What everybody really needs to know is what battery voltage and Ampere hour of the battery and who the battery is made by. what is the hub wattage of the motor.... And most people can figure it out from there
You might be able to find a more powerful battery if you look around the internet. Either that or try and find if the battery has a speed governor and turn it off…might reduce the miles but you could get more power in return. Lmk if you find anything
There is always a couple of questions that remain on these reviews [from anyone not just jack] whats the durability how long do all the bits last how long is the battery good for?
I usually try to make update videos after a while using them. but this bike is pretty cheap so I don't expect it to last very long if it's abused at all. that said, it does have standard bike equipment that has been proven to last years with normal use.
