Why would anyone want to ride a recumbent bike, you ask?let me count the ways:
1. They’re fun to ride.
2. They’re really cool.
3. They’re oh so aerodynamic compared to uprights or diamond frames, (that’s how recumbent riders refer to the bikes that the rest of the world rides).
4. They’re totally made for touring; super comfortable; better view—no need to bend your neck at harsh 45-60 angles; and super easy to haul your gear. (Check out the pannier mounts and panniers in the collage below. Volae Century ES Touring bike.)
5. There’s NO PAIN, anywhere—no saddle sores, no carpal tunnel, no numb fingers, no numb genitals, no sore lower back, no shoulder spasms, no neck pain, and certainly no Shermer’s neck. There’s no pain anywhere, even after riding a 200, 300, 400, 600, or 1,200K miles.
6. Recumbents make it possible to ride for as long as you have time. Over the last 5 years I’ve ridden 10-14,00 miles each year with daily rides ranging from 30-150 miles all while working nearly full time. Racking up those kinds of miles would be tough year after year on an upright given all the stress on various body parts.
7. Not everyone has a recumbent bike and many others have never seen a recumbent before, so they’re great conversation starters (sort of like walking your dog in the city can be a great way to meet people you don’t know). Once given the invitation to talk to a stranger, you have the opportunity to encourage an un-biked person to try riding.
8. Finally, recumbents lend themselves nicely to those of you who have engineering genes and who like to build things.
