Revbox-Erg_low-inertia-premium-wind-trainer_complete

Based in New Zealand, newcomer Revbox has developed a premium training solution for cyclists to work on improving both fitness and form. While roller-based wind trainers have always had a reputation for being loud and less effective, this chain-drive revision takes away almost all of the negatives and ends up with the benefits of a low-inertia trainer. Plus, being light and relatively compact makes the Revbox Erg a great solution for pro cyclists, like Lotto Soudal who have just inked a 5-year deal to train with it.

Find out how Revbox appeals to them and to cyclists of all levels after the break, plus pricing…

What makes the Revbox Erg work is that the light air-braking blades and lack of rollers or heavy gearing creates an unlimited range of resistance with very low inertia. This gives a controlled training environment that allows the user to perceive changes in power output and tempo much more easily to help build strength and smoothness. While many trainers seek to reproduce a road feel (with accurate reproduction of the feel of coasting), the Revbox goes the other way to try to build pedaling form and optimize fitness by highlighting inefficiencies.

The Revbox low-inertia solution builds smooth muscle action through the whole pedal stroke by listening to the changing sound of the trainer and feeling the change in resistance. This precise and repeatable feedback makes for effective targeted training, allowing efforts to be methodically reproduced.

By utilizing a standard cassette and the complete drivetrain of a standard bike, plus the fan whose resistance increases with rotational speed, the Revbox offers almost unlimited resistance range. (A 53/11 gear ratio, at a cadence of 50rpm corresponds to an output of 500 watts; and at 90rpm requires 1800 watts!) Different drive ratios are also available optimized for juniors or others seeking lower speeds/intensities. The road and mountain friendly Revbox itself weighs just under 9kg, and with the quick release legs removed is effectively the width of your dropouts (130/135mm) at its widest point.

Starting in January pro team Lotto Soudal will start using the Revbox Erg trainer, including German sprinter Andre Greipel. Revbox sees this partnership with Lotto Soudal as a “huge endorsement about what the Revbox Erg can provide as a stationary cycling trainer” and looks forward to continuing to develop with such top level input.

The Revbox Erg was designed, engineered, and is assembled all in Christchurch, New Zealand. Retail pricing is $1000/900€/650£/AU$1400 with all units shipped direct to consumers for the time being. Update: Revbox has secured a distribution deal with Ridley bikes for cyclists in Belgium, The Netherlands, Germany, France, Spain, and Austria to have easier direct access through the dealer network. An integrated Android app was launched earlier this summer (with iOS maybe another month out) to read power (calculated), speed, cadence while training, based on sensors on the trainer to help get the most out of a Revbox Erg session. It also connects to heartrate monitors, tracks speed and distance, and is designed to upload data to TrainingPeaks and other online training sites.

Lots more info about the trainer, especially the science behind the use of low-inertia training can be found on Revbox’s website.

the fan is in the wrong direction. should be a headwind for cooling 🙂

For 1000$, you can get an ANT+ smart trainer that automatically changes resistance for a program like Zwift or Trainer Road or whatever you fancy. A big giant fan with a speed sensor in it for that much money seems like a waste.

Who cares of its lightweight if its too big to travel with it easily. I’d much rather have a small, heavy trainer. That said, maybe the feel is actually pretty good. Computrainers have never really felt right to me and they’ve never been close in measuring power(for me) when using an additional power meter. Maybe this calculated power measurement is better than computrainer’s ACTUAL power measurement? I’ve seen 50+ watt variables

If they incorporated variable pitch props, they could adjust the resistance automatically for Zwift, etc.

The physiological gains that can be had from training on a low friction, low inertia, but high resistance trainer far exceed that of any existing conventional devices. Those with advanced sports science knowledge understand this.

Im a phd x 3 gents, i love the comments, ive just tried one of these for the last week, comments as follows:-
Bas you obviously have not tried one of these yet, the air blows up your back, keeps you real cool when you putting in the hard training, that is if your fit enough to push this baby.

Bill, im sorry Dude, the Revbox, trains the brain, this then trains the muscles, and if you can activate the muscles better, faster and more efficiently, then you get to use both legs efficiently (this must be the reason why, the likes of Cavendish, Frome, wiggo,) must use ergs, instead of a machine that causes a restriction, then you have to use your brain (like automatics are for LAZY boys) i guess any one wanting to be like the best better by an RB and train like the best (IT will not win you the race dude) and if you don’t understand the RB, i gues you need to ask the RB Boys, go Andre Gripel. (a special thank you to Caddel for telling me about this machine)

Veganpotter, the machine weighs 8.4kg and why would you want to be without the correct trainer, and if you read what the guys have said on the websight, the RB has been professionally Calibrated, upon enquiry it seems like its been done in a professional University Lab, in the vicinity of Cycle New Zealand, they are one of the worlds top Track community’s, lets not miss the little trick box the Boys are doing, a power meter app, surely this will be more accurate, like that of the proverbial, cant wait to get my hand on a RB and app of my own, and watch my legs grow for next years Tour of California.

Velo, Dude, variable pitch props, this thing breaks straight away, just by using the gears it gets harder the natural way, Talk to Hunter Allen Training peaks, he supplied the soft wear that Team sky uses….to win the TDF, talking about this is just Moorish.

Speshy, you just gotta try one, it will be the only piece of kit, im ever going to need ever again, i push this to the limit and it just gives me shit even more, im hooked.

