ADJUSTING THE HEIGHT AND 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 of the bike. To do
so, use Spanner (No. 80) to loosen 2 Nuts (No. 48) by turning it
clockwise (direction A). With the nut loosened, rotate the Foot
Leveler (No. 15) until it sits level with the surface that the bike is
on. When you have finished adjusting the foot leveler, use
Spanner (No. 80) to re-tighten the 2 Nuts (No. 48) by turning it
counter-clockwise (direction B). If required, repeat this process to
adjust the remaining foot levelers.
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
Adjustment Knob (No. 16) outward, then raise or lower the seat
to the desired height. Once adjusted, re-insert and tighten the
Adjustment Knob (No. 16) to secure the seat in place.
To adjust the seat back and forth, loosen and pull Adjustment
Knob (No. 16) outward, then slide the Seat Slider Tube (No. 8) to
the desired position. Once positioned, re-insert and tighten the
Adjustment Knob (No. 16) 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 Adjustment Knob (No. 16) outward, then slide the
Handlebar Post (No. 4) up or down to the desired height. Once
adjusted re-insert and tighten the Adjustment Knob (No. 16) to
secure the handlebar post in place.
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.

8
ADJUSTING THE RESISTANCE
Adjust the resistance of the bike using the Tension Knob (No.
47). 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).
EMERGENCY BRAKE
During use, users can stop the bike completely by pushing down
on the Tension Knob (No. 47). Pushing down on the tension
knob will enforce the brake and bring the bike to an immediate
stop.
TRANSPORTING THE BIKE
To move the bike, first ensure that the Handlebar (No. 3) is
properly secured. If the handlebar is loose, tighten the
Adjustment Knob (No. 16) 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.
NOTE: When moving the bike, always use caution as
unexpected impact, such as dropping the bike, may cause injury
and affect the bike’s performance.
DISMOUNTING
For your safety, it is recommended that you never attempt to dismount or remove your feet from the
pedals until both the flywheel and pedals/crank have come to a complete stop. Failure to follow this
recommendation may lead to loss of control and/or serious injury.
Here are a few examples of how to safely dismount the bike:
1. Reduce the pedal speed until the pedals/crank come to a complete stop.
2. Increase the resistance until the pedals/crank come to a complete stop.
3. Push and hold the tension knob down until the pedals/crank come to a complete stop.

MAINTENANCE INSTRUCTIONS
This is general information for daily, weekly and monthly maintenance to be performed on your bike.
Version 4.1
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 chain/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, 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.
