The KOOLUX X16 is a practical and versatile folding fat tire electric bike designed for daily commuting, weekend adventures, and easy storage in small apartments or car trunks. Powered by a 500W brushless rear hub motor that delivers 50-60 Nm of torque, it offers a smooth and responsive ride with a top speed of 25 km/h (which can often be unlocked higher depending on local regulations). Its 48V 15.6Ah removable lithium-ion battery (made with 18650 cells) provides an impressive range of 70-150 km per charge depending on the level of pedal assist, rider weight, terrain, and riding style, with a full charge taking approximately 5.5 hours.

The bike features a sturdy yet lightweight aluminium alloy frame that folds down to a compact size of 91 × 38 × 74.5 cm, while the unfolded dimensions are 164 × 56 × 120 cm, making it highly portable despite its 45.6 kg gross weight. It is equipped with 20-inch fat tires (20 × 3" solid puncture-resistant tires) that deliver excellent stability, grip, and comfort on various surfaces including sand, snow, or rough roads. The 7-speed gear system combined with pedal assist and throttle modes allows riders to tackle hills and longer distances comfortably, while the front and rear double disc brakes provide reliable stopping power.

Additional thoughtful features include an adjustable seat, rear carrier rack for carrying loads up to 120 kg total capacity, LED display for monitoring speed and battery level, and a turn-the-switch starting mode. The removable rear carrier battery makes charging convenient, and the overall design emphasizes portability, durability, and everyday usability, positioning the X16 as a capable all-rounder folding e-bike from the brand KOOLUX.
