Harmoniously balanced or assertively powerful? Natural is what's important. The Bosch riding sensation creates a unique eBike experience. Three sensors measure pedaling power, cadence, and speed more than 1000 times per second. This enables the rider and the eBike to interact with each other organically.
Bosch make several drive units:
The Performance Line CX is the one favoured by Trek for it's off road bikes,as it offers a 'very sporty' performance on Alpine terrain. Its 250w motor produces an impressive 75Nm of continuous torque. It delivers up to a 300% assist even at high cadence (120rpm max) enabling you to breeze up those climbs.
The low slung motor assists the bikes handling and the strong batteries provide assistance for up to 88km of riding. I've done several 4 hour, 30 mile very hilly off road rides around Kinder on the shops Powerfly and had 2 bars left on the battery (5 bars is fully charged).
Changing the level of assistance is easier than changing gears, thanks to the well place thumb controller.. The display unit provides basic ride information along with battery and power level information.
The Active Line motor is new for 2018 and suits city / leisure bikes best. It is lighter, only 2.9kg and delivers a more harmonious start up, while providing assistance upto a cadence of 100rpm. (more than enough for leisure riding)
