It has some sense at the end.
On derestricted e-bike, any one who has no experience can go max speed, loose control and kill someone.
On Road bike, usually pro riders with big experience, who knows how to control the bike can have enough power to keep going 45km/h. They have thousands of hours...
@RJUK thats for your car. There are cars with LFP battery, not being impacted with 100%. For LFP you do not care, it can be full all the time. But yes, ebikes are mostly li-ion. LFP batteries can (and should, according to Tesla) be charged to 100% regularly,
There are also uvex jeckyl hide and their latest revolt.
Revolt has ears protected even After face protector removal, but this must imact ventilation somehow.
Never used These two. I ride in Leatt enduro 4.0, as I found it best for me and it was in nice colors [emoji1787]
