If you’re comparing the Merach R50 Pro vs Concept2 RowErg, the real question isn’t which rower is better. The Concept2 wins more of my rounds. The real question is whether you’ll actually use what the extra $430 buys. Both are air rowers built on the same idea, and one costs about $560 while the other costs about $990.
I’m a NASM-certified personal trainer, and I’ve compared these the way I’d help a client choose: what’s the same, what’s different, and which differences matter for your weight, your budget and how often you’ll row.
Searching for the Merach R50 vs Concept2 RowErg? The R50 Pro is Merach’s updated R50. A reviewer who tested both says it rows much like the original, and Merach sells it with an upgraded backlit monitor; the older R50 has a basic LCD display. This comparison covers the R50 Pro, so the monitor details below don’t apply to the older model.
Quick verdict
- Get the Merach R50 Pro if you’ll row a few times a week to get fit and the budget matters. It gets you most of the way there for about $430 less. Check today’s Merach R50 Pro price →
- Get the Concept2 RowErg if you want workout numbers you can compare anywhere, you weigh close to 350 lb or more, or you’ll row most days for years. Check today’s Concept2 RowErg price →
- Spending under $560? See my budget rowing machine roundup for cheaper picks.
Final score across seven rounds: Concept2 4, Merach 1, even 2. The one round the Merach wins is price, and for a lot of buyers that’s the whole decision.

Prices change often; check today’s prices. Amazon lists the Merach at 440 lb, but Merach’s own site says 350 lb, and I go by the manufacturer.
What’s the same
Before the differences, here’s what you get with either one:
- Air resistance. A fan spins as you pull. The harder you pull, the more it pushes back, so the machine matches your effort.
- An adjustable damper to make each stroke feel lighter or heavier.
- About 8 feet long and 2 feet wide when you row.
- Split-in-two storage. Both come apart into two pieces to stand in a corner, and both roll on wheels.
- No subscription needed. Both work straight out of the box.
So you’re not choosing between two kinds of rower. You’re choosing how much you want to pay for the extras on top.
1. Price: Merach saves about $430
The Merach R50 Pro typically sells for about $560 (Merach lists it at $559.99). The Concept2 RowErg is about $990 with standard legs. That’s a gap of about $430, and for many buyers that settles it.
Trainer’s test: if $430 is money you’d rather put toward a mat, shoes or a few months of a gym membership, that’s a real reason to choose the Merach. Prices move, so check both before you decide.
Winner: Merach.
2. Weight limit: Concept2 has 150 lb more room
Concept2 rates the RowErg for 500 lb, as tested by Concept2. Merach’s own website lists the R50 Pro at 158 kg, which is about 350 lb. You may see 440 lb on Amazon, but I go by the manufacturer’s number.
Trainer’s test: if you weigh close to 350 lb or more, get the Concept2. It’s the one built for you, with room to spare.
Winner: Concept2.
3. Monitor and data: where the Concept2 earns its price
The Concept2’s PM5 monitor gives you accurate numbers you can compare with any other Concept2. That’s why gyms, rowing clubs and online challenges use it: a 2,000-meter time on your PM5 means the same thing as one on a gym’s. It connects over Bluetooth and ANT+, to Concept2’s free ErgData app and more than 40 others.
The Merach has a backlit display with pace, watts and more than 20 workout modes, and it connects over Bluetooth to the free Merach app (some content is behind a paid tier) and Kinomap. One thing to know before you buy: a hands-on reviewer found its screen goes blank if you pause too long in manual mode, which resets your workout.
Trainer’s test: if you track progress, do erg tests or CrossFit, or train with a coach who asks for your splits, this round matters more than any other. If you just want to sweat for 20 minutes, it matters much less.
Winner: Concept2.
4. How they row: even
Both use a fan, so both feel like a real rowing stroke, with resistance that builds as you drive with your legs. The Merach uses a 32-blade fan and a 10-level damper. A hands-on reviewer said it “feels very similar to a gym rower,” with a handle that feels like the Concept2’s.
Both also make the same kind of whoosh. Air rowers are louder than magnetic ones, so if you share walls, keep that in mind with either.
Trainer’s test: on any rower, technique matters more than the machine. Drive with your legs first, then lean back, then pull with your arms. Reverse it on the way forward.
Result: even.
5. Seat and setup: even
The Merach comes with a contoured, foam-padded seat. The Concept2’s seat is molded, not padded. Some people like it as it is, and some add Concept2’s own optional seat pad.
The Concept2 seat sits 14 inches off the floor. For about $165 more (about $1,155 total), you can get Tall Legs, which raise it to 20 inches. That’s a real help if getting up and down from the floor is hard on your knees or back.
Trainer’s test: comfort is personal, and no one has tested these two seats side by side, so I’m not scoring comfort. If getting down to the floor is a struggle, the Tall Legs option is a genuine reason to look at the Concept2.
Result: even.
6. Warranty: Concept2 covers the frame for 5 years
Concept2 covers the frame for 5 years and parts for 2. Merach gives you 1 year, plus 1 more when you register the rower, so 2 years in total.
Trainer’s test: if you buy the Merach, register it the day it arrives, or you’ll only get the first year.
Winner: Concept2.
7. Size and storage: same footprint, Concept2 is lighter
Both are about 8 feet long and 2 feet wide when you row, and Concept2 recommends a 9-by-4-foot space to row comfortably. Both split in two and roll on wheels.
