“Can I squeeze a ride in?” “Do I have the legs to see where this side road goes?” “A ride would feel great, but do I have the energy?” Confluence Flat Bar CUES 11 answers these questions with an “Oh yeah.” Its MAHLE hub-drive system delivers 40Nm of electric assist to give you the extra push you need to ride more. Confluence’s geometry is designed specifically for the extra comfort and confidence you want for riding gravel e-bikes at higher average speeds on sketchy roads. The aluminum frame and carbon fork balance weight, comfort, and performance. Cargo and fender mounts let you configure your Confluence your way. The Shimano CUES 11-speed drivetrain tops it all off with smooth shifting and a massive gear range. Charge Your Adventure with Confluence Flat Bar CUES 11.


- 6061-T6 alloy frame
Confluence’s aluminum alloy tubing is developed specifically for the Confluence frame and is heat-treated to T6 alloy standards for extra strength and durability.

- Carbon fiber fork
The Confluence Carbon fork is lightweight, comfortable, cargo-ready, and gives you loads of tire clearance to play with.

- MAHLE X35+ Class 1 hub-drive system
This Class 1 rear hub-drive motor delivers electric assist up to 20mph/32kph. It’s one of the lightest ebike systems on the market, and its low-profile appearance means that Confluence looks like a regular gravel bike.

- 40Nm max torque
Up to 40Nm of assist that feels natural, not overwhelming. The MAHLE X35+ system offers three assist levels, and sensors detect when you’re pedaling to moderate the level of support generated at the hub.

- 250Wh internal battery
You can’t see it, but you’ll certainly feel it. MAHLE’s 250Wh battery is nestled inside Confluence’s downtube. This battery size hits the ideal combination of efficiency and weight for what we designed Confluence to do.

- Capable of up to 458Wh with MAHLE Range Extender battery? (sold separately)
Easily increase your range for bigger adventures with a Range Extender battery available from MAHLE.

- iWOC One compact remote top tube controller
Minimal and intuitive controller displays battery status and allows you to cycle through assist modes with one button.

- Connected if you want to be
The MAHLE system offers Ant+ connectivity for third-party devices and Bluetooth® for app integration. MAHLE’s MySmartBike app allows for customization, metrics, mapping, and more.

- Massive 700c x 50mm tire clearance
Confluence fits up to 700c x 50mm tires, so you can ride those lesser-traveled tracks. 700c x 42mm maximum tire clearance when equipped with fenders.

- On-bike cargo features
Attach front and rear racks to your Confluence for serious cargo capacity, or use the sleeker Three-Pack mounts for extra water bottles or our EXP Series Anything Cage HD to pack a cooking kit, extra layers, or whatever dream up.
