Built in 2023 with a solid aluminum frame and a compact folding design, this model offers a balance of strength and convenience. 

Detailed Specs & Features

The heart of the Jupiter Defiant ST lies in its Motor Power and battery prowess. It sports a robust 750W rear hub motor, with a peak output pushing 1130 watts, which facilitates quick acceleration and confident hill climbing up to a 25-degree angle. This is significant for urban terrain that often includes inclines, reflecting the bike's engineering for real-world challenges. 

Powered by a 48-volt Lithium-ion battery with a capacity of 633.6 Wh, it promises a considerable range of 30 to 50 miles on a single charge, fitting daily commute requirements comfortably. Charging is efficient with a 5-hour cycle supported by a 100W charger, and its removable battery design adds flexibility for indoor charging or security. The continuous power rating matches the motor power at 750W, maintaining a steady ride without overheating, thanks to built-in heat protection and overheat safeguards. 

The bike's 3.5-inch LCD, mounted centrally, offers clear visibility of speed, battery level, trip data, and assist modes, enhancing usability at a glance. The drivetrain complements this with a Shimano Altus 7-speed system, coupled with a chain drive equipped with a guard for cleaner operation. Its hydraulic disc brakes with 7.1-inch rotors ensure reliable stopping power, while safety certifications from UL/CE add a layer of trust. This bike integrates foldability for storage ease, and the frame's step-thru style allows simple mounting, suited especially for urban riders needing flexibility.

Design & Build

Crafted with lightweight aluminum, the Jupiter Defiant ST weighs just 75 pounds, a commendable feat for a foldable EBike with this power class. Its step-thru frame style supports easy mounting and dismounting, targeting unisex adult riders with a recommended age of 16 and above. 

The black and white color options provide classic choices, and integrated ergonomic features like a riser handlebar and comfort foam saddle with suspension contribute to rider ease. This bike also includes a side-mounted kickstand and rear rack that enhance practicality, especially for cargo or errands, making it a versatile city companion.

With five pedal assist levels plus a thumb throttle option, riders can fine-tune their ride experience depending on terrain or energy conservation needs. 

Cruise control adds convenience for longer stretches of flat ground, while walk assist mode eases handling when pushing the bike manually. The torque rating of 80 Nm indicates ample power for inclines, backed by a motor efficiency of 85%.
