My Fat Bike experiment: can a bike be ridden through a sandy wildlife refuge said to be unsuitable for bike travel? The guy bought this for his wife at full retail in 2018 and she put a grand total of 10 miles on it

I paid $300. This is one of the 'good' Mongoose bikes, not a Wallymart Mongoose. Very nicely done aluminum frame with plenty of gusset plates and other reinforcements. It's all Shimano including 180mm hydraulic discs, 2x10, through-axle wheels, 4.5" Kenda tires, etc. This monster is going to take some getting used to for sure. No real problem going through the sand.
