Built-to-Survive Electric Dirt Bike for Young Riders
The MotoTec Demon 36v 790w Electric Dirt Bike delivers real trail performance for riders 13 and up. With a 36V 8Ah Li-Ion battery, you get up to 14 miles per charge — no gas, no noise, no fumes. The steel frame, front and rear disc brakes, and dual-shock suspension make this a built-to-survive machine that handles dirt trails and backyard terrain. Three parent-selectable speeds (5, 10, 21 MPH via key lock) keep things controlled while the variable twist-grip throttle teaches real throttle discipline. A field-tested setup for introducing the next generation to grid-independent riding.

No Gas, No Fumes, No Dependence
Gas-powered dirt bikes chain you to fuel runs, oil changes, and noise complaints from neighbors. The MotoTec Demon cuts that tether completely. Its 36V 8Ah Li-Ion battery charges at home — no gas can, no pull start, no two-stroke smoke. At Off Grid Vault, we only carry products we would trust for our own families, and this bike earns that standard. The 790-watt rare earth neodymium motor delivers real trail power through a chain drive, while the steel frame and full suspension handle real terrain. Parent-selectable speed locks at 5, 10, or 21 MPH mean you control the throttle until your rider is ready for full power. Field-tested on dirt trails and backyard tracks alike.
Real Suspension for Real Terrain
The Demon is not a toy with stiff forks pretending to be a dirt bike. Two front shocks and one rear shock absorb bumps, ruts, and trail irregularities that would buck a rider off a lesser frame. The steel frame provides the rigidity needed for aggressive off-road riding while the 2.5x10 knobby pneumatic tires grip loose dirt and gravel. Aluminum rims keep rotating weight down, so the 790-watt motor puts more energy into forward motion. Front and rear disc brakes deliver consistent stopping power in wet or dry conditions — not the marginal braking you get from cable-actuated calipers. This is a built-to-survive setup designed for kids who actually ride trails, not driveways.
Parent Control Without Compromise
Three selectable speeds — 5, 10, and 21 MPH — lock via key, so you decide when your rider is ready for more power. That is not a restriction; it is a progression system. Start at walking speed while they learn throttle control and braking on the variable twist-grip. Move to 10 MPH when their reflexes sharpen. Unlock the full 21 MPH when the trail demands it. The onboard battery meter keeps you informed of charge level so you are never stranded mid-ride. A padded seat and adjustable handlebars accommodate growing riders up to 150 lbs, extending the useful life well beyond a single season. The Li-Ion chemistry holds charge longer and delivers more consistent voltage than lead-acid alternatives.

Frequently Asked Questions
Consider what you avoid: no gas, no oil, no spark plugs, no two-stroke mix. A gas-powered bike at a similar price point costs more to operate every single month. The Li-Ion battery charges from a standard outlet, and the 14-mile range means full afternoons of riding between charges. At $439, you are paying once for years of trail riding with minimal maintenance overhead. That is the math that matters.
Every product we carry is vetted before it earns a listing. We are not a marketplace dumping ground where incompatible or underperforming products hide behind thousands of reviews. When you buy from Off Grid Vault, you get a 30-day performance guarantee — if it does not perform as specified, we make it right. Our team actually knows the products, and you can reach a human who understands what you bought. That accountability does not exist on generic marketplace platforms.
The three-speed key lock is designed exactly for this scenario. Lock the bike to 5 MPH while your rider learns throttle control and braking basics on the variable twist-grip. The padded seat, adjustable handlebars, and 150 lb weight capacity mean they will not outgrow it in one season. Front and rear disc brakes provide forgiving, consistent stopping power. Start slow, build confidence, then unlock higher speeds when they are ready. The full suspension handles the inevitable mistakes.
Charge time depends on the charger used, but a standard Li-Ion charger for a 36V 8Ah battery typically completes a full charge in 4 to 6 hours. The onboard battery meter lets you monitor charge level during rides so you are not guessing when it is time to head back. With up to 14 miles per charge in optimum conditions, most riders get a full afternoon of trail riding before needing to plug in.
The 790-watt rare earth neodymium motor delivers instant torque without warm-up, hesitation, or carburetor tuning. The steel frame matches the durability of gas-frame construction. Where the Demon pulls ahead is maintenance: no oil changes, no air filters, no fuel stabilizer for winter storage, no spark plug replacement. The Li-Ion battery is lighter than a lead-acid equivalent and delivers consistent voltage through the full discharge cycle. Disc brakes front and rear match or exceed what you find on comparable gas models. This is not a toy — it is a field-tested dirt bike without the gas headache.
Some assembly is required — this is standard for shipped dirt bikes to prevent damage in transit. The steel frame, suspension, motor, and drivetrain arrive pre-built. You will need to attach the handlebars, front wheel, and make final adjustments. Basic tools are all that is needed. If you have questions during assembly, contact our team — we stand behind what we sell and will help you get your rider on the trail.
