Yeah, I know this isn't a bicycle but a downhill's a downhill! 
The Bullant; timber gravity kart. Pneumatic golf buggy wheels on the front and 330mm X 70mm solid rubber on the rear end. Rear end slide was essential for turning which meant it was a killer on hard surfaces because of excessive grip. Handling became much easier after I figured out a self-centering system for the steering and while the braking system did work from a mechanical perspective it did absolutely nothing to slow you down; it needed discs mounted to the inside of each rear wheel as the callipers were useless. 
Once clocked by a trailing car at 48kph. 
Fantastic bush toy!

Off the wheels with smashed clavicle & ribs since early September. Almost forgotten what it feels like to ride :'(

Internal Hub Gearing System

Sturmey Archer is only one of the manufacturers of these patience-testing systems and while digging up these schematics I was surprised to discover that this gearing system is still a viable option in the cycling world; I honestly believed the derailleur system had rendered it obsolete. Not so, apparently.
Obviously, the technology has been refined since the days when I rode alongside the T-rex and Brontosaurus but it is nevertheless an internal system and that makes it fiddly.
My one and only internal gearing hub bike was my second bike after my first - a Speedwell Scout 24" deathstar - and the hub went south on me twice. The first occasion I took it back to the guy I had bought the bike off for the princely sum of $6 and he fixed it while I watched, but the second time it went I just gave the entire bike to my bike-build buddy who swapped the rear wheel for an array of parts so I've never actually worked on one.
There are, however, YouTube videos covering the surgical procedures associated with these torturous gizmotrons available.

I love bicycles but I am no friend of motorcycles and the two-wheeled death machine pictured is why. My neighbour on the undivorced side of our house had one of these which he used to "water his back yard". Yep, he'd ride this thing from tree to tree with the garden hose in his hand watering; barrel of a man.
He offered me a ride one day and I'm pretty tall; I hit the gas, slipped off the back, somehow twisted the throttle into the let's go as fast as we can position and unceremoniously zipped across his yard straight into a strand-wire fence. Pedal-power since.

+Stuart Bates word. We've had heaps of deaths here from quad bikes but the farmers still insist on using them. And letting their kids use them.

Completely unsatisfied with the deadlines of the Dragster and the Mustang - the Dragster frame was a little longer than the Mustang though similar in design - someone, who obviously was of the mind to rid himself of a pesky son, came up with this design. 
This is the Raleigh Chopper, although many brand variants flooded the 70s market. 
As with anything, these little beauties came with an operators manual and under the heading of Cornering it simply read; NOT ADVISABLE. 
Clearly, the handle bars were made wide enough so as to not impede the rider as he sailed through them on his way to yet another facial scar.
You didn't need to hire a hitman to get rid of little Johnny, you just bought him one of these!

Hahahaha. I'm surprised the thief didn't return it and report you for an unsafe device.

This is the kind of big boy bike you need to get around on city streets.

Had two of these back in the 70s as well. First one was a 3 speed Sturmey Archer back pedal change hub. Banana seat and sissy bar exchanged for a pear seat. The second was high falootin' technology for the time; 3 speed triple sprocket cluster derailluer system. Pedalling forward to change gears; man we thought we were the shit!

This is pretty much what we used ride bush trails on back in the 60s and 70s. The only change we'd make was the handle bars. Ya get to hug a lot of trees riding these badboys down a wooded hillside!

¨ My favorite local commuter rail system gave me a little birthday surprise, fresh new green signs announcing that they were finally adding straps to the bike carriage space so that our bikes won't fall over, roll away, etc. Isn't that nice? They didn't actually add the straps, though. I had to secure my bike with my reflective ankle strap, as usual.
Since BART didn't provide a strap to go along with this sign, I secured my bike with my own leg strap.

[Highland Games] Cycling racing

Highland games also have a lot of more traditional kinds of competitions such as running and cycling. However cycling in this pictured event was done on a track traced on grass, which isn't necessarily the easiest medium to cycle on for a race.

I recall Friday night bike builds down the road at a friend's house back in 77; my Dragster from 74 had long since died and I was back on a Speedwell Scout 24" coaster hub which I inherited as a result of my next-door neighbour's divorce and relocation back to Canada.
Craig had a few frames, rims, tyres and tubes, and a treasure chest of parts so there was no telling what would be wheeled out of the shed at the end of the night. The trickiest job of the build was always putting a refurbished rear hub together as it was like performing dentistry on a mosquito; much easier though than the Sturmey Archer hub.
We discovered that it IS possible to put a coaster hub together wrong and not be aware of the error until you needed the brake. Fun and games! 
This article with discuss the basic bearing service of coaster-brake hubs, also referred to as a "back pedaling brake."

I watched it being done once; that was enough for me!

1974 Yamaha Bicycle; the shock of the shocks! Predominantly purchased by parents, who drank tea in the afternoons, for their darling little Johnny's. They had a price tag bigger than Quo Vardis; heavier than a Sherman tank but awesome for being stupidly brainless on. Having suspension meant that you could jump it off anything. Unfortunately the pedals and crank arms were standard issue of the day which resulted in an instant alto voice when the pedals bent as you landed and crushed your unmentionables on the unforgiving seat. Nice yellow though!

New bike rack invented that uses less space. This is another way to encourage more people to bike than drive, especially in cities! Check it out...

Chicago has beat out New York in this year's Bicycling magazine ranking of the most bike-friendly city in the United States, meeting an ambitious goal the mayor set in 2011.

The discussion in the comments at the bottom of that page about the algorithms is personally interesting to me since I have a similar bicycle route-finding w/ elevation gain web page.
