Charge the battery pack following the instructions in the owner’s manual before starting installation.
The letters inside the parts list boxes in the assembly procedures indicate the following:
A: Part in part box 1
B: Part in part box 2
1. Installing the front wheel and fork end
Remove the spacer (b) from the front disc caliper (a). Give the removed spacer (b) to the customer, explaining how it is used.
Align the holes in the front wheel (1) with the holes in the fork end and install the front wheel (1). Install it in such a way that the disc rotor (c) does not touch the disc pad. Put the lever (d) of the front axle (2) down in the direction in which the stamp “OPEN” is visible and check that the collar (e) is open. Install the front axle (2) to the fork end holes from the left side of the bicycle.
-Even if the collar (e) of the front axle (2) is inserted with the collar open, it will close when pressed in.
-When the collar (e) is closed, turn the nut (f) approximately 1/8 turn counterclockwise while keeping it pressed in; the collar will then open.
| No. | Part names | Q'ty | Remarks |
|---|---|---|---|
| (1) | Front wheel | 1 | |
| (2) | Front axle | 1 | B |
Check that the collar (e) of the front axle (2) goes through the hole in the right side of the fork end and that the collar is actually open. Turn the nut (f) while keeping it pressed to prevent the lever (d) from turning, and tighten it until there is (a) little resistance. Move the lever d of the front axle 2 to “OPEN” facing the notch (e). With the lever (d) caught in the notch (e), turn and tighten until there is a little resistance in the lever.
Determine the position in which the lever d is to be fastened, lower it in the direction in which the stamp “CLOSE” is visible, then fasten it.
Position the lever when it cannot touch obstacles while the bicycle is moving. If not, the lever could be unlocked unexpectedly, causing the front wheel to come off, resulting in an accident with severe injury or death.
Fasten the lever (d) at position where the tip does not touch other parts when the lever (d) is lowered.
Fasten the lever (d) facing backward from the direction of travel in such a way that it cannot easily touch obstacles that might be encountered while riding.
INSTALLING THE INCLUDED PARTS (CONT'D)
If the lever (d) of the front axle (2) is too hard and cannot be lowered, or if it is too loose and cannot be lowered for it to be locked, turn the lever (d) again to loosen or tighten it, adjusting so that it can be fastened securely.

3. Installing the handlebar
Install the handlebar (a) so that the knurled part (b) is at the center of the handlebar holder (c), then tighten the (4) handlebar holder (c) bolts (d) to the specified torque.
The handlebar (a) should not touch the frame when it is turned fully to the left or right.
Install the handlebar (a) so that the brake levers (e) are at a 45 degree angle to the handlebar, as shown in the illustration.
-Tighten bolts (d) evenly in stages, in the order shown in the illustration.
-Tighten in such a way that the gaps (f) above and below the handlebar holder (c) are equal.
- Adjusting the display unit position Adjust the display unit (a) position so that it is close to the brake lever (b), and tighten the bolt (c) to the specified torque.
Install the display unit (a) so that it is at a 30 degree angle as shown.

8. Routing the wires
Be sure to route the wires as shown in the illustration. If not, they could interfere with handlebar operation which could cause loss of control.
Confirm that hoses and wires are routed in order starting from front to back:
Front brake hose (1)
Rear brake hose (2)
Shift wire (3)
Headlight lead (4)
Display unit lead (5)
Fasten the front brake hose (1) and rear brake hose (2) to the wire clip (6) at the position shown. Fasten the rear brake hose (2) and shift wire (3) to the wire clip (7) at the position shown.
-The routing order of the rear brake hose (2) and shift wire (3) does not matter.
-The routing order of the headlight lead (4) and display unit lead (5) does not matter.
Fasten the headlight lead (4), and display unit lead (5) with the plastic locking tie (8), and then make sure that they are routed as shown.
Fasten the rear brake hose (2) and shift wire (3) with the plastic locking tie (9), and then make sure that they are routed as shown. Make sure that the front brake hose (1) is routed as shown.
INSTALLING THE INCLUDED PARTS (CONT'D)
Make sure that the rear brake hose (2), shift wire (3), and speed sensor lead (0) are routed as shown.
9. Tightening the seat pin
Insert the saddle and seat post (1), then tighten the bolt (a) to the specified torque.
| No. | Part names | Q'ty | Remarks |
|---|---|---|---|
| (1) | Saddle and seat post | 1 | A |
Insert the seat post far enough that the raise limit (b) is not visible. If installed at (a) position at which the raise limit (b) is visible, the seat post, clamp, or even frame may break, which could cause the rider to lose control and fall.
Always tighten fasteners to the correct torque. Bolts that are too tight can stretch and deform. Bolts that are too loose can move and fatigue. Either mistake can lead to a sudden failure of the bolt, causing the rider to lose control and Fall.
When lowering the saddle, do not insert the seat post all the way. Otherwise, the lower end of the seat post will contact the seat band, and as a result the seat post and seat band could be damaged. If the seat post is nevertheless inserted all the way, fasten the seat post after pulling it up slightly.

Install the rear reflector 1, band 2, screw 3, and nut 4 as shown, and then tighten them together to the specified torque. Secure them to the frame with the band 2.
| No. | Part names | Q'ty | Remarks |
|---|---|---|---|
| (1) | Rear reflector | 1 | B |
| (2) | Band | 1 | B |
| (3) | Screw | 1 | B |
| (4) | Nut | 1 | B |
