This guide explains how to assemble the AUTOMATiQ hub interface on a wheel with a 148mm modular axle hub, and then how to assemble the rear wheel onto the bike frame.
Backward compatibility
This guide is compatible with legacy enviolo and NuVinci 148mm modular axle hubs.
Spline nut options
There are different Automatic hub interfaces (AHI) depending on the number of teeth on the spline (A). You can find the identification of the AUTOMATiQ hub interface variant at the bottom of the hub interface on the serial # sticker.
Their compatibility with enviolo CVPs - hubs and gearbox - depends on the release date of the CVP. See the overview below:
MY2025
-
40T
- All hubs and gearbox - from 2025, all CVPs are commonized with 40T.
-
44T
- Not applicable - from 2025, no CVP will be produced with 44T.
MY2024 and earlier
-
40T
- Specific 135mm solid axle CVPs - Heavy Duty, Extreme, Extreme Gearbox, CA.
- All 148mm modular axle CVPs.
-
44T
- Specific 135mm solid axle CVP hubs - Urban, City, Trekking, CO, SP, CA.

Step-by-step instructions
1 - Assemble the AUTOMATiQ hub interface
Before you start
Ensure you have the correct AUTOMATiQ hub Interface for your internal gear hub. There are 2 variants for the AUTOMATiQ - 40T and 44T. Make sure you have the right one for your hub, otherwise forcing entry might damage the spline nut.
Tools
- 17mm flat wrench
- Torque wrench with 17mm socket
- 5mm hex wrench
- 3mm hex wrench
Assembly instructions
-
Use the uninstalled hub interface to determine the desired orientation.
-
Orientation should be forward, parallel to the chainstay with the AUTOMATiQ main connector facing forward (A).

Orientation should be forward, parallel to the chainstay with the AUTOMATiQ main connector facing forward (A).
-
Move the AUTOMATiQ hub interface along the dropout to ensure clearance at different axle positions (B).
- Remove the anti-shift retainer if one is installed on the hub.
- The anti-shift retainer comes typically installed on new hubs.
- The anti-shift retainer comes typically installed on new hubs.
-
Match the position of the AHI 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.
- Fix the torque arm with 3mm hex wrench
- When the assembly angle is aligned, seat the AUTOMATiQ hub interface fully onto the axle.
-
Thread the right-hand nut, serrations facing outward, onto the axle.
- Tighten it to 8-10 Nm.
2 - Assemble the rear wheel
Exercise caution when assembling
Improper installation may result in damage to the dropout and the hub. Over-tightening may damage parts. Under-tightening can result in the axle sliding in the dropouts.

Tools
- 15mm wrench
- Torque wrench
- 15mm long socket
- 17mm long socket (only for Extreme hub)
- Allen key 5mm
Assembly instructions
- Place the disc brake rotor on the hub.
- 148mm variants require an extra adapter to be placed under the rotor and need to be tightened with the longer bolts supplied with the kit.
- Tighten the rotor bolts as specified by the brake rotor manufacturer.
- For rim and roller brake applications, connect the rear brake according to the manufacturer's instructions.
- 148mm variants require an extra adapter to be placed under the rotor and need to be tightened with the longer bolts supplied with the kit.
- 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.
- The cable housing should be able to enter the hub interface in a straight line.
- Place the rear wheel in the frame with the torque adapter sliding into the slot in the dropout or disc adapter.
- Install the left and right side adapters securing the axle with the M6 bolts to 10-15Nm.
- On the right side, ensure the spring washer is positioned between the hub interface and the adapter.
- Finally, assemble the power cable carefully by inserting it into the AUTOMATiQ hub interface (C).
Proceed to the next guide
If you successfully followed the steps above, then the wheel is on the bicycle with an AUTOMATiQ hub interface.
For the next step, if you installed a new AUTOMATiQ, then first you will need to upload a configuration. If so, proceed to this guide:
If you just reinstalled the same AUTOMATiQ on the same bicycle, then chances are it already has a configuration. In that case, proceed directly to calibrating:
