Product Description

At CycleOps, we realize at the heart of every cyclist is a better cyclist. Not better as defined by speed necessarily, rather by progress, improvement, the setting of goals and reaching them, and by having fun along the way. Coming from a manufacturer of indoor cycles and trainers, we understand that it may sound a little self-serving to say that a trainer can and should be an integral part of this self-improvement journey. But it's true; trainers are extremely efficient and effective, and can be used throughout the year to help you reach your fitness goals. Add CycleOps Virtual Training and indoor training no longer needs to be viewed as an act of basement torture. We'd even go as far as saying that indoor training can now actually be, well, fun.

23 customers mention11 positive12 negative

Customers have mixed opinions about the resistance of the bicycle trainer. Some mention that it gives the right amount of resistance in any gear, while others say that it does not provide as much resistance as they expected. The oil heats up and causes the resistance to change a lot through the workout. The resistance is speed dependent and the maximum tension is not extremely tough.

"...My ONLY gripe is that maximum tension isn't extremely tough...." Read more

"The product works great easy to set up has great resistance. Resistance is adjusted by switching gears. The noise level is just above loud talking...." Read more

"...I was surprised and concerned that it did not come with any paperwork. But being good stewards of the environment it can download it on your phone...." Read more

Winter workout
This is going to be my winter workout because my local gym is still closed. The Fluid2 just arrived & it was almost easy to assemble. The L-bracket (bolt) meant to engage the tightening knob was difficult to insert and the instructions really didn't tell how to put it in place. The key is to point the long end of the bolt down toward the floor and slip the smaller end up into the piece of metal meant to hold it in place. Other than that it was all pretty easy. Can't wait to try the new trainer. I had heard that some folks felt it was loud when pedaling. I really didn't feel it was bothersome. It has to make some noise because of the friction caused by the tire. Also, I didn't spend bucks on a special "trainer tire". I just got the local bike shop to put a normal street tire on the rear wheel of my mountain bike and it works fine and didn't cost much. Happy riding!

I had the Blackburn and it broke after intense use....suddenly you have no trainer and you need one, so, I ordered what everyone rated as the best....and it is! I thought my previous workout were tough but, this takes the cake, or, more precisely, takes the cake right out of you, but faster! It is not hard to assembled though. What is a little tricky is getting the bike into place, but, when you do get it, it stays in place....take your time and don't give up....What you end up with is a very hard and fluid ride....you use the know to adjust to your preferred level, and then you use the bike shifters to either raise or lower the degree of difficulty, just like as if you were riding....but by the time you are ready to rough it out, believe me, this bike will give you a very, very strong workout....and is deceptively effective, at first, then it's just really hard, so, you end up lowering the gears to make it easier....otherwise it's like climbing the French Alps....it's worth it, it's well-built....you need some sort of block for the front tire to level yourself off....and, a mat under the bike and trainer if only for neatness....I believe it is the best and will leave you thoroughly worked-out....it's made in America and made really well....fill out registration onlne and save the box....it is a lifetime warranty. And it looks awesome to, and runs as quiet as can be and again, very solid....I love it!

5.0 out of 5 stars Helping my training
Reviewed in the United States on March 9, 2018

This is great. I haven't tried others - but it was easy to set-up, it is standard and easy to find in the various on-line programs - I've used Zwift & TrainerRoad so far, and it has really been helping a lot with my training when I can't get in an outdoor ride.

Questions that I had starting out (beginners starting out):
- Do I need anything else to ride? You need a block for your front wheel. A basic one is maybe $6 on Amazon. And probably a mat to protect your floor, mine was $26 on amazon.
- Is there anything else I don't need but I "need"? I highly suggest speed and cadence sensors (Mine were ~$55 on amazon). You'll need that to hook into other programs - like Zwift etc. I got ones that hook up to my watch. If you're doing them with your computer, you'll need a USB extension cord and an ANT+ dongle too (~$20-$25 for both, Amazon). Also - a fan is REALLY nice ... I use a tiny "desk fan" one and it's great.
- What programs should I use? I personally suggest trying them all. Zwift has a 1 week free trial, Rouvy has a 2 week free trial and TrainerRoad is only $12 per month & easy to quit at the end of that month ... give them all a try.
- That quick-release bar on the back tire that I have to use in this...1st, does it come with this? 2nd, can I use that outside? Yes and yes. Once you change it, just leave it in. I didn't know and switched back and forth the 1st 3 or 4 times and, while it's not a great big pain ... it's an extra step and it really isn't necessary ... the CycleOps one can just stay in.

