Welcome aboard harrumph,
My advice is test ride both the C5 and the G5 and if you cant decide which is better for you then get both
Search the threads here for break in,,,BTW these UCE machines are way better than my old Iron barrel.
Upkeep is minimal and easy.
The motors internals are built anvil tough according to master wrenches who have taken them apart.
BTW;
Everyone knows Chrome is the fastest color,,, less wind resistance
