Sail for Recumbent Bike (High Wind)

I made this by taking the basic sail design and adding wings made from lawn chair tubing, vinyl and duct tape, attached to the backpack frame with baling wire. The crossbar was made from an old ski pole and the fairing comes courtesy of Windwrap and worth every penny. I tested it through the Salinas Valley with tailwinds averaging between 15 and 20 mph and for the most part, it rocked.

In general, a sail will be helpful up to windspeed but no faster, but really helped compensate for the weight of the bike, which was fully loaded with pack, camping gear etc. On uphills and in high winds it felt like magic.

Probably the most noticeable effect was in cities, where people of all ages and demographics would stop to stare, chat, give a thumbs-up or say "Cool Bike!" And let's face it, when a 12 year old says you've got a cool bike, you do.

Despite the aesthetics, the design and materials are much heavier and more unwieldy than necessary - nice and strong for high winds, but fairly impractical otherwise - so I'll probably try working with nylon and tent materials next. Awfully tempting though to take this up to the high desert and see what it does in a really big wind.

Radical Thinking


Corporations and politicians are fond of telling us that “Children are the Future.” They’re not: they’re the present. (Look down, or check in front of the TV.) The future is a little bit more abstract than that. It will be populated by our children’s grandchildren and their children and grandchildren and very few people are asking us to think about them, least of all politicians and corporations.

One organization that actually is dedicated to this sort of long-term thinking is the Long Now Foundation, described here by Michael Chabon. Although trying to project an arc for the next 10,000 years is probably a bit heady for most, it’s good to know that someone’s doing it. For me, just getting people to think a couple of generations ahead is radical enough.


This sign measures about twelve feet across and was placed over the eastbound lanes of the Santa Monica Freeway between La Brea and Crenshaw at 1:00 p.m. yesterday and was still up four hours later. Let me know if you see it.
