I was able to purchase the Abus Wheel Lock 5650L NR from RadPowerBikes.ca but the ABUS Adaptor Chain had been continually out of stock. So, I ordered it from https://www.bikeinn.com/ December 3rd and it arrived today. I will use it to lock the front wheel to the Abus Wheel Lock on the rear wheel. Also picked up a handlebar water bottle holder. With the bike seat lock https://www.radowners.com/index.php?topic=1436.0 , I believe I have all the security I can muster for a bike covered.
