Frequently Asked Questions (FAQ)

How high does the ceiling need to be?

The unit is approximately 229 cm tall. Be sure to allow for additional headroom for the user—we’d be happy to check this based on your ceiling height.

How does the RX4400 differ from the RX4405?

The RX4400 is the larger model, measuring 229 cm in height and equipped with 4 transport casters; the RX4405 is more compact at 152 cm in height and can be configured at 50° or 60°. Both are self-propelled.

How does resistance work without weights?

About the progressive magnetic resistance with DSS technology: The faster and harder you pull, the higher the resistance—automatically, without any levers or clip-on weights. According to the manufacturer, to switch to strength mode, simply change the direction of pull.

Does the device require power?

No. The magnetoresistive sensor operates without a power connection; only the LCD display runs on 2 AA batteries.

Why "Make an Offer" instead of "Buy It Now"?

Ropeflex-The devices are shipped from the U.S.; shipping, customs duties, and delivery time depend on the configuration and destination. You will therefore receive a binding, fixed-price quote with no open items.

Is Kraftathlet an authorized dealer?

Yes. We source Ropeflex directly and supply genuine products with a manufacturer's warranty. You will receive a written quote detailing the price, shipping costs, and delivery date.

Ropeflex-These devices are exercise equipment, not medical devices. All technical specifications are provided by the manufacturer; measurements have been converted from inches and rounded. If you have any health concerns or are undergoing treatment, consult your doctor or therapist before exercising.

Frequently Asked Questions

Answers Before the Offer

Delivery, payment, financing, and service—these are the issues that should be clarified before making an investment decision.

We ship throughout the European Union. Our focus is on the DACH region—Germany, Austria, and Switzerland—because we have established our own freight forwarding, installation, and service partners there and can make binding delivery commitments.

For deliveries to other EU countries, we calculate shipping and installation costs on a project-by-project basis. Please let us know the delivery location, floor level, and access conditions—both of these details, along with the price, will be included in your quote.

If the item is in stock, please allow 7–10 business days from the date we receive your payment.

For custom models, specific color and upholstery requests, or complete studio setups, the delivery time may be longer. The binding delivery window is listed in your order confirmation—as a commitment, not an estimate.

We'll contact you before we process a payment.

You'll be given a realistic delivery date, and you can then decide for yourself whether to wait, switch to an available model, or cancel your order. We do not accept payment for items for which we cannot meet the delivery date.

The following payment methods are available at checkout:

  • Credit and debit cards — Visa, Mastercard, American Express, Maestro, and UnionPay.
  • Digital Wallets — Apple Pay, Google Pay, and Shop Pay.
  • Local payment methods in Europe — Bancontact (Belgium), iDEAL and Wero (Netherlands), Przelewy24 (Poland), and MobilePay.
  • Payment by bank transfer in advance — the standard for larger orders and studio equipment.
  • Payment in installments via PayPal — for eligible customers.
  • Hire purchase and leasing through our financing partner.

For larger orders, we recommend bank transfers or financing, as credit card and digital wallet limits are often lower than the order amount. Additional payment methods, including installment plans and BNPL options, are currently in development.

Yes. With hire purchase or leasing, you spread out the investment over monthly payments instead of paying it all at once. With hire purchase, the device becomes your property at the end of the term.

Upon request, we'll include the terms directly in the quote so you can see the purchase price and monthly payment side by side. You'll find all the details and a calculator under " Leasing & Rent-to-Own."

Phone: Monday through Friday, 9:00 a.m.–5:00 p.m. (CET) at 0800 000 8929 — toll-free from Germany.

WhatsApp: You can also reach us outside of business hours at +43 665 67105401.

Email: beratung@kraftathlet.de for quotes and advice; customersuccess@kraftathlet.de for service and post-purchase inquiries.

You may return your order within 30 days of receipt. To do so, the merchandise must be unused and in its original packaging—for commercial equipment, this is a prerequisite for it to be resalable.

Please notify us in advance if you wish to return an item so that we can arrange for its return. The full terms and conditions are outlined in our Return Policy.

Yes. Upon request, we’ll handle transportation to the installation site—including transport within the building, setup, functional testing, training for your team, and disposal of packaging materials—even in buildings without a ramp or freight elevator.

Tell us the floor, door width, and elevator situation, and we'll include the location and price in the quote instead of it being a surprise on delivery day.

The vast majority of our clients are studios, medical practices, hotels, and institutions. They receive a proper invoice showing the applicable sales tax.

For intra-Community deliveries to businesses with a valid, verifiable VAT ID number, we bill using the reverse-charge procedure. We assist public contracting authorities by providing the compliance and procurement documents required internally.

Can't find your question here?

Send us a floor plan or room measurements and tell us what you plan to do in that space. You'll receive an estimate before we discuss equipment.
