What Makes the Ace Demon eBike So Special?
The ace demon ebike, officially known as the ACE-X Demon Dual Motor Fat Electric Bike from Ampd Bros, is an Australian-engineered powerhouse that’s built for those who demand more from their rides. Launched by the family-owned Ampd Bros in 2019, this model has quickly gained a reputation for its iconic “X” frame design, which not only looks sleek but also provides exceptional stability and strength. Unlike standard e-bikes, the ace demon ebike is equipped with dual 1,000W Bafang hub motors—one in the front and one in the rear—delivering a combined 2,000W of power. This all-wheel-drive setup ensures superior traction, especially on challenging terrains like hills, sand, or mud.
What sets the ace demon ebike apart is its focus on versatility. It’s road-legal in Australia with a restricted top speed of 25km/h, but for private property use, you can unlock it to reach up to 50km/h. The bike’s fat 20×4.0″ Vee Tire Huntsman puncture-resistant tires make it ideal for all-terrain adventures, while the dual suspension system absorbs shocks for a smoother ride. Whether you’re a solo rider or bringing along a passenger on the spacious two-person seat, the ace demon ebike handles it all with ease. Priced at around $5,290 AUD, it’s a premium investment, but one that comes with a 2-year warranty on the bike and 1-year on the battery, backed by nationwide support from over 70 locations.

Key Features of the Ace Demon eBike
Let’s break down the features that make the ace demon ebike a top choice for e-bike enthusiasts. Starting with the heart of the machine: its dual motors. Each motor provides 95N.m of torque, totaling 190N.m, which translates to effortless hill climbing—up to 30° or 60% inclines with pedal assist. You can switch between front, rear, or both motors depending on your needs, optimizing for power or efficiency.
The suspension is another highlight. The front independent suspension and rear adjustable DNM setup offer 100mm of travel, ensuring comfort on bumpy paths. Paired with Tektro 4-piston hydraulic disc brakes featuring 203mm discs and electronic brake cut-off, stopping power is reliable even at high speeds. The Shimano 7-speed drivetrain, complete with a Rapid Fire Micro Shifter and Altus derailleur, allows for crisp gear changes, making it feel more like a traditional mountain bike with an electric boost.
Comfort isn’t overlooked either. The custom large quilted plush dual seat measures 600mm long, perfect for two riders, and the seat height is adjustable from 850mm to 950mm. An adjustable coffee cup/bottle holder adds a practical touch for long rides. The large color LCD display provides all essential info at a glance—speed, battery level, odometer, and more—with advanced options like parental controls for speed limiting.
Safety features include an upgraded PRO front LED headlight with 1,700 lumens and daytime running lights (DRL), plus integrated rear LED brake lights in the battery pack. The aluminum frame is rust-resistant, and the bike comes with matte black aluminum fenders, a kickstand, and a basic tool kit. Optional accessories like a cargo rack, kids’ seat kit, or GPS tracker expand its utility for family outings or errands.

Technical Specifications: A Deep Dive
To truly appreciate the ace demon ebike, let’s examine its specs in detail. The bike is powered by a removable 52V 25Ah Samsung Premium 21700 Lithium battery, which uses cells 30% larger than standard for better efficiency and longevity. Charging takes about 8.5 hours with the included 3A charger, or faster with an optional 5A model. The range is impressive—up to 100km+ on a single charge when using one motor, though this varies based on terrain, rider weight (max 180kg), and usage.
The overall dimensions make it substantial yet manageable: 1,800mm long, 660mm handlebar width, and a wheelbase of 1,160mm. Ground clearance is 270mm, ideal for off-road, and it’s suited for riders up to 200cm tall. The bike weighs 52kg with the battery, so it’s not the lightest, but the power makes up for it.
Ride modes include pedal assist (adjustable levels 1-5, or customizable to 1-3/1-9), walk mode (up to 6km/h), and an optional throttle mode for off-road thrills. The Ampd Bros custom controller handles up to 1,600W peak power per motor, ensuring smooth operation. Colors available include Bronze Eclipse, Titanium Eclipse, Matte Black, Thunderbolt, and Galaxy, allowing you to pick a style that matches your personality.

Performance and Real-World Testing
In terms of performance, the ace demon ebike shines in field tests. YouTube reviews show it conquering 20% inclines (10 degrees) with ease, where single-motor models like the Ace Pro struggle. First impressions from unboxing videos highlight its “packed with power” feel, with dual motors providing instant acceleration that puts a smile on riders’ faces. Off-road, the fat tires and suspension handle rough terrain smoothly, while on pavement, it cruises effortlessly.
Battery life holds up well in real use—one user clocked over 200km in six weeks without issues, praising its fun factor. However, for taller riders (over 188cm), the pedaling position might feel a bit cramped, like a BMX, but it’s still enjoyable.
