The benchmark

Best Concept2 Rowing Machines

There are two Concept2 machines worth choosing between, and the difference is six inches of seat height. Here is when that matters.

Concept2 makes essentially one rowing machine, and it sells it with two different leg heights. That is the whole product line, and it has been more or less the whole product line for thirty years.

The RowErg is 96 inches long and 24 inches wide, weighs 57 lb with standard legs, and carries a published 500 lb maximum user weight — the highest figure any manufacturer on this site prints. Concept2 also publishes a recommended space of 9 ft by 4 ft, which is unusual: almost nobody else tells you the difference between the machine’s dimensions and the floor it needs.

It has no subscription. The PM5 monitor records every session on its own, ErgData is free, and the machine works identically whether you connect it to anything or not. Over five years that single fact is worth more than most of the features the connected brands charge for.

Below: the two Concept2 configurations, plus the two machines we would genuinely consider instead and why.

In detail

Every pick, and what is wrong with it

Each machine below gets the same four things: what it does well, what it does not, the five-year cost of owning it, and the case for buying something else instead.

Concept2 RowErg rowing machine

1. Best overall

Concept2 RowErg

The machine every other rowing machine is measured against, and the only one here with no subscription, a 500 lb user limit and a five-year frame warranty at under a thousand dollars.

Five years of ownership: $990 — all of it the machine, none of it a subscription. See the full table

Floor space: about 9.0 ft by 4.0 ft once you allow for handle travel and elbow room — roughly 36 sq ft.

What is good

  • 500 lb published user capacity — the highest figure any manufacturer on this page prints
  • No subscription, ever. The PM5 records everything on its own and ErgData is free
  • Separates into two pieces in seconds for storage; front and rear sections stand upright
  • Five-year frame warranty, and a parts supply chain that still serves machines from the 1990s

What is not

  • 96 inches long in use, and Concept2 recommends a 9 ft x 4 ft footprint — it is not an apartment-corner machine
  • Air resistance is the loudest kind. Concept2 publishes no decibel figure and neither do we
  • The 14-inch seat is low; getting up off it is a real consideration if your knees are the reason you are rowing

Skip this one if: Skip it if your floor space is under 9 feet in one direction, or if you share a wall with someone who sleeps early — this is the loud one.

Concept2 RowErg with Tall Legs rowing machine

2. Best for stiff knees

Concept2 RowErg with Tall Legs

The same machine with the seat 6 inches higher. That one change is the difference between a rower you can get off unaided and one you cannot.

Five years of ownership: $1,550 — all of it the machine, none of it a subscription. See the full table

Floor space: about 9.0 ft by 4.0 ft once you allow for handle travel and elbow room — roughly 36 sq ft.

What is good

  • 20-inch seat height instead of 14 — close to a dining chair, so you stand up rather than push up off the floor
  • Identical 500 lb capacity, PM5 monitor and no-subscription position as the standard RowErg
  • Easier transfer on and off makes it the sensible pick for older rowers and anyone rehabbing

What is not

  • Concept2 publishes 68 lb with tall legs against 57 lb standard — 11 lb more to move
  • Stored footprint grows to 27 x 47 x 54 in
  • Costs meaningfully more than the standard-leg model for one dimensional change

Skip this one if: Skip it if you have no trouble getting off a low seat — you are paying extra for height you do not need.

MERACH NovaRow R50 Pro rowing machine

3. Best cheaper alternative

MERACH NovaRow R50 Pro

The closest thing to a Concept2 layout at roughly half the money — 95 inches, a 32-blade fan, ten resistance settings and a frame that splits for vertical storage.

Five years of ownership: $500 — all of it the machine, none of it a subscription. See the full table

Floor space: about 8.9 ft by 4.0 ft once you allow for handle travel and elbow room — roughly 36 sq ft.

What is good

  • Full 95-inch competition-style geometry rather than a shortened budget rail
  • Frame separates into two sections and stores vertically
  • Ships 90% pre-assembled with a competition-style monitor and 20+ training modes

What is not

  • MERACH publishes no user weight limit for this model, which matters more on an air rower than most
  • Nothing like Concept2's parts availability if something breaks in year six
  • At 95 inches it needs the same floor as the machine it is undercutting

Skip this one if: Skip it if you were buying an air rower specifically for Concept2's decades-long parts support — that is the thing the discount is buying you out of.

Assault Fitness AssaultRower Pro rowing machine

4. Best commercial alternative

Assault Fitness AssaultRower Pro

A commercial-gym air rower that folds, runs on no electricity at all, and asks nothing of you monthly — built for people who train hard rather than watch classes.

Five years of ownership: $999 — all of it the machine, none of it a subscription. See the full table

Floor space: about 8.7 ft by 3.8 ft once you allow for handle travel and elbow room — roughly 33 sq ft.

What is good

  • Dual stage chain-and-belt drive, built for the abuse of interval work
  • Completely human-powered — no mains socket needed anywhere near it
  • Folds down for storage despite the 109 lb commercial build

What is not

  • 109 lb is a lot of machine to reposition, folding or not
  • The console is functional rather than rich; there is no class library and no app ecosystem
  • Assault publishes no user weight limit on this listing

Skip this one if: Skip it if you want guided workouts on a screen — this machine has no opinion about how you train.

