Additional Information on Wear
Components of PACE are subject to higher wear when compared to bikes without power assistance. This
is because PACE can travel at higher average speeds than regular bicycles and has a greater weight.
Higher wear is not a defect in the product and is not subject to warranty. Typical components a˜ected are
the tires, brake pads and rotors, suspension forks, spokes, wheels, and the battery.
When the useful life of a component is surpassed it can cause unexpected loss of function. This
can result in serious injuries or even death. Therefore, pay attention to wear characteristics
such as cracks, scratches, or changes in the color or operation of components which could
indicate useful life has been exceeded. Worn components should be replaced immediately. If
you are unfamiliar with regular maintenance, a certified, reputable bike mechanic should be
consulted.
