I'm 33 and it's the only lawnmower I will use. I have 2 gold series with the 3 speed trans and a silver series that I use to mow my moms lawn. They are tough a hell and it irritates my tree hugger neighbors. I tend to mix my fuel a little strong for that added effect! Ha ha
The heater is a definite plus, I'm looking to get a new power vent version tho. I'm not sure what a 29er is. It's a trek zr9000 with full suspension and hydraulic disc breaks. It's a sweet bike and one of the few models of trek still made in Wisconsin!
