I charge my ebike once every couple weeks. Granted I ride my non ebike most of the time, but with a daily commute of 4 miles, I can ride for 8 days straight without needing to plug it in. Not a big deterrent at all.

Helmet sits in the basket or hangs off the bars, takes ten second to put on so also not a deterrent.

The real deterrent is thinking “goddamn it’s 27 degrees out and my gloves are getting frayed my fingers are going to be cold”.
