The S4K is a user friendly indoor training bike with a very competitive price tag. It offers all of the important features that you would find on the high end spin bikes used in your gym classes at a fraction of the price.
To ensure a correct riding position is obtained the S4K has a height adjustable handlebar and a 2 way adjustable seat position. Having the bike set up correctly is vital for a successful workout as it reduces strain on the knees and being comfortable will also enable you to train for longer.
The tension is controlled by a simple turn of the tension knob. This works the same way as the gym studio bikes in that it applies friction to the flywheel and it also doubles as an emergency brake when pressed down.
Just like the bikes in the gym the flywheel gearing is fixed meaning that the flywheel and pedals are directly connected allowing you to really build up the cadence even when you test yourself with higher tension settings. The 13kg flywheel is belt driven which is quieter than a chain driven system. This can be an important factor for home use equipment. The flywheel is heavy enough to allow for a smooth pedalling motion even when stood up but light enough to make moving the bike using the transportation wheels on the front stabiliser an easy task.
The handles on the S4K offer multiple hand positions as mentioned earlier it is important to be in the correct position when pedalling and you need different hand positions when seated flat standing run hover seated or doing standing climbs sprints jumps 1st 2nd & 3rd hand positions are all possible.
Straps and toe clips are fitted to ensure your feet are securely connected to the pedal this ensures correct foot position on the pedal and makes it easier to build up speed using the ball of your foot. For serious training SPD pedals can easily be fitted to the bike.
The computer has a large screen and is situated between the handlebars for easy reading during the workout and offers workout feedback of time distance pulse speed calories or scan.
If you enjoy bike riding and you’re looking for an easy non impact way to exercise at home nothing comes as close to the cycling experience or is as effective at burning calories as an indoor racing bike and the S4K is an incredibly well priced highly specked unit that offers all of the features you will find on your gyms bikes but at a fraction of the price.
