3.2 OHM FRAME FIT
As your OHM bicycle does not have a top tube you may also use the
seat tube measurement to determine proper fi t. The seat tube length
designation is measured as the length from the middle of the bottom
bracket to the top of the seat tube. For example, if you rode a 19”
bicycle in the past, you may also consider a 19” OHM frame.
Have your dealer assist you in fi nding the ideal frame for your size,
riding style and experience.
3.3 SADDLE POSITION
It is very important that
your saddle position is set
according to your personal
preference to ensure
maximum performance and
comfort while riding your
bike. If you fi nd that the
saddle is not comfortable,
ask your dealer to assist you
in making any adjustments.
He/she will have the
necessary tools and skills
required for the adjustment.
The saddle can be adjusted
in three directions:
1 > Up and down adjustments. To check for the correct saddle
height (see Fig 3.3a):
• sit on the saddle;
• place one heel on a pedal;
• rotate the crank until the pedal with your heel on it is in the down
position and the crank arm is parallel to the seat tube.
Evaluation: if your leg is not completely
straight (but not locked) and just touching
the centre of the pedal, your saddle needs
to be adjusted. If your hips have to rock for
the heel to reach the pedal, the saddle is
too high. If your knees are obviously bent
with your heel on the pedal, your saddle
is too low. When you have ensured the
saddle is set to the correct height, make
sure that the seat post does not exceed the minimum insertion or
maximum extension (see Fig 3.3b). There will be a line or marking on
the seat post indicating the point at which you cannot extend the post
before it is unsafe.
WARNING: A mounted seat post that exceeds the
allowable Minimum Insertion or Maximum Extension mark
(see Fig 3.3b) can cause injury and/or for you to lose control
of your bike and/or damage your bicycle.
