One of the most surprising takeaways from our time on the Keystone was how simple it is to ride. The bike weighs 60 lbs, but it feels light by fat bike standards. There are several in the 70 - 90 lbs. range, after all. It was surprisingly easy to maneuver around on our local trails, and we even found it worked well with the motor off.
The Keystone felt versatile and enabled us to ride trails we'd otherwise pass over because they were too dusted with sand. The fun factor of a bike is high when you feel less restricted.
This was a third bear 'just right' scenario. The bike, unlike many fat bikes, does not supercharge the motor, which can make it hard to control on technical terrain, nor does it lack enough power to charge a hill.
Borealis has been making fat bikes for a long time-as evidenced by their owning the domain fatbike.com-and their first take on an electric bike is an impressive one. The Keystone has modern geometry associated with trail and XC riding, is spec'd with a host of desirable Shimano and SRAM parts, and lets the rider pick the tires ranging from offensive lineman to sumo wrestler sizes.
