Shopping for an all-terrain e-bike usually means choosing between real off-road capability and a reasonable price, so I looked closely at Vanpowers' GrandTeton-Ultra to see if it splits the difference.
First impressions
It's built around a 760W peak motor good for 28 mph, with a smart module handling ride data and assist modes. That output puts it ahead of Vanpowers' own commuter-focused UrbanGlide line, which tops out closer to 725W.

Range and build
Vanpowers rates the GrandTeton-Ultra for up to 93 miles of range per charge — among the longer ranges in the lineup — and every Vanpowers frame is tested to 150% of the ISO 4210 structural standard, with the electrical system and battery certified to UL 2849 and UL 2271 respectively.
Is it worth it?
Regular price is $2,599, and it's currently part of Vanpowers' Winter Adventure Deals at $1,399 (save $1,200). Every bike ships with free shipping, a 30-day return window, and up to 6 years of warranty coverage, which is a meaningfully longer warranty than most e-bike brands offer.
