Everyone’s raving about electric dirt bikes that few people can actually ride. So we built one you can: the 2026 Stomp Haywire — engineered to be ridden, not just talked about.
While others chase headlines and horsepower, and influencers drag race Lamborghinis, we’ve been focused on what really matters: tight trails, technical climbs, street sessions and wheelies. The result is a bike built to deliver where it counts.
A serious electric dirt bike for real riding — from enduro trails to urban streets.
