What is this on my RadRover 6 +?

There are two welded squares on my bike that I can?t figure out. They have three treaded holes on the bottom. I don?t see anything on the web site that might use them.

Just a guess, but I'm betting those are for the factory frame-welding jigs to align everything properly and not intended for use after assembly is complete.

Could be I?ve sent pics to Rad. I?ll post their response. They have become so slow though.

My guess would be a "frame lock" or "wheel lock". Most of the city bikes in Scandinavia have these locks.
Though I couldn't find a 4" version of this lock, but I'm sure they're out there.

You ever hear back from RAD? I'm curios to know what they are.

No called and sent messages. Strange because they?ve always been really quick to respond before. Hope I don?t have a problem if customer service has truly gone bad.
