Refined design, sturdiness and optimal performance, these are the basic concepts that push the new JK 544 indoor bike among the most interesting spin bikes on the market today! The new JK 544 confirms the medium-high JK home fitness offer by expanding the category of high-performance magnetic spin bikes with manual braking system, fixed gear and silenced belt transmission; all this inserted in a completely new guise, with a sturdy frame that is decidedly more attractive and sporty thanks to the new black matt look and red details.

Technical features
The new JK 544 is a medium-high range magnetic spin bike in the home fitness world that features a significant inertial system with a flywheel mass of 22 kg (balanced flywheel), a manually adjustable magnetic brake with variable “micrometric” intensity. The pedaling of the new JK 544 spin bike is extremely fluid and full even at high resistances, offering wonderful sensations to the user, even the most demanding. For excellent comfort, the JK 544 indoor bike has a saddle height adjustment of 12 positions (leg measurement from 73.5 cm to 99.5 cm) and a depth of 7.5 cm, the multi-grip handlebar covered in dipping with low crono grips, can be adjusted in height to 8 positions and in depth 8 cm; these wide adjustments allow you to always find the best position on the saddle for each user, even very tall people! The racing design saddle, anatomical, with central hole, helps and improves the sensation on board, ensuring comfortable and long pedaling without particular discomfort. The non-slip racing pedal in aluminum with SPD quick release and foot strap helps maintain the 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 inserted into the console with a mobile phone / tablet holder and allows you to keep track of all the parameters of the cardio training, such as: time, distance, speed, RPM, calories, Watts, 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 training sessions; the heart rate monitor is offered as standard.

Interactive training
The new JK 564 indoor bike with built-in receiver can connect to the most important fitness APPs (Zwift – Kinomap) to make training more fun, for passionate online challenges with friends or simply pedaling around the world!

Practicality and comfort
The sturdy steel frame of the JK 544 rests on imposing stabilizers with 4 self-leveling pads and can support a maximum user weight of 150 kg, while at the front there are two practical transport wheels, which allow easy movement of the spin bike after use. The new JK 544 fitness bike is a magnetic spinning bike that weighs 58 kg and measures 120 x 52 cm H 131 cm; the best pedaling companion for those who want high performance, robustness and multimedia in the same product.
