Q: Are there any cheap shuttles that will take me to the top? I'd like to have my car waiting for me at the bottom -Cyclosaur
A: There are no legal commercial mountain bike shuttles to the top. The only commercial shuttles require you to ride down the road, not down any of the trails.
Q: Can you start at the top and just do downhill? -Jeff Barber
A: Yes! You'll need to pay the toll to drive up ($10 per person in the vehicle). More info: http://www.singletracks.com/blog/mtb-trails/shuttling-pikes-peak-descending-an-iconic-colorado-14er-on-mountain-bikes/
