Quick release clamping system
The front wheel on all ElliptiGO models and the rear
wheel on Arc models are attached to the bike by
quick release clamping systems. It is critical to
use these systems properly when attaching a wheel
to your bike. Before attaching or removing a wheel that
includes a quick release clamping system, you should
closely read the section above entitled Quick Release
Clamping Systems.
WARNING! An improperly adjusted quick release can allow
the front or rear wheel to become loose or detach from the
bike. If a wheel detaches from the bike while you are riding
it, you will lose control and suffer a serious injury or be killed.
IT IS CRITICAL THAT YOU UNDERSTAND HOW TO OPERATE
THE QUICK RELEASE LEVERS AND THAT YOU CHECK THE
SECURITY OF EACH QUICK RELEASE SYSTEM EVERY TIME
YOU RIDE THE BIKE.
