STOMP Haywire Bikes Are Coming Soon. [Select "Notify Me When Available" to be alerted.]
The STOMP Haywire fills a gap in the eMoto market that has existed for years.
Most electric dirt bikes fall into one of two categories: lightweight eMotos designed around smaller chassis platforms, or premium full-size bikes with premium price tags. The Haywire offers something different—a true full-size electric dirt bike with legitimate dirt bike ergonomics, strong performance, and a price point that puts it within reach of far more riders.
When our Haywire arrived at ECR, the first thing that surprised us was its size. We expected something closer to an Ultra Bee. What we found was a motorcycle that feels every bit like a full-size dirt bike. The rider triangle is spacious, the seat is comfortable, and the overall ergonomics work exceptionally well for adult riders.
Powered by a 21kW drivetrain and 74V 50Ah battery, the Haywire delivers smooth throttle response, strong low-end torque, and impressive trail performance. Whether you're exploring singletrack, riding backroads, or looking for a comfortable enduro-style eMoto, the Haywire checks a lot of boxes.

Who Is The Stomp Haywire For?
The Haywire is ideal for riders who want:
- A full-size electric dirt bike
- Comfortable ergonomics for adult riders
- Trail and enduro-focused performance
- A more affordable alternative to premium full-size eMotos
- Standard 21"/18" dirt bike wheel sizing
- A bike that feels closer to a traditional motorcycle than a lightweight eMoto
The Haywire feels most at home on trails, forest roads, dual-sport routes, and enduro terrain.
Rather than chasing motocross race-bike characteristics, STOMP focused on creating a motorcycle that is comfortable, capable, and confidence inspiring in real-world riding situations. The suspension delivers a plush ride, the chassis feels stable, and the power delivery makes technical terrain easy to manage while still providing plenty of acceleration when you want it.
For riders who have felt cramped on smaller eMotos, the Haywire's full-size dimensions are immediately noticeable.
