Standard items

Interface & magnet rings

In any retrofit, you will always need to have these 3 Enviolo parts:

Automatic hub interface	Hub magnet ring	Sprocket magnet ring

Wire harness

You will also need one of these Enviolo wire harnesses:

BOSCH BES1 and BES2 (in addition to a Bosch Y-shape cable)	Harmony retrofit cable (in addition to a Y-shaped cable from an old Harmony setup)	BOSCH BES3 HPP compatible	Open-ended cable for custom solutions

Optional items

Additionally, you may want to include an optional CliQ Pro controller, which you can fit and pair later on in the retrofit. Depending on your case, you may need a compatible Y-shaped cable to connect the Automatic hub interface harness to the drive system.

Step-by-step instructions

1 - Make sure you have the right cable harness

We offer 3 cable variants:

• J6 - Open-ended cable for custom solutions
  • WIRE-AT3-DS1K-OE (1000 mm)
• J6 - J15 BOSCH BES2 (Gen2, Gen3, and Gen4)
  • WIRE-AT3-400-OE (400 mm)
  • WIRE-AT3-600-OE (600 mm)
• J6 - J10 BOSCH BES3
  • WIRE-AT-600-OE-12V (600 mm)
  • WIRE-AT-800-OE-12V (800 mm)

Remember that other partners (e.g. Serial 1, FIT, Specialized) offer their own wire harness solutions.

Open-ended cable for custom solutions

When working on custom solutions, please take the following into account:

• Input power for the latest Enviolo AutomatiQ (OE-1) must be between 9.5 - 55V. For older Enviolo AutomatiQ (OE) versions, the power input must be between 18 - 55V.
• Use the WIRE-AT3-DS-OE open-end wire to connect to your drive system.
• See this guide for more information on open-ended Enviolo Automatic cables.

Warranty when using custom open-ended cables

Always consult local (country, state) warranty regulations first before using customized solutions.

You may need approval from the engine manufacturer to avoid losing the engine’s warranty if you connect the Enviolo Automatic to the engine using a custom open-ended cable.

2 - Disassemble the old magnet rings

The previous magnet rings (see example below), will no longer measure correctly with the new Enviolo Automatic (e.g. calibration will no longer work).

Make sure to use the current model rings. Current magnet rings have yellow stickers on the inside (see below).

Legacy magnet rings

These were the previous hub magnet rings:

• A - Automatic, Automatic+ (these have a white sticker inside).
• B - Harmony, Harmony H|sync (these look like part of the hub shell).

Tools

• 2,5mm Allen key
• Flat screwdriver (optional)

Disassembly instructions

Disassemble the legacy sprocket magnet ring

• Remove the old sprocket magnet.
  • The previous sprocket magnet ring is just clipped in and can be easily removed without a tool.

Disassemble the legacy hub magnet ring

For the Automatic, or Automatic+ ring:

• Remove the old magnet ring using a 2,5mm Allen key.

For the Harmony, or Harmony H|sync ring:

• Remove the old magnet disk.
  • Use the help of a flat screwdriver to lift the disk
  • Note that this magnet disc can be confused as being part of the hub shell.

3 - Assemble the new magnet rings

New magnet rings

Sprocket ring

The Enviolo Automatic (AutomatiQ) system comes with a sprocket magnet ring (A) that must be secured onto the assembled sprocket snap ring on the hub. The twelve magnets on the sprocket magnet ring provide a pedal cadence to the Enviolo Automatic system.

Hub ring

Additionally, the Enviolo Automatic system also requires a hub magnet ring (B) that must be secured over the internal gear hub, and flush with the internal gear hub cover. Six magnets in the hub magnet ring provide the eBike speed for the Enviolo Automatic system.

You’ll need to assemble both for the system to work.

Use the right version of the magnet rings

Current magnet rings have yellow stickers on the inside (see the example above).

Pre-2024 freewheels – snapring freewheel)

Post-2024 freewheels – threaded freewheel

Tools

• 2,5mm Allen key
• Sprocket magnet ring
• Hub magnet ring (for the Urban hub this is a smaller version) 

Assembly instructions

Assemble the sprocket magnet ring

1. Place the sprocket on the hub.
2. Place the sprocket spacer (skip if you have a Gates sprocket).
3. Place the snap ring.
4. Install the sprocket magnet ring over the assembled sprocket snap ring (A).
   • Make sure the magnets are facing the sprocket.
   • Make sure the “tooth” on the sprocket magnet ring aligns with the opening of the sprocket snap ring.

Assemble the hub magnet ring

1. Install the hub magnet ring over the right-hand side of the hub.
2. Secure the magnet ring with the included fastener (D).
   • The fastener may need to be unthreaded to allow initial fitment.
   • The magnet ring should face the larger diameter flange outboard and the fastener inboard.
   • The magnet ring should not stick out too much, and it should be aligned with the flat surface of the hub (as shown below).
3. Torque the fastener to 1.0 Nm (9 in-lbs).
   • Make sure the fixation point is not on one of the outside spokes.

4 - Assemble the Enviolo Automatic interface

You can assemble the AUTOMATiQ on two different axle types:

• 135mm solid axle wheel
• 148mm modular axle wheel

Follow the correct instructions below for your bike.

4.A - On a 135mm solid axle wheel

Video

Tools

• Scratch pen or marker
• Torque wrench with 17mm socket

Assembly instructions

1. Before installation, use the interface to determine the orientation on the frame.
   • Orientation should be forward, parallel to the chainstay with the connector facing forward (A).
2. Move the interface along the dropout to ensure clearance at different axle positions (B).
3. Use a scratch pen or marker to mark the hub interface in the middle of the dropout.
4. Remove the anti-shift retainer if one is installed on the hub.
   • The anti-shift retainer comes typically installed on new hubs.
     
5. Suspend the Enviolo Automatic interface over the right-hand axle, and align the axle flats with the marked position.
   • A no-turn washer can be installed over the Enviolo Automatic interface to align the assembly angle.
6. When the assembly angle is aligned, seat the Enviolo Automatic interface fully onto the axle.
7. Thread the right-hand nut, serrations facing outward, onto the axle.
   • Tighten it to 8-10 Nm.

4.B - On a 148mm modular axle wheel

Video

Tools

• 17mm flat wrench
• Torque wrench with 17mm socket
• 5mm hex wrench
• 3mm hex wrench

Assembly instructions

1. Use the uninstalled hub interface to determine the desired orientation.
   • Orientation should be forward, parallel to the chainstay with the Enviolo Automatic (AutomatiQ) main connector facing forward (A).
     
2. Move the Enviolo Automatic (AutomatiQ) interface along the dropout to ensure clearance at different axle positions (B).
   
3. Remove the anti-shift retainer if one is installed on the hub.
   • The anti-shift retainer comes typically installed on new hubs.
     
4. Match the position of the interface with the position of torque arm on the other (left) side of hub.
   • Place the torque arm onto the axle and orientate it in an angle that it slides into the boss on the brake adapter or dropout.
   • Note: The torque arm can only be mount in three positions.
5. Fix the torque arm with 3mm hex wrench
6. When the assembly angle is aligned, seat the Enviolo Automatic interface fully onto the axle.
7. Thread the right-hand nut, serrations facing outward, onto the axle.
   • Tighten it to 8-10 Nm.
