The ride, not just the specs
Charter is an electric bike for everyday riding. The motor flattens the hills and shortens the miles, so the bike becomes the easy choice.
It's ready for commuting, errands, and longer weekend rides.
What makes it special
The Bosch eBike Flow app gives you more control with digital locking, theft alerts, customizable ride modes, and navigation — all from your phone.
Charter+ comes with a high-capacity, top-eject Bosch battery for long rides and easy charging. The color-matched, lockable magnetic cover makes it secure, sleek, and simple to use.
