The JK 284 is a medium-high range electro-magnetic 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 32 resistance levels.

Technical features
The JK 284 exercise bike, thanks to its wide range of adjustments, can accommodate tall people on board; the data for the height adjustment of the saddle on 9 positions (leg measurement from 67 cm to 91 cm) and in depth 8 cm confirm this good capacity. 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.
