I am researching into faired recumbents, bicycles or trikes, such as the Velomobile Quest or the Sunrider. I'm interested in cycling long distances as a daily commute and for touring, but have no interest in racing or mountain-biking. My current, upright bicycle (Koga Miyata) has a Rohloff gear and on my trips, I use both the smallest and the largest gear regularly. According to Rohloff, typical derailleurs do not have a higher gear range than the Rohloff Speedhub (which has 526%), although Wikipedia reports gear ranges up to 700% for derailleurs.
Faired recumbents can be really heavy (45 kg for the Sunrider) and really fast (2% downhill, 100W, 63.8 km/h, but also 30% faster than racers when flat). Really fast means one wants to have a very high gear, but really heavy means one also wants a really small gear to make it up steep slopes. Considering that I'm already using the full 526% range on my current upright bicycle, I wonder; do heavy, faired recumbents need more gear range than upright bicycles? I love my Rohloff, but should one consider getting a higher gear range on a faired recumbent?
