Lovers of Brutalist design: boy, have we got something for you! This is the BikeBlock 2.0, a concrete cube specially designed for bike parking. As the “2.0” in its name might suggest, its German creators URBANATURE have changed things up since the first time around, namely adding waffle-structure inside the slot for extra stability. The block is suitable for all bikes up to 14 kilograms and almost all tyre sizes. Weighing in at 18 kilograms a pop, you’d want to be pretty sure that the first place you put it is the final place you put it.
