Charter+ 4S Lowstep is a fast, luxury city e-bike built for comfort, ease, and style. The lowstep frame makes it easy to hop on and off, while front suspension and an adjustable stem keep your ride smooth and comfortable. A 28mph top speed and up to 45-mile range make quick work of commutes, and the top-eject battery makes charging simple. With bright lights, a high beam, and Bosch eBike Flow app security, every ride feels first class.
