We designed the Confluence Apex 1 to be the best gravel ebike for squeezing more adventure into each day. With a lightweight MAHLE hub-drive system putting out 40Nm of torque, it’s just the boost you need to head out for that lunch ride you deserve or that extra spin when your legs are feeling weary. Confluence’s aluminum frame and carbon fork are designed around geometry that puts you in a comfortable and stable position — especially important for putting in more miles at higher average speeds. Our on-bike cargo features let you bring all you need for those extra miles, and the e-assist lets you overpack without worrying about the weight penalty. Rounding it all out is SRAM’s Apex 1 drivetrain, delivering plenty of reliable gear range for wherever you point it. Charge Your Adventure with Confluence Apex 1.
