Observations
  • The Sonic Stomper SS is a premium high-performance cruiser electric bike that combines the style and comfort of a cruiser with performance and aesthetic influences from the worlds of Motocross and BMX

  • Performance is the name of the game here with massive amounts of power from the Bafang 1000-watt mid-drive motor, smooth shifting and riding experience from the Sturmey Archer powered drivetrain, and stellar stopping power thanks to TRP Zurich hydraulic disc brakes with quad-piston calipers and 203mm rotors

  • This Ebike is hand-built in Tempe Arizona and is visually stunning thanks to clean internal routing of all cabling, seamless integration of the battery in the downtube, a plethora of color options that include a color-matched cupholder, and countless other unique design touches

  • The performance focus means a lack of convenience and utility features such as racks, fenders, or integrated lights, this is also a large and heavy bike at 72 pounds and the steep price point may be discouraging for some buyers
