So looking at my first ebike, and after spending countless hours settled on a Mariner. Have tried multiple times to contact VoltBike with a simple capacity question, but have never received a response? This makes me nervous to commit purchasing from VoltBike, as one has to wonder if support is ever needed, will they be there? Any VoltBike owners recently contacted support, and received replies? I hate to start the search over, but may have to look at other manufacturers at this point?
