Hey Shane, I like the addition of your “ride feel” chat straight after you jumped off the bike from the 1st ride. Please do this more when doing other reviews, it adds an interesting dimension to the review. Brilliant as always 👍🏻

Another excellent review Shane. Production is super slick these days too, 5 stars mate. Still really like the frank information/comments without unnecessary drama.

Got mine last week, so far so good (I'm using it with 1x10 mtb as long as I can buy a proper Road bike) - Heavier than my previous Tax Flow but smaller: Happy days - A lot silent than previous: Happy days - Mine came with adapters for different tru axles: Happy days - No issues with calibrating or upgrading firmware: Happy days Came with 1mm cassette spacer but instead used a 2mm to fit ten speed cassette and as you said, it handles well long cage rear derailleur. Cheers

thanks shane. i have been waiting long for this video from you!

The reviews come thick and fast. You are really ON IT with the content these days :) Love it. Great review once again. Tidy Lama lab DOES make a big difference by the way. :) Also, whenever you get on it and break into a 1000+ watt sprint, I'm always a bit worried, that you're going to break something. Haha. As for the Flux S and its limitations, I'm really thinking about getting into the direct drive trainer game but I have trouble deciding on what to get. Mid range aka Flux S or go for the higher end stuff (Core, Direto, Flux 2). Any chance you could do a head to head between those three at one point between those three? It would be interesting to get your take on it. Maybe it will help with the decision on what to get. :) Thanks. And as always keep up the awesome work. You've really stepped up your KZfaq game over the past few months and it's really showing.

thanks to you and dcrainmakers review i purchased a elite direto just over a month ago, i notice occasion quirkyness that i have adapted to. as a fitness tool i love it. mind you i had no roadbike and didnt want to use my mtb on it full time so my local bike shop let me know of a well taken care of old road bike. granted its a 1990 trek 1420 it does very well i was worried it wouldnt fit as it was a 7 speed but it works great the oddity in zwift i had to adjust to was in sim mode passing people up hill and getting passed going downhill. being a clydesdale both of those are opposite what happens on the road. your content is valuable for people and is greatly appreciated. living in northern maine US where winter has already set in(30+ inches of snow on the ground already) having the bike and positive social interactions on zwift are great and keep me moving forward. out on the roads most skinney cyclists look down on seeing my fat self passing them :P in game we all look skinny

High five! What would I do without Shane‼️

Thanks Shane. Another great review! As a software guy, I laughed out loud at the text placeholder. Lol

5:22 in I gave you a Ride on!!!!!!!! This made my Friday!!!

I just got this trainer and had the same calibration issue too last night. I just thought it was just me and was doing something wrong.. Total newbie to smart trainers. Love your channel and work.

I experience those same 'jumping numbers' in ERG mode on the Neo 2. Made me worried in the beginning, but indeed averaged out these are spot on.

...the price is quite expensive. i'm not sure if my wife is gonna be as quiet as this tacx smart trainer if I buy it...

Nice info Shane, thanks :)

Have had 2 rides on this now and really struggling with ERG mode, power seems off and its killing me to complete a trainerroad workout. I've also had to change gears to get it right, I tried resistance mode then and it seemed much better. Is it possible there's something wrong?

Looks good. I can still see why I would buy a Neo over a Flux. One reason being serviceability. The Neo can be fully taken apart and serviced and parts replaced. I've not seen that with the Flux.

Would you buy a Flux s or a waho kickr core? I had a Flux 1 but he broke after. 200kms of use..

Hello Shane and everyone! I was wondering do I need to buy a front wheel raiser? Or is it not needed ? Nothing comes in the box so I guessed it was not needed. Will I do damage on my bike? Or is it just a more pleasant experience having a front wheel raiser? Thank you!

I have a TACX Vortex. I've not been able to calibrate the trainer lately. Decided to uninstall the App on my Samsung S7 and reinstall. Logged in and was able to calibrate. Hope this helps.

Hi there, I just got my Flux S, and it's class. However when was performing a ramp test on Erg Mode, the trainer got to about 360W and then did not continue to ramp up....I kept the cadence at 95Rpm or thereabouts. Is there anything I could be doing wrong? I know this is rated to 1500W. Cheers Jake

Someone please help; I’ve installed this but for some reason the cassette (11 speed Shimano 105) is wobbly. Everything seems correct and tight but I can’t figure out where or how to tighten it up??