Dsand, i train Paraplegics, people trying to get back in the saddle, injured, just trying to walk, this piece of kit, is for if you want to get fit, just be alive, if your a great person, look further than the end of a beer glass, you might give positive affirmation.

The only downside to this, is i cannot get my hands on one fast enough, as ive been told they have sold out already, that’s just awesome statement of there Credibility, Go the Revbox Guys.
I can wait for my order to come through.

It’s a re-invented BT erg/ Lemond Revolution. Will I be deaf after using it? Using the other two leaves a ringing in my ears similar to the one experienced after a Metallica show, or a speech by John Key, or a trip through the Florida Everglades on one of those airboat thingies.

Laughing Boy: clearly one of your supposed Phd degrees is NOT in grammar. Just talk to us and drop the air of “I have all this education so listen to what I say” OK?

Probably the best way to lose an audience in an online forum is to open up with some crap line about how smart you think you are. If your comments are smart, then you’re smart. if you tell us you’re smart — well, likely you are not.

You can share that with the rest of your buds over at Mensa.

@Truth Ynez, The BT Erg and the Lemond Revolution are completely different devices. The Lemond is high inertia and serves little to provide specific muscular activation while the BT is low inertia and is an incredible training tool. The Revbox is along the lines of a BT but lower inertia again and lighter and easier to transport.

Low inertia can be compared to training uphill or into a headwind while high inertia is like cycling in a tail wind. So imagine cycling at 300 watts into a headwind vs 300 watts in a tail wind. The power output is the same but as the headwind is trying to slow you down more it has a greater affect on the dead spots in the pedal stroke. This is where a low inertia trainer comes into it. It provides a controlled training environment that hill training, or training into a head wind can’t provide. Plus there are further benefits with the amount of resistance, that’s a whole other story, as is the low friction chain interface.

@the boss thanks for the headwind vs tailwind analogy, makes a lot of sense.

Over the past 6 years I have had a few trainers….starting off with a basic magnetic one, then moving into the world of Computrainers and then this year purchasing the Revbox. Firstly, I loved my computrainer, and only looked at this change because it was recommended as a tool which would provide a step change in my cycling. I loved the technology that Computrainer gives you, especially when coupled with ErgVideo and similar apps. I was apprehensive to move to a zero technology based training tool. I have been using the Revbox for a month now, so let me give you my early feedback :
Noise : Its certainly louder than the computrainer no doubt. I dont think this one is for use in the lounge next to a bedroom or whilst watching TV with the family. However, the noise is core to the beauty of this machine. The fan noise clearly indicates how inefficient your pedaling is. Its taken me a month to reduce the ‘whoop whoop’ style pedaling I had (so no engagement through the back end of the pedaling) to a smoother one, but still lots to do. It definately makes you engage the full circumference of the pedaling circle.
Resistance : This thing absolutely outperforms the Computrainer! Big call in from me and its my opinion, but I have to work so much harder because I cannot use the inertia generated with the flywheel in the computrainer to help me through the back end of the pedal stroke. You have a flat spot, or a lazy point, you feel the change immediately, there is not hiding. I certainly cannot out power it either using the standard gearing config either. I would be interested in the reviews by the pro team members next year, but I certainly cannot out power the machine.
Technology : Well, I love technology. The change to none had me a little apprehensive. After a month, I have surprised myself at how I have changed though. I use time and heart rate only (I have a good sense of my own cadence though). Not worrying about power and focusing on feel and heart rate, have freed me up to focus on a smoother and more efficient cadence. I do have a powermeter in my training wheel, so when on the road I get my watts then, but all my indoor sessions are now focused on my perceived effort and smoothness. So, its not really an issue any more for me. I do acknowledge the gap though when it comes to the gamification of cycling, which is taking the world over now, and I would hope that Revbox have that in the back of their mind because without that, they might lose customers down the track.
Weight / size : I dont plan to travel with mine, but its pretty big, so if flying with a bike that would be awkward. Putting it in a car, no issue I guess, but really, I dont consider weight and size particularly important when choosing an indoor trainer….they are usually pretty static devices. Maybe ask the pro team next year how they travel with theirs…

So to wrap up….I am convinced that this is a great training tool. I’m only a month into using it solely, and am really happy with how it has already changed my efficiency, and I can feel the strength coming through as well. If you can get one….you wont regret it…..

I got one of these boys this Summer. Game changer. After a winter of training with a flywheel I noticed some weaknesses when I was back out on the road. I developed very un-evenly during the winter, even with a serious strength program, as a result of a flywheel for my meat and potatoes. That’s when things clicked for me, I knew I needed something else.

I found the RevBox. It’s way more than I expected. First ride on it was brutal for my ego. 2 weeks in and my legs were getting beaten up all over the place. After 2 months on it I’m way stronger and also see a path for growth that I didn’t before. Some guys here are mentioning how it trains the brain etc. I will say this, it requires focus to use properly, it requires a retraining of how you approach your training. Without focus you stall out or go back to a whoosh-whoosh-look-at-me-mom-aren’t-I-the-best sort of thing.

I dragged mine all around Europe too. With my bike! It’s light enough to do. It became that important of a training tool. If the thing could fit in my bike box that’d be cool but I would not sacrifice the quality of the tool for that. NEVER. The thing is a precision instrument. The wattage is dead-on repeatable for a given gear and cadence. If I had to choose between a power meter and a revbox, it’s the rev box (and a cadence sensor).
