Jupiter Defiant ST Black Fat Tire Folding Electric Bike 750W, 48V, 13.2Ah, hydraulic brakes, full suspension, max speed 28mph - Financing Available
Jupiter Defiant ST: The Premium All-Terrain Folder
Unmatched Accessibility, Maximum Power
The Jupiter Defiant ST is engineered for riders who want a "go-anywhere" bike without the struggle of a high step-over frame. It features a full suspension system—with both front and rear shocks—that works alongside 20" x 4" fat tires to glide over sand, snow, and rough trails. Despite its rugged capabilities, the Defiant ST remains seriously portable, featuring a quick-release front wheel and a center-folding frame for easy storage in an RV, boat, or car trunk.
High-Torque Performance for Every Ascent
Dominate steep hills and challenging terrain with the 750W geared hub motor (peaking at 1130W). This ultra-powerful motor is paired with an upgraded 48V 13.2Ah Samsung battery, providing enough energy for adventures up to 50 miles on a single charge. The concealed battery locks securely into the frame but can be easily removed for convenient charging or storage.
Premium Components for Total Control
-
Dual Hydraulic Disc Brakes: Experience superior, responsive stopping power with dual 160mm hydraulic brakes that offer reliable control in all weather conditions.
-
Upgraded Comfort Features: Every touchpoint is refined, from the leather comfort grips to the dual-spring comfort saddle featuring a breathable mesh top and an anatomical opening for long-distance relief.
-
All-Weather Utility: Standard equipment includes front and rear mudguards and a heavy-duty MIK-compatible rear cargo rack, making it as practical for the daily commute as it is for off-road exploration.
-
Shimano 7-Speed Drivetrain: A 7-speed Shimano Altus derailleur with a paddle shifter gives you the flexibility to pedal efficiently across a wide range of speeds and inclines.

Frequently Asked Questions
What is the benefit of the Step-Through (ST) frame?
The ST frame allows for easy mounting and dismounting by lowering the crossbar height. This is perfect for riders who have limited mobility, those wearing work clothes, or anyone who wants a more accessible feel without sacrificing the "Defiant" power.
How does the full suspension affect the ride?
While many folding bikes have no suspension or only front shocks, the Defiant ST features a "Dual Shock" system. The front and rear suspension work together to absorb the impact of large bumps and potholes, reducing rider fatigue and keeping the tires planted for better traction.
Can I ride this bike in the rain?
The Defiant ST is rated IP54 water-resistant, meaning it is safe to ride in rain and through light spray. However, you should avoid high-pressure washing or submerging the motor and battery in deep puddles.
What is an MIK-compatible rear rack?
MIK is a standardized mounting system for bicycle accessories. It allows you to quickly "click" bags, baskets, and crates from various brands onto your rear rack securely without needing straps or bungee cords.
Is the front wheel really quick-release?
Yes. You can remove the front wheel in seconds without tools. This is a huge advantage for fitting the bike into tighter spaces or smaller trunks when the frame is already folded.
How does the 100% online financing work?
Select our financing partner at checkout for a quick application. You'll receive an instant decision, allowing you to split the cost of your Jupiter Defiant ST into low monthly payments.
