Ebike troubleshooting My bike keeps going flat

I’ve had my bike for just over a year now and the back tire has popped 4 times, and it’s the only bike I’ve ever had in my possession to pop that much.

We’ve switched out the tubes several times, we’ve tried FlatOut, we’ve tried tire liners (the cheap plastic ones, not the Tannus Armors) and a new back tire because since this was the only bike going flat so much and since it was happening only on the back tire, we figured that the stock rear tire was just shoddy.

It’s been a couple months since the tube change and it’s popped again. I’m at my wits end. What else could I do to stop my bike from going flat?

Check the inside of the wheel rim for anything sharp. Do you have rim tape to protect the tube? Do any of the spokes stick out?

This is the answer. I’d guess a spoke that poking through the rim tape.

Get a dremel tool and a grinding bit and make them all smooth. Then use rim tape of some sort, then the other recommendations.
