Climbing up the Historic Highway to Crown Point yesterday, I noticed two bikes behind about halfway up, and was a little surprised they didn't pass me. At 210 lbs in my 7th decade I'm no climber, and typically get passed when other cyclists are going up. On the steepest ramps they fell back quite a bit. Unusual. I was taking a pic at the overlook when they arrived, and I was shocked to see two ebikes. Unless their batteries were dead or they had the assist turned down, I don't see how they were getting much of a workout.
Even on an overcast day, the gorge is stunning no matter how you get there.
