My son is 3.5, about 41 pounds, & 40" to 42" tall. We are buying him his first bike soon. Maybe this weekend. I'm also getting my new Giant Yukon this weekend, if it comes in. I know he wouldn't be in a trailer long and they are expensive. LBS recommended a TAB. I'm unsure of his size and attention span. I don't want him to fall off basically. I kind of think I'm worrying a little too much!
So, how early did you folks who have experience with these things put your little folks on them. My wife and I would like to be able to take longer rides together and include our son.
TIA for you comments.
