Top 5 Indoor Cycling Fans for your Pain Cave

| | ,

You might have the best smart trainer. But without a decent indoor cycling fan, you will find yourself working a lot (and I mean a lot) harder. 

Riding Watopia at 30mph on Zwift requires the same amount of cooling as you would get outdoors.

This is because sweat is your body’s way of removing heat from your body. On the road, it evaporates as the air flows around you.

Indoors it stays where it is. On you.  And as the sweat (ie the heat) stays on your body, so you sweat more. And then the blood is thickened by the loss of fluid. 

This forces the heart to pump harder. And you get into a cycle (no pun intended).

This is how you get cardiac drift.

But think again if you’re considering grabbing that fan from the kitchen or the kids’ bedroom. You need a one that is more suitable for the kind of heat generated by indoor cycling and Zwift. 

That’s what we’re going to look at here.

What happens without a turbo trainer fan

Your body is a heat making machine.

By sweating we can keep riding without stopping to remove heat.

Only horses have the same advantage. Everything else has to pant.

Without going too heavily into the science, when you’re pedalling on Zwift you are producing up to 3x more watts as heat than watts on the bike. 

If this heat is not removed you end up creating more and more heat. This will affect your body’s ability to maintain that output. 

What ventilation you get outdoors

This one depends on the weather, but even on a still day, you can move considerable airflow around your bike. 

Fans are measured in Cubic Feet per Minute. This is just a way of measuring how much air a fan can move in a minute (there’s more on this further down). 

The more air the better. 

Now, this is a rough estimate, but if you’re riding between 25-33 km/h, your upper body alone will be hit by between 7,000 to 8,000 CFM.

How to Choose an Indoor Cycling Fan

There are three things to consider when buying a turbo trainer fan. 

  • Cubic feet per minute (CFM) – the measurement of how much air the fan can project in a minute.
  • Range of circulation – ow far the air will travel. Useful, if you are in a big room. Not so important for indoor cycling.
  • Directional Fans – avoid oscillating fans. This is a fan’s ability to move backwards and forwards and cover the room. But we don’t want to cover the room. You want it to cover us (apologies if that sounds a bit weird).

We something for a hot workshop or mechanical garage – not the house.

What fan will keep you cool and performing well – go Directional

There are a lot of fans you can go for, whether you’re in the office or cooling the kids’ bedroom at night. 

Oscillating, drum fans, pedestal, etc. 

We are not interested in any of these. For our purposes, we will go for a floor-based directional fan with a high CFM that can project air in your direction. 

For indoor cycling, speed tops the amount of air. Remember, we’re cycling on the spot so a directed airflow is what you need. 

Last point – the best Indoor Cycling Fan set up

This really requires a separate post. But the simple answer, unless it has a high CFM, is you ideally need to use two directional fans. 

One for each side of you. 

It’s a common mistake to direct a fan at your front – because that’s the way you’re riding. But there’s always going to be more airflow that way. 

Directing fans on either side from the floor up will ensure close to 100% coverage. 

Simply position the fans 2 metres away and direct the airflow towards your chest. That way you core and head will get the bulk of the cool air. 

One last tip, look at getting a remote to switch them on. When you start riding the last thing you need is icy air blasted over you, especially when you are cold anyway.

So next, let’s get beyond the hot air and look at the different fans I’ve tried or owned and look at their pros and cons.

Honeywell HT908 indoor cycling fan

Best Fan if you just want to get the job done

Honeywell HT-900 Turbo Force Room Air Circulator, Black

If you are looking for a dependable floor standing fan then the Honeywell HT-900 fits the bill. It’s both affordable, portable, and capable of directing air onto your overheating torso.

In terms of the specifications, it has a cubic feet per minute rating of around 230. It works on three-speeds – although you will usually have on maximum. 

Oh, and I actually own two of these. 

Pros

If you’re looking for something small and basic, then this will do the job and keep you cool on a hot day. Be aware though, you will need to have it on full blast.  

Cons

This is a manually operated fan. If it is located on the ground then you will need to switch it on before you get on the bike. Personally, I hate that feeling of cold air blasted on you when you were cold to begin with. There are remote control options, but you will need to buy that separately. Last, you need two of these.

Best Premium Bike Trainer Fan Option

Wahoo Kickr Headwind

Ok, I have a confession to make. I have a mate who owns one of these and I would really love one too. 

To be honest, it’s more than just a fan. It’s an extravagance. 

The Kickr Headwind ties up with your trainer and whatever application you’re using. Simply put, it’s interactive and blows more air at you the faster you go. It can also be tied to your heart rate.

Having tried it, it adds another dimension to your indoor cycling. Does it replace the actual wind? No, but I don’t think it tries to.

And there’s also a steady (ordinary) fan mode too. 

Pro 

Ok, it blows air. But this is also a different product to the other options here. It does more than keep you cool, it simulates riding outdoors. 

It’s so powerful you don’t need to have one either side. If you are building a deluxe pain palace then this is a must – that and a Kickr Climb.

Con

Ok, it blows air (see what I did there). But curiously, Wahoo don’t say how much. In fact if you look elsewhere, you won’t find the number. Well, I’ve felt it and it does blow. The question is, how much do you want that extra bit of reality?

Lasko-indoor-cycling-fan-1 Top 5 Indoor Cycling Fans for your Pain Cave
Lasko High Velocity Fan

Best Trainer Fan with Remote Control

Lasko 20″ High Velocity Fan with Remote Control, Black

If you’ve read all the way down, you’ll know my thoughts on starting cold with a fan blowing on you. So if you’re looking for a quality fan – that’s not too expensive – you could do a lot worse than the Lasko. 

The remote control allows you to do what the Honeywell cannot – blow cool air when you need it. 

It also has a 20-inch diameter blade and – importantly, a high CFM. That is pretty good for the price, which is why they tend to sell out.

Pro 

It’s floor-mounted. Has a decent CFM and is remote controlled. 

Con

However, it is loud. That might not matter if you are using a high decibel trainer. The Lasko blows out a lot of air but in my experience, it is slightly less directional than some of the fans here. So more air will be wasted around the room rather on you cycling.

Vornado 293 indoor cycling fan

Most portable directional fan with power

Vornado 293 Large Heavy Duty Air Circulator

The Vornado is about the velocity of the air it pushes out (see above). It can push air out to over 100 feet away and has a CFM of 750. It is actually designed for the shop floor and garages, which is fine for a cycling pain cave. 

Also, the high velocity of the makes it ideal for replicating your movement along the road. Something to consider if you like the idea of the Wahoo Kickr Headwind. 

Pro 

Its high air velocity means you really feel the air hitting you – so it will keep you cool on the hottest of days. No matter how hard you are racing on Zwift. 

Cons

No remote control.

Highest CFM Fan

MaxxAir 24-Inch 2-in-1 High Velocity Air Movement Portable Air Circulator

Sometimes you just want to go big. If you’re in a naturally environment and some air flowing through the space. No fuss. No messing around with fans positioned either side of the bike. 

This is a drum fan with around 7,000 CFM at top whack. 4,000 CFM at the low speed setting. For the price, it’s decent value for money and quite portable too. 

This will do the job for you. It tends to be used in car repair garages etc, where heat comes from engines etc.

Moreover, you will not need two of these. In fact, I would think twice about this if you have a small pain cave. It will literally blow you away.

Pro

It blows out a lot of air and is capable of standing close to chest height when on the bike. You’ll only need one of these.

Con

No remote control, fairly big, quite noisy.
