This isn’t trolling, this is real concern.
I’ve just had a look at what legally defines an e-bike and this is what I found
EAPC requirements
The requirements are:
the bike must have pedals that can be used to propel it
the electric motor shouldn’t be able to propel the bike when it’s travelling more than 15.5mph
the motor shouldn’t have a maximum power output of more than 250 watts
It must also display one item from each of the following:
the power output or manufacturer of the motor
the battery’s voltage or maximum speed of the bike
So as long as it ‘can’ be pedaled then it can also have a throttle as well. So if you put a sticker on the motor/battery stating ‘250 watts’ then who’s going to question it?
