Treadmills must be oiled approximately every 3-6 months, depending on usage, using silicone-based anti-friction lubricant. This model is self-lubricating but you must ensure to check the level of oil in the oil reservoir. Instructions on the self lubrication are in the Manual provided and on our website. We provide the oil when you purchase the treadmill. Failure to keep sufficient oil in the oil reservoir may result in the loss of the Warranty Cover.
All treadmills are pre-oiled but we recommend adding oil to the reservoir before usage.

  1. Brian Spring

    Got this treadmill today. Had it up and going in less than 10 minutes. I have been a gym goer all of my life and this is gym quality. Solid, looks good and has everything I need. Loving the colour screen and having the player meant I could watch Netflix. Highly reommend.

  2. Brian Sheridan

    My friend bought one and recommended it to me. This is a high quality item and a nice looking machine. The interface is like using tablet and I was able to set up different profiles for myself, my wife and the kids. It has voice prompts as well which is a nice feature. Great value for money.

  3. Andy Lordan

    Bought two for my gym. Researched around for a few weeks and nothing of this quality for the price. Sound on the phone and sent me a business invoice. The self oiling is a lovely little feature. Makes them low maintenance. Very quiet motors as well.

  4. Darren Price

    Delivery is prompt and tracked, which is good. Over the past few months, I have placed a number of orders and keep returning. Extremely well-built, industrial-style, and highly functional treadmill. I’ll be returning to Inthemarket. ie to order more.

  5. Darren Price

    Found you on Google and delighted I did. Have to support Irish retailers. Delivery is prompt and tracked, which is good. Over the past few months I have now placed a number of orders and keep returning. Extremely well built and highly functional treadmill.

  6. Bernadette Baker

    I am extremely happy with my treadmill. Communication was very quick regarding all aspects of stock/delivery. More importantly, the treadmill is of very good quality and excellent value for money.

  7. Jess Keegan

    I am absolutely thrilled with my C-66 Commercial treadmill. The compact design allows me to easily store it when not in use and the powerful motor and wide variety of workouts keep me challenged and motivated. I highly recommend this treadmill to anyone looking for a top-of-the-line fitness machine.

  8. Moll Gallagher

    I’ve been using this treadmill for about 3 months now and it’s been great. The motor is powerful and the belt is wide, making for a comfortable run. The built-in programs are also a nice feature. Overall, I’m very happy with my purchase.

  9. Marie

    Couldn’t be better. Looks great and the features on it are top class for the price. Have had this for nearly six months and it is the best thing I’ve ever bought. Very comfortable to use and I’ve managed to shed the weight. Super.

  10. Mary

    This thread mill has so many features. We keep finding new stuff on the console. You can watch netflix and my husband likes the videos of tunning through the forrest and on the beach. It has a very comfortable running area which is important cos my knees are not great. The office staff were lovely and we had it delivered to our door and paid to get it made up. Bargain.

  11. Therese Flavin

    It is the job for using at home. Folds up easily and has wheels so we can pop it into the corner of the spare room when done. Has everything you need on it and the people here are lovely to deal with.

  12. Claire and Thomas

    We wanted to develop our home gym and visited some stores and have been online a lot. Been watching inthemarket for a while and their products looked great and teh reviews were very good too. My wife called and spoke to a customer care person who went through all the options with her. We had some follow up email questions and they came back quickly. The treadmill arrived quick and the driver was lovely. The C 66 is a gorgeous tread mill. Functions all over the place and confortable and easy for us to use. Thank you very much.

  13. Mairead Quirke

    Bought this with cross trainer. Both are exceptional but this is the ebst treadmill i have ever seen. For the price, it is so comfortable. Customer lady on the phone was so lovely and we had it in three days.

  14. Anonymous
