Any advice for total beginners going for general fitness / weight loss?

Simple advice:

Don't injure yourself

This is the most important one.

You can hurt yourself several ways, but the easiest by far is pushing on when your body is telling you to stop. If you're in pain - and it's not just the pain of tired legs - then something is wrong and there will probably be a way to fix it (google/ask here for advice).

Don't bite off more than you can chew

Don't start up on a training load that is unsustainable. Not only are you more likely to injure yourself, but you'll also burn out mentally. Just chill out to start with and build up gradually.

...but challenge yourself a couple of times a week

Whether that's going for a longer one or some hard intervals depends entirely on what you find fun. A good session to do to challenge yourself initially is a ramp test (which you'll find under FTP tests in Zwift), which will give you a power reading to calibrate other sessions around. It'll also be a measurable thing to track your progress - weight loss is the kind of thing it's best to let happen passively (it's affected by loads of things, including the weather, hormones, etc), but measuring your FTP gives you a simple thing to look at and go "hell yeah I'm getting fitter and stronger". A lot of people also enjoy Zwift racing, but that's something to think about further down the line.

Going back a ways to using a spin bike as cross training rather than a turbo as cycling training, but I found that for the same low-medium intensity session a fan made a difference of 20bpm to my HR.

Important part, as I'm sure you're aware, is to respect what your body is currently capable of. It's a much better feeling to be conservative and then destroy every target than to push out too hard and never finish a workout.

Back before I was cycling regularly I was using an M3i to cross train down at the rowing club, and it worked.

One thing I found was that the resistance lever could slip a bit, resulting in the workout getting slightly easier over time; this may have been a consequence of many years of heavy use. However, it didn't slip much.

And like any piece of home gym equipment, the biggest ‘is it worth it’ comes down to whether you use it consistently and if you are happy with it. If the bike and app environment does it for you and keeps you interested/motivated and isn’t causing you to have to skip rent, then it was a good purchase imo.

Yep. Obsessing over the best purchase isn't going to do anything other than stress you out. Good enough is good enough

I picked up a kickr core and it’s not the same height as my back wheel, resulting in my seat angle being goofed up when the bike is on the trainer. Is there a fix for this?

Too high or too low? If it's too high, a block under the front wheel is what you need. (This is a standard problem with trainers)

It depends on what's on the Felt FR60 - I googled one and it appears to have Shimano Claris, is that correct?

Ideally what you want to do is to put a cassette on there that's the same speed as your groupset, which in this case is 8. While that's not officially supported (afaik), there's plenty of reports of putting an 8 speed cassette on it with sufficient spacers and it working fine. If you're not confident with doing this, it's a quick job for someone with the right tools. Likewise if it's 9/10 speed (although those ARE officially supported)

Bear in mind that it's just a mathematical fact that you're going to see a much larger proportion of riders who are going faster than you than the ones going a similar speed. This is doubly true on climbs as the speed differential is much higher.

MrL_JaKiri
Sep 23, 2003

A bracing glass of carrot juice!
In case anyone is interested, to go into the maths of it a bit:

Let's say you're going up a climb that takes you an hour, and there's a constant stream of other riders starting the climb with varying speeds.

Consider someone going very slightly faster than you - say, they do it in 59 minutes. If they start a moment behind you then they'll overtake you. If they start a minute behind you they'll overtake you at the summit. If they start more than that behind you, then you'll never see them. So in that hour, you see 1/60th of the hourly rate of those riders.

Now consider someone going a lot faster than you - say, they do it in 30 minutes. Now, they'll overtake you if they start anything up to half an hour after you instead of just a minute. This means that you see a full 50% of the riders who start that hour who go at that speed, 30 times the proportion of the riders at a similar speed.

Something similar is true for riders who are slower than you as well. If someone takes, say, 1h20 to go up the climb then you'll catch all the riders who started at most 20 minutes before you, meaning you see 1/3rd of an hour's worth of those riders as you go up.

In general, the proportion you'll see of a given pace is related to | tyours - ttheirs |. What does this look like?

Let's assume that rider speed is normally distributed, like so:



If you're a lot faster than average (a full SD away, so faster than 84% of people), most people you see will be substantially slower than the average.



If you're a little slower than average (faster than about a third of people), you'll think the most typical speed is nearly as fast as the fast rider above!



And if you're bog standard average you'll see that most people are either a lot faster than you or a lot slower than you, despite there actually being more than 2/3 of riders between those peaks.

I did my first big group Zwift event tonight and I need to get better at positioning. I felt like I was constantly going forwards or backwards in the pack.

There's a lot more surging in Zwift groups, even in races, because the draft is a lot weaker than in real life.

What exactly do you want it for?

The Kickr Bike is incredibly expensive, and while it does include extra features over the Wattbike Atom or Tacx Bike to kinda justify it, stuff like the gradient change feature aren't really worth an extra grand or so in my opinion. Getting a second bike and a trainer is only worthwhile if that bike's going to be ridden outside, imo, especially given how difficult it is to get bikes at the moment.

In any case, the price difference between a bike + a kickr vs a wattbike atom isn't going to be enormous, and you don't have to deal with any of the additional troubleshooting that comes with the increased mechanical complexity.

There's also the option of a wheel-on trainer which will be much quicker to change for your commuter and also much cheaper, but it's a load cheaper for a reason.

A wheel on trainer will always point "downwards" because the wheel needs to be raised off the ground. You don't necessarily need a specialist block - I used to use a book that was the right size.

I would seriously not be concerned about the possibility of any new versions. I have a Kickr and most of the time for my usage it functions very similarly to the Tacx Bluematic turbo I bought a decade ago for around 1/10th the price.

or to convince me that's a dumb idea since I already own a bike and could just get a trainer.

If you just want to sit there and do some exercise without worrying about Zwift or anything but increasing your heart rate, cheap wheel on trainers can be had for $100 or less. Maybe you'll want to invest in a trainer tyre, but again that's not a great outlay. No need to spend money if you're on a budget and you don't have to.

As you have a road bike already I'd suggest a turbo trainer, but as you go between the trainer and the road a lot then a stationary bike sounds like it fits your use case better.

There's a few different options of "high quality stationary bike" to choose from, here's some reviews:

https://www.dcrainmaker.com/2020/07/stages-bike-sb20-smart-bike-in-depth-review.html
https://www.dcrainmaker.com/2019/12/wahoo-kickr-bike-in-depth-review.html
https://www.dcrainmaker.com/2020/10/wattbike-smart-review.html

All the ones I've linked are super high quality, and given that the differences between them is pretty small then if it's within budget just choose whatever.

There are cheaper alternatives (eg can you replace the pedals on the spin bike with some power pedals? That'll let you zwift, albeit without erg mode) but it's a trade off between price and convenience/functionality. Convenience is especially important - the more work I have to do to actually start a workout the less motivation I have to actually get the workout done properly

It's the original Tacx Neo from 2015, but it's not like turbo technology has moved on hugely. One caveat emptor thing here is that Garmin does not like people repairing its products, so if it's duff and given you don't have warranty you've just bought a big paperweight.
