Torker’s latest edition of their popular adult 3-wheeler is now available as an electric assisted model. The added power to your pedaling comes from a highly efficient battery-powered Protanium front hub. The Protanium hub is powered by a lightweight Lithium Ion battery attached under the rear basket. For charging, the battery easily slips in and out and plugs in to any outlet. Electrical assistance can be used for up to 25-40 miles (depending on rider weight and degree of terrain being ridden).
