"Be One With Your Bike!"

Be one WHAT with your bike?

#6 Grab bar--I see no possible bad consequences to having that poking out the front of the saddle. Nope, not a one.

There's yet another style of swing bike. https://www.americasbikecompany.com/...gkingelite.htm

So it was basically a treadle-pedal design build with what looks like leftover Erector Set parts? (And yes, I am dating myself.)

The treadle designs died out a long time ago (like somewhere around the 1890s, if memory serves). You don't suppose there was a reason for that, do you?

"Currently Unavailable"? Egads. :(

I've skate sailed with a somewhat similar sail. But no attachment to the sail besides hands and body lean. And simple skates. (You do have to know how to skate.) Skate sailing can be very fast. My dad, who was very good, was clocked by police radar at 60. I've probably done 45.

Big safety plus - the sail usually aerodynamically eases your falls and falling on ice is road rash free.

Each side of the rear hub had a ratcheting gear. One side reloaded (noisily) while the other side drove.. Shifting gears was accomplished by moving the attachment point on the upper arm of the treadle. When you did it, it felt like you just broke something.

With the power delivered by both feet one crank length in front of the bottom bracket, if you got out of the saddle the front end was so heavy, you couldn't pull the front wheel up over a dime on the street.

I thought about that myself. These days, most people carry a three axis accelerometer (i.e. smartphone) around. Trouble is that unless you're moving at a steady pace and in a linear fashion, there's no accuracy. Sadly, my current cheapie (I refuse to buy an expensive device given the fragility and longevity) doesn't have a barometer, so I look at Google earth pro for a guess at the day's climbing. I might get a Motorola soon that has the barometer and a compass, but it'd be still far from a flagship.

This one's back! https://halfbikes.com/

A buddy's dad built a sail-bike attachment when we were kids. His had the sail in front, with a boom you had to lift over the handlebars to come about. Unsafe at any speed!

Yeh, but there’s a sign up for when the 2021 model becomes available!

rear A arms were angled, slap the control to the right and the right rear wheel dipped causing the trike to go right. Pretty ingenious. The problem was the play in the bushings. Go on a descent and near terminal speed wobble.
other problem was it was low slung, drivers crossing a sidewalk did not see the vehicle.
one of those industrial designed concept products that would never be tolerated by the lawyers today. Would never have made series production.

Funny, but you know that's not a real product, right? This is a novelty/prank empty gift box. There are many to choose from.

That Item is a motorcycle steering damper. Massive overkill on a bicycle but these steering dampers are quite useful on motorcycles in various forms of competition and have been around for a very long time in friction and hydraulic configurations. I run as a guest of Southern California Timing Association at El Mirage dry lake (https://scta-bni.org/el-mirage-general-info) land speed events, 131 miles per hour on a old Harley street bike isn't to bad for an old man. The steering damper in the photo is a more modern configuration then the one shown above, I wouldn't run without one.
