The Surface 604 Boar Explorer is an excellent fat bike eMTB with a fixed fork and a torque sensor to optimize performance and handling.
Though it’s relatively small, the Bafang 500W motor is very mighty thanks to the torque sensor that measures the pressure on the pedals 1,000 times a second. This gives the controller a precise idea of how much output you need from the motor, allowing for a great riding feel you won’t get from other bikes in this price category.
To keep the price down, the brand has given the Boar Explorer a fixed fork. If you get the tire pressure right, then you’ll find this isn’t a big issue. However, you can always buy the optional extra inverted suspension fork for more comfort.
While the standard battery offers a decent range, we recommend you get the upgraded 960 Wh battery. The upgraded battery will take you a realistic 40 miles on average terrain.
Reasons to Buy
We would describe the Boar Explorer as a “sports SUV” e-bike that’s great to ride just for the sake of riding. When it’s set up right with the tires just soft enough to counteract the lack of suspension, you’ll find it an agile and powerful machine that weighs just 50 lbs — a full 20 lbs lighter than most of its kind.
Things to Consider
Unlike the similarly priced Surface 604 Hunter, this isn’t a bike for carrying gear into the wilderness. Instead, it’s a fun eMTB for taking on rough terrain and enjoying the ride. It has no rack and carries a maximum load of 285 lbs.
The Hunter, on the other hand, comes with front and rear racks. The Explorer is better suited to day rides and those you may enjoy with a daypack with water food and warm clothing.
