Rohloff E-14 DC/DC-CAN Converter

New standards for shifting eBikes - the Rohloff E-14

The Rohloff E-14 DC/DC-CAN converter serves as the central electronic link between the E-14 and the Bosch drive system. It is used for communication between the individual components. It also ensures the power supply. The converter is mounted in the seat tube. Among other things, the adjustment range of the seat tube must be taken into account.

The new electronic Rohloff E-14 offers a unique performance, shifts intelligently, lightning fast and comfortably like no other. Added to this is the legendary quality of Rohloff. Combined with the Bosch eShift function, an overall system has been developed that more than meets the demands of touring and city riders as well as extreme athletes. Thanks to the flawless shifting unit, every shift will run smoothly in the future!

One press of the button and the drive takes the load from the system and the Rohloff E-14 shifts. Hold the button down and the E-14 shifts all 14 gears in a quick sequence of 3 (Multi-Shift). And when the bike stops at traffic lights, it automatically shifts back to the starting gear (Auto-Downshift). The most efficient and durable gearstick for all eBikes with a mid-motor.

The E-14 is not afraid of torque

Of course, Rohloff takes as a basis its SPEEDHUB 500/14 rear hub, proven and reliable for 20 years, with its 14 gears and 526% efficiency - more is not possible with gear hubs. In eBike use, too, it turned out that this hub is the only durable option for mid-mounted motors, which makes it the ideal choice even for S-pedelecs with the most powerful motors.An electronic system, consisting of the shift unit on the handlebar and the shift control unit on the hub, takes over the shift control, coordinates the ideal time to change gear with the drive system and then engages the selected gear in an unbelievable 180 ms or 0.18 sec. The result: a velvety smooth gear change!

The E-14 system has a wireless connection so that updates and settings can be made in the future. The system can also be accessed via an app.

Bosch as the perfect partner

The Bosch displays Intuvia, Nyon and Kiox show the gear change or permanently the engaged gear, depending on the setting.

The Bosch eBike system synchronises with the Rohloff E-14. You can feel the impressive advantage of this with a light press on the shift button - the next gear is engaged as smooth as velvet. The secret behind it: The moment you trigger the gear change, the Bosch system takes load from the drivetrain for a tiny moment and in a rapid 180 ms the new gear is engaged by the E14. No other gearstick is currently faster.

The Rohloff E-14 achieves even more shifting comfort via Multi-Shift. This makes it possible to shift up and down 3 gears in one sequence. Finally, Auto-Downshift: When stopping at traffic lights, the Bosch eBike system communicates with the Rohloff E-14 and automatically downshifts to an individually selectable starting gear.

Another advantage of this combination of Rohloff E-14 and Bosch is the increased range and the resulting reduced number of charging cycles.

Attention!
Currently, the Rohloff E-14 cannot be retrofitted. Currently, the Rohloff E-14 electronic shift control is only available on new eBikes with Bosch drive systems. These include Active Line and Active Line Plus as well as Performance Line and Performance Line CX and Bosch Gen 4 in combination with the Intuvia, Nyon and Kiox displays. There is currently no compatibility with other eBike systems (e.g. Brose, Shimano STEPS, Yamaha, Panasonic, etc.).

The conversion of an eBike with Bosch system with mechanically shifted Speedhub or other shifting systems requires a reprogramming of the motor control, which is currently not possible.

Converting a bike without an e-drive is also currently not possible, as the E-14 power supply is provided via the eBike system.
