Yah! It's kind of a sad time for everyone.  The shipping and availability of replacement parts has been a problem for the customer and RAD.  I can see where RAD can have trouble getting parts (pandemic etc.) but on the other hand if they can get and build ebikes to sell why can't they get parts as they have to have parts to build ebikes.  Hope everything works out.  Keep us informed.

Good luck on getting the motor Radicali. I've been waiting seven(7) months to get a replacement for my Rad City 5 Plus.  Still Waiting.   
My Rad City runs Ok but I can't use the throttle and Pedal together. Crazy but I still like the bike even though I had to change my way of riding it 1500 miles.  I also have a 2018 Rad City Step Thru.

This works great and can be used for other storage...... $25.00

Schwalbe Big Bens are made for ebikes.  I've used them for years and they are very quiet road tires, but work for off road too.

If you are an old road cyclist I would buy the RadCity 5 Plus Step-Thru.  It is a lot easier to mount and dismount and it is a great road bike.  For the road to me it is a better choice than the the Rad Rover plus 6.  I'm and 85 year old rider and I own two Rad City bikes.  One 2018 with over 10,000 miles and a new one with 1100 miles.

The best way for me is to use a white china marker.  This way if you change your mind about your setting (and who doesn't) you can just wipe it off and remark.
