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 (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. Once you finish 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.

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. 5), loosen and pull the [seat] Height Adjustment
Knob (No. 10)outward, then raise or lower the saddle to the desired height. Once adjusted,
re-insert and tighten the Height Adjustment Knob (No. 10)to secure the saddle in place.
To adjust the saddle back and forth, loosen and pull Seat Adjustment Knob (No. 9) outward,
then slide the Seat Slider Tube (No. 4) to the desired position. Once positioned, re-insert and
tighten the Seat Adjustment Knob (No. 9) to secure the seat in place.
10
ADJUSTING THE HANDLEBAR
It is important that the handlebar and seat are both set to the correct height to your body. To adjust
the handlebar height, loosen and pull the [handlebar] Height Adjustment Knob (No. 10) outward,
then slide the Handlebar (No. 1) up or down to the desired height. Once adjusted, re-insert and
tighten the Height Adjustment Knob (No. 10) to secure the handlebar in place.
11

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
then grasp the pedal strap and pull it upward to tighten the toe-clip cage. 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. 73). 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).
12

MOVING THE BIKE & BRAKING/DISMOUNTING
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] Height Adjustment Knob (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 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. 73).
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.
