    When I have the problem, the bike brakes but when I release the brakes it goes back on its own. On the other hand, I've never had any problem deactivating the cruising mode by re-accelerating. I was not using the application the last time this happened. I'd rather say it was a firmware problem. However, I will try to re-install the application soon to see.

    Ebikes price and quality vary much even though they look the same on apperance,for example, lithium battery price is much higher and quality is much better than ebikes with lead acid battery, even though they both use lithium battery of both lead acid battery, its brand also makes price differ much, such as LG battery price is much higher than normal brand battery,of course it's quality also better. then it's about the material of ebikes, aluminum alloy material better and higher than metal material.
