How many full pedal rotations per kilometer on a stationary bike?

I doubt so, every stationary bike manufacturer can make it differently. But it would not make that much sense for comparison anyway. Every kilometer takes a different effort based on the slope, ...

How many full pedal rotations per kilometer on a stationary bike?

No. The main problem is the "resistance" setting which could range from zero/none right up to high/hard, (or Bart Simpson riding at night with a bottle dynamo on) I presume you're looking ...

Are X-shaped stationary bikes any good?

Presumably you already have a bike. It may be better to look at a set of rollers (which fold up), or a trainer that replaces your bike's rear wheel. Both options require you to use your bike, so ...

How many full pedal rotations per kilometer on a stationary bike?

What matters is your power output. On a real bike speed by itself is relatively meaningless. You can do a slow 15km/h but still be outputting 200W because there is a headwind or because it’s a 7% ...

Why would I choose a bike trainer over a stationary bike?

The main difference is cost, both money and space. If you already own a bicycle then it is using up space whether you can ride it or not. If you want to use the existing bike on a trainer then that ...

Replacing non-standard pedals on an exercise bike

9/16"x20tpi is the predominant modern size, and 1/2" also exists. On bicycles, 1/2"x20tpi is virtually always only found on one-piece cranks, but exercise bikes can do whatever. They ...

What power adapter to use for the Cybex 700 stationary bike?

Most information appears to have vanished from the official website, but other specifications suggest it's just a 12V power plug. I've tested a universal power supply and 12 V, 1 A turned out to work ...

Why would I choose a bike trainer over a stationary bike?

We perspire. This is obvious. However, when cycling outdoors, moving air cools you considerably. Indoors, even with fans, you do drip sweat on your bike. In extreme cases, this can cause corrosion. ...

Are X-shaped stationary bikes any good?

The position is more suited to exercises like spinning, that are meant to also train the upper body. If your goal is to train for cycling, a bike trainer seems to be more appropriate, although the ...

Can an odometer (magnet) be attached to an exercise bicycle crank arm (not the pedal)?

For your requirements this would work fine. The speedo readout would not reflect a real-world value, but for comparing efforts on the same bike it would be ideal. I'd suggest the lowest priced wired ...

Can an odometer (magnet) be attached to an exercise bicycle crank arm (not the pedal)?

Putting the sensor on the crank would work in principle. In terms of if it would mean anything in the real world, you'd first have to ask what has real world meaning on an exercise bike, anyway? Even ...

Loose crank exercise bike

You need to figure out what's wobbling. The pictures I find suggest that it has a three-piece crank, so you can get wobble from three sources: The pedals are wobbling where they screw into the crank ...

How to add resistance to my bike trainer?

I have a CycleOps fluid 2, and I'm assuming yours works similarly since they are both fluid trainers. Fluid trainers don't have adjustable resistance. If you want the resistance to be harder, shift ...

Why would I choose a bike trainer over a stationary bike?

The cheaper stationary bikes sold for home use tend to be "one size fits none". The better ones, with a wide range of adjustment for several parameters, are expensive. You might be lucky. I ...

Anyone heard of the ZCycle ZBike? How would it (or any stationary bike) compare to a Kickr Core setup?

The question as written is a bit opinion based. We can say that smart bikes and trainers are not easy to make well. There may be a few issues even with higher end ones. For example, the Wattbike Atom ...

What power adapter to use for the Cybex 700 stationary bike?

For a R700 Cybex bike the power supply needs to be 12V 1A (higher is ok), and the plug is referred to as a TIP-C or generically the exact specifications are 2.5mm x 5.5mm barrell plug.
