My wife and I are planning to stark biking up in the mountains, but we don't have bikes. We looked at Wally world and liked the prices, but I know what you get that you pay for. We are just looking for something for some lite trail riding in the mountains every few weekend. What should I look for in a beginers bike. I would to only spend between $2-300. These will just be something to start off with to see if we like it. Is there any brands to stay away from?
