Footplates and Foot Position
The position of the foot on the pedal is an important factor in
transferring leg muscle action into pedal power. This requires the
arch of the foot to be over the centre of the pedal where the most
force can be applied. Using the 10mm spanner provided, loosen the
nuts on the underside of the footplate to slide the plate backwards
and forwards to achieve the best position. Ensure the nuts are tight
before using the trike.
!
For safety, footplates must always be
used in conjunction with a hip support.
Fitting Crank Shorteners
Crank shorteners move the pedals closer to the centre of pedal
rotation. This helps position users with short legs and prevents legs
going into either full extension (straight) or full exion (bent at knee).
The cycling action is thus made smoother and easier for the user to
control. Crank shorteners are made in left and right hand pairs. Fit
them one side at a time.
1 Remove the left hand pedal from the pedal crank. Ensure you
are tting the left hand crank shortener by turning the bolt marked
with an 'L' anticlockwise into one of the threaded holes in the crank
shortener. If it does not turn in easily, try the other crank shortener.
2 Once you have selected the left hand crank shortener, hold it
on the crank with the small guides on the shortener tting over the
crank and the hole with no thread in line with the hole on the end
of the crank.
3 Insert the bolt marked 'L' through the end of the crank shortener
and turn it anti-clockwise into the hole at the end of the crank. Ensure
the bolt is rmly tightened.
4 Once in place t the pedal into one of the settings in the crank
shortener, paying attention to the action of the user's leg (see section
'Saddle Height').
Repeat the process for the right hand crank shortener, bearing in mind
that the pedals will undo anti-clockwise and tighten up clockwise.
