What payment methods do you accept?

Can you still ride it as a normal push bike when the electric runs out?

Yes, when the battery runs out, most electric bikes can still be ridden like a normal bicycle by pedaling manually. However, the weight of the electric components, such as the motor and battery, may make it slightly heavier than a standard push bike. The ride might require more effort, but it's definitely possible to continue riding without power assistance.
