Cargo bikes (and trikes) are great for hauling cargo and/or kids, and folding electric bikes with less powerful motors and skinny tires are ideal for urban commuters. But if your summer plans include hitting the trail, an electric mountain bike with a powerful motor and fat tires is the only choice. Right now, Walmart has a very popular example of the latter on sale with a mountain of a discount.The Gocio 4.0 Fat Tire Electric Bike is on sale for $550 at Walmart, 35% off its normal $840 price tag. This deal is good on the black colorway; a red option is on sale for $50 more while the white version is sadly sold out, a likely indicator that this e-bike will sell quickly with this discount.Gocio 4.0 Fat Tire Electric Bike, $550 (was $840) at WalmartGocio 4.0 Fat Tire Electric Bike, $550 (was $840) at WalmartCheck PriceThe promise of a fat tire e-bike is completely fulfilled by this model, which has anti-slip tires that are 4 inches wide and 26 inches in diameter. They pair nicely with the high-strength carbon steel suspension fork for a smooth ride even over bumpy terrain. If that terrain is also a steep slope, the 500W motor — that can peak at 1,000 watts — is powerful enough to conquer 30% grades and reach speeds up to 22 mph. The lightweight aluminium frame helps keep operations efficient, and the 13Ah battery (that's UL2849 certified and BMS protected for safety) has a range of 30 to 50 miles. Rounding things out are pretty standard but necessary features like an intelligent LCD display, five modes, seven gears, and a headlight.AdvertisementAdvertisementRelated: Walmart Has a $2,000 Electric Bike on Sale for 56% OffOne shopper wrote that this "big wheeled bike is a beast," a powerful machine that's "a whole new experience" even compared to other electric bikes.
