Niner Bikes e9 Series, Powered by Bosch

Our new e9 series of ebikes is powered exclusively by Bosch, a global leader in ebike technology. Even with an expanding range of available drive systems, the choice to partner with Bosch was easy for Niner.

Bosch has been building ebike motors for over a decade. Bosch’s original pedal-assist motor is based on a Mercedes power steering unit developed by Bosch but was too expensive for the auto industry. The motor has evolved since then and in 2019, they released the Performance Line.

The Bosch Performance Line CX

Bosch’s Performance Line CX motor is 40% smaller and reduced in weight by 700 grams (26%) while increasing efficiency (more range for the same battery) and keeping the torque performance, compared to the prior version.

  • Bosch has the most responsive (fastest processing speed) torque sensor on the market. It’s 20x faster than the nearest competitor. This means the system adds assistance faster and also shuts off faster when the rider stops pedaling.
  • Bosch’s battery is the only UL listed battery and charger on the market for safety. Niner is utilizing Bosch’s new PowerTube battery with 625 Wh sizes integrated into the frame to optimize low center of gravity.
  • Bosch’s battery offers the most energy density on the market today, translating to the most range per kilogram of battery, making bikes lighter.
  • Bosch has the largest service network and their automotive-grade diagnostics system makes it easy for technicians to monitor Bosch drive systems.

Bosch offers a 2-year warranty on their systems and is conservative in their estimate of system life. Testers have run motors for over 5 years and 30,000 miles.

Bosch Performance Line CX Motor

Bosch’s motor is the most efficient on the market today with the flattest torque curve. This means that at a cadence of 30-110 rpm the torque is even and available to the rider. The torque sensor is 20x faster than any other on the market, thanks to a faster processor, resulting in zero-lag power delivery.

  • 85Nm max torque returns a sporty ride feel.
  • 340% maximum power assist.
  • Class-leading torque management for smooth, predictable power delivery.
  • Efficient motor makes full use of available energy.
  • No drag and no overheating.
  • Noise optimized gearbox is quiet and discreet.
