The build of the Tacx is second to none, and the interface between bike and trainer (cups and quick release) is excellent, without any leaning to one side or slop at the rear axle. The resistance on this unit is higher than my old Cycletrack magnetic trainer. Some spring is designed into the frame, so that it feels like the wheel is on the ground rather than being fixed at the axle, which is great. The higher mass 2kg flywheel in combination with the 3cm diameter of the roller means the inertia in the flywheel provides a realistic road feeling for me. In setting 2, 39/14 it feels like riding on the road and the wheel spins easily through my pedalling dead spots. The quick release handle bringing the roller up to the tyre is great for getting consistent rolling resistance between training sessions and looks more durable than other well known brands.

There is nearly no resistance on setting 1, just resistance from the tyre, setting 2 is like easy road riding, on setting 3, training in 39/15 at 100rpm will get my HR up to 160/165bpm, 4 and onwards are like climbing and provide eye popping resistance levels: I think anything beyond 4 requires a turbo specific tyre as I have blown up an inner tube riding on the higher settings already since the beginning of Jan 2011. A fan is absolutely essential, as is some music and an open garage door. Training indoors on this will mean your HR readings are off due to overheating, and you will also get oil falling off from the chain.

Whats nice about a turbo is that when the weather is terrible, you can still get a decent training session in. To do this regularly though, you need a turbo which is not going to annoy you, or bore you. It needs to provide a firm base for holding the bike, variable resistance, and realistic inertia.

4.0 out of 5 stars biking in your living room 10 Feb 2008
By doublegone TOP 500 REVIEWER
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.

5.0 out of 5 stars really great product 24 Jan 2013
Verified Purchase
can work up a real sweat with this... But more importantly Amazon should pay full UK taxes. It benefits from operating in the UK, yet puts virtually zero back-not good enough Amazon! Contribute to our society and welfare system! Apart from anything else it means that they compete unfairly with great British companies like John Lewis, who pay full UK taxes. Come on Amazon-cough up!
