    I'll throw my 2 cents in here and say if you have 3rd world roads like the roads in L.A. then you better buy a heavy duty bike cause those roads will destroy a cheap bike. High speeds and the added weight of all the stuff bolted to it will stress a cheap bike to it's limit. You will can away with a lot though if the roads are autobahn smooth. The roads condition that you travel on will determine how long your bike lasts or doesn't last. Every rut, bump, crack, and pothole is greatly amplified as your speed goes up. Get a bike with wide wide tires and at least front suspension if you can afford it.

    Im 6'5" 270lbs and I am getting 35mph on my set up and the engine isnt done breaking in yet. I have the 44t sprocket. Im interested in your post because Im trying the same thing, but for the purpose of crossing the intercoastal waterway bridge without pushing it up the incline. lol.
    I have a 26" schwinn cruiser from Target for $130 with the 44t sprocket. I expect (as I put in my own post) that doing the free mods will give me the boost needed.
    In my town cruising round faster than 20mph in town is a recipe for disaster, I give everything the right of way and engine brake as I approach lights and intersections. So far no one has out right cut me off but......
    The problem is visibility, you have to give people a chance to see you! I only get up to faster speeds on the long straight aways like heading out to the beach or back roads with minimal traffic.
    Brakes, Helmet (brain bowl), visibility vest, lights, ya know all the stuff they talk about for motorcycles.

    No Oops required, I am glad a couple other riders have chimed in and echoed my concerns for this new motorized bicycle builder. I had the feeling for a while he was thinking I am just some kind of nay-sayer, it's good for others with experience to chime in and form a consensus, perhaps he is more likely now to heed our warnings and not get hurt...

    Have you been to florida? He probably won't listen. And then it will be 'you guys said to do it' like some school yard idiot. I built my bike with a Walmart Schwinn. I would do it again. But NO WAY would I try to make it geared for 45mph. That's just crazy. And having it geared like that is going to kill it going up a hill. Right?

    I live in Florida and the only hills I have are intercoastal waterway bridges and only one bridge has a steep incline that I feel prevents the bike from making it. My thought is if I am a half mile back and I can gun it to 40 mph will there be enough momentum for it to make it the rest of the way up? http://bridgemonitoring.com/bridges/SR520/SR520.htm
    Dont know if you can make it out but one side has a long gentle climb and the other side is quite steep, well, steep for a flatlander! lol.

    From all the responses I read, it's become clear that if I don't need the torque of the 66cc engine, I might better go with the 49cc engine?

    I only wanted the 66cc engine to get better top speed, because it has better torque, I could equip it with a smaller rear sprocket.

    However some users said that the 66cc vibrates significantly more, is this true?

    Also, some users said the 49cc is better for top end speed; again, is this true?

    Now,if the speed is limited to 20MPH, 30MPH tops, then I believe a 49cc should do perfectly fine for me, and may even be preferable.
    In fact, a 33cc engine might even be better.
    I'm only 170LBS, and live in FL, where the roads are pretty flat.

    With the 49cc there's less chance of torquing the frame, or vibrating it loose.
    It also (theoretically) will have better gas mileage than the 66cc, be it only very minimal (perhaps a few MPG's on a hundred).

    Going smaller on the engine, and rear sprocket, makes things easier for the bike. I might even get a beach cruiser, and install regular V-brakes.
    If people at 200+LBS can cruise beach cruisers, I'm 170LBS, with an engine I'll be about the same weight, so I think I finally made up my mind on the engine and sprocket!

    Now it's just the bike, and I'm doubting between the 29 or the 32 in wheeled beach cruiser bikes.

    I'm Going for wallyworld after all... This is only a small project for fun, and I won't even be riding the bicycle that much. More than likely I'll give it away to a friend soon, who has no drivers license, and is very short on money.
    So the 29 in bike it will be (as the 32in bike is still good for me, but too large for him)!

    I'm going to do some readup on the Genesis Onyx 29, before purchase!

    Hey whats with the weight comment....Im "fluffy"! lol I got the 66cc since I am so fluffy I thought Id need the power to haul me around. I dont notice any excessive vibration but then again, it takes more to move me.

    No offense meant with the weight mate! ;-)

    I'm just trying to compare, to see the strength of the frame, and performance of the engine in my situation to whatever info I got from other users/riders.

    Keeping your latest posts in mind (about possibly passing off the bike to a friend) I think a good way for you to go is buy the WM bike and a motor kit and build up a stock configuration first. Whether it be 48cc (preferred in States where 50cc Max is written into the law) or 66cc isn't a huge issue. Since you were initially inclined to push the limits of a 2-stroke kit I would probably suggest you go 66cc (if the law allows) so you can get an idea what power is available from the largest motor. After you have completed your first build and rode enough to break in the motor you will have gone through the learning curve we all go through on our first build, THEN you can access the whole situation from a point of experience. If you decide to tackle a second build you will have more experience with a motorized bicycle and be better able to logically access and achieve your initial goals.... and when you pass off your first build to your friend you will have someone to ride with...brnot

    I like your logic, how you think; and can agree to that!
