    Kurt road machine v spin bike advice

    For the last few years I've been using a Kurt road machine for winter training, keeping an old small frame hybrid bike on it as my wife uses it occasionally and is a foot shorter than me. We'll be moving soon and seriously downsizing so I'm considering switching to a dedicated spin bike that will be adjustable enough for us both to use and also take up a bit less floor space. It'll be used lots (long Canadian winters) so I'm willing to put out the cash for a good one. I'd be interested in hearing from anyone who's gone this route mostly about the "feel" of a spin bike v the road machine. Should also say I've been very happy with the road machine but the spin bike would suit our new situation better.
    Thanks.

    Ever been to a spin class? It's different from cycling, despite appearances.
    It's good exercise that will help a lot come Spring, but it's still different.


    1) You have a KK, use it. It'll save bucks, and the difference in floor space is small.
    In fact, you would still have your regular bike and you would be adding another bike,
    wouldn't it take up even more space?

    2) Neither of the above, take spin classes.
    We are as gods, we might as well get good at it.

    I use a spin bike in the winter. The do intervals and usually ride for 45-60 minutes which gets me into a good sweat and my heart into the 140's. The big difference is there are no hills and no wind. I've never used a KK but would imagine they are similar.

    The thing is that a spin bike has a belt drive to a heavy flywheel and no freewheel. That results in a very different exercise and application of force around the pedal circle from a road bike on a trainer. It's not the same thing, not at all. The other thing is that nothing fits you like your road bike and it's important to train with the same fit and hand positions as your road bike. It's easy to clip your bike or your wife's into a trainer, unless you're figuring on taking away your wife's bike, not recommended. The best thing is to have two trainers, facing each other, so you can both ride at the same time. You'd need two box fans, too. I have a set of rollers for me, while my wife prefers a trainer, so that's what we do. I wouldn't train as often on my rollers if my wife weren't there and vice versa for sure.

    That said, we both go to the gym about once a week in the winter for a spin class, for the social aspect and to do something different. Takes a little of the sameness out of it.

    Thanks for the replies guys. I do have rollers too so can use those with one of my road bikes.

    I have posed the same question. I am considering one of the KK trainers but also considering the Sole 700 spin bike.

    We took spin classes and loved the cardio aspect. It's also 3 minutes away but for $12 / session per person, I'd sooner invest $600-$800 in good home equipment that we can use. I am still on the fence as both options have their merits.

    I like a good spin bike; very solid, sturdy, and quiet. Agree that the fixie aspect is different than the a freewheel road bike. The resistance curve is different too. With most spin bikes, the resistance is constant with RPM so power is proportional to cadence. With most trainers, resistance increases with rpm so power goes as the square or some higher power of cadence. The former is sorta like climbing where power is proportion to speed and the latter is sorta like riding on the flats where power is proportional to the cube of speed. Personally, I've found that the spin bike and cadence drill thereon have improved my pedaling souplesse.
    Ride more. Fret less.

    I do at least half of my biking on a spinner bike. It isn't the same as a real bike, but is surprisingly close. I would able to get the setup of my Lemond Revmaster pretty close to my road bike.

    You really notice that resistance is not a function of RPM (unlike being on the road). OTOH, I can simulate a 20 minute climb on my spinner that is impossible to do in the area where I do my training (lots of ups and downs but nothing very long). I've never been on a real trainer, so can't comment about the comparison. But I find my spinner to be a nice augment to my training.

    I've been looking at the CycleOps Pro series, they have freewheels so the feel is supposed to be more like a real bike, lots of adjustment too for different sized riders. Not cheap but what is these days.
