ADJUSTMENT GUIDE

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.
7

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, 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.
