4 INSTALLATION
Although a competent handyman with the appropriate experience can install your handcycle, we strongly
recommend that a qualified technician, such as a bicycle mechanic or wheelchair dealer, perform the
initial setup and installation of this product.
The primary factor to keep in mind during installation and adjustment of your handcycle is the distance
the cycle raises the wheelchair casters above the ground when in the correct mounted position. In most
cases, this distance should be approximately 5cm (2”). If this distance is much less than 5cm (2”), you
may have difficulties crossing obstacles such as ramps or bumps without touching the wheelchair casters
on the ground and lifting the front wheel off the ground (resulting in a temporary loss of power and
ability to brake). If this distance is much more than 5cm (2”), on the other hand, you may encounter
difficulties rotating the Viper™ into its fully upright position without assistance.
On the other hand if you know that the terrain is going to be fairly flat, the distance of the wheelchair
casters can be lower than 5cm (2”).
