ADJUSMENTS 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 Nut (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 Nut (No. 48) by
turning it counter-clockwise (direction B). If required, repeat this process to adjust the
remaining foot levelers.

ADJUSTING THE SADDLE
The seat of this bike is fully adjustable as it moves Up, Down, Fore (forward), Aft (backward).
To adjust the height of the Saddle Post (No. 2), loosen and pull the Adjustment Knob (No.
16) outward, then raise or lower the saddle to the desired height. Once adjusted, re-insert and
tighten the Adjustment Knob (No. 16) to secure the saddle in place.
To adjust the saddle 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.
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).

11
MOVING THE BIKE & BRAKING/DISMOUNTING
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 move with caution as unexpected impact, such as
dropping the bike, may cause injury and affect the bike’s operation.
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.
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.
