Xootr
wheels are the key to its high performance. Our wheels are custom
made for the Xootr and are not available on any other product. These
wheels are made by molding polyurethane onto aluminum centers. Our
wheels (pictured at left) offer the lowest rolling resistance of any
small-wheeled vehicle.
Why
should you care about rolling resistance? In a human-powered vehicle
travelling at speeds of about 10 mph (16 kph) on level ground, nearly
all of your effort goes into overcoming rolling resistance. Rolling
resistance is pure dissipation of your energy...the less resistance,
the less effort you have to apply to get where you're going. See
the chart below for a quantitative assessment of what this means
to you. Frankly, after riding the Xootr, skateboards, in-line skates,
and competitive scooters feel like they are rolling through mud...the
Xootr is that fast. |
