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 the Wrench (No. 88) to loosen Hex Nut (No. 6) by
turning it clockwise (direction A). With the screw loosened,
rotate Adjusting Pad (No. 5) until it sits level with the surface
that the bike is on. When you have finished adjusting the foot
leveler, use the Wrench (No. 88) to re-tighten the Hex Nut
(No. 6) by turning it counter-clockwise (direction B). If required,
repeat this process to adjust the remaining feet.
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.
Dismount the bike before adjusting the seat.
Loosen the [seat adjustment] Spring Knob (No. 13)to raise or
lower Seat Post (No. 18) to the desired position. Make sure
Spring Knob (No. 13)secures into the desired hole.
Loosen Spring Knob (No. 13) to move the seat forward or
backward to the desired position. Once the position is located,
firmly secure Spring Knob (No. 13)by turning clockwise.
Figure A
ADJUSTING THE RESISTANCE
Adjust the resistance of the bike using the Brake Handle (No.
16). Increase the level of resistance by pressing the Brake
Handle (No. 16) downward, decrease the level of resistance
by pressing the Brake Handle (No. 16) upward. Push down on
the Brake Handle (No. 16)for emergency brake.

11
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 Brake Handle
(No. 16).
Figure B
ADJUSTING THE HANDLEBAR
Loosen the [handlebar adjustment] Spring Knob (No. 13)to
raise or lower the handlebar to the desired position. Make sure
the Spring Knob (No. 13) settles into the desired hole and
secure it firmly by turning clockwise.
Loosen Triangle Knob (No. 26) to move the handlebar forward
or backward to desired position. Tighten the Triangle Knob
(No. 26) to secure.
ADJUSTING THE PEDAL STRAP
Place the ball of each foot in the toe clips so the front of your
shoe fits snugly 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 snugly. 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.
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 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, making
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, making 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.
