All the information you need to know is on this site.
all you need to do is take the time to read it.

Get this kit --> 4-Stroke, 49CC BIKE ENGINE KIT. UPGRADED DAEMON ENGINE - eBay (item 250709832918 end time Dec-10-10 08:55:16 PST)

Buy some Marine grease with calcium sulfonate active ingredient for the gearbox.

grease every 2-3 weeks and ride until the gearbox goes bunk.

then buy a better gearbox (ie. 4g, stageIII, etc.) when the companies start having them in stock again.

Miami, the Honda is not set up for a twist throttle, at least most of the Hondas you will buy from a small engine site. You'll have to modify the carb throttle to make it work with any of the 49cc bicycle kit throttles. The HuaSheng motors are setup for applications like bike motors. I suggest saving your money and picking one(HuaSheng) from a rep here that has a great warranty policy. I don't like to play favorites, but I am enjoying being taken care of by the guys at That's Dax. They have a one year warranty compared to most others... 6 months. Also the EZM companies has one heck of a gear box and warranty. As far as 2 vs. 4 stroke, there is no better, just different. 2-strokes are performance(lol) HP with quick acceleration and 4-strokes are more torque based with moderate acceleration... this is straight out of the box or what I call the Warranty waiting period, after that do what you want to push the little things... Good Luck!

P.S. Once you buy a HuaSheng kit from $400 to $600 and get a decent warranty, the engines themselves are rarely over $200 by themselves most are $189. So get one with a year policy and when it runs out, buy a new engine with a new one year warranty. Save your old engine for a temp or replacement/parts engine. $200 a year without headaches is much more of longevity plan than expecting one engine to last for years. But then you have people like AZBill who has been putting thousands of miles on his HuaSheng. To each his own, there is no right or wrong.

Miami, I've commuted 80 miles round trip to work on my bike twice in the last year and plan on doing it a lot more come spring and summer.

What you'll get in a kit will get you on the bike - maybe as far as out of the driveway and possibly even down the road a piece. I upgraded most of the parts from my kit.

I went with a heavy duty pair of wheels, one from Husky in the front with a drum brake, one from Bicyclemotors.com for the rear. Both have 12-gauge spokes, and I don't have to bother with a rag-joint holding a sprocket to the spokes.

A throttle can be worked out with the Honda engine. I've rigged up a very capable twist throttle, as well as a remote throttle lever for cold starting. Crack the remote lever open, close the choke and it always starts on the first pull.

Sitting on a stock bicycle seat (mine was a Schwinn) for forty miles at a stretch is a real pain in the Butt. I tried a Cloud 9 saddle, but that still didn't do the job. I went with an expensive Brooks double-spring saddle and it seems to work very well.

Lastly, and most importantly, I worked as a mechanic on Automobiles, Motorcycles, Trucks and Agricultural equipment for about twenty years. I have the proper tools to do whatever job I need, and just barely enough understanding of the mechanical processes involved that I've been able to make a Motored Bicycle that is reliable enough to easily make an 80 mile commute.

A few hard and fast principles and then I'll shut up:

1) Anything that can vibrate loose will. Use Blue Locktite on everything that isn't fastened with a locking nut. I use the Nylock nuts.

And use Blue Locktite only on Clean threads. Oil, grease, or dirt on threads and locktite is useless. I clean threads on bolts and in bores with Laquer thinner. Use Q-tips for the bores. It'll save you a ton of headaches later.

2) Everything you do on a Motorized Bicycle will take twice as much time, effort and money than you think it will. Get used to it.

3) Get an accurate inch-pound torque wrench. Learn the torque values for the various metric sized fasteners you'll be using and torque them properly.

4) Go over every fastener on the bike after your first ride and fix what needs fixing correctly. Be prepared to do everything two, three, or even four times on your first build.

5) Be patient. Nothing screws up a project like Get-Done-Itis. The bits and pieces you'll be working on don't give a rat's how impatient you get.

To get an in-depth explanation of the relationship between personality and mechanical principles read Zen and the Art of Motorcycle Maintenance. It'll show you how to get the correct mind set for what you are going to try.

Good Luck

hmm....thats 19.99 more then i paid for my car, a 2000 hyundai, which i've driven for 2 years,25,000 miles.

I typed F/S into google and got this :



This seems like a good deal, it kinda looks like all of the others, but this one costs $3,000. I wonder what's so good about this frameset? The bike built up is $8,000....do you think it's close to the Mongoose in anyway? It's only a $7,500 difference, give or take a few bucks!

Now about the engine......
