Anyone else with this issue??

Hello

I am researching e bikes, spend many hours looking at video reviews  and written ,
I am leaning toward a folding bike not so much for the frame folding but mostly for
The ability to fold down the handle bar , this will give me a desirable bunk height in
My medium roof Ford Transit van and just to wheel the bike in with the handle bar
Folded down.
The Rad expand Five folding bike has got some really good reviews and I really like
This bike, but I stumbled on some issues I read about and there is even a video that
Explains this in detail, the stem part below the fold part only has 1 screw that tightens
This to the fork steering tube? I looked at the close up pics on Rad website and it does
Indeed look very suspect , the part looks to made out of plastic and the threading
Is machined in to the part.
So the issue is the handle bar wont stay tight even when tighten to proper spec and in
Some cases be dangerous and some people have had crashes ??
One screw to torg down the stem to steering tube , should be two ? And also steel or aluminum
Stem part. This is just info from the great wide web so I dont know for sure?? Be nice to see a
Bike in person but I dont live close by any dealers , maybe some Rad Exspand Five owners on
Here can help shed some lite on this.

Thanks.
