You're going to need a beefy motor and a lot of battery. 25 mph with fat tires on pure throttle is around 750-1000W, so ideally you want a 1000-1500W motor. You're looking at about 24 min each way, 48min total. Since you don't want to regularly run the battery below 20%, and the cold will take another 10% range hit. (800W*0.8hr)/.7 = 915Whr minimum battery size.
Ideally, you want a 1500W motor with a 1200Whr battery.
Something like a Juiced Scrambler or Scorpion are probably the style you're looking for.
