Please don't hesitate to buy this machine . I use a recumbent bike at the gym on doctors orders , I broke my hip 10 months ago and it is only just healing . I find this machine as useful as the gym one if not better . I have a comfortable sofa and a television in front of me , I don't even know I am exercising . It is sturdy and straightforward to assemble makes No noise and was packed well !!! . It doesn't move on my carpet which I was worried about , I ordered a mat too but I don't need it , I've been away to get undressed and digital counters have returned with a small rotation of the pedals so I can carry on where I left off ! I really love it , burnt lots of calories already , my granddaughter age 11 has had a go and thinks its cool . I had the last black one as I think it "mingles " in with the furniture , there are colours left but maybe more black ones will come in , its worth asking . I have only had it since 11 o'clock this morning , it's now 9 at night and I am thrilled with it . Will be pedalling away in the morning while I'm eating my breakfast , I want to loose weight for the summer months . Hope this helps anyone who is not sure , yours Susan .
