Assemble the left crankarm onto the bottom bracket spindle using an 8mm hex key and torque as shown. The left
crank arm will press against the bottom bracket with no gap. Check the assembly for play by pulling the crankarm
away from the boom, alternating back and forth. If the crank moves, tighten crankarm bolt until no play is detected.
If maximum torque has been reached, remove the crankarm from the spindle, apply additional grease, and repeat the
installation. It may take several installations to eliminate all play.
Note: the seals on the bottom bracket are designed to prevent contamination and
therefore must rub against their sealing surfaces. New seals will feel stiff when they are
first installed. This is normal. With use the seals will wear in and loosen up.
Warning: if you do not follow the instructions for installing the bottom bracket exactly,
then within a few miles the bottom bracket will develop play. It will feel much the same
as a bottom bracket with a bad or worn bearing. If this happens soon after you begin to
use the bike, retighten the bottom bracket.
2.7 Fit the pedals
(Your own if not ordered from us) – Note: the pedal threads are handed. The right hand pedal tightens in the
normal direction; the left-hand pedal has a left hand thread, and tightens in the opposite direction to normal.
Tighten the pedals to the torque shown in section 2.10
2.8 Adjust the seat angle
Sit on the bike (see section 5.1) and decide whether the seat angle suits you. The seat can be set more upright
(it was set to maximum recline in section 2.8) by simply opening the seat mount quick-release, sliding the seat
mount off the quick-release, and slotting it back over using a different set of slots. Please refer to section 3.4.
You may find a more upright position is initially better until you learn how the bike handles.
Do not use the handlebars to pull yourself out of the seat; they are not meant for
this purpose. Under normal use the handlebars will not slip in their clamps, they
will however move if subjected to an abnormal force.
There is also no need to pull on the handlebars when riding. The bike is easily
steered with a light grip of the fingers.
2.9 Set the front boom
Set the leg length by sitting on the bike and placing your heel on the pedal. Adjust the boom so that your leg is
almost straight when the pedal is at its furthest away from you. Set the front boom upright (by eye), and then
tighten the 2 clamp bolts.
Check the boom is not extended past its minimum insertion length. The end of the boom should not be visible in
the slot in the underside of the frame.
Obviously, this is a picture of a
trike, however, the principle is the
same.
As you won’t have the benefit of 3
wheels, you may need someone to
help hold you and the bike upright
while you check the boom length.
If you are doing this on your own,
try leaning against a wall while
checking the length. It’s important
that you are leaning back in the
seat in a proper riding position
when you are checking this
measurement.
2.10 Set the handlebars
The handlebars on your bike may need a small amount of adjustment. The main reason for adjusting the
handlebars is to ensure that you are comfortable and have adequate room for your knees when pedalling. The is
no ‘correct’ position, the best position is one that feels right to you.
