Hi all, I am new to this forum and new to e-bikes. Last week, there was a surprise auction for a new/used e-bike store that went bankrupt. I thought it would be a nice gift if I bought my son a bike. Unknowingly, I purchased this bike that has no battery or charger and also no manufacturer's name that I can find. If anyone can help, it would be immensely appreciated. Thank you. Ps.: I am not even sure if the motor is still good. Is there anyway I can test the motor before I buy a battery?
