Step 1
1. Install the front stabilizer (41) with 2 carriage bolts(52), curved washers (53) and acorn nuts
(51) by using the hand tools. Make sure the transportation wheels are in correct direction.
2. Assemble the Rear Stabilizer (39) with 2 carriage bolts(52), curved washers (53) and acorn
nuts (51) by using the hand tools. Adjust the end caps on the rear stabilizer to set up a
stable, balanced position.
After assembling the bike, you can adjust to slightly uneven ground by adjusting the height of
the foot caps (40) in the back. The pre-assembled transportation wheels in the front allow
easy movement of the bike: The transportation-wheels need to point downwards and to the
front.
Step2
1. Assemble the straps onto the pedals as the sketches. Adjust the ideal length of the straps
according to your foot size.
2. Assemble the two pedals (31 L/R) onto the crank (5) with a screw driver.
Remarks: screw the left pedal’s spindle counter-clockwise and the right pedal’s spindle
clockwise. Use a wrench (or screwdriver) to screw the two spindles completely.

3. Insert the seat post (45) into the main frame, then choose the desired position and tighten
the knob. Be sure the seat knob (22) is always securely fastened.

Step 4
1. Pull the upper tension control (36) of the handlebar post (34) and ensure the tension knob
is at the lightest position (minimum position)
2. Connect the upper tension control (36) and down tension control (32), then connect
the upper sensor wire (35) and down sensor wire (25).
3. Slide the Handlebar post (34) into the Main frame (21) then fix it with four sets of
M8*P1.25*16L Allen bolt (19) and semicircle washers (53).
Remarks: Do not screw one set of the M8*P1.25*16L Allen bolt and semicircle washers too
firm at one time. It is better to fix the four sets firmly at the same time because it helps you to
change angles and to fix more easily.
