RS-A02 Pro
Model year 2025
Price and specs last reviewed Jul 17, 2026
The SAMEBIKE RS-A02 Pro is a folding fat-tire e-bike built for snow, sand, and rough trails: an 80+ Nm hub motor and dual suspension (front fork plus rear shock) handle grades up to about 20 degrees, while 20x4-inch tires add float and grip on loose surfaces. The removable 48V 15Ah battery is rated for a manufacturer-claimed 68 miles, closer to 44 miles in real-world mixed-assist riding, with a 330 lb payload capacity. Mechanical disc brakes, a 4-inch color LCD, and an IP54-rated frame (IP64 for the motor, battery, and display) round out a bike built to fold down for car-trunk storage between off-road trips. At $959, it is the entry point into SAMEBIKE's RS-A02 line, one step below the higher-torque RS-A02 Plus.
