Brisbane Installation Offer

We have stock of this item in our Brisbane depot, and can arrange a professional installer to bring the machine out to your house at an agreed time to assemble it and give you a quick overview of operation. Simply select the "Assembly" option above to include this (it's in the box immediately under the price).

Conditions apply;

  1. Only applies to the greater Brisbane area, including Logan and Ipswich - if you live on the outskirts, please check with us first.
  2. The installers we use are professional, insured, independent Fitness Equipment Installers. They will contact you soon after you place your order to confirm installation, but the time and day will need to suit both of you. They only visit certain parts of the city on certain days, so thanks for your cooperation with this.
  3. Only one person comes to install, and as such, they cannot install in locations with more than 3 steps. If you need the machine moved up stairs, or your house is difficult to access, please mention this to the installer, and an extra charge may apply, payable directly to them on the day.
  4. There is a $25 rubbish removal charge if this is required, payable directly to the installer on the day.

Naturally, customers in other towns and cities are welcome to buy this machine, however you will have to assemble yourself, or contact an installer directly.

    Fitness while in Lockdown

    Posted by Ruby on 28th Oct 2020

    Needed an exercise bike to maintain fitness for work as gyms are closed. This bike has numerous levels to use and are built into the computer, a comfortable seat for both men and women. My partner and I both use the exercise bike. It suits tall people as we are 5ft 8 and 6ft 2. The bike is really quiet to use, feels sturdy when we ride and it is fairly easy to put together.
