Dripex exercise bike.  Fully assembled.  Bought new in August 2021 for £300.  I used it for about a year and then stopped, as I switched to going to the gym.

I am not sure of the model number.  The manual says "HP-SP0909" and "RW210106" on the front.

It is a really solid machine and in excellent condition.  It was selected by a personal trainer friend, who I asked to choose me a good one.

Turning the knob increases or decreases resistance.  The computer does little in terms of programmes; if you want that you would have to find something separately on e.g. YouTube.

I enjoyed using it.
