Basic the ebikes are 60% the effort 500% more fun and distance over a regular bike.
We live near a rail trail ,Use to load the bikes on a rack to drive to the trail due to the hills , now we just ride to and from the trail. Local trail has become boring so we have driven 100 miles to different trails.
Helmets we picked up Sena R1 , they have blue tooth and we can talk to each other up to about a 1/4 mile or listen to music.
Most brands have an Facebook page go the ask first hand opinion, I made a spreadsheet of features and prices and narrow down to my wants i.e battery size, hydraulic brakes ,bang for the buck and fitment.
