    Now, I'm looking at building my second MB.

    My first one is well... dodgy to say the least and i am expecting something to blow up any day now. (had it about 9 months)

    I currently have a 48CC 2 Stroke.

    I am not sure what brand specifically, i bought it from Motowhizza on ebay.

    Having this bike has taught me alot, ie. dont put a engine on a bike that you bought for a 6 pack of beer.

    So now im looking at doing it properly.

    I stumbled upon zbox in another thread here and they got 2 engines, the 2 stroke and 4 stroke.

    Now, my mechanical knowledge was near to 0 before i started on this endevour, i know know the basic ins and outs of my dear little 2 stroke.

    I have no idea on the differences between 2 and 4 stroke though beyond the fact that your oil is seperate in a 4 stroke, like a car, and it will run quiter.

    so yeah, these the 2 engines


    Now, if we forget the $175 price difference, is there any reason not to get the 4 stroke?

    Is one faster then the other? My aim is not to go super fast, but 50kmh top speed on the flat would be nice.

    So, thats enough on engines. Onto the bike, my current one is slightly terifying, old school brakes, the center mounted ones, riding in the wet i have to use engine braking every time i want to slowdown/stop.

    I see lots of Schwinn around here, so started investigating that.


    This one looks like it would be the go. Main apeal for the 'cruiser' style bike is the large frame area and single gear, more room to work, 1 less thing to break.

    Also, it looks like the engines just fit on them perfectly, without the need to build some kind of special mounting setup which is needed with many fatter framed bikes.

    Only thing that makes me hesitate about the Schwinn is the lack of front shocks. It is something that i do no have on my current MB and something that i would really like to have. If anyone can recommend a decent bike with front shocks for under 500 that is relatively easy to attach a engine to, i would be in your debt.

    So yeah, thats my wall of text :D

    well - just a few things to mention here -- a little food for thought for you

    two strokes
    more noise
    usually faster
    mix the gas with oil
    a little smoke

    four stroke
    way less noise
    just seem to have a more (cool sound) just one mountainmans opinion
    more low end torque
    no need to mix gas with oil

    maybe a lot of this boils down to MB profile

    I had a Yamaha Twin Jet 100cc once
    that thing was faster than heck
    made one wild loud noise
    blew smoke all over the place
    what a fast sight to be seen
    noticed by all

    then I went to a Honda 4-stroke 90cc
    a very sweet riding little motor bike
    speed was alright
    no smoke, no noise, no problems
    no one seemed to notice it go by

    even though slower and a little heavier -- I perfer 4-strokes...

    ride that thing
