Do you have a question about the Bosch WHYTE E-Lyte 140 and is the answer not in the manual?

The Whyte E-Lyte is an Electrically Power Assisted Cycle (EPAC) designed as a full suspension e-mountain bike. It is available in 140mm and 150mm travel versions, with the E-Lyte 140 having a shock stroke of 47.5mm and the E-Lyte 150 having a shock stroke of 50.0mm. Both models feature a Bosch electric system, including a Bosch motor, battery, and display. The bike is designed for single-rider use and is not intended for multi-rider cycling equipment.

Function Description:

The E-Lyte provides electric assistance to pedaling, with the drive working only when the rider is pedaling. The drive automatically switches off at speeds over 25 km/h (15.5 mph) and becomes available again when the speed falls below this threshold. An exception is the walk assistance function, which allows the eBike to be pushed at low speed without pedaling. The eBike can also be used as a normal bicycle without assistance by switching off the eBike or setting the assistance level to OFF. The drive power depends on pedaling force and cadence, with higher force and cadence resulting in more support. The bike is equipped with hydraulic disc brakes, which offer powerful braking.
