Unlike electric cars, e-bikes do not require special charging stations for battery-charging. In fact, most e-bike batteries can be charged by plugging it into the usual wall socket. Some e-bike batteries can also be easily removed for easier charging process. Usually, charging takes around 3 to 5 hours if you want it fully-charged.
On the other hand, replacing the e-bike battery can be quite expensive. However, the good news is that most e-bike batteries have warranty. Also, make sure to store your battery in a dry storage area to prevent any damages. However, if it is really time to replace your battery, expect to shell out up to $1,000 for a new one.
