ADJUSTMENTS GUIDE

ADJUSTING THE BALANCE
In order to achieve a smooth and comfortable ride, you must
ensure that the stability of the bike is secured. If you notice
that the bike is unbalanced during use, you should adjust the
foot levelers located beneath the front and rear stabilizers. To
do so, use Spanner (No. 76) to loosen Nut (No. 42) by turning
it clockwise (direction A). With the nut loosened, rotate Foot
Levelers (No. 3) until it sits level with the surface that the bike
is on. When you have finished adjusting the foot leveler, use
Spanner (No. 76) to re-tighten the Nut (No. 42) by turning it
counter-clockwise (direction B). If required, repeat this process
to adjust the remaining feet.
ADJUSTING THE RESISTANCE
Adjust the resistance of the bike using the Tension Knob (No.
41). Increase the level of resistance by turning the tension
knob to the RIGHT (clockwise), decrease the level of
resistance by turning the tension knob to the LEFT (counter-
clockwise). Push down on the Tension Knob (No. 41) for
emergency brake.
ADJUSTING THE SEAT
An appropriate seat height helps to ensure your exercise
efficiency and reduce the risk of injury. Adjusting the seat
forward or backward can help you work out different body
muscle groups.
With one pedal in the upward position, place your foot in the
toe clip and get on the bike. If your leg is bent too much, you
should move the seat up. If your foot cannot touch the pedal
or your leg is too straight, you should move the seat down.
Loosen the [seat adjustment] Knob (No. 38) to raise or lower
Seat Post (No. 30) to the desired position. Make sure Knob
(No. 38) secures into the desired hole.
Loosen L-Shaped Knob (No. 29) to move the seat forward or
backward to the desired position. Once the position is located,
firmly secure L-Shaped Knob (No. 29) by turning clockwise.

8
DISMOUNTING THE BIKE
WARNING! Do not dismount the bike or remove your feet
from the pedals until the pedals have stopped completely.
You can stop the flywheel at anytime by pushing down on
Tension Knob (No. 41).
Figure A
Figure B
ADJUSTING THE HANDLEBAR
Loosen the [handlebar adjustment] Knob (No. 38) to raise or
lower the handlebar to the desired position. Make sure the
Knob (No. 38) settles into the desired hole and secure it
firmly by turning clockwise. See Figure A.
Loosen the L-Shaped Knob (No. 29) to move the handlebar
forward or backward to the desired position. Once the
handlebar is in the desired position, firmly secure the L-
Shaped Knob (No. 29) by turning clockwise. See Figure B.
ADJUSTING THE PEDAL STRAP
Place the ball of each foot in the toe clips so the front of your
shoe fits snuggly in the toe clip cage. Rotate one foot to
within arm’s reach and pull the strap until the top clip cage
fits your shoe snuggly. Insert the strap back into the hoop of
the toe clip. Repeat this for the other foot.
MOVING THE BIKE
To move the bike, first ensure that the handlebar is properly
secured. If the handlebar is loose, tighten the Knob to
secure it. Next, stand at the front of the bike so that you’re
directly in front of the handlebar. Firmly grasp and hold each
side of the handlebar, place one foot on the front stabilizer
and tilt the bike towards you until the transportation wheels
on the front stabilizer touch the ground. With the wheels on
the ground, you can transport the bike to the desired location
with ease.

MAINTENANCE INSTRUCTIONS
This is general information for daily, weekly and monthly maintenance to be performed on your bike.
13
Version 4.3
DAILY MAINTENANCE
After each exercise session, wipe down all
the equipment: seat, frame, handlebars. Pay
special attention to the seat post, handlebar
post and belt/chain guard. Sweat is very
corrosive and may cause problems that
require parts replacement later.
1. Get on the bike and engage the drive
train.
2. Pay attention to any vibrations felt
through the pedals. If you feel any
vibrations, you may need to tighten the
pedals, bottom bracket, or adjust the drive
belt/chain tension.
3. Use a wrench to tighten the pedals until
they are secure.
MONTHLY MAINTENANCE
1. Check if all hardware is secure, such as:
water bottle holder, flywheel nuts, belt/chain
guard bolts, brake caliper lock nuts and
brake caliper tension rod nuts.
2. Inspect the brake tension rod for signs of
wear such as missing threads. Clean and
lubricate the brake tension rod.
3. Clean and lubricate the seat post, handlebar
post and seat slider. Remove any build up of
foreign material.
WEEKLY MAINTENANCE
1. Inspect moving parts and tighten the
hardware.
2. Inspect pull pin frame fittings to make
sure the fittings are snug. Loose frame
fittings may strip out threads over time
and cause extensive damage.
3. Clean and lubricate pop pin assemblies.
Pull on the pin and spray a small amount
of lubricant onto the shaft.
4. Tighten the seat hardware to make sure
the seat is level and centered.
5. Brush and treat the resistance pads.
Remove any foreign material that may
have collected on the pads. Spray the
pads with silicone lubricant. This helps to
reduce noise from friction between the
pads and the flywheel.
6. Visually inspect the bottom bracket, toe
clips and toe straps. If any of them are
loose or disconnected, attach and
tighten..
LEATHER BRAKE PAD CARE (If Applicable)
1. Perform this maintenance when the brake
pad is first installed and for the life of the
brake pad. Following these simple guidelines
can increase the life of your brake pads.
2. Some brake pad assemblies are pre-
lubricated. Squeeze the brake pad. If
lubricant is released, then the pad has been
pre-lubricated.
3. If the brake pad is dry, then coat the brake
pad with 3-n-1 oil. Brush the leather with a
clean, wire bristle brush, and then apply the
oil. The oil should be allowed to soak in to
the pad. Repeat 4-5 times until the pad is
saturated, but not dripping with oil. When the
pad is saturated, it will no longer absorb oil.
4. Inspect the brake pad weekly and lubricate if
needed. The pad should not have a glazed
appearance. If the pad appears glazed, then
brush it with wire brush and apply lubricant
as needed. If any of the sponge padding is
showing through the leather pad, the brake
pad should be replaced.
