Wheel flop refers to steering behavior in which a bicycle or motorcycle tends to turn more than expected due to the front wheel "flopping" over when the handlebars are rotated. Wheel flop is caused by the lowering of the front end of a bicycle or motorcycle as the handlebars are rotated away from the "straight ahead" position.
However, the larger the diameter of a caster wheel, the higher the caster support arm must be. Either the base of a low-hanging object must be lifted higher above the wheels, or the casters must hang out to the sides straddling the low-hanging supported object. While rotating around the vertical shaft, swivel caster wheels sweep out a space.
Caster angle and trail both influence the steering, albeit in different ways: caster tends to add damping, while trail adds "feel" and returnability. The caster wheel on shopping carts are an extreme case – the system is undamped but stable, as the wheel oscillates around the "correct" path. The construction has relatively high trail, but no ...

When each deck is pushed to the side, it causes the board to be pushed upward by the wheels' rotation against the gradient of the mounts.
The mechanism was invented in 1927 by Tullio Campagnolo, an Italian bicycle racer. He was frustrated when he attempted to change gears during a race. At the time there was but one cog on each side of the rear hub, so gear changes necessitated stopping, removing the rear wheel, flipping it over horizontally so that the opposite cog is engaged by the chain, and finally reinstalling the wheel.
Bicycle drivetrain systems are used to transmit power on bicycles, tricycles, quadracycles, unicycles, or other human-powered vehicles from the riders to the drive wheels. Most also include some type of a mechanism to convert speed and torque via gear ratios .
Klein was a bicycle company founded by Gary Klein that pioneered the use of large diameter aluminium alloy tubes for greater stiffness and lower weight..
