ADJUSTMENTS & USAGE 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. To do so, simply rotate the Foot Leveler (No. 74)
until the bike becomes level with the floor surface.
ADJUSTING THE TENSION & EMERGENCY STOP
Adjust the tension by rotating the Tension Knob (No. 15) clockwise to increase the level of
resistance. Rotate the knob counter-clockwise to decrease the level of resistance. Push down on
Tension Knob (No. 15) to enforce the brake and stop the bike immediately.
12

ADJUSTING THE ANGLE OF SEAT
Use Spanner (No. 91)to unscrew the nut under the saddle. Adjust the saddle to the desired angle
and reinstall the nut. Check the nut periodically to ensure that it is tight and secure. Use the
Spanner (No. 91)to tighten when necessary.
MOVING THE BIKE
To move the bike, first ensure that the handlebar is properly secured. If the handlebar is loose,
tighten the Adjustment Knob (No. 38) 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.
ADJUSTING THE HEIGHT
Loosen and pull out the [seat height] Adjustment Knob (No. 38)to adjust the height of the saddle.
You may also slide the seat forward or backwards by loosening and pulling out the [seat]
Adjustment Knob (No. 38)on the Seat Slider (No. 36). You may adjust the height of the
handlebar by using the [handlebar] Adjustment Knob (No. 38). When making adjustments, you
will see a limit on the saddle post, seat slider and handlebar post. Do NOT lift the posts passed
this mark. Always check the Adjustment Knobs (No. 36)to ensure that they are fully secure when
you finish making an adjustment.