The difference is weight. The Concept2 is 57 lb with standard legs, and the Merach is about 73 lb. One reviewer also found the Merach’s small wheels sink into carpet.
Trainer’s test: if you’ll split it and stand it up after every workout, those 16 pounds add up. If it stays set up in a spare room, they barely matter.
Winner: Concept2.
Final score: Concept2 4, Merach 1, even 2
| Round | Winner |
|---|---|
| Price | Merach |
| Weight limit | Concept2 |
| Monitor and data | Concept2 |
| How they row | Even |
| Seat and setup | Even |
| Warranty | Concept2 |
| Size and storage | Concept2 |
The Concept2 wins on points. But that one Merach win is price, so the real question is the next one.
What does the extra $430 actually buy?
| What you get with the Concept2 | Who it matters to |
|---|---|
| PM5 monitor: numbers you can compare with any Concept2 | Erg tests, CrossFit, teams, coaches, online challenges |
| 3 more years of frame warranty (5 vs 2) | Anyone rowing most days for years |
| 150 lb more capacity (500 vs 350) | Anyone close to 350 lb or more |
| 16 lb lighter (57 vs about 73) | Anyone who splits and stores it after every workout |
What it doesn’t buy is a very different rowing feel. A hands-on reviewer said the Merach feels very similar to a gym rower. So if none of those four things matter to you, the $430 stays in your pocket.
Costs beyond the price
Neither rower needs a subscription. Concept2’s ErgData app is free. The Merach app is free to use, with more workouts behind a paid tier, and Kinomap is a third-party app with its own plans. Either way, you can row, track and finish a workout without paying anything extra.
Who should buy which?
Buy the Merach R50 Pro if you:
- Want a real air-rower stroke for about $430 less
- Row a few times a week for general fitness
- Weigh comfortably under 350 lb
- Don’t need numbers that match a gym’s Concept2
Buy the Concept2 RowErg if you:
- Do erg tests, CrossFit, or train with a coach or team
- Weigh close to 350 lb or more
- Plan to row most days for years
- Want Tall Legs for an easier seat height, or a lighter machine to move

The 20-second test: stop at your first yes
- Do you want numbers you can compare (erg tests, CrossFit, a team, or a coach who asks for your splits)? Get the Concept2.
- Do you weigh close to 350 lb, or more? Get the Concept2. Its 500-lb rating gives you room.
- Will you row most days for years? Get the Concept2. Its 5-year frame warranty is built for that.
- None of those? Get the Merach R50 Pro, and keep the $430.
Exception: under $560. If even the Merach is more than you want to spend, I’ve ranked cheaper rowers in my budget rowing machine roundup.
Before you buy
- Measure a 9 × 4 ft space (both rowers).
- Put a mat down if you have hard floors (both).
- Carpet? Plan to carry the Merach rather than roll it.
- Merach: register it to get the second year of warranty.
- Concept2: decide between standard and Tall Legs before you order.
How this comparison was made
I’m Bishnu Pada Das, a NASM-certified personal trainer (NASM-CPT) and Precision Nutrition Level 1 coach (PN1-NC). Here’s how I put this comparison together:
- Specs come from the manufacturers first. I checked Concept2’s and Merach’s own product pages on October 17, 2026, then Amazon, then hands-on reviews.
- When sources disagree, the manufacturer wins, and I say so. Merach’s site lists the R50 Pro at 158 kg (about 350 lb); Amazon says 440 lb. I use 350.
- I haven’t tested these two side by side. Where I talk about how the Merach feels to row, I’m quoting a hands-on reviewer, and I name the source.
- Rounds are scored on what changes the buying decision: price, weight limit, monitor and data, rowing feel, seat and setup, warranty, and size and storage. Where the evidence is thin or comfort is personal, I call it even rather than guess.
- Prices are a snapshot. They were typical Amazon prices when I wrote this; check today’s price before you buy.
Frequently asked questions
Is the Concept2 RowErg worth $430 more than the Merach R50 Pro?
Only if you’ll use what the extra money buys: comparable PM5 data, 150 lb more capacity, a 5-year frame warranty and a lighter machine. If you row a few times a week for fitness and weigh well under 350 lb, the Merach gets you most of the way there for about $430 less.
What is the Merach R50 Pro’s weight limit?
Merach’s own website lists 158 kg, about 350 lb. Amazon lists 440 lb. I go by the manufacturer’s figure, so if you weigh close to 350 lb or more, choose the Concept2 (rated for 500 lb).
Do I need a subscription for either rower?
No. Both work without one. Concept2’s ErgData app is free, and the Merach app is free to use, with extra workouts behind a paid tier.
Does the Merach R50 Pro feel like a Concept2?
Both are air rowers with a fan and a damper, so the stroke works the same way. A hands-on reviewer said the Merach feels very similar to a gym rower, with a handle that feels like the Concept2’s. The bigger differences are the monitor, capacity, warranty and weight, not the feel.
How much space do I need?
Both are about 8 ft × 2 ft when you row. Concept2 recommends a 9 × 4 ft space. Both split in two to stand in a corner.
What warranty do they come with?
Concept2: 5 years on the frame, 2 years on parts. Merach: 12 months, plus 12 more when you register, for 2 years in total.
Final verdict
The Concept2 RowErg is the better rower. It wins on data, capacity, warranty, and weight. The Merach R50 Pro is the better deal for most home rowers who just want a good workout, and it costs about $430 less. Neither is a bad buy. Pick the one that matches the answer you gave in the 20-second test.
