The New Rohloff E-14: Synchronized Motor and Transmission

Rohloff AG (Germany) – "The new electronic Rohloff E-14 shifting system raises the bar for shifting E-bikes transmissions. Never before has shifting been so easy, intelligent and comfortable. All this combined with legendary Rohloff quality", stated the company about the new E-14 shifting system.

"The new E-14 from Rohloff synchronizes perfectly with the mid-motor, Bosch eBike system to operate the now legendary Rohloff Speedhub 500/14. Urban, leisure, touring and mountain-bikers alike can reap the benefit of the unique, fast and failure-free shifter system", they added.

One push of a button is all it takes to automatically reduce motor derived force upon the transmission and shift the SPEEDHUB. If the button is kept held, then the E-14 shifting system will shift 3-gears at a time in sequence, through all 14 gears if so desired. In addition, once the sensors note the cyclist has become stationary, the E-14 system will automatically shift to a pre-programmed gear to start off again. According to Rohloff, "the E-14 is the most efficient and durable shifting system available for mid-motor E-bikes".

Legendary Basis:

The E-14 is designed to complement the SPEEDHUB 500/14. This partnership ensures the durability of an E-14 shifting system.

With 14 real gears, a total overall gear range of 526% and the highest efficiency of any bicycle hub gear, the Rohloff SPEEDHUB 500/14 forms the durable basis of every premium, high powered E-Bike. Now, thanks E-14. the ability has arrived to shift this legendary transmission electronically.

The E-14 shifting system comprises of 2 main components: - the handlebar mounted electronic switch unit and the SPEEEDHUB mounted shifter unit. To ensure these components are relevant and compatible with future developments, we have made the E-14 shifting system Bluetooth LE compatible to accept software updates, custom features and app connectivity.

Effective with Bosch:

Both Intuvia and Nyon Bosch displays will integrate the gear indicator for E-14 equipped SPEEDHUBs. They will also show a lot more...

The Bosch eBike-System synchronizes itself automatically with the Rohloff E-14. The benefits of this become immediately apparent once you set off. A light press of a button will reduce motor torque to permit a silky-smooth shift between gears. The secret is an ultra-fast, 180ms shift speed combined with an instantaneous drop in output torque of the Bosch motor No other electronic bicycle shifting system available to date, can compete with this speed.

Further shifting comfort is achieved thanks to an integrated multi-shift and auto-downshift functions. Press and hold a shift button to shift sequentially in 3-gear steps – regardless of direction, right through the 14-speed range. And when you come to a halt, the E-14 shifting system will automatically return the SPEEDHUB to a pre-programmed gear number, ready to set off again.

Gear Indicator:
Integrated into Bosch cockpit display (Intuvia / Nyon). Gear number indicated either permanently or briefly depending upon cockpit version.

Single / Multi Shift:
Shift gears singularly or push and hold button to shift 3 gears simultaneously, following the initial single gear shift.

High Performance:
Also compatible with high torque / peak performance mid-motor units (Bosch Performance Line CX) –suitable for S-Pedelec use.

Fastest electronic shift available to date at 180 ms. Reduced force, synchronized shift process via CANBus connectivity.

Auto Downshift:
Automatically return to pre-programmed start gear once stationary.

Bluetooth LE:
For future pairing with a Rohloff App for set-up, updates and software extension installation via Bluetooth.
