11.9 Tyres
11.9.1 Gocycle All Weather Tyre
Gocycle comes fitted as standard with specialised, all weather tyres which are designed to give the
best combination of low rolling resistance and puncture resistance in most weather conditions. To
maximise performance, we do not recommend that you use lower quality tyres than those supplied
with Gocycle.
WARNING! The traction or grip level of bicycle tyres such as the Gocycle All Weather Tyre
can reduce dramatically in icy or wet road surface conditions. Take special care when riding in
icy or wet road surface conditions.
11.9.2 Tyre Pressures
We recommend that you operate Gocycle with tyre pressures of 35 psi on the front and 40–50 psi on
the rear. This will give the best balance of low rolling resistance and comfort. Running a relatively
softer front acts as a “cushioning effect”, reducing shock loads to the motor fork components—
specifically the clutch and gearbox. Running the front tyre at lower pressures than 35 psi can improve
comfort and shock absorption at the expense of tyre performance, handling, and tyre life. Please
ensure that you are confident and comfortable with the handling and riding characteristics of the
Gocycle if you choose to run lower tyre pressures.
Do not inflate the tyres to more than 60 psi. Inflation pressures greater than 60 psi will reduce comfort
and the service life of the product.
WARNING! Never inflate any tyre on the Gocycle PitstopWheel to more than 60psi.
CAUTION! Inflating the front tyre to more than 35 psi places high shock loads into the
motor drive system (motor, gearbox and clutch) whilst using the power on acceleration or over
rough 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.
11.9.3 Changing Tyres
When changing a tyre, always use plastic tyre levers. Never use a metal tyre lever as you will damage
the wheel rim.
Note the correct direction of the tread of the Gocycle tyre in relation to the wheels (see figure below).
The size of the Gocycle rim is generally compatible with BMX-sized tyre (406x40-47) from 1.75" to
2.15". Because tyre construction and quality vary greatly from manufacturer to manufacturer, we can
only recommend that you use Gocycle approved tyres as available through the Gocycle webstore.
WARNING! Bicycle tyres do not last forever. When the tread depth is critically low and the
centreline grooves in the tyre have worn down in any part of the tyre, it may be dangerous to
continue to ride on the tyre, and in this event, we recommend that you replace the tyre.
