I bought a ride1up 500 earlier this year and really like it. However, I miss my younger days of going on the trails and the 500, while fine on forest roads and really smooth trails, feels top heavy and insecure on all but the easiest trails. I'm 76 and in pretty good shape and am wondering if something like the Lectric XP (20x4 inch tires) or the Espin Nero (26x4 inch tires) might get me back on the easy trails. As an aside, I did ride a RadRover last year and it just felt to bulky for trails at my age. Suggestions?
