|Single-speed systems||High ease of maintenance; Maximum reliability; Low price; The narrow range of applicability of such a drive.|
|Systems with external switching||Wide range of gear ratios; Relatively high efficiency; Ability to shift gears under load; Low weight; Good maintainability in field; The need for regular adjustment, inspection, lubrication and replacement of a number of components; Poor work in the absence of maintenance; Poor work in very dirty conditions; The presence of “forbidden” gear combinations.|
|Planetary bushing||Maintenance-free (including lubrication and replacement of parts) and owner’s skills; The ability to shift gears without pedaling; High reliability in utilitarian applications (dirt, rain, but low loads); High resource of chains and stars; Low efficiency; Relatively high price; Great weight; Low reliability at high loads; A narrow range of gear ratios for low-cost bushings; Not the possibility of repair in the field.
