AirShammy. Just over a hundred bucks and works like a charm. The air is slightly warmed and the supplied hose has a soft rubber end and is plenty long.
+1 on airshammy, works like a champ I have been using it for almost a couple of years now, mounted on the wall next to the garage utility vac and the hose is plenty long to reach.
sears leaf blower, less than $50. You just want to blow the water out of the holding spots anyway right? Wash, blow, polish with microfibre in less than 20 minutes.
A couple of years ago, I followed a thread like this and bought an electric leaf blower to use as a dedicated bike dryer. It did OK, but my neighbor brought over his Metro Master Blaster and I was sold....it's much easier to use and easily twice as fast. This unit has two 4hp motors and costs ~$300 shipped currently. That's a lot of money, for sure, but we have two HDs and two Labradors, and the wife likes a clean bike.
If you go with a leaf blower, don't ever try a Master Blaster. I was happy with a Virago 750 once upon a time, too, until I rode a Harley.....
