E-14 2.0 with the Bosch Smart System

The E-14 2.0 connects directly to the Bosch Smart System’s CAN bus and constantly monitors the motor’s assistance level, the crank position and how hard you pedal. When you press + or –, the system:

1. waits for the ideal crank position to shift,
2. reduces the motor’s assistance,
3. sends the shift command to the E-14 shift unit, which shifts to the gear you want,
4. restores the assistance.

The whole thing takes about 0.2 seconds. Power comes from the e-bike battery; no separate battery is needed.

What makes it good: load-free shifting, every gear at a standstill, Multishift, starting gear, automatic mode, setup with the E-14 2.0 app, no restrictions on S-Pedelecs — and since you are always in the right gear, range goes up and the drivetrain wears less. For operation, see Operating the E-14 2.0 with the Bosch Smart System.

The system’s parts

The parts and wiring in general: System overview. On the Bosch Smart System, the central element is the DC-CAN adapter; you shift with the Rohloff handlebar button or the Rohloff Trigger.

Fitting the DC-CAN adapter

The DC-CAN adapter links the drive system and the E-14: all parts get their power and talk to each other through it. It goes into the down tube or seat tube, which means removing the Bosch motor from the frame.

1. Before pushing the adapter into the frame, connect the purple 6-pin connecting cable — in the length that suits the frame — and plug the orange 4-pin Bosch plug into the Bosch High Power Port (HPP).
2. Pull the handlebar button’s blue 4-pin cable from below, through the Bosch mounting bracket, up inside the frame to the handlebar.
3. Push the adapter in from below through the bracket — padded with foam if needed, so it does not rattle.

Note

The first adapter (8802-04) always connects to the HPP. Its successor, the DC-CAN Adapter2 (8802-05), can connect to either the HPP or the BCC. When fitting it in the seat tube, mind the seatpost’s adjustment range.

The red tag

The red tag on the adapter’s orange plug warns: Do NOT connect HPP located at Bosch BCC — E-14 can be damaged. In other words, do not plug the old adapter (8802-04) into the port on the Bosch BCC, or the E-14 can be damaged — its place is the motor’s High Power Port.

Fitting the handlebar button or Trigger

For fitting the Rohloff handlebar button, see Installation on Bosch BES2 and Panasonic FIT1 — it works the same way.

The Rohloff Trigger shifts with two levers and fits only 22.2 mm handlebars, on the right, between grip and brake lever — not on the left.

1. Undo the clamp’s two screws (TX10) and take the clamp off.
2. Place the Trigger between grip and brake lever with its cable pointing towards the middle of the bar, so you reach both levers comfortably with thumb and index finger.
3. Refit the clamp — wide side forward, lined up with the Trigger’s guide — and gently screw in the front screw until no gap remains. Tighten it to 0.8 Nm, then the rear one to 0.8 Nm.

Caution

Use only an exactly fitting TX10 Torx bit — similar bits with a different profile damage the screw head. The clamp must go onto the bar without force. Check the brake lever touches nothing when pulled.

Finally, connect the Trigger’s blue 4-pin plug to the DC-CAN adapter’s blue 4-pin socket.

Route and fix the cable on bar and frame so it cannot kink, twist or get trapped when steering or braking, and cannot chafe at cable ports. Do not clean the Trigger with a pressure washer; use a soft cloth lightly dampened with water, without cleaners, oils or silicone spray.
