The kit that I have will not work on the first bike that is pictured. It should, however, work on any of the 3 bikes in the second picture. In order to motorize the bike in the first pic, you would need to get an engine setup over the rear wheel.
What do you want for the red road bike?.. also..The engine will work best on the Green bike. I can not tell from the pic what kind of brakes it has. It will also work on the blue road bike except the bars will be too thick for the throttle. So..you will either have to change out the bars or come up with a lever or thumb type throttle setup. Thanks..
