felt bike info needed

[hotrodlincoln]

Hi, I have been looking at all the felt bike posts on the forum and I am hoping someone can tell me if they have been able to motorize any of the felt bikes that have 24"x3" tires like the hot wheels bike or the red baron or the james dean bike. I have a friend going to felt tomorrow to see what he can get for me and I want to be sure that it can be done, otherwise I will go up to the 26" size models.
Thanks for you help
