Technical features

The new JK 514 is a mid-range magnetic spin bike in the home fitness world with fixed gear transmission and a silent belt, equipped with an inertial system with a 18 kg flywheel mass (balanced flywheel) and a 16.5 cm crank arm, which generate fluidity in pedalling at all resistance levels. Resistance is adjusted via a manual selector control with "micrometric" resistance, which also acts as an emergency brake in case of sudden stops by the user. For greater comfort, the JK 514 indoor bike has saddle height adjustment in 8 positions (leg measurement from 73.5 cm to 89 cm) and depth adjustment of 6 cm, and the handlebar adjusts in height in 8 positions; these adjustments serve to find the correct riding posture for each user. The racing design saddle, anatomical and with a central hole, helps and improves the on-board sensation for all users, ensuring comfortable and long rides without discomfort. The non-slip iron racing pedal with toe strap helps maintain proper foot placement during all phases of pedalling, even the most intense ones.

Workout monitoring

The cycle computer with a multi-information LCD display also features a mobile phone/tablet holder and allows real-time monitoring of all workout parameters, such as: time, distance, speed, RPM, calories, and heart rate.
