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 of the bike. To do so, use
Spanner (No. 76)to loosen Nut (No. 13)by turning it clockwise
(direction A). With the nut loosened, rotate the Foot Leveler (No.
64) until it sits level with the surface that the bike is on. When you
have finished adjusting the foot leveler, use Spanner (No. 76)to
re-tighten the Nut (No. 13) by turning it counter-clockwise (direction
B). If required, repeat this process to adjust the remaining feet.
ADJUSTING THE RESISTANCE
Adjust the resistance of the bike using the Tension Knob (No. 12).
Increase the level of resistance by turning the Tension Knob (No.
12)to the RIGHT (clockwise), decrease the level of resistance by
turning the Tension Knob (No. 12)to the LEFT (counter-clockwise).
Push down on the Tension Knob (No. 12)for the emergency brake.
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.
Loosen the [seat adjustment] Knob (No. 11)to raise or lower Seat
Post (No. 7) to the desired position. Make sure Knob (No. 11)
secures into the desired hole.
Loosen L-shaped Knob (No. 5) to move the seat forward or
backward to the desired position. Once the position is located,
firmly secure L-shaped Knob(No. 5) by turning clockwise.

ADJUSTING THE HANDLEBAR
Loosen the [handlebar adjustment] Knob (No. 11)to raise or lower
the handlebar to the desired position. Make sure the Knob (No. 11)
settles into the desired hole and secure it firmly by turning
clockwise. See Figure A.
Loosen the L-shaped Knob (No. 5) to move the handlebar forward
or backward to the desired position. Once the handlebar is in the
desired position, firmly secure the L-shaped Knob (No. 5) by
turning clockwise. See Figure B.
ADJUSTING THE PEDAL STRAP
Place the ball of each foot in the toe clips so the front of your shoe
fits securely 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
securely. Insert the strap back into the hoop of the toe clip.
Repeat this process for the other foot.
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 Tension Knob (No. 12).
MOVING THE BIKE
To move the bike, first ensure that the handlebar is properly
secured. If the handlebar is loose, tighten the Knob (No. 11)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.
Version 3.5
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 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 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 secure. 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. 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.
