Congratulations with your bike, but what happened to the mudguards and bagage carrier ? I would have kept them on, because they really are part of the appearance of the bicycle, but maybe you dont have rain and dirty roads where you live. Nice that you managed to find a crankset that works with ...

I finished the bike, up leaving the rust and patina, but got the mechanicals working. I replaced the bottom bracket and found a crankset that I had to tap out as it was slightly too small for the crank axle. A couple pictures, including one of my 2014 Kona Paddy Wagon that I think is sort of a ...
