The HyCycle isn’t the kind of thing you’d want to have to take through airport security — at least not in its present state. The electricity-generating electric bike prototype is bit of a mess of wires and blinking boards at the moment, plus a battery that looks an awful lot like a block of C4. All are attached to one of its creators’ rust-colored Schwinn road bike. The bicycle is a project of a group of┬áNortheastern┬ástudents, an attempt to build a cheaper electric bicycle — one that can be offered as a do-it-yourself kit that users can snap to their existing bike frame.
