Unlike bulky electric bikes that can weigh as much as 85 lbs., this is the world’s lightest model at a mere 26 lbs. Its A-shaped frame is made from aircraft-grade aluminum and easily condenses to a compact 8" W x 16 1/2" L x 27 1/4" H for storage in a closet, car trunk, or under a desk. Its 138-watt brushless motor assists a rider up hills or powers across broad flats for smooth cruising on 8" tires up to 12 1/2 mph. When in pedal-assist mode, the bike detects how fast you are pedaling, which prompts the motor to engage; can also be pedaled without powered assistance. With front and back band brakes, adjustable seat, and LED battery power display. Supports up to 220 lbs. Removable 24-volt rechargeable battery provides a 15-mile range on a full AC charge. Black. Deployed 37" L x 36" W x 18" D.
