Boar Explorer, The Ultimate Fat Tire E-Bike

BOAR EXPLORER is what we call the SUV of electric bikes. It hauls! Explorer has the capacity to handle heavy load. Best option for an avid hunter, fishermen or a tough outdoorsman who wants to take along a bundle of equipment.

NEW FEATURES = Bigger wheels, wider tires - smoother ride, New handle bar - more comfortable grip and seating position

"Today we are reviewing the Surface 604 Boar Explorer and let me just tell you right off the bat here that this is the champion of fat tire e-bikes. Not just because of the quality, and there’s a lot of that to be had here, but because at 4.5 inches wide, this is literally one of the fattest fat tire e-bikes we’ve tested to date.

The Surface 604 Boar Explorer excels at wet, soggy terrain. Swamps, grasslands, streams and brooks. If there’s standing water, the Boar Explorer wants to wade through it, and that’s where these absolutely massive tires really shine." Brent McCluskey — electrified reviews
