The construction of the ergometer is easy, it also needs no "third" hand. The display is very clear to read and beautifully clear, operation simple. I as a person totally unsportsmanlike train already several weeks like this unit of AsVIVA (to slim down). I also think that one z. B. can change the setting of each level without having to stop. Wenns halt is sometimes too heavy or too light. I have the acquisition of Cardio III not regretted a second. The lockable height of the saddle (have retrofitted with saddlecloth) the floor is approximately 85 cm, for short legs which is too high, I just had luck. Whether this information could be included in the information about the product -also other manufacturer?
