when was the first full suspension mountain bike made
Bicycle suspension 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 â€” 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,[6][7] when braking causes the suspension to extend it is called brake jack.
