We’ve written before about the Wheelys — a crowd-funded chain of solar-powered coffee shops mounted on the back of bicycles. It seems each generation of the eco-friendly mini-cafés just gets better and better: the newest model, the Wheelys 4 Green Warrior, takes the chain’s sustainable focus further than ever before.

Like the models before, the Wheelys 4 manages to pack a full-service organic café onto the back of a bike — including all the equipment needed to make fresh coffee and a cooler for chilled beverages and snacks. However, where the older models were strictly solar-powered, this new version of the café is supplemented by a small windmill that can generate power even on overcast days.

If you’re interested in opening up your own Wheelys coffee franchise, act quick — the company is currently selling the carts on IndieGoGo, and they warn that their previous crowdfunding campaigns have all completely sold out. (In fact, after the first 24 hours, the $100,000 campaign is already fully funded.) It only takes $4,499 to open up your own Wheelys café, which the company claims most franchises can easily pay off within their first month.
