Richard Freytag commented on the R20 (Jun 9, 2011, 11:13 PM)... Well the first thing I'd say is that is breaks down into little pieces small enough to fit into a standard hard-case bike box. Helped a lot in my adventures. The mid-gearing meant I could add a front ring and get to a gear low enough to pull tree stumps or bike uphill slower than most people when they are standing in one place (ok I exaggerate a little). The short wheelbase was helpful in staying upright when going that slow. I'm 6'3" and a very short stop would pitch me forward and I would be standing. I think in many years of biking that happened 4 times. On tours I'd load up the back to ridiculous levels and things evened out. It is the most disagreeable blue-green color however. Must have been found in the discount bin. The seat webbing had to be completely reworked. But for a early model it has held up pretty well. It is not a fast bike because you lose 2% instead of 1% due to the extra mid-gears. But when on a long ride it didn't matter. The cushion under the seatback (two 1" thich rubber grommets), probably soaked up a little more energy too. The seat was very comfortable. The fact that it hit me below the scapula meant that I could brace seat-back to pedals when going over particularly big bumps and the cushion under the seat back and my legs kept me from getting hammered in the backside. I really liked the underseat steering as they would take the blow if for some reason I did go down.
