Thanks guys.

My inside diameter of my rim is just shy of 1" using my tape measure. I'll be towing our daughter in a bike trailer and average 15mph on my road bike, so that should be enough for her to be able to keep pace. I had no intentions of leaving her behind or anything, I'm a better husband than that. And I really do want her to get a hang of riding so she can become more interested and ride with me. She is very fit is used to skating 25-30 miles on some of the trails were on. Putting her on my road bike is a no go as she is 5'2" and the bike is too big for her and she has never tried clipless pedals before. If it wasn't too big I would slap flats on it, but the geometry would be harder for her. The bike I am converting was a present from my wife over 10 years ago, but the guy helping her guided her to a bike that was too small for me, but it fits perfectly for her so that is why I am going to convert it to fit her. So far I have already got her a big gel seat and ergo grips, as well as tuned the bike. The tires will be the finishing touch. Later down the road I'll probably swap out the front suspension fork for a rigid fork to make it a tad bit lighter.

The trail I plan to take her on is very flat, and completely paved the whole way. I'll start her on an easy pace with a target of 10-15 miles. It's going to be a nice weekend, so we plan to go late Sunday evening.

Sorry for what may sound as a "silly" question, we are all "noobs" at something at one point or another. As a firearms and safety instructor I deal with it every day with that in mind.

cheers
