HOW IT WORKS
The Hovertrax Prizma responds to the rider’s foot movements. Remember this. The Hovertrax Prizma 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 Prizma to no longer be parallel to the ground.
When the product is “on”, the gyroscopic mechanized balancing feature of the Hovertrax Prizma tries to keep
the foot platforms of the product parallel to the ground. In use, Hovertrax Prizma 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 Prizma as instructions to make the wheels move. Hovertrax Prizma
tries to re-level a forward tilt by accelerating, and tries to level a rearward tilt by decelerating.
Note: Do not lift the Hovertrax
Prizma off the ground when it
is turned on. Do not turn on the
Hovertrax Prizma in mid-air.
Moving and Changing Direction:
When a rider stands on the Hovertrax Prizma with an evenly weighted foot that is “level” on either
foot platform:
• Pressing toes on both feet downward moves Hovertrax Prizma forward.
• Pressing heels on both feet downward moves Hovertrax Prizma 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 Prizma 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 Prizma, 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
Prizma 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 Prizma 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 Prizma
does not receive any “signal” to interpret.
Riding Tip: Certainly the rider
may “lean” on the Hovertrax
Prizma, 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.
Periodic recalibration is recommended:
The Hovertrax Prizma 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.
