    easy install (on a spinner s3) I bought it mainly for the cadence and timer functions. makes it easier to follow utube classes when they give you target cadence numbers.

    So far it's performing as advertised. I'm just looking to keep a record for myself each time i spin. I am not training for the Olympics! Be sure to log results prior to units auto shutoff feature or you will lose your current workout. Also while installing wheel sensor I had to be creative and alter the simple install instructions so I could get the required distance between wheel and sensor. I purchased extra magnets ($2.99 for set of 6) from a big box home improvement store and was able to stack them to achieve and maintain the distance required. As stated earlier I am quite satisfied as the unit is all I need. For the complainers or those training for the Olympics you may need to spend way more to get many more features and to be happy!

    This is an excellent little computer! It has made a world of difference in my home spin sessions. I'm not the least bit mechanically inclined and was still able to install it all by myself in a matter of minutes. I'm so very glad I decided to buy this one instead of the Cateye I had been considering.

    I purchased the Spinning Bio Wireless computer & attached it to an old Schwinn bike. I had no problems attaching the sensor and sensor reader to the front fly wheel and bike frame. The piece that mounts to the handle bar so you can slide the monitor on and off of it isn't a perfect fit since it isn't a Spinning bike but was able to attach it firmly with zip ties. Looks fine and is totally secure. Great little computer.

    This is one great little computer. I'm not mechanically inclined and I still installed it on my spin bike all by myself. Easy to install and easy to operate. This is my kind of computer! My spin bike is not one of the Spinner brand. I have a Tuffstuff 350 SB and it still was easy to install and works like a charm! Definitely a good buy.

    I just bought the Spinning Bio computer for my Pro Form 290 SPX. It works great. I tweaked the install since I had to mount the transmitter on the chain guard. But all in all well worth the investment, I am getting a more consistent workout and can gauge my progress during my Spinervals rides

    The Best Computer system for a spinning bike! I had tried the Cateye brand, it sadly did not deliver. This Bio Wireless by Mad Dogg, was absolutely the easiest and easiest installation, literally took me lessless than five minutes.I have never had such an easier time with installing anything in my life! I could buy this again and again if I ever need to. Love all of their products. They have always been superb on quality, satisfaction and customer service and reliability. Thank You to Everyone for the great products that you build and supply for all of wanting to make exercise part of our daily lives. Thanks again for all you do. Angela Dunn
