Hi, I believe in maintaining the mechanical aspects of all my bikes. I like the concept of the mid drive system, for when I build my own ebike. Do , or has anyone have information in regards to greasing or dry lubrication of the center drive? Is it ever required, or regularly needed? Is the mid drive unit a sealed component?.
I ride 365 in temperature range of 95°f to -40°F. ( 35C to -40C ) here in Central Canada. Any insight to this will help with my decision to build in near future. Thanks in advance.
