ADDITIONAL FEATURES:

High-modulus carbon fiber frame

A carbon fiber frame keeps weight to a minimum and provides a custom-tuned blend of stiffness and compliance where it matters.

Class 5™ VRS

Our Class 5 VRS™ (vibration reduction system) design has specially shaped seatstays with a tall, thin, vertically oriented profile that promotes vertical compliance by allowing the seatstays to "flex" outwards on impacts. The horizontally oriented chainstays work to resist torque and maintain a laterally stiff rear end. The seatstays and chainstays lack bridges, furthering the full length of the stays to contribute to flexibility. And a rear thru-axle delivers precise tracking while allowing the seatstays to provide that incredible compliance.

Suspension fork

A 120mm suspension fork smooths out even the rowdiest forest roads.

Bosch Performance Line Speed mid-drive system

Bosch's Performance Line Speed with smart system is a Class 3* motor that delivers electric assist up to 28mph/45kph**. The mid-drive system delivers loads of torque and range, and keeps the motor's weight low and centered on the bike for neutral handling.

85Nm max torque

The Bosch Performance Line Speed system delivers up to 85Nm of assist, with four customizable assist levels and an integrated speed sensor to control torque output.

625Wh internal battery

The Bosch PowerTube 625 battery offers enough range to get lost on your favorite forest roads. It's also fully encased in the downtube for added stiffness and a nice, clean look.

Capable of up to 875Wh with range extender battery (sold separately)

The Bosch PowerMore 250 range extender battery bolts to your bottle-cage mounts for an extra 250Wh of assist. More range = more adventure.

Bosch smart system

The Bosch smart system integrates the drive unit, battery, display and control unit. Pair it with Bosch's Ebike Flow app to customize riding assist modes, enable navigation, and automatically download software updates. Fully connected, fully in control.

Bosch BRC3100 system controller

This minimalist top-tube controller displays assist mode and battery charge level, and lets you choose your assist mode - all without cluttering your cockpit.

29 x 2.6" tire clearance

The Tributary frame fits up to a 29 x 2.6" tire (29 x 2.4" with fenders). You'll love the traction and compliance of larger tires on rugged roads at the higher speeds ebikes allow.

Built for cargo

Tributary fits two bottles inside the frame on all sizes and features plenty of space for a frame bag. For heavier touring loads, outfit Tributary with a rear rack.

Internal Dropper Post Routing

Tributary welcomes 30.9mm dropper posts and keeps it tidy with internal cable routing. When the going gets technical, get low.

SRAM UDH Compatible

This derailleur hanger design allows for SRAM Full Mount derailleurs, optimizes shifting performance, and makes it much easier to replace a bent or broken hanger.
