I am getting a new bike and want to give my old bike to my daughter who has expressed interest in bike riding with me on some local bike trails. She hasn't rode since she was a kid and is in her 20's now. I currently have a giant cypress and she says the only way she would ride if she knew she would not break the tires. I have the original tires on now which are 700 38 - I think she would do better on narrower tires like a 32 as the cypress also has front suspension - and I would want new rims with extra spokes for her. Can anyone suggest tires, rims, # of spokes for me to put on the bike. She is 325 lbs - I want to encourage her exercise and don't want her to have a bad experience. Also, I still have the original comfort seat - Is it best that I leave it for her? The bike trail we will use is approx. 7.5 miles round trip.
