Confluence Flat Bar Altus opens up more ride opportunities with a MAHLE hub-drive electric assist good for 40Nm of torque.

The aluminum frame and carbon fork strike a balance of durability and performance you’ll appreciate, with frame and fork cargo mounts to keep you fueled on those longer rides, or to load up with bikepacking gear. Shimano’s Altus 1x9 drivetrain is a proven workhorse that will get you through any ride without a fuss. Charge Your Adventure with Confluence Flat Bar Altus.
FEATURES:
- 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 in-market, and its low-profile appearance mean 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 else you dream up.
