Weighing in at just 28 pounds, Carbo is the world’s lightest folding e-bike. It’s got a carbon fiber frame, an efficient Samsung battery integrated into the seatpost, a range of 40 miles in pedal-assist mode or 28 miles in full electric at speeds up to 20mph. It also unfolds to ride or folds back up in just 10 seconds. Easy peazy. A funded Indiegogo.
