roads. Just like in a car as you would not accelerate rapidly on very rough roads, do not use
motor power when going over potholes or speed bumps or similar obstructions in the road.
Operating the Gocycle with a front tyre pressure greater than 35psi and/or using the motor
assistance on rough terrain, against these recommendations, will invalidate the warranty.
WARNING: Never inflate a tire beyond the maximum pressure marked on the tire’s
sidewall or the wheel rim. If the maximum pressure rating for the wheel rim is lower than the
maximum pressure shown on the tire, always use the lower rating. Exceeding the
recommended maximum pressure may blow the tire off the rim or damage the wheel rim,
which could cause damage to the bike and injury to the rider and bystanders.
The best and safest way to inflate a tire to the correct pressure is with a bicycle pump that has a built-
in pressure gauge.
WARNING: There is a safety risk in using gas station air hoses or other air compressors.
They are not made for bicycle tires. They move a large volume of air very rapidly, and will raise
the pressure in your tire very rapidly, which could cause the tube to explode.
Tire pressure is given either as maximum pressure or as a pressure range. How a tire performs
under different terrain or weather conditions depends largely on tire pressure. Inflating the tire to near
its maximum recommended pressure gives the lowest rolling resistance; but also produces the
harshest ride. High pressures work best on smooth, dry pavement.
Very low pressures, at the bottom of the recommended pressure range, give the best performance on
smooth, slick terrain such as hard-packed clay, and on deep, loose surfaces such as deep, dry sand.
Tire pressure that is too low for your weight and the riding conditions can cause a puncture of the tube
by allowing the tire to deform sufficiently to pinch the inner tube between the rim and the riding
surface. This may also result in rim damage.
CAUTION: Pencil type automotive tire gauges can be inaccurate and should not be
relied upon for consistent, accurate pressure readings. Instead, use a high quality dial or
digital gauge.
If you need help with tires, ask your Gocycle dealer to recommend the best tire pressure for the kind
of riding you will most often do, and have the Gocycle dealer inflate your tires to that pressure. Then,
check inflation as described in Section 1.C so you’ll know how correctly inflated tires should look and
feel when you don’t have access to a gauge. Some tires may need to be brought up to pressure every
week or two, so it is important to check your tire pressures before every ride.
Gocycle tires have unidirectional treads: their tread pattern is designed to work better in one direction
than in the other. Be sure that they are mounted to rotate in the correct direction as shown:
5.6.2 Tire Tube Valves
There are primarily two kinds of bicycle tire valves: The Schrader Valve and the Presta Valve. The
bicycle pump you use must have the fitting appropriate to the valve stems on your Gocycle.
The Schrader valve (fig. 18a) is like the valve on a car tire. To inflate a Schrader valve tire, remove
the valve cap and clamp the pump fitting onto the end of the valve stem. To let air out of a Schrader
valve, depress the pin in the end of the valve stem with the end of a key or other appropriate object.
Gocycle rims are designed to use Schrader type valve tire tubes. Ensure that the tube you use is
compatible with the size of the Gocycle tire. Consult your Gocycle dealer or Gocycle for assistance.
The Presta valve (fig. 18b) has a narrower diameter and is only found on bicycle tires. Gocycle rims
are not designed to be compatible with Presta valve type tire tubes. Do not use Presta valve type tire
tubes on your Gocycle.
