HOW IT WORKS

The Hovertrax 2.0 responds to the rider's foot movements. Remember this. The Hovertrax 2.0 moves due to
fore and aft foot platform tilt caused by the rider's foot (or feet).
Movement, speed, and stopping are controlled by the degree to which the rider's feet cause the foot
platforms of the Hovertrax 2.0 to no longer be parallel to the ground.
When the product is "on", the gyroscopic mechanized balancing feature of the Hovertrax 2.0 tries to keep the
foot platforms of the product parallel to the ground. In use, Hovertrax 2.0 then detects changes from "level"
which are caused by fore and aft pressure on the foot platform(s) applied by the rider's feet. Such changes
are interpreted by the Hovertrax 2.0 as instructions to make the wheels move. Hovertrax 2.0 tries to re-level a
forward tilt by accelerating, and tries to level a rearward tilt by decelerating.
Moving and Changing Direction:
When a rider stands on the Hovertrax 2.0 with an evenly weighted foot that is "level" on either foot platform:
• Pressing toes on both feet downward moves Hovertrax 2.0 forward.
• Pressing heels on both feet downward moves Hovertrax 2.0 backward.
• Turns are done by putting more downward pressure on the front side of the foot platform on the
outside of the turn.
• A rider can spin in place by pushing downward on the front edge of one foot platform while
simultaneously pushing downward on the rear edge of the other foot platform.
Accelerating and Stopping:
• To go faster or to slow down, press the foot platforms at a greater angle for "more" and reduce the
angles for "less".
• When slowing or stopping, if you continue to apply force to the edges opposite the direction of
travel, you may not only stop but continue on to reverse your direction.
How does this happen? The fundamental principle is that the Hovertrax 2.0 is designed to be "at rest" when
the foot platforms are level – and the gyroscopic mechanized balancing feature detects the "levelness" of the
product. This same feature detects foot movements that cause a foot platform to no longer be "level" and it
interprets these changes as orders to move.
That's it. That's how it works. It does what your feet tell it to do, and the product "self-balances" itself in order
to be ready to detect and implement the instructions provided by a rider's feet.
Understanding this principle is important for obvious reasons. It also suggests some obvious warnings for
riding the Hovertrax 2.0, such as:
Do not jump up and down on it: If you remove a foot (or both feet), if you then land back on the
Hovertrax 2.0 and cause the foot platform(s) to change position relative to "level" in any degree, the machine
could and will react by moving immediately in response to an "instruction", which can result in loss of rider
stability, balance or control.
Shifting Weight Alone is not the Issue: Do not presume that shifting weight alone controls motion – or,
for that matter, that not shifting weight equals "stability". Shifting of rider weight may be associated with
increase or decrease of foot pressures on the foot platforms, but it is the action of the feet on the foot
platforms which instructs Hovertrax 2.0 to move. Conversely, if you were to shift your weight without altering
the placement or angle of your feet, so that the foot platforms remain level, the Hovertrax 2.0 does not
receive any "signal" to interpret.
Periodic recalibration is recommended:
The Hovertrax 2.0 self-balancing features are calibrated to function with a detected "resting position" that
is level. Over time and usage, recalibration may be needed to assure "level" status. If inaccurate calibration
persists, this could affect the operation of the product by sending instructions to the motor(s) to move that
may differ from the intended motion.
To calibrate the product:
• Turn power OFF.
• Manually adjust the platforms so they are parallel to the ground.
• Turn power ON and HOLD until it beeps and lights flash (approximately 15-20 seconds).
• Turn power back OFF.
• Calibration complete.
Once the product has been calibrated, no matter what position (angle) the platforms are in when it is
turned OFF, the platforms with automatically self-balance themselves back to the calibrated position
when turned ON.

Riding Tip: Certainly the rider
may "lean" on the Hovertrax 2.0,
but leaning only affects the
foot platform's position to the
extent the rider's feet change
their position. If the rider's
ankles are held at a consistent
90° angle, leaning will result
in tilting. Note that leaning
can exaggerate shifting of
weight, which may affect the
ability of a rider to recover to a
level posture – increasing the
possibility of loss of balance.
