Copenhagen Wheel

Gosh, yesterday was a bonanza!
In addition to the Frenchies arrival in the morning, the Copenhagen Wheel (that I ordered 14 months ago) arrived yesterday afternoon.
I charged it up this morning then installed it this afternoon on Kathy's mountain bike.
We both can get to know this gizmo using her mountain bike.
We will switch the wheel around on four of our bikes.
My first impressions in a word... marvelous!
