Remember when you didn't think about the gears on your bike? Your bike had a bike sprocket connected to the pedals and a small sprocket connected to the back wheel an that's all you needed. Then you got a little older and got your first 10-speed. That bike had two sprockets up front and five on the back. In all likelihood, the shifters were a pair of levers connected to your bike frame near the handlebars.

Mountain bikes are designed for off-road riding. Whether made for racing or the more leisurely rider, there are four basic frame designs for mountain bikes: rigid, hard-tail, soft-tail, and full suspension.

The rigid (also commonly known as fully rigid) mountain bikes resemble a conventional sort of bike as you would imagine it. A rigid mountain bike has neither a rear suspension nor a front suspension.

Many bike speed records have been broken by recumbent bikes. Recumbent bicycles were banned from international racing in the year 1934 and they hadn't seen widespread use until toward the end 20th century.

A recumbent bicycle is a kind of bicycle which places the rider in a seated or supine position and rarely, in a prone position.

Recumbent bikers hold many world speed records for human powered, non-paced types of races.