Looks nice and smooth.

Can you do a follow up on these, have they sorted their issues?

Will this pair with my Fenix 5? Will I need to but any other sensors to get all my data to my F5?

Nice to see some direct drive competition in that 750 or so range. Now it just needs to drop another 250 or so! 😀

Cripes Shane I thought it was back.to the future for a moment there..flux...flux.. I was hoping for a vacuum.review :-)

Hi Shane! Been hooked on your channel for the last few weeks, so thanks for the great content. I was wondering if you could help me: do you think a brand new Flux S for 450eur is a worthy deal? Just for some background: I abandoned hardcore cycling a couple of years ago as I was quite devoted to it and it took up way too much of what little free time I had from work. So I took up other sports like CrossFit, gymnastics, running, etc. But I really miss the cardio fitness and the zen feeling when you hit the spot on a ride and just stay there, mindlessly suffering away! Recently the Crossfit gym where I workout got a Concept2 bike erg, I connected it to zwift and my addiction came flooding back. I can never go back to spending 5 hours+ on a bike ride away from home, but zwift really has become a wonderful way to kill my addiction and be home at the same time. Do I get the flux s, or do you think I should just take advantage of the bike erg at the gym, as I’ve done? A video on the concept2 bike erg and zwift would be awesome!! Thanks again and forgive the long message!

Newbie question but how do you know what kit you need to purchase with this? What cassettes ,tool, bolts etc you would need to buy if you started with nothing

Hi everyone, i have ordered a tacx vortex for 250, and now realising by the time i buy myself a trainer wheel/tyre/tube/cassette ant+ etc i wont be far off the price of a FLUX S. Anyway i only have an 8 gear rear cassette on my btwin bike for now, can i fit those on this? or does it not matter? a reply would be very appreciated from anyone as i have no idea

any updates on this trainer ?? planning to buy from a friend and he's worried id be to powerful for it and it'll break on me ? i do ride a relatively high level. thoughts ??

Witch one should I choose between the Elite Zumo and the Flux S

All these trainer and equipment manufactures seem to fail on the QC of new releases. Just seems their just not fussy and thorough enough. Learnt my lesson with the KCKR 18 issues as an updated model and went with the time tested Neo 1.

Next is a review of the dyson?

If a Tacx can report cadence from the unit, I wonder why Wahoos cannot. Not an issue for me, as I use Assioma pedals, but curious.

which trainer do you use and recommend

I wanted to get the FLUX S on black friday...alas no. My Taxc Flow Smart does the same calibrating sometimes...Usually when the trainer has already connected to the PC via Ant+ and the calibration uses BlueTooth. I have to unplug the ant+ dongle from PC then turn trainer off and on again, it will then connect to my Android with out problem.

Why put the power cable so it hangs in the air ready to be tripped over!?

Thanks Shane for a great review. Any issue with disk brake caliper clearance to the unit on the non drive side ? I am looking at direct drive trainers to use with my old Boardman CX Bike with mechanical disk brakes. Standard 135mm rear fork width.

Good pronunciation !! Flux this flux that Flux MS max!!

I figure the less resistance the trainer has to deliver, the less power it consumes, so I always pick the gear just below the one where I outride it. I know that's not really the point of erg mode, but I think it's the greenest option ;-)

I can't believe these are still being manufactured. I got rid of mine 2 years ago after 2 failures. Just look at the Tacx flux owners FB page. Even the S model which is fundamentally the same design is having problems with noise etc. You'll get fitter watching t.v than if you buy one of these.

I am sure you have already answered this before but I cannot find right keywords. Do we need to calibrate Flux before each training session? I mean after plugin power cable. Or it saves initial calibration settings. Thanks

I’m waiting for mine to be delivered any day soon 😁 Hurry the f up GLS

i've been using a Tacx Satori until now because I mainly use it for short enduro intervals so I've been using the resistance lever to quickly switch it around. How do you do that with fully smart trainers? (they don't have any levers I think?)

Hi Shane! Tacx Flux S, Elite Direto or Wahoo Kickr Core? Which is the best choise?

