Maritime said:My experience is training wheels make for a poorer rider in the long run. Start on a pedal or push bike with not training wheels until they can ride, then move to the motorized version. The muscle memory to keep balance doesn't get developed right. Also, check in your area, the big commercial bike shows have the Yamaha riding academy, usually free with admission and any kid 6-16 can get instructions and ride around a course of hay bales, my son did it and learned enough to hop on the next dirt bike he had access to and ride all day. I posted vids on here of it, it was worth the 15 to look at all the bikes I can never afford new.
I dont know - I've built up a few of these things over the years for kids of family friends and the trainer wheels are a massive help when the kids are very young. Better to be able to ride than to have the thing fall on you (remember - these things are not as light as a pushbike).
Brad - you can get the trainer wheels like I posted earlier or the Stutter Bump ones that attach to the rear hub. The latter ones can snap off the mounts on the rear hub if the kids go over little jumps so be if you can make ones that attach under the footpegs they are the best.
And the other thing is these bikes can keep the dads fit as well. I've lost count of the number of times dads have had to run across to the other side of the paddock to re-start the bike when the kids fallen off it. One guy I know sold his kids PW and bought a TTR50 because it had electric start.....
