Everyone has a right to their opinion. I understand peoples concerns even if I don't agree with them.
Once I had a power failure, and pedaled 8 miles home. Luckily my bike has a 9 speed pedal gearbox, and the bottom 3 gears have beach cruiser like gearing.At least you could still pedal that thing when the battery is dry.
IMO, as long as it's got pedals and can be propelled by pedaling, and two wheels; it's a bike.
Regardless if it's a fully faired, record setting recumbent or a10kw motored ebike.
If it's got three wheels, it's a trike.
