When was indexed shifting introduced?
1985
Historical note: Indexing was introduced en masse in 1985. Before that, people rode bikes, people didn’t complain, and people shifted in friction.
Do all bicycles have gears?
Most modern bicycles have gears, although not all of them do. The number of gears varies from bike to bike. Fixies, single speed bikes and some folding bikes come without gears.
How did they come up with the gears for bicycles?
The drivetrain system improved over the years with the addition of gears. In the earliest days riders had to dismount to change gears. Among the first methods of two-speed bicycles was a wheel with a sprocket on each side of the hub, and to change gears riders had to remove the wheel, flip it around and remount the bike.
When was variable speed gearing invented for bicycles?
“It was reported that between 1877 and 1906 in London there were 750 patents for variable speed gearing, however, they were not commercially desirable. Most people were satisfied with their single speeds. In 1895 Frenchman Jean Loubeyre patented a device for derailing the chain from one sprocket to another.
What was bike made out of 25 years ago?
Twenty-five years ago, bicycle makers bought tubes of whatever material—steel, aluminum, carbon fiber, even titanium—and then figured out how to link them up to make a bike. Geometry was mostly limited to what amounted to a series of triangles, and carbon fiber was pretty unaffordable.
What’s the history and evolution of the bicycle?
The History & Evolution of the Bicycle. The bicycle has a history that goes back about 600 years and is quite different than the bike as we know today. Many major innovations have dramatically transformed the bicycle’s form and features over the years. Earlier models had two wheels, but no way to steer, and even required a running start.

Is it better to have more gears on a bike?
Let’s be clear about one thing — having lots of gears is not about making the bike faster. A bike with 30 or more gears is not an indication of a machine designed to break the land speed record any more than a bike with only a single gear, assuming similar ratios.
What kind of gears do singlespeed bikes use?
Singlespeed bikes use a single cog that can freewheel and allows the rear wheel to rotate without the pedals moving. Fixies are even more rudimentary, with the rear cog ‘fixed’ in place, meaning if the bike is moving, the drivetrain moves, so you always have to pedal.
