There have been numerous breakthroughs during my 30+ year love affair with cycling. I rode almost 4,000 miles in 1984 on a Jamis 'Dakota'. Toe-straps, hiking boots and a lotta cotton. Later on.....index shifting...suspension...clipless pedals....full suspension...etc...... I must say - though - this latest development - this ass - kicking all terrain dumpster of a bike - called a snowbike - this may be the coolest. I have wanted one of these for a few years but couldn't really justify the "7th" bike argument. Well kids, for where we live and what we do and how we live and how we get around.....this piggy of a hummer of a ride might just be the best investment I've made in years. I laughed more on the ride this am than I have on a long time. I felt like I was ripping west ridge, when the area wasn't even open. It really felt like powder turns. It was 17 when I left the house. Crystalized snow and ice. Maybe 5 inches on the ground. This thing levitates. It's the oddest feeling I have ever had on abike. It's like riding a bike with 20" of front and rear suspension...while the whole time...hearing clown music in your head. This morning's ride was a gift. If you don't have one of the these, and you don't really care about the cold....get one. Get one now. It's so fricking fun.
