Hi everyone, I recently decided to get into cycling for fitness, I was walking 4 miles a day pushing a stroller with my 3 year old riding in it and my 5 year old riding his bicycle next to me. I realized that if we had another bicycle and a trailer we could all ride together. I thought about getting a bike at the LBS but I didn't know how much we would do it so I went to wal-mart and got a Schwinn Aluminum Comp. mountain bike. It didn't take me long to realize how much I enjoy this sport. The rear sprocket failed within 125 miles and I took it to the LBS for a repair, while I was there, I test rode a TREK 8.2 and was blown away, I did a little research and decided I wanted an 8.3 because of the lockout fork, for road riding and I can have some suspension for playing with the kids in the yard. Well, I've got my 5 year old doing 8.5 miles a day, I really think he's ready for a quality bicycle and as for me this morning I rode the Schwinn pulling the 3 year old for 10 miles and I did it in 51min. 25 seconds. There are several decent hills on the route I took and I was thinking if I had a better quality hybrid I would have an easier time and possibly do some 25-30 solo rides. I don't think I'd want to pedal the schwinn much more than 15-20 miles, anyway am I ready for a "real" bike or do I need to completely wear out the mountain bike? I will attach a picture of my current rig, I know I'm not wearing a helmet, but we were just posing in the park.
