Back in the 70's loads of us had 'field bikes', generally mopeds or small capacity motorbikes that we rode around farm lanes or the local quarry*.
These high powered e-bikes just seem a new version of this, no doubt 'older folks' were just as pished off by us back then.
* even Allan Millyard did it but being him he grafted a Mini 850 engine into a BSA Bantam frame..............by his own account it was lethal.
