Jk Fitness Spin Bike JK534

Design, performance, and unique technical details make the new JK 534 indoor bike one of the most interesting spin bikes on the market today! The new JK 534 is an innovative project that confirms the mid-to-high-end home fitness offering by expanding the category of electro-magnetic spin bikes with a silent fixed-gear belt drive and a motorized braking system that simulates the gear ratios of a racing bike. All this comes in a completely new look, far removed from the usual stylistic canons of spinning bikes, decidedly more modern and sporty thanks to the new matte black/silver look.

The new JK 534 is a mid-range electro-magnetic spin bike in the home fitness world. It features a significant inertial system with a 20 kg flywheel (balanced flywheel), an electronically controlled magnetic brake that generates a maximum power of 550 W (220 W at 60 RPM), and a 17 cm crank. The JK 534's braking system is electronically controlled by a servomotor controlled by buttons on the console and levers on the handlebars (racing bike style) that simulate the resistance of a 3 x 8-speed MTB gear shift, for a truly enjoyable ride. The new JK 534 spin bike's pedaling is always smooth and smooth at all speeds, offering users a wonderful experience every time they step on board. For optimal comfort, the JK 534 indoor bike features micrometric saddle height adjustment from 155 to 195 cm in 12 positions (for leg measurements from 73 cm to 100 cm) and a 10 cm depth adjustment. The racing bike-style "gravel" handlebars, covered with racing tape, can be adjusted in height from 155 to 195 cm. These adjustments allow every user to always find the best riding position, even the tallest! The anatomical racing-design saddle, with a central cutout and pro padding, helps improve the sensation on board, ensuring comfortable and long rides without discomfort. The non-slip, big-size aluminum racing pedal with a toe strap helps maintain correct support of the shoe during 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 an adjustable phone/tablet holder. It allows you to monitor all your cardio training parameters, such as time, distance, speed, average speed, RPM, calories, watts, heart rate, gear/resistance level, and chainring/pinion ratio. The JK 534 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 an optional accessory and must be purchased separately.

Interactive training

The new JK 534 indoor bike with built-in receiver can connect to the most important fitness apps (Zwift – Kinomap) to make training more fun, pedaling around the world or challenging friends on virtual online tracks, from the comfort of your home!

Practicality and comfort

The sturdy steel frame of the JK 534 rests on large stabilizers with four non-slip feet (four self-leveling pads) and can support a maximum user weight of 130 kg. Two practical transport wheels are located at the front, making it easy to move the JK 534 spin bike from one room to another. The new JK 534 fitness bike is a magnetic spinning bike that weighs 38 kg and measures 130 x 65 cm x 126 cm; the perfect pedaling companion for those who want performance, design, and multimedia in the same product. JK Fitness offers the best spin bikes on the market with an excellent quality/price ratio.
