Bosch Performance Line CX

The 2017 Bosch Performance Line CX is a high-end electric power assist system. The CX is the top performer from Bosch's stable, able to produce as much as 75 Nm of torque, optionally equipped with a 500 watt hour battery, and effective at quite high rotational speeds. As always the motor is accompanied by a bar-mounted controller that also offers cycle-computer functionality and an optional eShift automatic shifting system, compatible with NuVinci, Shimano and SRAM systems. The versatile quick charger can charge from house current or lighter socket.
A very good electric-assist system.
