I have a Rad Runner 2, or maybe 1, see the picture below, not sure, but I am sure is that all the little bumps and holes on the street are felt too much by my body. And yesterday I hit a bigger hole (but still pretty small) and I fell off. My knee hurts a bit and several scratches but fortunately I was at only 8-10 miles/h. The hole made my hands lose grip on the handle and fall. I need suspensions. What is the best fork you would suggest? I see online people mention about single and double crown forks, but I cannot really understand the practical difference. I also want a suspension on the seat. For that I found that the SR Subtour ( https://www.amazon.com/gp/product/B07FT931BP/ref=ox_sc_act_title_2?smid=A3POUIKOJR6CVV&psc=1) is the right one, it was sold on the Rad website in the past. So I guess I just need to find the right fork. Could you guide me with it? I will have a bike store assemble them.
