Beschreibung
Zusammenfassung:	A bicycle drive system includes a front face gear, a rear face gear, a drive shaft, and a front roller-toothed gear assembly coupled to the first end of the drive shaft, and a rear roller-toothed gear assembly coupled to the second end of the drive shaft. Both the front roller-toothed gear assembly and the rear roller-toothed gear assembly include one or more roller elements. The roller-toothed gear assemblies are advantageous in ensuring the bicycle drive system is highly efficient, and is only minimally or not at all affected by dirt, water, contaminants, or other foreign matter typically experienced in un-clean riding conditions.
