Hello, i am trying to loose weight for a personal goal of 100off and i decided to park my car and ride a bike everywhere. i asked on yahoo answers about some walmart bikes and got flamed hard for it so i figured id come somewhere i can actually learn. what i did learn from that, though, was what im looking for is probably a hybrid bike. i want to be able to ride it to the local woods and go through the trails, they are super simple walking trails nothing special. i was looking at this Walmart: 29" Iron Horse Men's Sinister 6.1 Mountain Bike but like i said, flamed. so i started to look at schwin (the only other place i know). im 6'3 290lbs right now but my goal is 220. anything you could tell me would help. oh and there are no bike stores near me, there was 1 and it closed. thank you!!
