Thanks everyone for the responses,

I believe it is the battery connection and I'm trying to get a new one with Rad Power. I got ahold of someone but they've sent the wrong cradle so I guess I'm trying again.

I don't know if anyone's interested but I removed the current battery connector and attached a photo showing the build quality of the thing

Hi all,

I have a 2019 Rad City that's started having a persistent problem. When powered on the display turns on briefly, shows almost no battery life, then turns off. This happens despite a full battery. I've now tried two separate batteries, including a brand new one I borrowed, a new display, and a new controller. I've checked every cable connection and I had a local e-bike shop check as well.

I just learned that if I manually connect the battery terminals (just the two positive and negative, not the three small poles) to the bike with alligator clips it powers on just fines and the motor runs.

Has anyone seen this before? Anyone have any idea what could be the issue? I don't know what the three small poles on the battery connector do so I don't know if they're related, or if it's just a bad connector or what. Visibly the connector looks fine.

Any help greatly appreciated
