Introduction Thank you for choosing a Yamaha Power Assist Bicycle. NOTICE • This manual contains important safety, performance and service information. Read it before you take the first ride on your new bicycle, and keep it for reference. • Additional safety, performance and service information for specific components such as suspension or pedals on your bicycle, or for accessories such as helmets or lights that you purchase, may also be available.
General warning Like any sport, bicycling involves risk of injury and damage. By choosing to ride a bicycle, you assume the responsibility for that risk, so you need to know — and to practice — the rules of safe and responsible riding and of proper use and maintenance. Proper use and maintenance of your bicycle reduces risk of injury. This manual contains many “Warnings” and “Notices” concerning the consequences of failure to maintain or inspect your bicycle and of failure to follow safe cycling practices.

Safety information Do not press the pushig assist switch if the rear tire is off the ground. Otherwise, the tire will turn at high speed in the air and you could be injured. Do not use the wireless function with Bluetooth low energy technology in areas such as hospitals or medical institutions where use of electronic equipment or wireless equipment is prohibited. Otherwise, this could affect the medical equipment, etc. and cause an accident.

Adjusting the display angle Adjust the display angle by loosening the clamp bolt. The angle depends on each rider. After adjustment, tighten the clamp bolt. WARNING Clamp bolt Tighten the clamp bolt to 3.0–4.5 N·m (0.30–0.45 kgf·m, 2.2–3-3 lb·ft). During riding, vibration could cause the clamp bolt to come loose with the risk that the clamp may fall off. A loose display could distract the rider or interfere with control.
Displaying and switching the assist mode Assist mode lamp Assist mode indicator Assist mode Assist mode indicator Assist mode lamp EXPW Yellow HIGH Blue STD Blue ECO Green +ECO Green OFF Hide You can select the assist mode by using the assist mode switches (up & down). The selected assist mode is displayed by the assist mode indicator and assist mode lamp color.
Battery capacity indicator The battery capacity indicator displays an estimate of how much capacity is left in the battery. Battery capacity indicator Assist power meter The assist power meter displays an estimate of the assist power during riding. When the e-Bike Systems are not in operation, none of the segments of the assist power meter are displayed. When the e-Bike Systems are operating, as the assist power increases, the segments of the assist power meter are added one by one.
Odometer This displays the total distance (in miles or kilometers) ridden while the power was on. The odometer cannot be reset. Trip meter This displays the total riding distance (in miles or kilometers) since it was last reset. When you turn off the power, the data up to that point will remain in the display. For the procedure of resetting the trip meter to measure a new distance travelled, see “Stopwatch and settings”.
Cadence This displays your pedaling speed in revolutions per minute. The pedaling cadence display cannot be reset. TIP If you pedal in backward, “0” is displayed. Clock Displays the current time in 24 hour format. To adjust the time, see “Stopwatch and settings”. Backlight Each time the backlight switch is pressed, the backlight of the function display repeats on and off. Pushing assist When you are on or off the bicycle and start moving it, you can use pushing assist without pedaling the bicycle.
Stopwatch and settings The display enables the following. • STOPWATCH Stopwatch function • TIME ADJ (TIME ADJUST) Clock setting • DIST UNIT (DISTANCE UNIT) mile/km setting • DSPL ITEM (DISPLAY ITEM) Sets the items to be displayed in the function display during normal riding. Main riding display [ ] [S---] [S] [ ][ ] [S] [ ][ ] [S] [ ][ ][ ] [S] [ ][ ] [S] [ ][ ][ 1. Press the function select switch for 2 seconds or longer. 2.
STOPWATCH The stopwatch counts time in seconds up to a maximum of 9 hours 59 minutes 59 seconds. If this maximum is reached, it will automatically start over from 0 (zero) and continue counting. • TIME MEASUREMENT Use the function select switch to start and stop time measurement. Press the function select switch for 2 seconds or longer to “RESET” the measured time. • RESET When the function select switch is pressed, the measured time will be reset and the measuring display will be shown.
