Unless you’re in Arctic or sub Arctic winter conditions, I cannot imagine needing heated gloves if you gear up properly. Save for maybe a medical condition that causes poor circulation.
Presume you already have good hand/thumb warmers. Glove liners are key in very cold temps. Thin wool, silk or the reflective ones. If quality insulated gloves with liners aren’t enough with hand warmers, put some gauntlets on your handlebars. Losing the windchill is like riding in 20 deg warmer temps.
I rode for years on my YZ450 Snowbike, no hand warmers (warmer temps in the cascades compared to other places). And with full gauntlets over the bars, I could ride most days with just light gloves.
I always seem to get a couple pairs of gloves wet on a good day of riding. So that wouldn’t jive with electric gloves either.
Mittens are another option.
And my second warmest gloves (besides some big leather goretex Cabelas gloves) are actually a pair of furry lined rubber gloves. Idk why but they are as warm as anything I’ve used save for mittens and also grippy, not bulky, and cheap!
Last resort. Hand warmers. Unless you’re riding 50 days a year, hand warmers are cheap all day heat.
Just throwing out other options.
