Gary, use diversion. Set up some solar panels, charge your bike with the sun, and make, the crowd go ohh ahh! Tesla did similar demonstrations, Edison did too.
Show them how you use this to run the business, how much you enjoy it, focus on the positives. Get some video of some exhausted, and disorientated riders. Point at the dangers of rider exhaustion. Point out how much more alert the ebike rider is cooled by the wind on a hot summer day and how we can wear safer helmets and body gear, because we do not get too hot pedaling, and require flimsy head wear for air flow. Turn up with a motor bike helmet and ask, WHO IS SAFER NOW? Show them how much more balance an Ebike has with out peddling, show them how slow the bike can go and compete with someone peddling,
I bet my ebike balances and can move slower using the throttle and motor with out the rider losing control than someone peddling slowly shifting their weight.
Then distract them to the damage oil has done and the importance that this industry is not extinguished by suspicious, and intimidatingly limiting regulations.
The ebike is sleep, demand and deliver, compared to the the alternative ICE, No heat wasted, no noise, so we are not hooning, waking up the neighbours with our monster machines. It's totally inapropriate to regulate small to medium sized, all the reasons why we regulate motor vehicles do not apply to Ebikes what-so-ever.
