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 Seat Post (No. 4), loosen and
pull the Adjustment Knob (No. 14) outward, then
raise or lower the seat to the desired height. Once
adjusted, reinsert and tighten the Adjustment Knob
(No. 14) to secure the Seat Post (No. 4) in place.
To adjust the seat back and forth, loosen the
Adjustment Knob (No. 15), then slide the Seat
Slider (No. 7) to desired position. Once positioned,
re-tighten the Adjustment Knob (No. 15) to secure
the Seat Slider (No. 7) in place. There are 2 holes
on the Seat Slider (No. 7) to make the adjustment
range larger. If the adjustment range for the current
hole is not enough, please remove the Adjustment
Knob (No. 15)and Flat Washer (No. 19) from Seat
Slider (No. 7), then attach Adjustment Knob (No.
15)and Flat Washer (No. 19) to the other hole on
the Seat Slider (No. 7) and retry it. Once positioned,
re-tighten the Adjustment Knob (No. 15) to secure
the Seat Slider (No. 7) in place.
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, adjust the Adjustment Foot Pad (No.
28), located beneath the stabilizers of the bike.
ADJUSTING THE RESISTANCE
Adjust the resistance of the bike using the Tension
Control Knob (No. 30). Increase the level of
resistance by turning the Tension Control Knob
(No. 30) to the RIGHT (clockwise), decrease the level
of resistance by turning the Tension Control Knob
(No. 30) to the LEFT (counter-clockwise).
EMERGENCY BRAKE
During use, users can stop the bike completely by
pushing down on the Tension Control Knob (No.
30). Pushing down on the Tension Control Knob
(No. 30) will enforce the brake and bring the bike to
an immediate stop. When the Tension Control
Knob (No. 30) is tightened, the flywheel can be
locked.

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/cranks 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/cranks come to a complete stop.
2. Increase the resistance until the pedals/cranks come to a complete stop.
3. Push and hold the tension control knob down until the pedals/cranks come to a complete
stop.
TRANSPORTING THE BIKE
To move the bike, first ensure that the Handlebar
(No. 6) is properly secured. If the Handlebar (No.
6) is loose, tighten the Adjustment Knob (No.
14) to secure it. Next, stand at the front of the
bike so that you’re directly in front of the
Handlebar (No. 6). Firmly grasp and hold each
side of the Handlebar (No. 6), place one foot on
the Front Stabilizer (No. 2), and tilt the bike
towards you until the Transportation Wheels
(No. 29) on the Front Stabilizer (No. 2) touch the
ground. With the Transportation Wheels (No.
29) on the ground, you can transport the bike to
the desired location with ease.
NOTE: Always use caution when moving the
bike. Unexpected impact, such as dropping the
bike, may cause injury and affect the bike’s
operation.
ADJUSTING THE HANDLEBAR
It is important that the handlebar and seat are
both set to the correct height to your body.
To adjust the handlebar height, loosen and pull
the Adjustment Knob (No. 14) outward, then
slide the Handlebar Post (No. 5) up or down to
the desired height. Once adjusted, reinsert and
tighten the Adjustment Knob (No. 14) to secure
the handlebar 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.

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, and 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 crank.
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 buildup 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 (not included with product).
Brush the leather with a clean, wire bristle
brush, and then apply the oil. The oil should
be allowed to soak into 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.
