1. Imiterere: Urunigi rwinyo rugizwe nibisahani, urunigi, nibindi. Ifite amenyo kandi irashobora gutuma leta igenda neza kandi neza.Urunigi ruzunguruka rugizwe nizunguruka, isahani yimbere ninyuma, ibiti bya pin, nibindi. Ibizunguruka ni silinderi ifite diameter ntoya, ishobora kugabanya neza kwambara urunigi nibikoresho.
2. Uburyo bwo kohereza: Uburyo bwo guhererekanya urunigi rwinyo ni ugufatanya gufatanye, ahantu ho guhurira hagati yisahani yumunyururu na spocket ni nto, kandi coefficente yo guterana ni nini cyane, bityo uburyo bwo kohereza urunigi rwinyo ni buke.Uburyo bwo guhererekanya urunigi ruzunguruka, ahantu ho guhurira hagati ya roller na spocket nini, kandi coefficient de friction ni nto, bityo uburyo bwo guhererekanya urunigi ruri hejuru.
3. Ibiranga: Urunigi rwinyo rufite urusaku ruke, kwizerwa cyane no kugenda neza.Iminyururu ya roller mubisanzwe yerekeza kumurongo wuzuye kugirango uhindurwe mukanya gato, ubereye amashanyarazi mato.
Kurangiza, iminyururu yinyo hamwe nuruhererekane rwiminyururu biratandukanye muburyo, uburyo bwo kohereza no kubiranga.
