QUICK RELEASE SETUP
The seat post clamp works exactly like the traditional wheel clamp
fastener. The binder uses an over-center cam action to firmly clamp the
seat post
Riding with an improperly tightened seat post can allow the saddle to turn
or move and cause you to lose control and fall. Before you ride your
Hummingbird, make sure you check that the seat post is securely clamped.
ADJUSTING THE SEAT POST
CL AMP MECHANISM
The action of the cam squeezes the seat collar around the seat
post to hold the seat post securely in place. The amount of
clamping force is controlled by the tension adjusting nut.
Increase clamping by changing the tension - adjust the nut
clockwise, while keeping the cam lever from rotating.
Turning it counterclockwise while keeping the cam lever from
rotating reduces clamping force. Less than half a turn of the
tension adjusting nut can make the difference between safe and
unsafe clamping force.
T YRES
Never inflate a tyre beyond the maximum pressure marked on the tyre’s
sidewall. Exceeding the recommended maximum pressure may blow the
tyre off the rim, which could cause damage to the bike and injury to the
rider.
You can inflate the tyres with the Hummingbird pump supplied with the
bike, but we reccomend getting a floor pump with a pressure indicator
dial for home use.
The Presta valve has a narrower diameter and it is designed to hold
higher pressure. To inflate a Presta valve tube using a Presta headed
bicycle pump, remove the valve cap; unscrew (counterclockwise) the
valve stem lock nut and push down on the valve stem to free it up. Then
push the pump head on to the valve head and inflate.
Do not begin any adjustments or service on your Hummingbird unless
you have been guided by a specialised technician. We recommend that
significant mechanical repairs should be carried out by a qualified bicycle
mechanic. Improper adjustment or service may result in damage to the
bicycle or in an accident which can cause serious injury.

WHEEL QUICK RELEASE SETUP
The wheel hub is clamped in place by the force of the over-center cam
pushing against one dropout and pulling the tension adjusting nut, by
way of the skewer, against the other dropout. The amount of clamping
force is controlled by the tension adjusting nut.
