A cargo bike is one of the best frame choices for an electric bike because of its capability to hold many pounds of battery. Not only that, but your imagination can run wild on everything else that they can carry. Owning a cargo electric bike can be like owning a truck…but be careful…pretty soon everyone will want a favor or a pick up. It’s like owning a truck. For an electric biker, the extra few pounds that a cargo bike frame weighs is of no serious significance or consequence , especially given the extra capacity for battery stowage.
