What is the recommend age and height for the Stomp Haywire?

This bike is best suited for Adults / experienced riders and the recommended rider height is between Seat height 920 mm.

Who is the Stomp Haywire really for?

The Haywire is aimed at riders who already know they want a high-output electric dirt bike. It is not an entry-level machine and makes most sense for experienced, confident off-road riders.

How fast and how far can the Haywire go?

Current official figures put the Haywire at up to 65mph with a quoted 80km range, which is about 50 miles in ideal conditions.

What makes the Haywire more serious than the SFR models?

It gets a larger 74V 50Ah battery, more peak power, a 19/18 wheel setup, more suspension travel and a more substantial overall chassis, so it feels like a much bigger step toward motocross spec.

Is the Haywire still realistic to charge and manage at home?

For the performance level, yes. Official figures put charge time at around 3 hours, although it is still a large, powerful bike at roughly 89kg dry weight and should be treated accordingly.

Is the Stomp Haywire water resistant?

The Stomp Haywire is water-resistant and suitable for riding in very light rain. It is not fully waterproof and should not be submerged. Short term, your product can get a little wet and be in the rain, but any long-term exposure can cause serious problems.

Description

74V 50Ah battery
Up to 65mph top speed
19/18 wheel setup
200mm front suspension with 4-piston brakes

The Stomp Haywire Electric Dirt Bike is built for riders who want high-end electric off-road performance without compromise. This is a serious machine aimed at enduro and harder off-road use, with the kind of power, torque and chassis intent that places it firmly at the sharp end of the category. Everything about it is designed to feel bigger, stronger and more capable than an entry-level electric dirt bike.

The Haywire is not just about raw output though. What makes it so impressive is the complete package: quick-change battery convenience, full-size wheel setup, fully adjustable suspension and a proper performance-bike feel from the moment you look at it. It is the sort of bike that suits riders who want to push harder, ride longer and step into something that feels genuinely premium.

Why the Haywire stands out

Serious high-performance electric dirt bike for demanding riders
Built for harder enduro and off-road use, not just light play riding
Premium chassis and suspension setup to match the power on offer
Quick-change battery design adds real-world practicality

If you are looking for an electric dirt bike with genuine presence and top-tier intent, the Stomp Haywire is one of the standout options. It is fast, focused and unapologetically performance led.

The flagship high-power Stomp electric dirt bike

The Haywire sits at the top of this group, pairing huge peak output with a bigger chassis, longer travel and a spec sheet that is aimed squarely at serious off-road riders.

Power backed by proper componentry

With 200mm air-sprung forks, a DNM rear shock and 4-piston brakes, the Haywire has the hardware to support the kind of speed its 21kW peak output can generate.

Closer to a full motocross-style experience

A 19/18 wheel setup, 65mph headline speed and 74V 50Ah battery move the Haywire beyond compact pit-bike territory and much closer to a real electric motocross machine.
