An autobike or automatically geared bicycle is a bicycle with a derailleur or internally geared hub (transmission) that shifts gears without intervention from the rider.
This is an Autobike Classic Ladies bicycle (stepthrough frame).
Never shift again!
There's not too many of these around anymore.
As seen on TV over a decade ago, this bike shifts by itself based on the speed of the rear wheel. There are 3 weights that move to the rim using centrifugal force. This pushes the derailleur that moves the chain onto different cogs.
I've replaced the original seat with a nice Schwinn Air Cushioned saddle.
The shifting works fine. The brakes work well. Overall the bicycle is in nice shape.
Color purple entwined with purple.
The bicycle is 40 inches from the very back of the frame where the center part of the rear axle on the back wheel, going diagonally to the frame that comes down from the handlebars.
Bicycle is 20 and a half inches from the center of the crank going upwards to the bottom of the seat where the metal ends on the frame.
From the ground to the seat itself before the seat is adjusted is 35 inches.
This bike has a steel frame and fork, aluminum rims and a very comfortable Schwinn Air Cushioned saddle.