How to choose

What actually decides this

Standard legs or tall legs?

This is the only real decision, and it comes down to one number.

The standard RowErg has a 14-inch seat height. The tall-legs version has a 20-inch seat height. Fourteen inches is low — lower than most sofas, well below a dining chair. Twenty inches is roughly chair height.

If you can get up off a low seat without using your hands, buy the standard machine. If you cannot, or if getting up is the part of the session you are dreading, the tall legs are worth the difference. Concept2 publishes the trade: 68 lb instead of 57 lb, and a stored footprint of 27 x 47 x 54 in instead of 25 x 33 x 54 in.

Everything else is identical — same flywheel, same PM5, same 500 lb capacity, same five-year frame warranty.

The inseam question Concept2 does answer

Concept2 states that users with an inseam of 38 inches or more may require an extra-long monorail. That is a genuinely tall rower — roughly 6 ft 5 in and up, depending on proportions — but if you are in that range it is the single most important line on the spec sheet and almost nobody else publishes an equivalent.

Measure your inseam before you order. It is a two-minute job and it is the difference between a machine that fits you and one you row at a compromise on for a decade.

What you are paying for

The machine is not cheap, and three of the things it buys are not visible on a spec sheet.

Comparable numbers.The PM5 is the sport’s common language. A 2,000m split recorded on one means the same thing in every gym, every online league and every erg test in the world. No other monitor has that.

Parts.Concept2 still supplies components for machines built in the 1990s. Chains, seats, monitors, footplates — all available, all fitted with hand tools. That is why used RowErgs hold value the way they do, and it is the real answer to “why not buy the $500 air rower?”

Resale. A consequence of the above rather than a feature, but a real one. This is close to the only machine in the category with a functioning used market.

The honest case against

Two things, and neither is small.

It is 96 inches long, and it needs 9 ft by 4 ft. That rules it out of a great many rooms. It separates into two pieces in seconds, which helps, but the front section is still four feet of machine to store somewhere. If your space is the constraint, the apartment roundup is the more useful page.

It is the loud one. Air resistance means a fan, and a fan makes noise. Concept2 publishes no decibel figure and neither will we. If you share a wall or a floor with someone, a magnetic machine is the honest answer and it is not a close call.

The alternatives we would actually consider

The MERACH NovaRow R50 Pro gives you 95 inches of air rower with a 32-blade fan and a competition-style monitor at roughly half the money. What it does not give you is the parts catalog, the 500 lb rating or the comparable numbers. If you are certain you will still be rowing in five years, that gap is what the Concept2 premium is for. If you are not certain, the R50 Pro is a reasonable way to find out.

The AssaultRower Pro is the other direction: a heavier, commercial-spec air rower with a dual chain-and-belt drive that folds, runs on no electricity at all and asks nothing of you monthly. It is built for interval work rather than steady state, and it is 109 lb of machine.

Straight answers

Questions people actually ask

Should I buy the Concept2 RowErg with standard or tall legs?

Standard legs if you can get up off a 14-inch seat comfortably; tall legs if you cannot. The tall version raises the seat to 20 inches, roughly chair height, which makes getting on and off far easier for stiff knees or hips. Everything else about the two machines is identical, but the tall version weighs 68 lb against 57 lb and has a larger stored footprint.

How much space does a Concept2 RowErg need?

Concept2 publishes a recommended space of 9 ft by 4 ft, against a machine that measures 96 in by 24 in. That gap - a foot of length and two feet of width - is the clearance for handle travel at the catch and elbow room at the finish. It is the only manufacturer figure of its kind in the category, and it is why we apply the same relationship to every other machine on this site.

Does the Concept2 RowErg need a subscription?

No. The PM5 monitor records every session on its own and Concept2's ErgData app is free. The machine functions identically whether it is connected to anything or not. Over five years that is worth roughly $3,000 against a machine with a $50/month membership, which is the single biggest number in our cost comparison.

What is the Concept2 RowErg weight limit?

Concept2 publishes 500 lb, and states it as tested by Concept2. That is the highest published capacity of any machine on this site apart from the Aviron StrongGo at 507 lb, and considerably higher than the 250 to 400 lb figures typical of budget machines.

Is the Concept2 RowErg worth the money?

It depends entirely on how long you will keep it. Against a $500 air rower the premium buys a 500 lb rating, a five-year frame warranty, parts availability measured in decades, a functioning used market and a monitor whose numbers other rowers recognize. If you are rowing in five years, that is good value. If you might not be, buy something cheaper and find out first.

How tall can you be to use a Concept2 RowErg?

Concept2 does not publish a maximum user height, but it does publish the number that matters: users with an inseam of 38 inches or more may require an extra-long monorail. Measure your inseam rather than your height - proportions vary enough that height alone will mislead you.

The honest part

What we did not do

We have not rowed on these machines. We do not own them, there is no test lab here, and nobody writing this holds a coaching certification. Every ranking on this page is an argument from published specification and buyer fit, not from a stopwatch.

What we did do is read each manufacturer’s own published figures, record the ones they decline to publish, compute the floor space and the five-year cost, and date all of it. The full method is here so you can check our working or disagree with it.
