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 (No. 20) located beneath the Front and Rear Stabilizers
(No. 16 & No. 29) of the bike. To do so, use Spanner (No. 33)to
loosen Nut (No. 19)by turning it clockwise (direction A). With the
nut loosened, rotate the Foot Leveler (No. 20)until it sits level with
the surface that the bike is on. When you have finished adjusting
the foot leveler, use Spanner (No. 33)to re-tighten the Nut (No.
19)by turning it counter-clockwise (direction B). If required, repeat
this process to adjust the remaining foot levelers.

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. 1) is
properly secured. If the handlebar is loose, tighten the [handlebar] T
Shape Knob 2 (No. 10) 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 operation.
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 control 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
Allen Wrench
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

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 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 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.
