Bern are an American helmet maker who started in snow and skate protection and moved into cycling, which shows in the shape of their commuter range: fuller coverage and a squarer profile than a road helmet. The Hudson MIPS listed here is the model that matters most to e-bike riders, because Bern certify it to NTA 8776 as well as EN 1078. NTA 8776 is the Dutch speed-pedelec standard, tested at a higher impact speed than an ordinary cycle helmet, and very few helmets sold in the UK carry it. Worth knowing that it still is not a motorcycle helmet, so it does not cover you on a bike that exceeds the EAPC limits.
