The recommended bike size based on rider height is as follows. We also suggest visiting an Amflow authorized store for an in-person fitting to determine the best size for you:

Height 162-178cm: Size M
Height 170-185cm: Size L
Height 175-191cm: Size XL
Height 185-201cm: Size XXL

The following weights were measured on bikes in factory configuration, with the front and rear mudguards, lights, pedals, and frame protection film removed. The wheels were set up tubeless (inner tubes removed, tyre sealant added).
1. Amflow PX Carbon Pro (700Wh)
Size M: 20.6kg, size L: 20.8kg, size XL: 20.9kg, size XXL: 21.1kg

2. Amflow PX Carbon (700Wh)
Size M: 21.0kg, size L: 21.2kg, size XL: 21.3kg, size XXL: 21.5kg

* Weights may vary. Please refer to the actual product.

To connect the new Wireless Controllers, press and hold both buttons at the same time until the indicator light flashes green, then complete the connection in the Control Display.
If the indicator light flashes red, the battery is low and should be replaced.s.

Yes. For third-party bike computers, users need to purchase the required mounting adapter separately.
In addition, the Avinox Control Display and the Avinox Ride app already include comprehensive ride data, navigation, and other built-in features. We recommend trying the native system first. If you need additional functionality or have suggestions, we’d be happy to hear your feedback.

The following models have been tested and confirmed to be compatible:
DJI Osmo Action 5 Pro
DJI Osmo Action 6
DJI Osmo 360

It depends on the account you sign in with:
1. Signing in with the same account: Yes. Ride data is stored in the cloud and tied to your account, so you can still view your ride history in the app after pairing again.

2. Signing in with a different account: No. To protect user privacy, local data is cleared when the bike is unpaired, and a new account cannot access the previous account’s ride data.

Location accuracy is usually affected by satellite acquisition and environmental obstructions.
1. Inaccurate location when powering on
During a GNSS cold start, initial satellite acquisition can take longer, typically 3-5 minutes. When powering on the bike, move it to an open area to help the system acquire satellites more quickly.

2. Inaccurate location while riding
Buildings, metal structures, and other obstructions may weaken the signal, causing temporary delays or missed location updates. Once you return to an open area, the signal will recover and the location will update automatically.

Amflow PX automatically adjusts its maximum speed to comply with the regulations of the country/region you are in. Speed limits for major countries/regions are as follows:
European Union: 25km/h
United Kingdom: 25km/h
United States: 20mph
China: 25km/h
Australia: 25km/h

1. Assistance:
Adjusting the level of assistance involves modifying the assistance ratio of the drive unit. Increasing the assistance amplifies the assistance ratio, lessening the rider's pedal effort and making the ride easier. Conversely, reducing the assistance decreases the assistance ratio, increasing the rider's pedal effort and enhancing the rider's sense of participation in the ride.

2. Assistance Range:
The assistance range refers to the range of the assistance ratio of the drive unit. The minimum value of the assistance range represents the assistance ratio for riding on flat surfaces, while the maximum value represents the assistance ratio for riding on steep slopes. Within the rider's set assistance range, the assistance ratio dynamically adjusts based on the road gradient and resistance. If the rider sets the minimum and maximum values to the same number, the output of the assistance becomes independent of the road gradient and resistance, and the assistance will always be maintained at the set value by the rider.

3. Max. Torque in Auto and Trail modes:
The maximum torque represents the upper limit of the acceleration torque and also determines the upper limit of the bike's acceleration. Lowering the maximum torque slows down the bike's acceleration, while increasing it speeds up the acceleration. In this scenario, if one aims to achieve the same level of acceleration as with higher torque, additional effort from the rider is necessary.

4. Max. Torque in Eco and Turbo modes:
The maximum torque represents the maximum assistance value of the drive unit. Increasing the maximum torque can lead to faster acceleration under similar road conditions and easier uphill riding. However, on surfaces with low traction, such as icy roads, the rear wheel is more prone to slipping. Conversely, reducing acceleration and uphill riding becomes more strenuous, but the bike is less prone to slipping on such surfaces.

5. Assisted Start:
The Assisted Start determines the rate at which assistance increases from a pedal stop to pedal resumption. Boosting the Assisted Start facilitates easier incline starts and pedaling resumption after a stop on inclines. However, excessive Assisted Start can lead to instances of slipping and wheel lift during incline starts. Riders should prudently adjust this setting based on their abilities and road conditions. Reducing the Assisted Start diminishes acceleration during starts on flat ground.

6. Continued Assist:
The Continued Assist determines the sensitivity of the assist response to the rider's pedaling force. Increasing the Continued Assist enhances the responsiveness of the assist, leading to a quicker increase when the rider applies more force and a faster decrease when less force is applied. Conversely, decreasing the Continued Assist reduces the sensitivity of the assist, resulting in a slower increase when more pedal force is applied and a slower decrease when less force is applied.

7. Motor Overrun
Motor Overrun indicates the ongoing assistance provided for a duration after pedaling has ceased, gradually diminishing based on the assistance level at the point of stopping. Increasing the Motor Overrun prolongs this continued assistance. Motor Overrun is not continuously active. By assessing the bike's speed at the moment of pedal stopping, if significant acceleration is detected after ceasing pedaling, the overrun assistance will be proactively disengaged to ensure safety. When riders need to navigate significant obstacles such as tree roots, we recommend initially applying a strong pedal stroke before stopping to enhance the intensity of the overrun assistance, thereby aiding the rider in overcoming the obstacle more effectively.

Yes. If the Drive Unit is off or the battery has run out, you can ride it like a non-electrical bicycle by pedaling.

To ensure battery safety, it is recommended to use the original charger. If the charger is lost, please contact a dealer for assistance.

Battery installation/replacement requires removing the Drive Unit. It is recommended to visit the nearest Amflow authorized store for assistance, or if there is no store nearby, please contact online customer service for support.

144km.

* The 144km range was measured on a flat paved road with an 80kg rider on Amflow PX Carbon Pro (700Wh). Testing was conducted in the Eco assistance mode at a cadence of 65rpm and a speed of 21kph, with default assist settings. Actual range depends on factors like temperature and wind speed. Results may vary.

Using the Avinox 508W Charger
0–80%: 1h 16min
0–100%: 1h 46min

Using the Avinox 168W Charger
0–80%: 3h 54min
0–100%: 4h 52min

It is recommended to store the bike indoors and maintain a certain level of charge in the lithium battery to prevent irreversible damage to the Drive System from extreme weather and temperatures.s.

The battery is equipped with a battery health management system, which ensures battery health even when not fully charged.

Yes, you can download the Avinox Ride app and pair it with your bike. When a new version is available, the app will send an update prompt. Simply follow the instructions to update.
