Early this morning I went out to the Blackburn velodrome to have my first ride in a carrot. It was very interesting. These things are extremely twitch and difficult to balance which sent me sliding down the track a few times loosing some skin in the mean time. Once you get up to speed they do become a bit more stable but I found myself consistently adjusting the bike with by butt checks to keep it on the red line.
The Carrot is owned and build by Tim who works for Kona and this morning was it's first ride. The lid didn't allow me to turn the pedals because of a clearance issue but once this is resolved Tim thinks sitting on 50km/h for sustained periods is achievable.
