Forks
There are two different types of forks that range in styles and dimensions.
One type is a rigid fork (Figure 1) consisting of stationary tubing with
curved blades. The other type is a suspension fork (Figure 2) consisting
of stanchion tubes riding on elastomers or springs inside of a straight fork
leg. This mechanism acts as a shock absorber with a specified amount
of travel that varies between models. Some suspension forks are not
adjustable and are very difficult to disassemble. If service is needed on a
suspension fork, consult a professional bicycle repair technician.
Do not attempt to disassemble a suspension fork yourself.
Consult a professional bicycle repair technician.
Check the tightness of the headset and the fork. Rotate the fork checking
for smoothness. If it feels like the fork is binding, then an adjustment will
need to be made to the headset. Move the fork in a push/pull manner
checking for tightness. If any play is detected, loosen the top nut,
adjust the bearing cup, and retighten the top nut. Recheck the rotation
and tightness. If necessary, readjust until a smooth rotation is achieved
without backward or forward movement. If your bike is equipped with a
suspension fork, check that the fork compresses and rebounds smoothly.
To do this, place the fork dropouts against the ground, push and release
the handlebar. The fork will generally compress 1-2” and rebound quickly.
Most elastomer type forks will gradually soften with use.

Seat and Seat Post
Attach the seat to the seat post by inserting the smaller end of the seat post
into the seat clamp and tighten. Insert the larger end of the seat post into
the seat tube of the bicycle frame observing the minimum insertion mark on
the seat post. Turn the adjusting nut of the Quick Release seat bolt to ensure
the locking lever is moved to the closed position with a firm action. Turn the
bicycle upside down and rest in on the seat and handlebars.
NOTE: Comfort bicycles may be equipped with a suspension seat post (See
Diagram-bottom left). Some suspension posts can be adjusted for stiffness
using the preload adjusting screw. Turning the 6mm Allen screw Clockwise
will decrease travel and make the suspension stiffer, while turning the
6mm Allen screw Counter-clockwise will increase travel and make the
suspension less rigid.
Note: In addition to normal assembly, please be aware that the preload
adjusting screw must be flush with the bottom of the post.
Failure to do this may cause irreparable damage.
The seat post must be inserted so that the minimum
insertion mark cannot be seen. The quick release
mechanism must be tightened securely to prevent a sudden
shift of the seat when riding Failure to do this may cause
loss of bicycle control.
