Why is there some noise when I brake?
Due to the new bike's disc brakes needing a break-in period, if the squeaking issue persists after some time, loosen the screws on both sides to ensure the brake pads and disc are perpendicular.
Can the handlebars of the A4 be adjusted for height?
Yes, the handlebars of both our A4 and A2 models can be adjusted for height.
What is the biggest feature of A4?
As the second-generation foldable model launched by Aipas, the A4 has substantially improved performance compared to the previous generation A2. It excels over the A2 in terms of speed (the motor has been upgraded from 750W to 1000W). Additionally, we have made adjustments to enhance comfort, lowering the frame of the vehicle to facilitate easy boarding.
Will there be safety risks with the battery on the outside of A4?
Our battery is UL certified, so there are no issues with everyday use. However, it's advisable to avoid placing it near sources of fire or other hazardous areas. Additionally, all our vehicle batteries and accessories are rated IPX6 for water resistance, meaning they can operate even in rainy weather. Nevertheless, for safety reasons, it's best not to use them in rainy conditions.
Why did I buy two e-bikes but only receive one tracking number or have them arrive at different times?
Since each e-bike is shipped separately, it’s possible that due to the shipping carrier, they may arrive at different times. Please don’t worry. If you have any questions, feel free to contact our customer service department for the latest updates.

The bike is a good ride. The seat is too small for my comfort but will get a bigger size seat.
Good Quality- was surprised at the power to climb steep hills near our north Ga. mountain home. Of course pedal- assist was useful for maintaining speed on some of the steeper hills.
