New member here; looks like some great info. I have a RadRunner 3 plus; so far so good. I am thinking of installing a lower rise handlebar for a slightly better lean for my back; bending forward some is more comfortable than sitting straight up. I found what looks like a perfect replacement to use with existing stem and all the accessories. I'm wondering if anyone else has done this kind of a mod and how difficult was it? Here's a link the the handlebars that seem to be an exact swap with about a 4" drop in the rise. 31.8mm to fit existing stem and 22.5 mm for all the accessories. Thanks

I replaced the handlebars with the lower ones I found online. The handlebars were an exact match other than the rise. It's about 2" lower and feels better when I ride. The fit seems to be closer to my regular bike. More ride time will tell.
