Jk Fitness Spin Bike JK544

Sophisticated design, sturdiness, and optimal performance—these are the key concepts that make the new JK 544 indoor bike one of the most attractive spin bikes on the market today! The new JK 544 further enhances JK Home Fitness's mid-to-high-end offering, expanding the category of high-performance magnetic spin bikes with a fixed-gear manual braking system and silent belt drive. All this comes in a completely new design, featuring a sturdy yet streamlined frame that's decidedly more attractive and sporty thanks to its new matte black look and red accents.

The new JK 544 is a mid-to-high-end magnetic spin bike in the home fitness world. It features a large inertial system with a 22 kg flywheel (balanced flywheel) and a manually adjustable magnetic brake with micrometric variable intensity. Pedaling on the new JK 544 spin bike is extremely smooth and powerful, even at high resistance levels, offering even the most demanding users a wonderful experience. For optimum comfort, the JK 544 indoor bike features 12-position saddle height adjustment (fits leg sizes from 73.5 cm to 99.5 cm) and a 7.5 cm seat depth. The multi-grip handlebar, covered in dipping leather with low, chrono grips, can be adjusted to 8 height positions and 8 cm depth. These extensive adjustments allow for the best riding position for every user, even the tallest! The anatomical racing-design saddle, with a central cutout, helps improve the sensation on board, ensuring comfortable, long rides without any particular discomfort. The non-slip aluminum racing pedal with SPD quick release and foot strap helps maintain correct support of the shoe in all phases of pedaling, even the most intense ones.

Training Tracking

The cycle computer with a large multi-information LCD display is integrated into the console with a cell phone/tablet holder and allows you to monitor all your cardio training parameters, such as time, distance, speed, RPM, calories, watts, and heart rate. The JK 544 gym bike is equipped with a sensor in the console to detect the user's heart rate via the heart rate monitor during more intense cardio workouts; the heart rate monitor is included as standard.

Interactive training

The new JK 544 indoor bike with built-in receiver can connect to the most important fitness apps (Zwift – Kinomap) to make training interactive, for passionate online challenges with friends or simply while pedaling around the streets of the world.

Practicality and comfort
