WELCOME TO SRAM EAGLE POWERTRAIN

Eagle Powertrain is holistically engineered to eliminate distractions and amplify your fun. Made to prove that easy is right. Through a series of videos and articles, we’ll cover the basics of your Eagle Powertrain bike, from trail-ready tech tips, to harnessing the potential of infinite personalization. Read on to get the most from your new bike in 10 easy steps.

RIDE ESSENTIALS

Let’s meet the system. Auto Shift senses and translates rider input to deliver an incredibly intuitive experience, while Coast Shift allows the chainring to move freely from the cranks, letting you shift while coasting. Eagle Powertrain features radical simplicity thanks to only two ride modes, unmatched integration with Eagle Transmission, clean and simple rider control, and AXS enabled personalization. Go for the better ride. 

STEP 1: TURN IT ON

Located on your top tube is the Eagle Powertrain AXS Bridge Display. This sophisticated nerve center provides everything you need to know in a full color, waterproof module. Conveniently, it is also where you turn on your system. Press and hold the Power button to power on your bike.

STEP 2: LEARN YOUR CONTROLS

Your versatile two-button AXS Pod Controllers contain four primary rider commands and three secondary rider commands without the need to clutter the handlebar with additional remotes or bar-mounted displays.

To differentiate between primary and secondary commands there are two ways to press your Pod buttons: a press-and-release Short Press, and a press-and-hold Long Press. We’ll get into how to use these commands shortly, but first let’s get to know your controls.

Short Press Controls

Long Press Controls

STEP 3: AXS BRIDGE DISPLAY FUNCTIONS

Your Eagle Powertrain AXS Bridge Display features two buttons with both short and long press controls for four commands. You can turn the system on/off, open component pairing, toggle Range and Rally Ride Modes, and place it in Service Mode.

STEP 4: POWERTRAIN SYSTEM BATTERY

Your Eagle Powertrain bike contains a primary system battery that powers the motor, the AXS Bridge Display, as well as your Eagle Transmission derailleur. You should expect to charge this battery before your first ride, and again after every ride, to ensure you’re always ready to go.

Check Your Battery Status 

Real time battery status can be found on the main screen of the AXS Bridge Display when riding or during charging. It can also be located within the SRAM AXS App.  

Battery Range 

Battery range is controlled by a number of factors: how you ride, the terrain you choose, total rider and gear weight, as well as which ride mode and level of assistance you utilize. Eagle Powertrain batteries offer enough capacity for most E-MTB rides, but it might take a couple rides to fully understand how long you can ride with how you choose to ride. 

For those unique instances when you do need more, we offer a 250Wh Range Extender that offers up to 40% more capacity. 

Charge your Battery 

To charge your bike, first plug your battery charger into a wall outlet. Next, remove the Charge Port cover on your bike and insert the plug end of the battery charger into the charge port. Your AXS Bridge Display will indicate charging and will display current charge progress. 

When charging from 0 to 100% with the Eagle Powertrain Charger you can expect the following charge times: 

  • 720Wh Battery = ~5 hours 
  • 630Wh Battery = ~4.5 hours 
  • 250Wh Range Extender Battery = ~2 hours 

TECH TIP: Your Eagle Powertrain battery will automatically enter a sleep mode when it reaches 100% during a charging cycle. To wake the battery, unplug the bike and turn the system on.

STEP 5: AXS COMPONENT BATTERIES

Your AXS Pod Controllers are powered by common CR2032 batteries, and if equipped, your Reverb AXS dropper post is powered by a SRAM AXS battery.

Check Your Battery Status

Press the AXS button on each component to check the status. An LED will flash on your Pod Controller or dropper post indicating the battery status of each component. 

  • GREEN = More than 25% of battery charge remaining 
  • RED = Between 10% and 25% of battery charge remaining 
  • FLASHING RED = Less than 10% of battery charge remaining  

Charge Your Battery

AXS batteries take an hour to charge and last for approximately 60 hours of riding time. The CR2032 batteries last up to two years. To preserve battery life, AXS components go to sleep when the bike is stationary. Shake it to wake it.  

TECH TIP: Your Eagle Transmission derailleur is powered by your Eagle Powertrain system battery. If you ever drain your system battery, enough power is reserved for yourderailleur so you can continue shifting.

STEP 6: KNOW YOUR MODES

Where others give you unnecessary power modes and confusing names, your Eagle Powertrain uses just two.

Range Mode: With a short press of the top button on your left Pod controller, toggle to Range Mode for longer routes, easier terrain or when conserving power is a good move.

Rally Mode: Toggle to Rally Mode for shorter rides or whenever you want access to the full capabilities of full power.

TECH TIP: Enter Service Mode by short pressing the On/Off Button on the Bridge Display. Service Mode turns the motor support off while keeping the system on. This is essential for pedaling and shifting while in a bike stand, or for riding without motor support.  

STEP 7: AUTO SHIFT & PEDAL SPEED ADJUST 

What could feel more natural than not having to think about shifting while you ride? Long press the top button on your right Pod controller to toggle Auto Shift on/off. Auto Shift senses and translates rider input and speed to deliver an incredibly intuitive shifting experience.

Auto Shift allows you to set your desired Pedal Speed when Auto Shift is On. The MID Setting is the recommended starting point to learn the system. If you prefer to pedal with a higher cadence, adjust the value higher (+1, +2, +3). For lower cadence, adjust down (-1, -2, -3). The system will then know how fast or slow you prefer to pedal and shift accordingly.

TECH TIP: Do you need to temporarily take control? Override Auto Shift by simply initiating a shift on your AXS Pod Controller. Auto Shift will remain on, and will take regain control shortly.

STEP 8: PUSH MODE

When you need to hike up to ride down, you may need an extra push. Long Press the top button on your left Pod controller to initiate Eagle Powertrain’s Push Mode. Once the Bridge Display confirms the mode selection, you will need to roll the bike forward or backward to initiate motor support.

STEP 9: BETTER BRAKING

The brake bed-in procedure will get your bike ready for the demands of mountain biking, ensuring the lowest brake noise and consistent performance. Bed-in is the process of controlled slowing to gradually heat the braking surface while evenly embedding brake pad material into the disc rotor.
