Whether you opt for the exercise of pedaling yourself or being leisurely propelled at speeds up to 17mph without breaking a sweat, these electric bikes (think quiet mopeds) make beach cruising, exploring seaside ports or running errands a lot more fun. The high efficiency motor is powered by a lithium iron phosphate battery that offers a cruising range of 25-35 miles and then recharges in four hours. Marine-friendly features include an anodized and sandblasted 6061 aircraft-grade aluminum frame, Promax disc brakes and aluminum alloy wheels with heavy-duty, 12 gauge stainless steel spokes. Choose the Mariner with an oversized plush seat for comfort or the Mariner Sport with a gel pad in the seat for extended performance. Height-adjustable handlebars and suspension seatpost allow them to fit most riders, yet fold compactly for easy storage. Weighs 46lb. with rack. Ships fully assembled.
