One of the tweaks I have been working on for the Borealis V3
This is the rolled edge that stiffenes the velomobile and is a handy spot to grap for getting in and out. It also provides a spot for the door to land on keeping it nice and flush with the rest of the parts. We lay up this part up in a separate mould and than bond it to the base. Used some graphite and basalt in the part with a bit of glass. Its nice and stiff but not too heavy. The extra bit of stiffeness this adds means I can take some material out of the side of the base. This will make the layup a bit quicker to do as there will be less pieces of kevlar to cut.