Enjoy & get to training!

4.0 out of 5 stars Smooth and quiet
Reviewed in the United States on January 19, 2017

For many years I would ride wind resistance rollers in the winter but now I'm blind in one eye and have no depth perception so the rollers have become very difficult, not to mention riding outdoors. I decided to buy this trainer as a replacement.

First, this is not difficult to put together. You almost don't even need instructions. It's simple and has only two bolts, but yeah, the instructions aren't the best and there really should be a drawing that shows the fluid unit in place, because the fan goes on the other side from the fan-only unit that is pictured so I guess it could be assembled backwards. Not worth taking a star off for. If in doubt look at the photo on this page.

I agree with one reviewer whose frame wasn't jigged up straight when it was welded. Mine doesn't sit perfectly flat without weight on it, but is fine when I get on it. It's lopsided by about 1/8" and that costs a star because there's really no excuse when it's such a simple device not to have everything line up well when one is paying a premium price for this unit, though I imagine about 85% of that price is for the resistance unit and the warranty. I didn't see it as a reason to return it since they are all probably a bit variable.

The clutch nut does what it is supposed to, but I don't need mine as tight as the recommended 2 1/2 turns. The rear wheel locking device is pretty clever and works perfectly.

On the major plus side, and this is the main reason I spent some serious money on this trainer, it is super quiet compared to a wind resistance trainer. I could watch videos without any need to turn up the volume. and it gets 5 stars for that.

This is not a long term test report because I just got it and am sharing initial impressions. It will get a lot of use so I will update later.

This is the 3rd of these type trainers I have bought and is far away my favorite. I don agree with those who say it is loud. I bike while watching TV and I don't have the have the volume "cranked up" any more. It was easy and straight forward to put together (although the instructions in the box were for a different model), that made no difference, it is a pretty simple machine). The pressure is smoother than the others I have had and I like the fact it gets a little harder to peddle as the liquid warms up. I am a fan.

A bit pricey but just fantastic. Stable, well made and pretty quiet as long as you run a smooth tire. Easy to set up and easy to use. Doesn’t require much balance, unlike the roller style trainers. That may be a plus or a minus depending on you.

5.0 out of 5 stars Quick initial review.
Reviewed in the United Kingdom on January 28, 2014

Very pleased. Setup was quick- about 10 minutes plus time to change the spindle.
Noise levels are relative of course. I can cycle and watch TV, but not with anyone else in the same room. (Though I am not using task specific slicks but fairly smooth continental gand prix tires - so a lot of the noise may be coming from this).

Plusses:
- very smooth
- once you have set the resistance the power required to pedal increases as you change the bikes gears.
- very stable, even going flat out standing up there is no sensation of wobble.

Negatives (perhaps just niggles really):
- it was a little tight to get my bike in, perhaps its just practice or will get easier when the front wheel holder arrives.
- did not make clear on amazon that you have to change the spindle on the rear wheel, while not a big issue it's worth pointing this out
- if you get the resistance wrong you have to get off to change it and there is no easy way to see how much resistance you have. Again this will probably get easier with experience but you should expect to have to get off about 15 mins into a ride to readjust until you get used to judging by how much you have compressed the tyre.

To help other cyclists: I am mainly a mountain biker happy to do 30-75 miles offroad, on a road bike I tend to do less distance (hence this purchase). On Strava I am usually in the top 25% for mountain bike segments and about the 50% mark for roadbike segments.
