I'm looking for a decent mountain bike that I can chase my 3 year old on. I used to ride $3000-$5000 bikes but got out of it a 10 years back and sold everything off. I can't justify $1000 to just follow my kids, but I also refuse to go to Crappy Tire or Walmart and get one there. So, if you have a bike that is taking up room in your garage or you just want to upgrade, please let me know what you got. 18" - 20" frame please, hardtail, decent fork, preferred.
