The Viavito ' Satori ' computer console sent with the original purchase from ' Sweatband ' ( Ebay UK ) - which seems to be just an E-Bay outlet for Viavito.com - had problems from day one . Problems with their computer consoles have often been reported . They quickly sent out a replacement console , which had different problems from the first . I had tried their suggestions for checking the electrical connections . and the power off and back on - but I had the screen freezing , with no other way to escape but press and hold ' Reset ' , and found that the usual settings for weight , gender , age and height would not always register . There are problems with the console - which they don't seem to have fixed ; they have now offered me a second replacement console , and don't even ask for the previous ones to be returned ; perhaps they can't be fixed . I had specific problems the computer would not do a' Recovery ' assessment at the end of a workout - but would only do so somewhere before the end of it , meaning you have to stop for 60 seconds before you've finished a workout , and even then , after it had given a Recovery estimate , the console froze when I pressed the ' recovery ' button again to continue with the program ; the only escape was to do a complete reset . The custom ' User ' function would not begin after pressing ' Start ' - which it had done , using the original console . Customer services , if originally very helpful , promised to to call me back with a technical expert to answer my questions , but didn't . When I phoned them again , they just hung up the phone ! Their ' good - will ' offering now , of a second , free replacement console , would see to hide computer problems they have still not fixed . For most functions , most of the time , the bike works , but there were these unresolved issues they refused to discuss - and the cost of sending the whole bike back , should they choose to say 'everything working OK ' , would have been £50 in postage , there and back - so I didn't risk a return under warranty , given they have already avoided my customer enquiries . I also felt there was a new problem with the mechanical mechanism engaging the resistance . With the first console it would make no noise until a load setting had been entered , and the timer ' Start ' button pressed , but only for a few seconds . With the second console , it took 10 -12 seconds before the resistance would be engaged - the timer would be counting down , but you were pedalling thin air for the first 10 - 12 seconds of the workout ; if I went to a shop and this happened , I would just walk away , but in their opinion is that this is ' normal ' for this model . An awful lot to like about the bike if it is working properly , but quite a let down , followed by evasive customer services - in my opinion .
