I have had a couple issues with my Rad Runner. The first issue I wad riding on a damp tar path and I lost all power to my bike. The display was still on but not working. I removed the battery/replaced and the bike started working again. The second issue has happened a couple times in the last week. Dry riding on the same tar path and I lose pedal assist. The display works and it displays the speedometer with no pedal assist. I use the handle bar switch to turn the bike off and on again and again. Today I thought I was going to have to walk the bike back home. I have reached out to Rad support without much luck. The bike has about 275 miles on it as of today. Any help would be greatly appreciated.
