ADJUSTMENTS GUIDE
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. 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, hold 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.

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 (No. 47) to the RIGHT (clockwise), decrease the level of
resistance by turning the Tension Knob (No. 47) 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 (No. 47) 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.

SPD TECHNICAL SERVICE INSTRUCTIONS
Caution!
Before use, read these instructions carefully.
⚫Practice engaging and disengaging from the pedals several times in a stationary position before
riding.
⚫Before using, lubricate the concave area of the clip.
⚫Keep the cleat and pedal clean to ensure proper usage.
⚫The cleat of our clipless is adaptable for all standard SPD shoes. This cleat allows for a 4 degree
lateral foot rotation, just enough to relieve knee stress.
⚫Before using, adjust the retention force of the pedal to suit your needs.
INSTALLING THE CLEATS
1. Remove the pad from the shoe using a pair of pliers.
2. Remove the sockliner and install the cleat set according to the following illustration. Then,secure
the cleat tightly with the bolt using Allen Wrench.

Note:
1. The cleat has an adjustment range of 5 mm right to left. After tightening the cleat, practice engaging
and releasing one shoe at a time. Readjust to determine the best cleat position. After you have
determined the best cleat position, firmly tighten the cleat mounting bolts with a 4 mm AllenWrench
2. Check your pedals everytime before you ride the bike.
3. When the pedal starts to wear on the axle, it will not function properly. We recommend you replace
the entire pedal.
USE
Engaging Disengaging
Press the cleat into the pedal. Remove by twisting your heel to the outside.
ADJUSTING THE SPRING TENSION OF THE BINDING
The tension of the spring is adjusted for each pedal (top & bottom) with the adjustment bolt in the rear
using 3mm Allen Wrench.
Turn the bolt using 3mm Allen Wrench in a clockwise direction to increase retention force, and in a
counter-clockwise direction to decrease retention force.

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 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 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 secured. 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.
