Brand New - Diamond Cardio
INDOOR CYCLE JK 534 (serie JK FITNESS HOME FITNESS) - JK534

Design, performance and special technical details that project the new JK 534 indoor bike among the most interesting spin bikes on the market to date! Born from an innovative project, the new JK 534 confirms the medium-high home fitness offer by expanding the category of electro-magnetic spin bikes with fixed-gear silenced belt drive with a motorized brake system that simulates the ratios of a racing bike; all this inserted in a completely new look, out of the usual stylistic canons of spinning bikes, decidedly more modern and sporty thanks to the new black/silver matt look.

Technical features

The new JK 534 is a mid-range electro-magnetic spin bike in the home fitness world that mounts a major inertial system with a flywheel mass of 20 kg (balanced flywheel), an electronically controlled magnetic brake that generates a maximum power of 550W (220W at 60 RPM), and a 17-cm crank. The JK 534's brake unit is electronically managed by a servo motor 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 gearbox, for pedaling pleasure out of the classic box. The pedaling of the new JK 534 spin bike is always smooth and jam-free at all paces, always offering beautiful sensations to the user who climbs aboard. For optimum comfort, the JK 534 indoor bike has micrometric saddle height adjustment from 155 to 195 cm on 12 positions (leg size from 73 cm to 100 cm) and depth adjustment 10 cm, the “gravel” racing bike style handlebars covered with racing tape, adjust in height from 155 to 195 cm. These adjustments allow every user to always find the best position in the saddle, even very tall people! The racing saddle design, anatomical, with central hole and pro padding, helps and improves the feeling on board ensuring comfortable and long rides without discomfort. The non-slip big-size aluminum racing pedal with foot stopper strap helps maintain proper shoe support during all phases of pedaling, even the most intense ones.

Training monitoring

The cycle-computer with a large multi-information LCD display is built into the console with an adjustable mobile phone/tablet holder, allows you to keep track of all cardio workout parameters, such as: time, distance, speed, average speed, RPM, calories, Watts, heart rate, gear/resistance level, and gear/sprocket 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 training sessions; the heart rate monitor is optional to be purchased separately.

Interactive workout

The new JK 534 indoor bike with built-in receiver can connect to the world's leading fitness APPs (Zwift - Kinomap) to make training more fun, pedaling around the world or challenging friends on virtual tracks online, while staying in the comfort of your own home!

Practicality and comfort

The sturdy steel frame of the JK 534 rests on wide outriggers with four non-slip feet (4 self-levelling pads) and allows it to support a maximum user weight of 130 kg, while at the front there are two practical transport wheels, which allow easy movement of the JK 534 spin bike from one room to another. The new JK 534 fitness bike is a magnetic spin bike that weighs 38 kg and measures 130 x 65 cm H 126 cm; the perfect cycling companion for those who want performance, design and multimedia in the same product. JK Fitness offers the best spin bikes on the market with perfect value for money.
