DKN RB 4i Design
Setup
This is a 50 kg exercise bike, so there’s some issue with its installation. It isn’t exactly difficult to put together, but it may take more than 30 minutes to do it yourself.
Most of the parts are heavy, so even getting everything out of the box will be a struggle. This means you need to call someone to help get the task done.
We recommend installing the heavy bike in its permanent spot so that you don’t have to move it around afterward.
Comfort
The DKN RB 4i recumbent exercise bike comfortably supports your lower back since it is a recumbent exercise bike. Its best feature is probably the padded seat with support on the back and armrests. Essentially, this prevents lower back problems, which a 2010 study found to occur in 45% of professional cyclists.
In addition, the bike’s seat comes with a wide variety of adjustments to cater to different heights and offer the most comfortable riding position possible.
For added riding stability, the bike has two adjustable toe cages that keep your feet secure as you ride.
