The Keystone is my first e-bike having been a fat tire mtb enthusiast this was a no brainer, it is the most fun I’ve had on a fat tire bike. Love it !! thanks Borealis.
What a great bike, love how light weight it is and soooo smooth!
Bought this xl frame to replace my 5 year old crestone. There was nothing wrong with my old one (had 13,000 + miles on it) but the blowout price on the xl was so good i had to buy it. paint is incredible.
This is my third eFat and although I liked other two - the Keystone is just beyond. I set mine up with a Redshift ShockStop seatpost (hardtail with benefits!), Ergotec 45 degree by 50 stem, carbon riser bar, and Schwalbe Al Mighty 4.8 tires (328 Billy Flamingo studs per baby!) The T-type drivetrain blew me away so much I converted my other bikes.
I also received unbelievable service from the Borealis sales rep during purchase.
Simply heaven!
