I tried to beat the heat today with an air conditioner on my back at 6mi.I took a backpack placed two ice packs in it and 4 cold water bottles along with my regular riding gear.It worked except the pack was too heavy and caused the front tire to loose traction.Then there was the minor problem of the front tire popping wheelies without notifying me.Finally we get to the counter weight situation.When I turned right the pack was going left ,and of course when I turned left the force went to the right.I must have looked drunk on the bike.Of course my experiment was performed in the twisties.Back to the drawing board.