Hey Shane, I realize this video is 1 year old. However, I need advice.. The options I have are 1. A used Tracx Neo 1 (2018 model used for ~2K KM), and option 2. a new flux S (2020) model... Which one would you go for? both are almost at the same price.

Hey Shane. Any update on accuracy after calibration???? Have you used a flux 2 yet? If so what do you think?

Shane, i'm trying to decide between Flux S and 2, did you know if thru axel compatibility is "native" in Flux 2? also, any chance tacx have fixed the known problem with ERG Mode ? great channel, always very imformative, i would love to hear you in a trainerRoad podcast :p

Morning, firstly I love your videos bud :) wondering if I could ask some advice. I am newish to cycling but have got the bug big time. I am looking to purchase a trainer though haven't got much support in some shops and online can be a mine field off information I don't really understand :( I am looking to use Swift as with winter in the UK, I have only been averaging 50 miles per week. Ideally I would like the trainer to respond to hills etc app controlled resistance. Cant decide which one is best. My current bike is a boardman SLR though it only has 8 on the back cassette. Would this work with the Neo Smart S? the other trainers that seem popular are the Wahoo Kickr snap, kinetic road machine control. Wondering can you offer any advice? Much appreciated Shane.

Noob question here :) if this can only simulate 10% gradient and you're racing on zwift with people using trainers that represent 20% gradient. Does this mean it will give you a huge advantage over them ?

Picked up one of these yesterday, 6 months old still under warranty for £400, cassette included. All good except when connecting to zwift via bluetooth 4k apple, connection shows the same as above at 5:10 but with speed connected no cadence. Is that because it's running through Apple (not sure how the above was connected.)

Nice review again but a little outdated now? 2 years old review and the Flux S is still one of the most popular machines. Time for a new review maybe to see if they have fixed some of the issues you had in this review(hope so)?

If you calibrate your trainer inside the Tacx app and then again inside of Zwift will it change anything or is it not necessary to do both?

I have the fluxs (1st gen) and have trouble about bluetooth signal keeps droping out (on my acer gaming laptop)(i dont have the tacx ant+ antenna, just bluetooth). But, when doing zwift on mobile, no problems at all (until battery drains out lol). Anyone have the same issue or it's just me?

Time for new video: Deep look on coffey maker 2 and allso do i like dyson?😁🤪

I have the Cycleops Power beam pro (wheel on) which is ANT+ only. Is it worth spending another 360 GBP for the Flux S? Any views would be appreciated.

I'm using the Flux too...but the watts shows on my garmin is always more 15w-25w than my Stages Left Power & Vector2s....anyone facing this issue? i tried warm up 10mins, calibrate and also updated the firmwares....but its still showing additional Watts...

Hi, great review. Any tips to making the shifting better on the flux s? I’m having big issues with gear shifting. Thank you very much.

if i may ask one question: will you do a long term test?

Great review! Question about the Hub: If I have two bikes, one SRAM cassette and the other Shimano cassette, will this hub accept either or do I need to swap it out for the specific cassette?

New viewer, former music pro. Can I HIGHLY recommend looking into some simple plug-ins for processing the audio on your vids? Specifically some compression and de-essing would do wonders; your delivery is great, but sound-wise it's spikey and sibilant. It would not be difficult for you to address this.

Great review - thanks v much! I have through-axle so an adapter is annoying. Would you say the wahoo is good value and sector leader?

Local bike shop has discounted end of line flux for £450 & a flux s for £549 - worth the £100 extra?

Hi, for this kind of trainer or kinetic r1 to use with zwift, i need to buy separately an ant+ dongle for pc? Thank you

Hi and thank you very much for your very interesting videos. I am a newbie in this area even if i do road cycling since a decade now, i've never used an indoor training. Considering the lockdown i am now keen in buying one to use also in winter season, and this one is my favourite. Since I only have one bike, a carbon frame Trek, I am a bit worry that Home trainer might stress the frame of my bike. What's your opinion on this topic? I generally think that direct drive trainers are less stressful, but. i really don't know "how much", therefore i'd like your opinion! Thank you in advance!

