Product Description

The G50 is the everyday bike — the one that handles the commute, the errand run, and the occasional trail without asking you to compromise on any of them. A 1500W peak motor, 48V 18Ah battery with up to 68+ miles of range, and 20-inch fat tires that hold their line on wet pavement and gravel alike. UL listed and light enough at 75 lbs to actually move when you need to. This is the bike that earns its place in your daily routine.

  • 1500W peak motor (750W rated), up to 68+ miles range — efficient power delivery for city commuting, cargo runs, and mixed-surface riding
  • 48V 18Ah battery, 30–68+ miles range — range varies with assist level and terrain; sufficient for full-day urban use on a single 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 maintain grip across wet, loose, 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 a single, well-organized package
  • 75 lbs bike weight — the lightest bike in the HappyRun lineup; ships free to the contiguous US
