Update: we have been on 3 rides now. The first one was 8 miles on the bike path. She did so well that the second was upped to 20 miles on the road with mild rollers. Dropped her chain twice but otherwise she did great. Our last ride was 30 miles bike path/road combo with rollers and two rather challenging hills. She's getting the hang of shifting and has increased her speed from about 8 mph to a solid 12-13. I think I've created a monster! LOL. She'll soon be smoking me on the road.
The bike goes to the shop on Friday for some adjustments and slight fit issues but she is so excited and her family is in total shock!
