I enjoy riding all of my bikes. Sometimes the decision as to which bike to ride is made at the last minute. I can't afford (emotionally) to convert them all, and besides = wouldn't it change the handling characteristics?
The DeRosa wouldn't handle like a race bike.
The Mondia wouldn't be the superlightweight any more.
The lower gearing for the Harding would now be too low.
I fear the silky ride of the Merckx SLX wouldn't be so silky.
Extra pounds on the Calfee - unthinkable.
Titanium e-bike just sounds wrong.
And a custom lugged steel ebike sounds overly ostentatious.
Not for me.
But my big (older) brother is going to buy one - and if he rides, that's good, after all he's in his 70s, I'm just 66 1/2.
