This simple but effective tool is especially perfect for indoor exercisers who are always on the go. An ultra-lightweight and compact portable exercise “bike,” Excy was designed with the busy exerciser in mind. You can use the simple setup to train your legs or arms anytime, anywhere. What’s more, it pairs with a mobile coaching platform featuring on-demand workouts and progress-tracking tools. Excy will officially launch on Kickstarter on October 21st, 2015 and the makers say the first systems will be ready to ship by November 2015.
