Model 670D Air & Magnetic Dual Resistance Rowing Machine with LED Display — Wholesale OEM/ODM, Bulk Supply, Factory Direct Export & Private Label for Distributors, CrossFit Boxes and Commercial Gyms

The Model 670D is the heaviest-duty rower in the 670 series, and it is built around a different proposition from the air-only and water models in the same catalog. It combines air and magnetic resistance in one flywheel, supports users up to 200 kg, and carries an LED console instead of an LCD. The result is a machine that covers the full weight range of an adult membership without a second equipment tier, and that gives instructors two separate controls over the feel of a workout: the self-regulating air curve and a fixed magnetic load on top of it.

Full Specification

How Dual Resistance Actually Works

A single-resistance rower gives you one variable. Air resistance rises as the user pulls harder. Magnetic resistance stays where the dial puts it. Each is useful. Neither on its own answers every programming requirement a commercial facility faces.

The 670D runs both systems together. The air side provides the responsive curve — pull harder and the flywheel pushes back harder. The magnetic side adds a fixed offset underneath it. The user can set a base load for steady-state work, then let the air component handle the interval peaks without touching a control.

For a studio running programmed classes, this separation is the practical advantage. The instructor sets a magnetic level for the room and calls out stroke-rate targets. Athletes adjust effort against the air component. No one is walking the floor changing individual machine settings mid-session.

The 200 kg Load Rating

The 670D supports 200 kg. That figure is the highest in this product range and places the model in the heavy-commercial category rather than the standard-commercial one.

A 200 kg rating removes a support issue most gyms encounter eventually: the heavy member who cannot safely use standard cardio equipment. With the 670D on the floor, that member is covered. The frame, seat carriage, footplate assembly, and rail geometry are all specified to the higher load, so the rating is not a sticker claim based on the frame alone.

For distributors, the commercial argument is equally direct. Facility operators purchasing equipment under institutional procurement guidelines look for a minimum five-year frame warranty and a 180 kg to 200 kg user capacity as standard for heavy-use cardio. The 670D clears both thresholds.

LED Display Versus LCD

The 670D carries an LED console. It is a different choice from the LCD head units on the air and water models, and the differences are operational rather than cosmetic.

The digits are large enough to be read from a standing position beside the machine. In a 24-hour facility or a dim studio, that matters more than feature count. LED is also solid-state — there is no backlight tube or panel to fail, which removes one of the common console failure modes.

The trade-off is power. An LED console requires either a mains connection or a self-generating flywheel system. The 670D uses a hybrid drive arrangement that assists console power from the flywheel, removing the need for a wall outlet.

Footprint and Floor Planning

The assembled dimensions are 2710 × 620 × 995 mm. The length is greater than the 670B because the 670D uses a longer single rail to accommodate the heavier user range and the dual flywheel assembly.

The height of 995 mm includes the upright console and front foot assembly. The machine folds at the rail midpoint and stands on its end for storage, with transport wheels on the front foot.

For a facility laying out a cardio zone, the operative figure is the 620 mm width. A double row of rowers can be placed 1.5 m apart center to center, allowing one user to enter and exit without crossing another user's rail. That spacing is tighter than the 2 m commonly recommended for treadmills and ellipticals, which makes rowing a high-density cardio option.

Packaging and Container Loading

The carton is 1420 × 420 × 570 mm and 37 kg gross. The 32 kg net weight is 8 kg lighter than the 670B, despite the higher load rating and the dual flywheel.

That loading density is the strongest logistics argument for the 670D. At 37 kg gross per carton, a full 40-foot container sits well under standard weight limits even when fully loaded, so the buyer is never forced to leave cube unused for weight reasons.

The carton format also reduces shipping damage. Wooden crate packaging adds 4 to 6 kg and 60 mm to one dimension; the 670D ships in carton as standard and meets ISTA 1A drop-test standards.

Customization and OEM Program

Production capacity is 8,000 units per month. Stock orders ship in 15 to 30 days. Custom color or console orders require 30 to 45 days. CE, RoHS, and ISO 9001 documentation is supplied with every order. HS code 9506.91.19.00 applies.

Pricing Structure

For context, verified supplier listings place dual air-magnetic resistance rowers between USD 179 and USD 246 per unit at single-piece pricing, with volume pricing reaching USD 115 to USD 120 per unit from 50 pieces on entry-level foldable configurations. Premium commercial dual-resistance machines at retail reach USD 3,995, and mid-tier commercial units sit between USD 575 and USD 1,799.

