Not exactly eBike related, but I was riding. I heard two gas motor somethings coming up quickly behind me while I was riding a multiuser paved trail about 2:00pm yesterday. As the first pulls up next to me, I see it's a dirt bike motorcycle and the passenger slaps me on my back just above the waist on my right side. The second dirt bike comes up and the passenger slaps me in the back of the head on my helmet. They speed off, laughing their heads off. Luckily I maintain control, stop, and call 911. Three police vehicles show up and they search my neighborhood with no luck. I was within 1 1/4 miles of home. The officers took my picture and the red hand shaped mark on my back. Just shook me to my bones! Could have been a baseball bat, knife, or worse! The mark is lighter color on my back today, but sure it will turn into a bruise. Peoria, IL ranks really high in the United States for crime per capita, now it came to me. Ruined my day and probably will be paranoid for a while. Damned hoodlum teenagers!
