Jupiter Defiant: The Portable 2-Wheel ATV

Unmatched Off-Road Power in a Convenient Folding Design

The Jupiter Defiant is built for those who want to dominate any trail without needing a massive storage space. Described as a 2-wheel ATV , this bike features high-volume 4" x 20" Kenda Krusade fat tires that allow you to power through snow, sand, and mud with ease. Despite its "beastly" performance, the Defiant folds down in 3 easy steps , making it a perfect companion for your RV, boat, or small apartment.

Versatile Range and Speed

Equipped with a 48V 10.4Ah battery , the Defiant offers a range of approximately 25 miles on throttle alone, while pedaling riders can achieve upwards of 60 miles . The variable speed twist throttle provides power on demand, pushing the bike to speeds of up to 28 mph , while the 5-level Pedal Assist system allows you to customize your effort level for every journey.

Refined Utility and Safety

Concealed Removable Battery: The battery is hidden within the center frame for a sleek look and added protection. It locks with a key and can be removed for convenient indoor charging.

Premium Comfort Seating: Every Defiant comes stock with the JupiterBike Upgrade Seat , featuring dual spring suspension, a breathable mesh top, and an integrated 3-mode LED taillight.

7-Speed Shimano Drivetrain: A Shimano Tourney derailleur paired with a thumb shift lever ensures rapid, precise gear changes when you choose to pedal manually.

Rugged Build: With a quick-release front wheel and an optional aluminum alloy rear cargo rack , this bike is as practical for the daily commute as it is for weekend trail exploration.
