Settings
P01: Backlight Brightness (1: darkest; 3: brightest)
P02: Mileage Unit (0: KM; 1: MILE)
P03: Voltage Class: 24V / 36V (default) / 48V
P04: Hibernation Time (0: never, other figures refer to the hibernation time) Unit: minute
PO5: PAS Level — 0/3 Gear Mode 1/5 Gear Mode
P06: Wheel Diameter Unit: inch Precision: 0.1
* To get an accurate speed display, this parameter should be correct.
P07: Magnet Steel Number for Speed Test Range: 1-100
* To get an accurate speed display, this parameter should be correct.
Gearless Motor: the value is the magnet steel number.
Geared Motor: the reduction-gear ratio is required. The value = magnet steel number*
reduction-gear ratio.
P08: Speed Limit
Range: 0-100km/h, parameter 100 indicates no speed limit.
This parameter limits the max. speed of the vehicle.
Deviation: t1km/h (applies to both PAS and throttle mode).
Note: The above-mentioned values are measured by metric units (kilometers). When
the measuring unit is switched to the imperial unit (mile), the speed value displayed on
the panel will be automatically switched to the corresponding imperial unit, however, the
speed limit value in the imperial unit interface won’t change accordingly.
IMPORTANT: P09-P15 only works under communications mode.
PO9: Zero / Non-zero Start Setting:
0: Zero Start1: Non-zero Start
P10: Drive Mode Setting
0: Power Drive — The specific gear of the assist drive decides the assist power value. In this status, the handlebar does not work.
1: Electric Drive — The vehicle is driven by the handlebar. In this status, the power gear does not work.
2: Power Drive + Electric Drive — Electric drive does not work in zero-start status.
P11: PAS Sensibility Range: 1-24
P12: Assist Power Intensity Range: 0-5
P13: Power Magnet Steel Number: 5 /8/ 12pcs
P14: Current Limit Value: 12A by default; Range: 1-20A
P15: Unspecified
P16: ODO Zero-Out: Long press the upper key for 5 seconds and ODO will zero out.
Motor Maintenance
- Please check the integrity of the motor blocking piece regularly.
- Please check the integrity of the cable before and after riding.

FAQ
- Is there a power usage or battery gauge on the bike?
Yes, there is a full-screen LCD display. There is also an additional LED battery gauge on the side of the battery pack. 2x the info! - Is there a switch to prevent accidental starting?
Yes, there is an on/off button on the battery pack. The brake levers also come standard with a safety power stop switch built in. - How do | lock it up and what can | do to help minimize the chance of it being stolen?
AOSTIRMOTOR Bike has some great anti-theft features, including a locking battery rack with keys to keep the bike safe, and a rear wheel that is bolted down to reduce the chances to be stolen.
Most standard U-locks and cable locks work fine on our AOSTIRMOTOR Ebike. - Does it work in the rain?
The components are all waterproof and work very well in wet conditions, But we do not suggest using our bike on a rainy day.
We suggest that you should keep your bike parked indoors and keep him in a dry situation.
