I still use mine regularly, usually with my son Caleb round the local coast up here or with Brian. Usually in the winter months for general off road work. Caleb has his On One Baby Fatty that he uses as his everyday MTB.
Must admit it has gotten a bit more work this year due to me still having to get another set of cranks for my 1 X 1. The 1X1 set up with Dirt Wizards is my preferred ride and is the best MTB of all time for me. It can do 95% of what the Pugsley can and far nicer for and more versatile for just about everything else.
