I guess my brain and fingers were not cooperating. What I meant to say, is that I kept my speed under 25 mph on the few downhill sections on my route to work. I can easily get up to 30-40 mph on these hills, but given todays winds, my Mango started moving side to side too much once I hit 25 mph. Ah well...these velomobiles are great for high speed commuting to work.
