This 2010 Stairmaster 4000K Home Gym is a well-used piece of fitness equipment, reflecting 5-10 years of consistent use. Its condition indicates visible wear from regular workouts, though it remains a functional option for home fitness enthusiasts. This listing does not include any accessories, so buyers will receive the base unit only, as provided by the seller’s details.

The Stairmaster 4000K is a robust cardio machine designed for effective lower-body workouts, simulating stair climbing to enhance endurance and strength. Known for its durability, this model offers adjustable resistance levels to cater to various fitness goals. Its compact design makes it suitable for home gym setups, providing a reliable option for users seeking a challenging workout.

Buyers should note that due to its age and usage history, the machine may show signs of cosmetic wear, such as scratches or faded components. However, the core functionality of the Stairmaster 4000K remains intact, offering a solid choice for those looking to add a proven piece of equipment to their fitness routine.

The best experience ever! I must admit, was skeptical at first, since we live in Rocklin (north of Sacramento) and the seller was in the San Francisco Bay Area, however I was extremely amazed by the professionalism of this company.

Nethaniel called me direct to congratulate me on the owner's bid acceptance, that same day. He also answered all my questions and was very knowledgeable, putting me at ease with the process of product testing (by their guys) prior to picking it up - as well as their policies in case something was not right with product.

Uriel then arranged with owner for pick-up, which was literally done the next day, and the following day I had my treadmill at my door. Professionally brought into my garage space and tested. Communicated with me prior to arrival, with correct ETA (actually coming an hour earlier - to beat the traffic).

Everything was fantastic all the way thru in the process - and I can't recommend this company's services and products. HIGHLY recommend using this company for your sports equipment.

This service is great. I had been looking at used Pelotons on facebook marketplace for a while, but was worried I would pay for one that wouldn’t work, and I was also worried that it would get damaged during transport. This service solved both those problems. I was able to bid on a bike and get a rate that was competitive with the rates on facebook marketplace. Of note, shipping is $150+ mileage, which I did not see clearly posted on their site. So just keep that in mind when making your bids.
I’m very happy that I have a like-new peloton for a good price and didn’t have to leave my home to get it.

Smooth selling experience! I’ve sold two pieces of equipment, and both experiences were easy and problem free. The drivers provided updates and were respectful on the property. Highly recommend!

Highly recommend! I recently sold my 2023 Tonal through them and the entire experience was great. The staff was fantastic from start to finish. Once a buyer was interested they facilitated the sale quickly and easily. They were able to schedule for pick-up within a few days with zero hiccups. They paid the agreed upon amount during pick up as soon as they verified the equipment was fully functioning. Oh, and did I mention I'm halfway across the country? These guys aren't joking when they say it's white glove service. I could not have asked for a better experience. If I ever need to sell a piece of equipment again, I'm only going through Try Common Place. Thanks guys!

Had the best experience with them!! Got such a good deal on the peloton bike. Came in great condition and was door to door service. Norman was amazing— he helped set up the bike completely, made sure it was working and balanced perfectly. Really took his time to make sure everything was good and even shared some Peloton tips. Could not recommend enough!!! If you’re looking to buy a bike or a treadmill for reasonable price definitely do through Commonplace!!! So easy and hassle free!

Absolutely great experience getting my Peloton Tread+!! Nethaniel walked me through the process - I was a little nervous about it making such a big purchase without testing the equipment myself. He reassured me my purchase was secure which was a huge relief. Uriel reached out within minutes of purchase and delivery was set up same day for the following week (over 300 miles away and totally reasonable). There was zero ghosting/back and forth/weird requests for bank info typically found on FB marketplace! Commonplace reduced the stress and worry that comes with buying used equipment with their inspection service and amazing delivery team. Norman made the long drive and was great in communicating his arrival! He had a courteous and efficient team who were experts in assembly and set up too. He also gave me a few tips on how to keep my Tread+ in top shape. He knows his Pelotons! I’m so pleased with this interaction. Thank you!

Uriel, Norman, Netaniel and their entire team did an excellent job with delivery and installation of our new (used) Tread+. Communication was great throughout the entire process, we are very satisfied!

Perfect—just as described! The Peloton was practically in mint condition, with only 25 rides confirmed by the serial number. The entire process was smooth and efficient. Delivery was right on time with excellent communication from scheduling through to arrival. The delivery team was extremely polite and professional, and setup went flawlessly. Had my first great ride this morning—thank you to everyone who made this happen!

The peloton bike arrives standard with clip in pedals.

The pedals can be replaced with flat pedals if you order them separately. 

Clipping into the pedals enables you to workout your hamstrings by pulling up on the pedal as well as your quads by pushing down. 

 

  • Gen 1: Oldest model; Peloton has discontinued class streaming on this version. Slower performance and outdated screen tech.

  • Gen 2: Still supported, but features slightly lower screen resolution and weaker audio compared to Gen 3.

  • Gen 3: Most current version of the original bike, with a sharper display, better sound, and faster performance.

  • Bike+: The flagship model, featuring a 23.8″ 360 degree rotating (swivel) screen (2.3″ larger), auto-follow resistance, and a premium 4-channel speaker system.

    Tip: if you’re looking to upgrade your bike with the swivel screen, consider checking out the pivot accessory we offer
