Decided to get one of these things in an effort to get fit on dark winter nights when a trip out doesn't exactly seem attractive. I figured for the cost of about two months gym membership it stacked up as pretty good value.
I'm pretty happy with my trainer in operation. Once you have it set up and adjusted properly it provides a nice stable ride and its really easy to fit and remove your bike from it with just two levers. It makes a bit of a whirring noise but nothing of note. The trick is to get the tilt on the roller right by trial and error. Once you find the sweet spot you never have to worry about it again. Whole thing folds down pretty neatly for stowing away when not in use.
I did find it quite a fiddle to assemble though. You have a certain amount of building to do and the instructions are not very clear. Indeed I have a number of bolts, nuts and washers left over which I remain none-the wiser about. Also, despite the claim that the handlebar controller fits most bikes, it doesn't fit mine - a pretty standard Specialised hybrid so I was surprised.
It looks like the Swing model is pretty much the same as the Sirius. I suspect its just a marketing thing and they've renamed it. Here's hoping the instructions are clearer on the Swing.
All in all a good purchase though. More expensive models tell you work rates and how far you have gone. I didn't figure I needed that. Cheaper models don't have adjustable resistance which I think is essential for any meaningful training regime.
Unforseen benefit is that the trainer also doubles as a great stand for when you want to work on the bike - adjust gears, brakes etc.Allows you to hold the bike steady while turning pedals and wheels and so aids maintenance. A bonus.
