Forbidden Dreadnought E 2026 - Tier 3 800w - Avinox M2 in Back

Season:MY27

Brand:Forbidden

Code:MY27-DreadE-T3-800

Introducing Dreadnought E. An e-MTB built from the ground up with a singular purpose – to charge through the most chaotic, rowdy lines you can find, and whisk you back to the top, asking for more. Big travel. Full power. Zero hesitation.

Featuring 170mm of rear travel paired with a 180mm fork, combined with a rearward, yet reserved axle path, Dreadnought E has the ability to plow when you drop your heels, but still offer pop and support when it’s needed to get off the ground or pump to generate that addictive speed.

Dreadnought E is spec’d with the all-new Avinox M2 and M2S drive systems. Tier 1 and Tier 2 run the Avinox M2S, a 2.6 kg unit delivering 130 Nm of torque (150 Nm Boost) and 1300 watts. Tier 3 and Tier 4 run the Avinox M2, weighing 2.65 kg, delivering 110 Nm of torque (125 Nm Boost) and 1100 watts. Both options can be paired with 600 Wh or 800 Wh batteries, so you can choose a lighter setup or maximum range depending on how deep the mission goes.

Dreadnought E isn’t here to play nice, it’s here to go further, hit harder, and redefine what a full-power, big-travel e-MTB is supposed to feel like.

Trifecta V3 Platform

The latest iteration of our Trifecta platform elevates the spellbinding ride characteristics you expect from a Forbidden to a new level. We’ve fine-tuned the rearward axle path, idler position, and kinematics (the holy trinity of ride characteristics) to deliver the best e-MTB we’ve ever ridden. The new platform also gives us more seat post insertion and allows us to neatly package the motor and battery.

Avinox Drive System

Dreadnought E is powered by the Avinox drive system in two trims depending on build kit. T1 and T2 get the M2S motor, delivering 130 Nm of torque (150 Nm Boost) and 1300 watts, in a 2.6 kg package. T3 and T4 run the M2 motor, delivering 110 Nm of torque (125 Nm Boost) and 1100 watts, with a motor weight of 2.65 kg. Both builds can be paired with 600 Wh or 800 Wh battery options, letting you choose between a lighter setup or maximum range.

Touch Screen and Controls

Dreadnought E features a 2-inch OLED full-colour Control Display as the interactive hub, enabling connectivity between the Avinox Drive Unit and your mobile device via the Avinox app. Tuneable assist modes, wireless handlebar controls, and an intuitive app set the Avinox system apart from the rest.

AXS Extension Cord Compatible

Dreadnought E builds that are specced with AXS transmission come equipped with SRAM’s AXS Extension Cord. The SRAM AXS Extension Cord connects the AXS transmission to the bike’s battery, allowing you to power the drivetrain directly without the use of an AXS battery.

Carbon Rocker Link

The Trifecta V3 platform features a carbon rocker link. The carbon rocker link is light, stiff, reduces unsprung mass, isolates the shock from lateral forces, and gives the bike the right amount of progressivity. 8 x 30 mm bearing hardware, top and bottom, comes as standard on all shocks.

Idler Pulley

Dreadnought E sports our e-bike-specific 18-tooth steel idler equipped with two Enduro solid lube bearings. These changes, along with a refined tooth profile, increase the idler’s longevity while ensuring compatibility with the latest drivetrains.

Custom Frame Protection

We developed a full complement of custom frame protection for Dreadnought E. Chainstay, seatstay, downtube, and motor cover protection have all been developed and designed in-house specifically for this bike.

Waterbottle Fitment

Even our smallest Dreadnought E frame size can fit a full-size 26oz water bottle, regardless of your rear shock reservoir. Remember, hydration is your friend, but sweaty backs most definitely are not.
