ADJUSTMENTS & USAGE GUIDE
ADJUSTING THE BALANCE
In order to achieve a smooth and comfortable ride 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 base levelers located beneath the front and rear
bases. To do so, use Spanner (No. 77) to loosen the Nut
(No. 49)by turning it clockwise (direction A). With the nut
loosened, rotate the Base Leveler (No. 16)until it sits level
with the surface that the bike is on. When you have finished
adjusting the base leveler, re-tighten the Nut (No. 49)by
turning it counter-clockwise (direction B) using Spanner (No.
77). If required, repeat this process to adjust the remaining
base levelers.
RESISTANCE AND BRAKING
You may adjust the tension level of the bike by rotating the
Tension Knob (No. 11). To increase the level of resistance,
rotate the tension knob clockwise, to decrease the level of
resistance, rotate the tension knob counter-clockwise.
During exercise, you may stop the bike immediately by
pushing down on the Brake-Handle (No. 9). This is the
emergency brake.
PEDAL STRAP ADJUSTMENT
Your feet should be secured in the toe clips during exercise.
Place your feet as far forward into the toe-clips as you can.
With your feet in place, turn the crank to bring one foot to
within arm’s reach, grasp the pedal strap and pull it upward
to tighten the toe-clip cage, then insert the strap back into
the hoop of the toe-clip. Repeat this process to secure your
other foot.
TRANSPORTING THE BIKE
To move the bike, first ensure that the Handlebar (No. 5) is
properly secured. If the handlebar is loose, tighten the Pop
Pin (No. 23)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 base and tilt the bike towards you until the transport
wheels on the front base 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.

10
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 (No. 2), loosen and
pull the [seat post] Pop Pin (No. 23)outward, then raise or
lower the seat to the desired height. Once adjusted, re-insert
and tighten the [seat post] Pop Pin (No. 23)to secure the
seat in place.
To adjust the seat back and forth, loosen and pull [seat
slider] Pop Pin (No. 23) outward, then slide the Seat Slider
(No. 3) to the desired position. Once positioned, re-insert
and tighten the [seat slider] Pop Pin (No. 23) to secure the
seat slider tube in place.
ADJUSTING THE HANDLEBAR
It is important that the handlebar and seat are both set to the
correct height of your body. To adjust the handlebar height,
loosen and pull the Pop Pin (No. 23) outward, then slide the
Handlebar Post (No. 4) up or down to the desired height.
Once adjusted re-insert and tighten the Pop Pin (No. 23) to
secure the handlebar post in place.
CHECKING BRAKE PADS AND PEDALS
Ensure all the Nuts, Nut Caps and Pedals are secured and
inspect the equipment regularly. If you should find any
defective parts, do not exercise until they’ve been repaired.
Pay close attention to easily damaged parts due to wear and
tear. Please inspect Brake Pads (No. 41) to ensure there is
still adequate padding on each side before exercising. Make
sure to replace brake pads as necessary. Also, inspect the
Pedals before exercise. If they have become loose, please
re-tighten.
TIGHTENING THE SEAT
Please adjust the Hexagon Nuts by using the Wrench (No.
75)if the Seat (No. 22) is loose.
NOTE: In order to properly tighten the seat, it is important to
note that you will need two open faced wrenches (1 for each
side) and will need to tighten the nut on each side
simultaneously working in opposite direction of each other.

MAINTENANCE INSTRUCTIONS
This is general information for daily, weekly and monthly maintenance to be performed on your bike.
Version 3.1
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.
