E-bikes continue to be the undisputed most revolutionary technology/energy/mobility/time-saving/health innovation of the 21st century so far, but since the primary competition spends $200 billion a year on advertising, it's still all word-of-mouth.
Pedal assist e-bikes. It’s real hot in Oklahoma and I ride with 1-3 kids. Riding a pedal-only bike for my daily trips is pleasant for 2 months out of the year, ebike extends that to essentially 12. It replaces a minimum of 6 trips per day.
