    Bk4 Excellent bike

    Posted by julien on 25th Oct 2021

    Excellent bike for the price. Really sturdy, strong resistance and fairly quiet. Buying a bike online I was concerned that it wouldn't be high enough as I'm 198cm - if it helps anyone looking, I have one or two points in the seat post remaining and the handle bar design means that you will always clear your knees. Also 5* for the staff at fitonline. The bike was delivered missing a part (it happens) and they arranged the part to be sent the same day from a supplier in Australia.

    Great bike.easy to build. Seat is comfortable but your body needs to get used to it like any exercise bike.

    Works as expected

    Posted by Andrew on 14th Sep 2021

    Only had the bike for a few weeks. Thoughts are: Bike was easy to put together however the instructions are not written by a native English speaker and the instructions and diagram for one specific section was ambiguous. Bike functions without issue and I have no height issues (6’0”) and am no where near the tallest it can go Bike is very stable and is easy to move around on its wheels even though it’s quite heavy. It’s an expensive price but so far the quality of the bike has justified the price.

    Sturdy, stable and quiet, this bike has surprised and delighted me. The seat is really comfortable and simple to adjust. I'm glad I spent the extra money.
