If you get “shunted” from behind by an SUV, 3cm of expanded polystyrene foam is going to make FA difference to the outcome.

Bike helmets are designed for low speed crashes NOT involving vehicles.

Now I still wear one myself but I don’t fool myself that doing so brings me any protection from someone driving an SUV who thinks they’ll be late getting to a 24 supermarket if don’t just squeeze by me.

It’s like putting an oven glove on an egg and hitting it with a hammer.

Just incase anyone wonders why I wear a helmet when I think they’re as useless as “anti-volcano spray”, it’s because they make my head a more aerodynamic shape.

A quick look a Strava’s stats will show you that even weak club cyclists like me, living somewhere pretty flattish, can already cruise about at over 20mph pretty easily.

Pedal assist ebikes just expand that ability to a wider number of people.

Just look at the number of people who regularly crash in amateur crit races.

We generally survive non-vehicle related crashes at these speeds pretty well and people on ebikes will too.
