Universal Bike Controller

The Universal Bike Controller is an open-source project aimed at providing a drop-in replacement for the factory console on NordicTrack® S-series exercise bikes (s10i, s15i, s22i, and s27i). This project allows you to upgrade and customize your bike's control system with new features and improvements.

Explanation

The factory consoles on NordicTrack® S-series bikes may lack certain features or customization options that users desire. The Universal Bike Controller project addresses these limitations by providing an open-source solution that simplifies the hardware on the bike while unlocking connectivity to other third-party apps (Zwift®, Rouvy®, Peloton®) and smart devices.

(Tablet not included)

Features

• Drop-in replacement controller for the iFit console (cannot be used together with OEM console)
• Full incline and resistance control via OEM handlebar pushbuttons
• Wireless connectivity to a variety of third-party applications (RPM, Watts, and auto-incline adjustment)
• 3.5" TFT touchscreen for resetting elapsed time
• USB Type A fast charger port for charging
• Over-the-air support for future software upgrades

Installation

The replacement uBike console mounts in the current location of the weight tray and plugs into the same two cables as the factory console. Installation is as simple as follows:

1. Turn off the bike
2. Remove the 4 screws from the underside of the weight tray (save them) and remove the weight tray
3. Place the uBike controller in its place, with the connectors facing away from the rider
4. Use the same 4 screws removed from the weight tray to secure the uBike controller
5. Unplug the 2 cables from the factory console and plug them into the new uBike controller (Please see note below on compatability if you do not have a red and yellow connector)

Compatibility

The Universal Bike Controller is designed to be compatible with the following NordicTrack® S-series exercise bikes:

• s10i
• s15i
• s22i
• s27i

All of these versions have been tested and are working. Additionally, since 2021 bikes have stopped shipping with the yellow and red mini-DIN connectors to the console, instead they have cables coming directly out of the console. If your bike does not have the red and yellow connectors you will need to buy the cables below:

• Yellow mini-DIN-6 Connector - PN 411540 (eBay/HydraFitness)
• Red mini-DIN-8 Connector - PN 411536 (eBay/HydraFitness)
