Product Description

The G50 is the bike that handles the unglamorous parts of daily life — the commute, the errand run, the quick trip across town — and does it well enough that you stop thinking about it. A 1500W peak motor and 48V 18Ah battery deliver up to 68+ miles of range, 20-inch fat tires hold their line on wet pavement and gravel, and at 75 lbs it's the lightest, easiest-to-handle bike in the HappyRun lineup. It's also UL listed and street legal, which matters more than most spec sheets let on.

  • 1500W peak motor (750W rated), up to 68+ miles range — efficient power for city commuting, cargo runs, and mixed-surface riding
  • 48V 18Ah battery, 30–68+ miles range — range varies with assist level and terrain; enough for full-day urban use on one charge
  • UL listed and street legal — meets US safety standards for road use; check your local e-bike classification requirements before riding
  • 20-inch fat tires with full suspension — wide tires and front/rear suspension absorb road imperfections and hold grip on wet or uneven surfaces
  • Quick-release wheels — simplifies storage, transport, and maintenance without tools
  • 7-speed gear system + LED headlight + LCD display — manual gear control, integrated lighting, and clear ride data in one package
  • 75 lbs bike weight — the lightest bike in the HappyRun lineup; ships free to the contiguous US
