Here's a product we've been waiting on for years. Carrying around a bike helmet has always been a pain, particularly if you're using a Dublin bike or beeper bike to get around. Where do you stash your helmet all day long? As a result many of us don't wear a helmet at all. The Plixi helmet, designed in France, folds up to a third the size of a full helmet without compromising on safety, and makes it much easier to be safer on our bikes. Like an old fashioned transformer it takes three moves to assemble it for use and feels really sturdy in the hand. As comfortable as a standard helmet, the Plixi comes with extra pads in the box to adjust the size to your head. It's also suitable for rollerblading, skateboarding or riding one of them new-fangled e-scooters you see people going about on.  There's also a range of changeable covers and visors to accessorize your helmet available.  What's it made of?ABS & expanded polystyrene.  How does it come?In a box, 21 x 11 x 16 cm when folded.
