Key Features
On-Bike Storage
Carry more on your bike and less on your body. Our frames and forks feature mounts for extra bottles, camping gear, and ride accessories.
Electric Assist
Salsa ebikes use battery-powered electric assist to help riders ride more in less time or venture onto routes they wouldn’t otherwise.
6061-T6 Aluminum 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 Fibre 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.
Range
Ebike range depends on many factors, including rider and equipment weight, weather conditions, route choice, assist level and more. The MAHLE X35+ system paired with a 250Wh battery is designed to offer a range of up to 45 miles (72 kilometers) per charge under ideal conditions. MAHLE range-extender batteries (sold separately) greatly increase the ground you can cover with assist.
