The Rollin' Bike by Moritz Menacher is lightweight and functional.
The bike is designed from a single sheet of laser-cut aluminum, and is both lightweight and stylish. The design is geometrical, and would be perfect for those looking for a little extra speed on the streets. The lightweight, chic design may worry some about theft, but the bicycle also comes with an integrated, easy-to-use lock.
Many individuals are moving towards more eco-friendly modes of transportation, but larger bikes can be a hassle to carry around. City streets can become crowded, and it's occasionally necessary to carry cycles. Designs such as this one by Menacher are perfect for combating this problem, as a lightweight frame makes for an easy lift.
