<P> Mountain bike suspension technology has made great advances since first appearing in the early 1990s . Early full suspension frames were heavy and tended to bounce up and down while a rider pedaled . This movement was called pedal bob , kickback , or monkey motion and took power out of a rider 's pedal stroke -- especially during climbs up steep hills . Input from hard braking efforts also negatively affected early full suspension designs . When a rider hit the brakes , these early suspensions compressed into their travel and lost some of their ability to absorb bumps . This happened in situations where the rear suspension was needed most . When braking efforts cause the suspension to compress it is referred to as brake squat , when braking causes the suspension to extend it is called brake jack . </P>
