Element Hotels introduced stationary bikes with pedal-powered generators into the fitness centers of all 10 of its locations. The power-generating bikes allow guests to charge their tablet devices or cell phones during their workout.

Element Pedal Power Station"Not only do our pedal-powered bikes add an element of fun to a workout, but they also encourage our guests to think creatively about sourcing the energy we all depend on to fuel our daily lives," Brian McGuinness, senior vice president of specialty select brands for Starwood, said in a press release.

The power-generating bikes are just the latest in a series of design features and amenities that enhance the well-being of guests. Element says it was the only major hotel brand to pursue LEED certification in 2008 for its high-performance buildings across the brand.

The eco-conscious brand introduced the bikes at the spring 2012 launch of its Element Miami International Airport hotel, when the company's CEO, Frits van Paasschen, joined associates in a cycling effort that generated enough electricity to lend power to flat-screen plasma monitors and laptops for a virtual ribbon-cutting presentation.
