« on: May 07, 2026, 10:18:33 PM »I'm a little concerned about the battery capacity of the full wireless eGR. Gravel bikes tend to be ridden in more remote areas. I took my first gen eGR equipped gravel bike to the desert for a long trip and didn't charge it the whole time. That's with 2x 800mah 14500 batteries. Isn't the new eGR only 400mah with 1x battery? I hope it offers charging off a power bank or even a smartphone.
I have a Wheeltop group set. The battery needs charging every 2 months or so? 800mah.
I keep a shortened cable in my saddle bag that works using reverse charging on my phone.
