This guide explains how to assemble the AUTOMATiQ hub interface on a wheel with a 135mm solid 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 135mm solid 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 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
- Scratch pen or marker
- Torque wrench with 17mm socket
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).
- Use a scratch pen or marker to mark the hub interface in the middle of the dropout.
- 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.
- Suspend the AUTOMATiQ hub interface over the right-hand axle, and align the axle flats with the marked position.
- A no-turn washer can be installed over the AUTOMATiQ hub interface to align the assembly angle.
- 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 the no-turn washers
Improper installation of the no-turn washers 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)
Assembly instructions
- Place the rear wheel into the frame.
- Make sure not to obstruct or pinch the wire harness and main connector.
- Orient the chain around the AUTOMATiQ hub interface and onto the sprocket.
- In some cases, it is easiest to remove the chain from the front chainring to ease rear wheel assembly.
- Locate the rear wheel speed sensor boss on the AUTOMATiQ Hub Interface.
- The chain should not catch on this sensor when fitting the wheel.
- Slide one non-turn washer (A) each onto each axle end.
- The serrations of the non-turn washer must bear against the dropout of the frame.
- The rectangular boss must engage in the dropout of the frame.
- Mount the axle nuts (B) and tighten to 30-40Nm.
- 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:
