Hard Enduro legend Graham Jarvis has officially unveiled his latest project – the JARV-E, a revolutionary electric hard-enduro motorcycle designed specifically for the demands of extreme off-road riding.

Developed alongside Austrian engineer David Freidinger, the JARV-E has been built from the ground up as a purpose-built electric machine for modern hard enduro and trial-enduro terrain. Unlike many electric off-road bikes which are adapted from other platforms, the JARV-E was designed specifically for technical climbs, rock gardens and balance-focused riding.

Jarvis himself played a major role in testing and development, shaping everything from the chassis geometry to the power delivery and regenerative braking settings to create a bike that delivers the precision and traction needed for extreme enduro competition.

Built for Hard Enduro

The JARV-E aims to combine the benefits of modern electric drivetrain technology with the handling characteristics required for technical off-road riding. Its design focuses heavily on low-speed control, instant torque and rider adjustability, all crucial elements in today’s hard enduro races.

The bike features a lightweight Chromoly race frame, a custom CNC-milled swingarm and high-performance suspension designed for extreme terrain. A traditional 21-inch front and 18-inch rear wheel setup ensures compatibility with standard hard-enduro tyres and setups.

One of the standout innovations is the quick-release battery system, allowing riders to swap batteries in around 20–30 seconds, making it possible to continue riding without long charging stops during trail rides or events.

Performance and Range

Despite weighing only around 95 kg, the JARV-E produces a maximum output of 50 kW (around 67 hp), giving it a power-to-weight ratio comparable to many traditional petrol-powered enduro bikes.

The bike is powered by a 5.6 kWh battery pack which can deliver different riding durations depending on the selected riding mode:

• Fast Race mode – around 1.5 to 2 hours of riding
• Mixed Enduro mode – approximately 3 to 4 hours
• Super Eco mode – up to 5 hours of riding time

Charging from empty to full takes around 1.5 hours with the 3.4 kW fast charger, while the quick-swap battery option provides an even faster solution for long rides.

Smart Technology and App Control

The JARV-E also integrates modern digital technology through a dedicated smartphone app that allows riders to monitor real-time data and adjust key parameters such as power delivery, regenerative braking and throttle response directly from their phone.

Pre-programmed riding modes developed with Graham Jarvis are included, allowing riders to quickly adapt the bike’s behaviour to different terrain conditions.

Limited Production Model

The launch version of the bike, known as the Graham Jarvis Signature RAW model, will be produced in a limited run of just 100 individually numbered units. Production is expected to begin in 2026, with pre-orders already open for European customers.

With its lightweight chassis, powerful electric drivetrain and purpose-built hard enduro geometry, the JARV-E could represent an important step forward for electric off-road motorcycles as the sport continues to explore new technology.
