I bought an electrical bike. Delivery took almost two months. The bike came with two problems: (i) electrical discharges are occurring next to the rear wheel brake area and causing electrical shocks (ii) the rear tire valve is defective and is allowing all air to escape. Banggood after-sales is inexistent. I filled a form inside the order area, no answer. After that, I sent an email, also no answer. One month has passed since I received the defective bike. Be aware, you will have no warranty and no after-sale support when buying in banggood. Terrible service.
