ADJUSTMENT GUIDE
ADJUSTING THE TENSION & EMERGENCY STOP:
Adjust the tension by rotating the knob clockwise to increase
the resistance. Rotate the knob counter- clockwise to decrease
the resistance.
Push down the knob to enforce brake, and stop the bike
immediately.
ADJUSTING THE BALANCE:
In order to achieve a smooth and comfortable exercise during
use, you must ensure that the stability of the bike is correct. If
during use you notice that the bike is unbalanced you can adjust
the foot pads located beneath the front and rear stabilizers. To
do so, rotate the Foot Pad (No. 13) by hand until it sits level
with the surface that the bike is on. To raise the foot pad, turn it
counter-clockwise; to lower the foot pad, turn it clockwise. When
you have finished adjusting the food pad, re-tighten the
Hexagon Nut (No. 82) by turning it counter-clockwise using
Spanner (No. 85). If required, repeat this process to adjust the
remaining foot pads.
ADJUSTING THE SEAT:
The seat of this bike is fully adjustable as it moves Up, Down,
Fore (forward), Aft (backward).
To adjust the height of the Seat Post, loosen and pull the
Adjustment Knob (No. 10) outward, then raise or lower the
seat to the desired height. Once adjusted, re-insert and tighten
the Adjustment Knob (No. 10) to secure the seat in place.
To adjust the seat back and forth, loosen and pull Adjustment
Knob (No. 30) outward, then slide the Seat Slider to the desired
position. Once positioned, re-insert and tighten the Adjustment
Knob (No. 30) to secure the seat slider tube in place.

10
TRANSPORTING THE BIKE
To move the bike, first 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 transport 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.
NOTE: When moving the bike, always move with caution as unexpected impact, such as
dropping the bike, may cause injury and affect the bike’s operation.

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.
