Looking to build a bike because I can’t find what I’m looking for off the rack without it costing as much as a car. I live in Northern New England, I weigh 220, I want it for hunting and fishing in the remote back country with logging roads, atv trails, mountains etc.(fat tire? No/front/full suspension?) ideally with a honest range of over 30 miles would be desire. Maybe pull a cart with the gear or the days hunt? Was thinking dual batteries. YouTube has me spinning in circles with the information but thought it best to come to the experts.

thank you in advance for any guidance and please be kind to the new guy.
