I am going to get some but until I do I been using a clip on telescopic guard called the flinger and a similar fender on the front,they work but aren’t as convenient when folding up etc...
As for the carrier I have a kanga/vario rack which I use on the front with the Rixen & Kaul frame adapter and that works very well,I also have the match pack which I use on it when the racks on my e bike. I’d of gotten the vello rack had the shipping not been so pricey. There are some good alternatives but at the end of the day their fenders are the best looking and seem to work best. If your in the UK bikefix have a very limited supply of spares/accessories so I’d imagine other countries will have outlets that have them too.
Good luck
