Like title says want to build fat tire mid drive hunting bike. Live and hunt in Wyoming so hilly rocky terrain a 20-40 mile range with just me and gear roughly 275lbs. total. Got the bike Elocony 26 inch godzilla fat tire bike. Now just need to figure the rest looked at the bafang stuff, bng, and lightning rod I'm open to any others. OK with more complicated builds needing fabrication . I'm thinking the gng 3000w kit but confused on batteries needed and cotroller programming. No specific budget in mind probably under 3k
