Took my 30s Shelby Gambles Eagle out for first system check ride, a few miles around the neighborhood, and everything worked perfectly after a rear brake adjustment. The bumpy ride over many speed bumps was surprisingly s. Tomorrow I'll take it for a long ride with a big battery. Specs on the bike include 750 W Bafang mid drive, SA 3 speed with 70mm drum and adapted J.C. Higgins shifter, Shimano 6000 front dyne hub with band brake, and modern aluminum wheels. I got the bike with no wheels, a 50s Schwinn crank, mismatched 26 inch fenders, average period gooseneck, 40s bars and a 40s seat.
