The "20-inch Powerhouse."
The Wired Viper is the compact, step-through sibling to the legendary Wired Predator. While it shares the same high-performance DNA, the Viper utilizes a smaller wheel platform to achieve what Wired claims is the highest torque output of any Power Performance Bike (PPB) on the market. It is designed for riders who want elite-level power in a more accessible, maneuverable frame.
Key Performance Specs
- Powertrain: Dual-motor 72V All-Wheel Drive (AWD)
- Peak Power: 8000W
- Top Speed: 50+ MPH
- Torque: 430Nm (Combined)
- Battery: 72V Dual Battery System
- Price: $3,699 MSRP
The "Physics" of Power
The standout feature of the Viper is its 20-inch wheel platform. Because it uses the exact same motors, controllers, and 72V batteries as the larger Predator but pairs them with smaller wheels, it gains roughly 30% more effective torque at the ground. This results in explosive off-the-line acceleration, surgical low-speed control, and industry-leading hill-climbing capabilities.
Design & Build
Unlike many high-performance bikes that require a high stand-over height, the Viper features a step-through frame. This makes it a "confidence-inspiring" option for a wider range of rider heights without sacrificing the "brutality" of the AWD system. It is positioned not as a "mini" bike, but as a refined, more compact version of Predator-class power.
Important Considerations for Buyers
- Classification: Wired classifies this as a Power Performance Bike (PPB) rather than a traditional e-bike. Due to the 50+ MPH top speed and 8000W output, it exceeds standard Class 1, 2, or 3 e-bike regulations in many jurisdictions.
- Availability: Currently available for pre-order
- Support: Wired is an American-owned company headquartered in Mundelein, Illinois, providing U.S.-based customer support.
The Verdict (Pre-Review)
The Wired Viper is built for the "torque junkie." It’s a niche machine that prioritizes mechanical leverage and traction over all else. If you are looking for a step-through that can out-climb almost anything on two wheels and hits 50 MPH, the Viper stands alone in its category.
The Freshly Charged Take
The Wired Viper is an exceptionally high-performance 20x4 fat tire eBike that blurs the line between a traditional bicycle and an electric motorcycle. Featuring massive 72V 35Ah batteries and a dual-motor system capable of an 8,000W peak output, this "compact monster" can reach speeds of over 55 mph with acceleration so aggressive it can easily trigger wheelies. Despite its raw power, the bike offers a premium and stable ride thanks to high-end components like an Exsho Cowboy dual crown fork, 4-piston hydraulic brakes, and a highly customizable display that allows riders to tame the motor behavior. While it is likely too heavy and "unhinged" for beginners or casual commuters, the Viper stands out as a top-tier choice for adrenaline seekers who want maximum torque and long-range performance in a smaller, step-through frame.
