Pah, I could tell you Johnny come lately ebikers a thing or two about cheating remarks.
When I started ebiking in 2010 such remarks were relatively common, including a handful that were genuinely nasty.
Equally, I had a couple of compliments about my cycling prowess from roadies who didn't realise my steady, long climb or brisk pace on the flat was electrically assisted.
At the time, I was also new to cycling, so the apparent obsession of some cyclists about what the other bloke was doing baffled me.
Adverse remarks all but ceased three or four years ago when ebikes became more mainstream.
These days, it's more genuine interest, and even a few compliments when I'm on my Riese and Muller Charger with its Rohloff hub and other fancy bike bits.