Just a quick question how do you know what size cassette you need to purchase I’ve just got a carrera karkinos road bike second hand and looking at a smart trainer. Do you use the cassette of your bike or purchase one for this. Only new to the whole sport and turbo trainers and for this particular model do you have to purchase an ANT+ usb to use Zwift with your computer much appreciated

Can anyone tell me if low temperatures have a negativ effect on the Fluxc Trainer? I‘d like to leave it on my enclosed balcony (not heated) Thanks for the answers

Hi do I need to use the tacx ant+ specific usb dongle, or can I use any other ant+ usb dongle? 🙏😬

Quick question: is this a viable trainer in 2022? I want to get a direct drive trainer that won’t break the bank. Any thoughts. Thanks and keep up the great work!

Its this unit or an elite zumo. Dont know what to pick as im new to turbo training. What is the better unit out of the two please? You gave the zumo a more favourable review but the issues with the tacx are possibly well resolved by now.

Dear Shane, My girlfriend is currently on my old trainer a Tacx Bushido. While she enjoys it I am thinking about upgrading her to the Tacx Flux S. Currently she is using the Tacx smartphone app for training. She creates herself workouts and rides them while watching Netflix. So from my point of view Tacx is a good choice here because the app delivers what she needs for free. Seems like Wahoo can’t do it without third party integration and Elite seems to have a subscription model. My goal is still to have her ride with me on Zwift or similar. From your point of view would it make sense to upgrade from the Bushido to the Flux S? Have fun in Amsterdam. Unfortunately I recognized too late that you will be at Rays party with Von otherwise I would have signed in.

How about trying to calibrate it from Zwift, On the startup menu there is the option to do that...

Why do you use a front wheel raiser? I thought that was not needed for the flux?

i got this and i need to install for my bf surprise birthday gift what gear/tool i need? hope can give me some advise thx

Is it worth it to buy Flux S?

I wonder if flux s smart and flux 2 smart are able to reproduce the feeling of road condition in zwift like neo smart. Do they convey the feeling of pebbles, slight steps and level difference on road?

Thanks for the video. What additional equipment do i need except from the cassette?

Hi shane! It's me again hahaha, is the FLUX S a good option for 2-3 time ride a week, today in 2022? Thanks!

So you don't get the software included? Only a month's trial..AND ...you'll need Zwift membership? Is that correct? Thanks.

Is the Flux 2 worth the extra $150 (usd) over the Flux S ???

hi Shane. I have the opportunity to buy the Saris H2 for $750 used. but i was also considering the Flux S for $815 new, with tax. which would you recommend?

If you only had one trainer to use which one would you pick

Will this work with road bike and mtb 29er bike too?

the sticky feeling is due to the resistance of the unit is too high even at the lowest setting. the unit would free spin for 5 seconds only no matter how hard you push it. it not good compared to other trainers.

Shane, have you been watching the 'This Old Tony' KZfaq channel? It looks like he's inspired your b-roll.

Does it come with the tools to install the cassette on the trainer?

Is there anyone who can run Tacx app via Android ???

This just popped into stock on a website, but considering the extra cost of a thru axle adapter and a cassette i'll hold out for a kickr core.

Shane any ideas why, after I've done a workout on Zwift in ERG mode, the next time I do a group workout the trainer does not adjust resistance on hills?

Is the Flux S worth the extra money over the original Flux??

Does the trainer work with no power? Can you use it without an app/computer?

How do you connect it to a big screen?

Kind of off-topic, but have you ever ridden 53-42 chain-rings? Or 55-42? I'm kind of tempted to buy Ultegra or Dura-Ace cranks with close ratios like that and using a 14-34 cassette at the back. Btw, Shimano now make a 14-28 11s cassette in the R8000 range. I'm tempted to try it, since I don't care about downhill speed, and it would give lovely usable and efficient gears with great chain-lines in the big ring.

I don't know why anyone would buy one of these. Having recently purchased one, I was surprised to discover that the Flux line only connects with the Tacx Training App and cannot be used on Zwift. I emailed their customer support to see if I could somehow purchase an unlock to be able to hook up to Zwift, but they don't answer emails. It is no better than my old fluid trainer that I rode while pairing my bike's power meter to Zwift. There "controllable" features are only available on Wahoo trainers, not from Tacx.

Kinda sounds like you're saying "Fluxus". Oooh, if they called it that they could follow Final Fantasy spell naming conventions! Flux, Fluxus, Fluxaga!
