Put the Outer Cover onto the Motor Drive Unit, and se-

cure it with included self taping screws.

Use the shortest screw for the position under the RS-

232C connector, and use the middle ones for the lower

stairs of the Outer Cover. The other longer screws are

used for the top of the cover.

Install the Head Controller onto your handlebar.

If it will not lock down securely, insert something like

handlebar tape, electrical tape, etc. between the handle-

bar and the bracket so the unit is securely attached to

your handlebar.

Connect the Head Controller to the Motor Drive Unit

with the included RS-232C serial cable (male-to-male

connector in white). Wire should be routed along the

left side of the bicycle frame and AWAY from the crank

arms.
