There are lots of people switching to recumbents. Of course you will see a lot of older age riders on
recumbents because it provides a lot of physical relief. This leads to some people viewing recumbents
as being slow since these often less atheletic riders are the visible indicator. However, that is
simply not true. Recumbents are the fastest bikes on the road for the training level of the rider.
The reduction in wind drag provides a dramatic advantage. I can coast from 20mph to 50mph on local
hills here where standup riders can not get above 40mph, tucked and pedaling. I don't have a windshield
or shell on my bike. I don't need it to ride at the level that I want to ride. If I added a shield, I
probably would not get much exercise when riding with my 18-20mph riding buddies.
The great thing about a recumbent is not that it is faster, but that it is painless. It unloads your
back, your arms, your wrists etc. from the stresses that you have on a standup bike. When I go on 60mile
rides, I stop to eat and drink, and rest my legs, but never because of inordinate pain in my limbs or
back due to awkward riding position. It makes it possible to ride a long way without being worn out!
