Comfort + customization 

Automatic shifting. Effortless riding.

Available on Charter+ 5S models, Bosch and Shimano Auto Shift technology automatically adjusts your gears based on terrain and speed, so you can focus on enjoying the ride — not when to shift.

A dialed fit, every ride

Charter+ fits the way you ride. Comfortable, balanced geometry and a fully adjustable stem lets you fine-tune your position and enjoy the same great fit every time you roll out. 

See how it works

Ride smooth. Ride confident. 

Front suspension, a suspension seatpost, and wide, fast-rolling tires soak up bumps and add stability, so you can ride comfortably and confidently on pavement, paths, and light gravel. 

Load up and roll out 

A 60 lb-rated MIK HD rear rack makes it easy to haul cargo or a child seat, while full fenders and a chainguard keep you (and your gear) clean and comfortable.

Power + range

Power that keeps life moving 

With up to 85Nm of torque, the Bosch Performance Line Sport Smart System gives you smooth, responsive assist for faster starts, easier climbs, and lighter-feeling rides — even when you’re loaded up. 

All the speed you need

Charter+ offers assisted speeds up to 28 mph, helping you ride farther, faster, and with confidence. 

Long-range freedom 

Charter+ features a high-capacity, removable Bosch battery — 540Wh or 800Wh — for up to 45 or 68 miles of reliable range.

A better battery experience

Charter+ features an easy-to-use, top-eject battery with a magnetic, color-matched cover and integrated strap for effortless charging, storage, and carrying.

Safety + security

See and be seen 

Integrated running lights powered by the main battery help you stay seen day or night. The stem-mounted front light turns with your steering, while a high beam brightens the road after dark.

Connected and in control 

The Bosch eBike Flow app connects seamlessly with Charter+, giving you digital locking, theft alerts, customizable ride modes, and navigation — all from your phone. 

Refined, inside and out

Seamlessly integrated components, clean cable routing, and an elevated chainstay come together for a refined look and premium ride experience.
