The Epure FACTOR-e is here

It all started in ELECTRIC MOTION’s R&D department.

After 15 years of exquisite experience in electric propulsion in the off-road sector and more specifically in trials, our ambition was to offer ‘THE’ trial bike of the market.

The origins of this powertrain date back to 2021. Since then, our engineering teams and Marc COLOMER in particular, have been working hard designing, testing, improving, optimizing and enhancing the reliability of this brand-new powertrain.

Marc COLOMER, former Trials World Champion, is in charge of bike development working closely with EM's expert design engineers.

3 years of research, data analysis, laboratory tests, trials on different tracks, tested by riders of all levels right up to the very highest... everything has been done to design the best trial powertrain unit ever made.

For EM, this propulsion had to be the most efficient at the highest level but also the most accessible, and only electric power can achieve this.

New engine by EM

The Epure FACTOR-e is equipped with a new powertrain designed 100% by EM. Innovative, it combines two technologies:

The advantage of an electric motor with instant low-end torque.

A power profile similar to a fuel bike, combining performance and driving pleasure.

This engine has an unmatched power-to-weight ratio (3.3kW/kg), an engine speed capable of reaching 14000rpm, power of up to 18kW, torque of 1400Nm in first gear, all in a specially designed oil pan to integrate this motor.

The high-performance rotor is surrounded by a carbon sleeve to hold the magnets in at extreme rotation speeds.

The air-cooling system has been designed to provide homogeneous and controlled heat dissipation.

Engine noise has been optimized to provide a very quiet and pleasant transmission, thanks to reduced friction.

Last but not least, the engine’s 40% extra inertia gain strongly enhances the roundness and power of the engine.

New gearbox

The 4-speed gearbox is an essential asset - not only for performance, but also for control and precision.

This innovative gearbox allows the rider to adapt to the bike’s behavior depending on the type of track, offering a versatile use:

1st (Trial):

Trials sections with clear steps and obstacles, precision is essential and the bike becomes dynamic and reactive.

2nd (Natural Trial):

The bike is more progressive, with more control and more grip in the obstacles, especially in the preparation before and after obstacles. Traction is accentuated, with a speed more suited to natural obstacles and/or long climbs.

3rd (Mixed):

This gear has been designed for mixed use – for both trial and excursion. (We get the same behavior as our Epure Race model).

This gear is also ideal for beginners, who can get their marks without using the gearbox.

4th (Excursion):

Ideal speed for riding between long lap trial sections and excursions thanks to its top speed and driving pleasure, allowing the rider to cruise at a comfortable speed on a trickle of throttle with appreciable mid to high rpm power whilst reducing power consumption.

New transmission

The huge acceleration capacity combined with the gearbox, offers infinite possibilities!

The Epure FACTOR-e is equipped with a new secondary transmission with 520 chain and a reinforced swing arm to subsist with the 1400Nm of torque.

Finally, the use of this gearbox also means lower energy consumption in fast use, efficiency being one of the priorities of this new propulsion unit.

The engine alone weights 5kg.

The propulsion unit, inertia, clutch, gearbox, sensors, oil pans, is 3kg lighter than our former propulsion unit.

New clutch

A new engine, gearbox, but also a new clutch.

Equipped with a triple-disc hydraulic diaphragm system, this new clutch gains in precision and responsiveness, and can handle the power and torque of the brand new engine.

New battery

Our previous-generation battery offered one of the best weight-to-range ratios. But at EM, we’re determined to maintain our technological lead with this new battery, developed in France at our factory.

The latest Li-Ion technology has been integrated by our R&D teams, along with a new PCB + Bus-bar connection system.

All the software has been improved for more safety, longevity and performance.

New casing, new side protection, new charging socket, new waterproof quick connectors, new "battery swap" system... everything has been redesigned and revised and revised to ensure the best performance, final touches and durability.

2 versions: Epure FACTOR-e 1.8 / Epure FACTOR-e 2.5

Are you an excursion enthusiast? There's now a long-range version in 2500Wh... all in the same battery case!

This new battery offers a 35% increase in autonomy over the standard while retaining the same power!

Epure FACTOR-e 1.8:

- Adapted to the practice of trial thanks to a 2kg weight saving on the front end.

- Delivered power is the same as the 2.5kWh battery.

Epure FACTOR-e 2.5:

- Designed for trial and excursion, this version offers over 35% more range.

The Epure FACTOR-e 2.5 is 3kg lighter than our Epure Race model.

Suspensions

The new TECH shock used by the best riders in the world, developed by Marc COLOMER and approved by Gael CHATAGNO is installed on the Epure FACTOR-e.

This shock provides optimized traction and precise rear-end feeling.

It comes with two settings, one for rebound adjustment (24 clicks), and one for spring preload (from 1mm to 10mm max).

The whole suspension system has been redesigned in line with the new weight and weight distribution.

Frame

Our specialist team also worked on the frame for the new Epure FACTOR-e. The steering-column assembly has been redesigned and stiffened to further enhance steering precision and the triple clamps have new offsets for a more dynamic front end.
