ADJUSTING THE HEIGHT 

 
Loosen and pull out the [seat height] 

Adjustment Knob (No. 13) 

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. 13) 

on the

 

Seat Slider (No. 16). 

You may adjust the height of the handlebar by using 

the [handlebar]

 Adjustment Knob (No. 13). 

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 Knob (No. 

13)

  to ensure that they are fully secure when you finish making an 

adjustment. 

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. 13) 

to secure it. Next, 

stand at the front of the bike so that you’re directly in front of the handlebar. 
Firmly grab and hold each side of the 

Handlebar (No. 5)

, 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 ANGLE OF SEAT 

 
Use 

Spanner  (No. 33)

  to unscrew the nut under the saddle. Adjust the 

saddle to the desired angle and re-install and secure the nut. Check the nut 
periodically to ensure that it is tight and secure. Use the 

Spanner (No. 33) 

to tighten when necessary. 
Note: In order to properly tighten the seat, it is important to note that you will 
need two 

Spanner (No. 33)

 (1 for each side) and will need to tighten the nut 

on each side simultaneously working in opposite direction of each other. 

ADJUSTING THE TENSION & EMERGENCY STOP 

 
Adjusting tension by rotating the

  Tension Knob (No. 51)

  clockwise to 

increase the level of resistance. Rotate the knob counter-clockwise to 
decrease the level of resistance. Push down on 

Tension Knob (No. 51)

 to 

enforce the brake and stop the bike immediately. 

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 end caps located on the rear stabilizer. To do so, 
simply rotate the 

End Caps (No. 28) 

located on the 

Rear Stabilizer (No. 29)

 

until the bike becomes level with the floor surface.
