With the racer bars the bike becomes more flexible. I love it. More space for the legs and a good place for the mirror. It didnt work to fix it on the helmet. Almost got me under a car :- (
It took me some time to figure out how to put a rag on. And to realize, its not for heavy duty. The backfork istnt made for load like that. But how simple it is to just attach some backpacks to the sadlepost! There is sooo much space under neath the seat! And with a strap it sits firm. What a wonderful bike!
