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, adjust the
Adjustment Foot Pad (No. 37), located beneath the
Front & Rear Stabilizers (No. 5 & No. 6) of the bike. To
do so, use Wrench (No. 96) to loosen Hex Thin Nut (No.
76) by turning it clockwise (direction A). With the nut
loosened, rotate the Adjustment Foot Pad (No. 37) until
it sits level with the surface that the bike is on. When you
have finished adjusting the Adjustment Foot Pad (No.
37), re-tighten the Hex Thin Nut (No. 76) by turning it
counter-clockwise (direction B) to complete the balance
adjustment of the bike. If needed, repeat this process to
adjust the remaining adjustment foot pad.

ADJUSTING THE RESISTANCE
Adjust the resistance of the bike using the Tension
Control Knob (No. 21). Increase the level of resistance
by turning the Tension Control Knob (No. 21) to the
RIGHT (clockwise), decrease the level of resistance by
turning the Tension Control Knob (No. 21) to the LEFT
(counter-clockwise).
EMERGENCY BRAKE
During use, users can stop the bike completely by pushing
down on the Tension Control Knob (No. 21). Pushing
down on the Tension Control Knob (No. 21) will enforce
the brake and bring the bike to an immediate stop.

To adjust the seat back and forth, loosen and pull the
Adjustment Knob (No. 22) outward, then slide the Seat
