/2 the
price. In spite of the name, it's made in Germany. I guess the idea was to market
it in Russia. Anyway, just because of the name, they haven't sold well here.
They are presently going dirt cheap for $1059, absolutely the most bike you can
buy for the price. I paid $1300, still a bargain. It arrived from LeoncycleUS in
Seattle the day after I ordered it. (I live on the 'other' side of Puget Sound).
This bike will climb a tree.

The Germans are
finicky about engineering & use, be sure to read the manual carefully if you buy.
At this price there's plenty of wiggle room to personalize the bike.( see the EBR
review for spec, etc)

By road bike do you mean a department store imitation or you talking about an actual bicycle shop road bike? A department store road bike will cost around $300 or less. A bicycle shop road bike used by serious cyclist will cost at least $1200 or more. It sorta defeats the purpose of spending that much money for a high quality bike if you're just going to put a motor on it.

On Yahoo Answers Cycling section I often tell questioners that unlike the pedal only world a tick tube heavy steel frame in the motorized bicycle world is a good thing.
