When it comes to features, Endurance TF3i delivers as expected. The motor that is running the whole thing is a 2.2 hp unit with peak power maxed at 6.6 hp. What this translates to are speeds up to 10 mph. Additionally, there is motorized incline with levels ranging up to 12%. Looking at the features of the control module, things are fairly simple. Maybe even too simple. Instead of going with a single LCD display solution, Endurance TF3i went with four different ones. Each display is tasked with providing specific stats while you can track your overall progress by looking at a running circuit display at the top. This one is made out of small LEDs but definitely helps with visualizing how much you have left. Last but not least, you have a number of preset workout programs to choose from. Overall, it’s fair to say that Endurance TF3i is a niche machine.
