I purchased a genze 100 series in early spring 2018. I was riding 20 to 35 miles 4 to 5 times a week for the first few months until my job put me on the road. Now I'm back and just purchased a bright eyes light so I can ride each evening. I'm hoping to do some multi day rides after getting some pointers from some of you experienced ebikers. I live in Sacramento and would like to do an extended ride maybe in the Napa valley.