The 670D is positioned in the wholesale middle ground: above the entry-level foldable units, below the premium commercial tier, and with the 200 kg load rating that the budget category does not carry.

Payment terms are 30% deposit with order confirmation and 70% against bill of lading copy. Letters of credit are accepted from 500 units. Shipping terms are FOB Xiamen or Ningbo.

Where the 670D Sells

Heavy-commercial gyms and municipal fitness centers​ are the primary market. The 200 kg rating and the three-year frame warranty meet institutional procurement requirements, and the dual resistance system supports both casual members and programmed classes on the same machine.

CrossFit boxes and HIIT studios​ use the air component for interval work while keeping a fixed magnetic base load for strength-endurance sessions. One machine covers both program types.

Hotel groups and serviced apartments​ benefit from the lower noise level of the magnetic assist. A pure air rower generates noticeable fan noise during sprint intervals. The magnetic component smooths the curve and reduces peak noise without removing the air feel.

Fire, police, and military training facilities​ need the 200 kg capacity. Recruit populations include users well above the 160 kg limit of standard rowers, and a single 670D model can cover the full roster without a second equipment tier.

Rehabilitation and physiotherapy clinics​ can use the fixed magnetic levels to set a precise low load for early-stage recovery, then add air resistance as the patient progresses. This graduated approach is not possible on a pure air machine.

Distributors building a full catalog​ should place the 670D above the 670B and below a smart-connected commercial unit. The three models cover performance, heavy commercial, and connected segments without overlapping features or price points.

Market Context

The global rowing machine market is valued between USD 1.21 billion and USD 1.37 billion, with projected growth between 4.7% and 5.8% compound annual growth. Air rowers hold the largest segment share at roughly 33% of the market, while residential demand accounts for approximately 58% of market expansion and commercial gyms contribute around 44%. North America represents about 40% of regional market value.

Hybrid air-magnetic rowers are a smaller but faster-growing slice of that total. They solve two specific objections at once: air rowers are too loud for home use, and magnetic rowers lack the responsive feel competitive users want. The 670D is built for that crossover buyer.

Frequently Asked Questions

Is the 670D a commercial machine?

Yes. The frame carries a three-year warranty, the components carry one year, and the 200 kg load rating places it in the heavy-commercial category.

Does the LED console need a wall outlet?

No. The console is powered by the flywheel through the hybrid drive system. No mains connection is required.

Can the air and magnetic resistance be used independently?

The air component is always active when the flywheel spins. The magnetic component is adjustable from the console. Setting magnetic resistance to its minimum leaves the air curve effectively unchanged.

What is the difference between the 670D and the 670B?

The 670B is air-only with a 160 kg rating and an LCD monitor. The 670D adds magnetic resistance, raises the load rating to 200 kg, and uses an LED console. The 670D is 8 kg lighter despite the heavier specification.

How quiet is the 670D compared with a pure air rower?

The magnetic component reduces peak fan noise. It is not silent — the flywheel still moves air — but the operating volume is lower than a pure air machine at the same stroke rate.

Does the console track heart rate?

The LED console supports pulse readout with a compatible chest strap. Confirm strap compatibility with the supplier before ordering bundled packages.

What is the tallest user the 670D accommodates?

The longer single rail and 995 mm assembled height accommodate users up to 200 cm in height. The 200 kg load capacity covers the upper range of adult users without a second equipment tier.

Is assembly required on delivery?

Partial assembly. The front foot and console attach with four bolts, and the drive connects with a master link or belt link depending on the production batch. One person completes the work in 20 to 30 minutes.

What spare parts are included with an order?

One percent of consumable parts is included free with each container: drive belts or chains, master links, seat rollers, console batteries, foot straps, and decals. Additional parts ship within 72 hours.

Can the 670D be paired with the 667B water rower in the same container?

Yes. Mixed-container loading is supported. A typical configuration combines 400 units of the 670D with 100 units of the 667B water rower and 60 units of an air bike in a 40-foot container without exceeding weight limits.

Ordering and Samples

Sample units are available at the 1 to 9 unit price band. Freight is borne by the buyer. A full specification sheet, frame color chart, carton dieline, and console layout file are supplied before production begins.

For a distributor building a first container, the recommended configuration is 400 units of the 670D with logo applied, in standard black, alongside 100 units of the 667B water rower for the hospitality and aesthetic segment. That combination covers heavy-commercial, performance, and quiet-use applications in one shipment, with two separate spare parts lists and one logistics channel.

For facility operators, the decision is simpler. The 670D carries a 200 kg rating, a three-year frame warranty, and a fold for storage. Request the specification sheet and a finished sample before issuing the purchase order.
