Basic Rider Optimization Training for the Segway HT Page 13 of 106

Instructor Guide and Participant Workbook Rev 3.5i - January 2004

Minimum Weight Limit

The rider’s weight must not be less than 100 lbs. (45 kg). If the rider is below the minimum rider

weight limit, she may not be able to ride safely because she cannot shift her weight far enough

back (behind the centerline of the wheels) to safely slow down and stop, especially when riding

downhill. Also, riders below the minimum weight limit might fail to properly activate the Segway

HT’s balancing system.

Structural Weight Limits

Increased risk of damage to the Segway HT is another consequence of exceeding the maximum

weight limits. Heavier payloads place greater stresses on the Segway HT. Segway’s testing has

shown that the stresses created by a payload within the total payload weight limit (with any cargo

not exceeding the applicable cargo weight limits), ridden on a wide variety of terrain in

accordance with the instructions in this Workbook will not damage the Segway HT. Just like the

dynamic weight limits, several factors affect the loads transmitted to the Segway HT:

> Skill level of the rider

> Payload (weight of the rider and all cargo)

> Surface condition (obstacle height, etc.)

The stresses created by exceeding the rider or cargo weight limits, especially when riding on

uneven terrain, could damage the Segway HT.

Handlebar Cargo

The total weight of any Handlebar payload plus any other attachments hanging from the

Handlebar should not exceed 10 lbs (4.5 kg). Exceeding this limit interferes with the Segway HT’s

balancing ability and could cause the Segway HT to accelerate on its own, risking injury and

damage.

Side-bag Cargo

The total weight of each Segway-approved side cargo bag should not exceed 30 lbs (13.6 kg).

Exceeding this limit interferes with the Segway HT’s balancing ability, and could cause the

Segway HT to tip over sideways, or increase the difficulty of stopping, especially when riding

downhill.

Top Key Speed

Top Key speed refers both to forward speed limits, and turning rate.

The ease of controlling your speed based on the riding environment is the relevant metric. The

intuitive control of a Segway HT means that in crowded pedestrian environments, the Segway HT

can easily go the speed of those around you, from zero speed to the top Key speed on any Key.

The intuitive self-balancing control and stopping ability allow a Segway HT to easily travel at the

speed that is comfortable in any environment. Unlike a bicycle or scooter, there is no minimum

speed required to maintain balance, nor is there a throttle which makes velocity difficult to control

at lower speeds.

Turning sensitivity changes depending on the key used. The most responsive turning rate is

achieved with the Open Environment Key. It is very important to ride and turn with control,

especially as you increase your top forward speed.
