Bosch launched the primary drive unit for e-mountain bikes nearly ten years in the past – since then, the drive has undergone a number of phases of evolution. The German producer now introduced the most recent model. The Efficiency Line CX now boasts 600 watts of most energy, 85 Nm of torque and as much as 340 per cent assist. For power storage, Bosch has developed the PowerTube 800, which is customised for the brand new Efficiency Line CX. At round 205 Wh/kg, the battery has the best power density within the portfolio. Alternatively, the marginally smaller PowerTube 600 is accessible. The numbers within the product identify stand for the watt hours.
Bosch states that each batteries use battery cells with an optimised power density and a newly developed aluminium housing. “Due to their similar size, they are often simply eliminated and changed – if offered for by the eBike producer. They’re additionally DualBattery-capable and might be mixed,” the corporate says. Furthermore, “eMTB lovers, for instance, can use two PowerTube 800s to attain a complete capability of 1,600 Wh.”
The producer additionally guarantees extra exact fine-tuning. That’s made attainable by an improved interpretation of a number of high-performance sensors that exactly measure the pedal enter – greater than 1,000 occasions per second, based on Bosch. Particularly, the sensor know-how features a high-resolution cadence sensor, torque measurement know-how and inertial sensors (IMU) that measure acceleration and rotation charges in six dimensions and recognise incline and decline angles in addition to vibrations.
“Due to the sensors, the eMTB is aware of how steep the slope is and offers optimum assist,” Bosch explains. Bosch engineers have additionally lowered the noise and weight of the Drive Unit. As well as, the producer cites optimised braking efficiency (‘Bosch eBike ABS Professional’), a brand new hill begin assist and an improved pushing assist as additional options of the brand new drive era. The Efficiency Line CX can be flanked by varied using modes that may be chosen and customised through the app (‘eBike Circulation App’).
“The brand new Efficiency Line CX (BDU384Y) delivers the best stability of energy, dynamics, effectivity and vary,” mentioned Claus Fleischer, CEO of Bosch eBike Methods. “Whether or not for delicate begins on steep trails or highly effective, completely managed exits from bends: With its exact, delicate response behaviour, our new drive unit permits sporty eBikers to expertise distinctive using dynamics for the right eMTB expertise.”
