The wheel
The wheel is the most important part of the uni-
cycle and ought to be of the highest quality. A
good wheel should have a metal rim made
from alloy or steel. Plastic wheels will
quickly break.
For a 20” wheel, 36 spokes
should be the minimum. For
smaller wheels, 12” to
18” in diameter, 20 - 28
spokes are acceptable,
because their riders are
smaller and thus weigh
less than 30 kg (65
lbs). Wheels intended
for more extreme use
can have 48 spokes;
more spokes makes a
wheel stronger, more
reliable and easier to
true. Eyelets at the spoke
hole allow a higher spoke-
tension spokes.
Rims:
Steel rims are heavy.
Alloy rims are sturdy and lighter and rustproof.
Double-walled alloy rims are the strongest and yet
lightest rims. This is an example cross-section of two of
our double-walled rims:

Tires:
Tire designs vary significantly depending on the in-
tended use. Standard tire: Normal bicycle tires are okay
for most ordinary riding.
Indoor/Freestyle tire: These can be ridden at much
higher pressures, offering more smoothness and less
rolling resistance. A white or light color allows you to
ride indoors without marking the floor.
Muni/Trials tire: Wide tires with an aggres-
sive tread pattern, these can absorb the
impact of drops and offer better rebound
and traction.
