I cannot install the AROFLY sensor on the tire valve.
Confirm the type of cycle tire valve. The AROFLY sensor can only be used on the rear tire valve, with a Schrader or Presta valve. For the Schrader valve, the AROFLY sensor can be installed directly, and for the Presta valve, please use the adapter included. Ensure that the pin on the Presta valve is open all the way up, then screw on the Presta valve adapter. Ensure you can see or touch the pin on the Presta valve adapter. Then only, screw the AROFLY Sensor on the adapter. You will hear an air sound indicating that the AROFLY sensor pin and the Presta valve pin, have made contact. Continue to screw down quickly and tighten.

Will air escape after installing the AROFLY sensor ?
Tightly twist the AROFLY sensor on the tire valve. This will act like a normal tire valve cap. If the
X-ELITE GPS Bike Computer shows, low tire pressure because the tire was not inflated for a long
time, it is normal to see “low tire pressure”. The tire should be inflated to the correct tire
The riding data is abnormal
1. Please do not use the AROFLY sensor on tires containing a sealant.
2. Low tire pressure: The tire pressure is not at optimal level as per the tire manufacturer’s
suggested range. Please inflate your tire to the optimal tire pressure.
3. The BIKE TYPE and Wheel size is not set correctly in the X-ELITE GPS Bike Computer.
4. The cyclist’s BODY WEIGHT is not set correctly in the X-ELITE GPS Bike Computer.
5. AROFLY sensor, MUST be installed ONLY on the REAR tire. Ensure it is installed correctly.
6. When training indoors, please ensure to use the correct Indoor training equipment. The
AROFLY system requires the bike’s rear tire to be on the rollers.
Please use the complete roller type, which is, (one roller in front and two rollers at the back)
or the rear roller type, which is, (a tripod in the front and a roller behind). It performs better
on rollers without the resistance attached.
Rear roller type
7. Please confirm whether the INDOOR/OUTDOOR mode is selected correctly.
Why is it always showing low pressure?
When the tire pressure is at the optimal, but, there is always a warning of ” low tire pressure”.
Please check and be sure of the correct bike type and wheel size selection.
Can the CADENCE sensor only be attached on the left crank?
Yes, please attach the CADENCE sensor only on the left crank to avoid sticking with the
chainring. Besides, we also provide the L/R Pedal Ratio, attaching on the left crank can provide
more accurate data.

Please turn off the Indoor Mode by going to the SET MODE on the X-ELITE GPS Bike
Computer. (Please refer to the quick start guide, how to use “SET MODE”)
2. Reminder Message: LOW TIRE PRESSURE
If this message shows on the X-ELITE GPS Bike Computer, please check the following:
(1) Check whether the tire pressure is at optimal level as the tire manufacturer’s
suggested range. (Such as Road Bike 90~120 psi ; Mountain Bike 35~65psi)
(2) Ensure that the AROFLY sensor has been twisted tight, to avoid air leakage
(3) If the tire is punctured to cause air leakage?
* For Road bikes, if the tire pressure is lower than 80psi, will see the “ Low Tire Pressure”
* For Mountain bikes, if tire pressure is lower than 35psi, will see the “Low Tire Pressure”
3. Reminder Message: CHECK VALVE
The tire air did not go in the AROFLY sensor for the detection.
Please re-install the sensor and twist it tightly. Check for cross thread when twisting the
AROFLY sensor on the tire valve.

For your own safety, in heavy rain conditions it is not recommend to engage in outdoor cycling
Are products with Anti-theft device?
All AROFLY products are quick and simple to Install and uninstall. If your bike needs to be
parked outside, it is strongly recommended to uninstall before leaving the bike outside.
Is it required to install the CADENCE sensor if the users only request the data of Power?
The package of the AROFLY X-ELITE, includes AROFLY power meter sensor, CADENCE senor, and
the X-ELITE GPS bike computer. This package is a complete system to provide overall riding
data to the users. By patented algorithm and sensor fusion via powerful MCU computing and
filtering, it generates the useful and reliable Power output for users.
It offers speed, cadence, altitude sensors as sensor fusion to assist computing and filtering out
different road conditions and riding status.
What is L/R PEDAL RATIO? How does it measure?
AROFLY system measures the Dual-Sided PEDAL RATIO.
It measures your Left and Right pedaling velocity from the upper dead point to bottom dead
point and through our algorithm to calculate the L/R pedal ratio. When your pedaling force is
more, the pedaling velocity is higher. The opposite is true, when pedaling force is less, the
pedaling velocity is lower. In regular and normal pedaling, the L/R pedal ratio is positive
correlated to power ratio.
Why the data will be delayed for around 2-4 seconds when pedaling?
Breaking the traditional mechanics of power meters, AROFLY simultaneously senses tire
pressure variations and analyzes the data by patented algorithms. The system does
“AVERAGING” for smooth data output. Therefore, it will take about 4 seconds to analyze when
riding indoor and 2 seconds when riding outdoor.
How does it measure Power?
AROFLY Power Meter sensor inbuilt high sensitivity Pressure Sensor can measure the tiny, tire
pressure variations. When pedaling, the pedaling force is through the bike transmission system
and eventually to the tire, which makes contact with the ground and causes the tire
This tire deformation varies the tire pressure. AROFLY sensor measures this tire pressure
variation and computes via our patent algorithms to get Power Output. The package of AROFLY
X-ELITE, includes AROFLY power meter sensor, CADENCE senor, and X-ELITE GPS bike computer.
It offers accelerator, cadence, altitude sensors as sensor fusion to assist computing and filtering
different road circumstances and riding status. This package can be regarded as a system to
provide overall riding data to users.
By patented algorithm and sensor fusion via powerful MCU computing and filtering, it
generates the useful and reliable Power output to users.
Can the X-ELITE GPS Bike Computer paired with other CADENCE sensors?
The package of AROFLY X-ELITE is a complete system, we customize the CADENCE sensor with a
software for this system only. Hence it is not workable with OTHER CADENCE sensors.
Why does it take so long to upload the files to the ACLOUD via the AROFLY 2 APP ?
