BikeRide finds and shows you the best prices of the bikes you want to buy. Prices constantly change and it’s impossible to compare them all yourself.

We search for prices on over 120 bike retailers to guarantee that we find the lowest prices – to save you time and money.

It’s a promise we stand behind: If you find a lower price on a bike elsewhere, we will sell it to you for 10% less. For example, if you find a bike for $480 that we have listed at $500, we will offer you to buy it for $432 through BikeRide. The bike must be the same color and size, sold in the US and not include the use of a coupon.

If you find a lower price, email us at [email protected] with documentation of the price. We’re committed to making sure that the cost of a bike does not keep you from cycling!

Summary of Reviews

We have read all expert and user reviews on the Wired Viper. In summary, this is what cyclists think. Updated Jul 15, 2026 by Amar Punekar.

14 reasons to buy

  • Testers relish the strong acceleration and impressive speed, reaching up to 56mph.
  • In testing, the Viper climbs steep inclines with extreme ease using throttle-only.
  • Riders can switch between using the front, rear, or both motors at the push of a button.
  • Experts say the full suspension and 4” wide tires make for a comfortable ride over bumpy pavement and light off-road terrain.
  • The four-piston Gemma hydraulic brakes (203mm rotors) deliver good stopping power.
  • The Viper has a headlight, a taillight with brake activation, front and rear turn signals, fenders, and a rear rack rated for 121lb.
  • Users can customize throttle power, starting strength, and power output for each PAS level via the display.
  • The Viper has switchable torque and cadence sensors.
  • Testers reach up to 35mph with pedal assist thanks to the large 56t chainring and 11-34t cassette.
  • Reviewers say the handling is stable even at high speeds.
  • The display can be read through polarized sunglasses and includes a USB-C charging port.
  • Experts appreciate the DNM air shock’s adjustability.
  • The Viper comes with two seatposts of different lengths.
  • The two 3.5A chargers result in quick charging times.

6 reasons not to buy

  • Accelerating with the throttle on the highest power setting causes the front wheel to lift.
  • At 160lb, the Viper is heavy, even for a dual-motor, dual-battery e-bike.
  • A tester complains of loud noise from both motors, especially at high speeds.
  • The Viper's speed and power make it an electric motorcycle requiring a driver's license, DMV registration, and insurance.
  • A tester complains of pedal scrapes due to the low ground clearance.
  • Wired doesn't provide an online user manual for this bike.

Bottom line

How much power can you fit into a 20” fat-tire e-bike? Well, the 3,500W Wired Viper reaches 56mph on the flat and easily rides up steep inclines at high speeds. The reliable brakes, dual-battery capacity, switchable sensors, and ride customization options please testers who find it comfortable over light off-road terrain. Throttle power is too aggressive in its highest setting (this is customizable), and the bike is extremely heavy, meaning it isn’t suited for commuters and casual riders, but for speed junkies who are happy to register and insure it.
