The JK 274 is a medium-high range electromagnetic exercise bike in the home fitness world equipped with a 12 kg balanced flywheel mass and a 17 cm chromed crank, which allows for very smooth and jerk-free pedaling at any resistance; the effort is adjusted by a servo motor controlled by the console with 16 resistance levels.

Technical features
The electronically adjustable magnetic brake unit allows you to reach a maximum power of 431 W and a power of 255 W at 60 RPM. The JK 274 exercise bike, thanks to its wide range of adjustments, can accommodate very tall people on board; the data on the height adjustment of the saddle on 10 positions (leg measurement from 64 cm to 94.5 cm) and in depth 10 cm confirm this ability. The handlebars can also be adjusted in depth and inclination, to allow each user to find the correct exercise position once they get on the exercise bike. The saddle used is ergonomic with graduated compression padding that helps maintain the right position in the saddle for long rides, ensuring pleasant workouts in full comfort. The self-leveling non-slip pedal with foot strap helps maintain the correct position of the foot and leg in all phases of the exercise.

Interactive training
The new JK 274 exercise bike with built-in receiver can connect to the most important fitness APPs (Zwift – Kinomap) to make cardio training more fun, pedaling around the world! The console with a convenient mobile phone/tablet holder, is equipped with a backlit multi-display color screen with 5 windows plus a 10 x 8 pxl graphic matrix (to view the program profile); the data provided by the display are: time, distance, speed, RPM, calories, Watts, heart rate, resistance level, program number, program diagram.

Training Tracking
The new JK 274 exercise bike is also equipped with a series of programs to make training in the saddle more motivating; 1 manual program managed directly by the user, 10 preset programs with different resistance profiles applied for each segment, 4 HRC programs (55% 75% 95% tag user BPM), 1 constant Watt program, 1 recovery test (on the user's recovery after exertion). The JK 274 exercise bike is equipped with grip pulse sensors on the handlebars and an integrated sensor for receiving from the heart rate monitor to detect the user's heart rate during the most intense training sessions; the chest heart rate monitor is an optional extra to be ordered separately.

Practicality and comfort
The sturdy frame of the JK274 rests on large stabilizers with 4 rubber feet (self-leveling rear) that can support a maximum user weight of 130 kg; 2 transport wheels are positioned at the front, which facilitate the user in moving from one room to another. The JK 274 exercise bike is a magnetic exercise bike that weighs 30.5 kg and is compact 103 x 52 cm H 135 cm; practically perfect for those who want excellent performance but do not have large spaces. A perfect ally for those looking for an exercise bike to lose weight or who want to do a cardio workout and enjoy the benefits of the exercise bike.
