Similar to most brands nowadays Polygon has embraced the e-bike movement. Previously, their only offering in this area was the Urban styled, Path-E. Now, they’re breaking into the e-mountain bike market with the Entiat-E. It’s a 27+ hardtail trail bike that’s built for a blend of comfort and performance.
A closer look at the frame design
The Entiat-E has an aluminum frame with 148x12mm Boost hub spacing, internal cable routing, and an integrated downtube battery mount. It also uses Polygon’s 2HRU rear thru-axle to quick-release conversion system, aggressive FWG frame geometry, and TPro build and design.
The specifications

It’s built up with a Shimano XT rear derailleur, cassette and shifter, along with an e-bike grade crankset and chain. Stopping power is provided by Shimano hydraulic brakes. Up front, there’s a Rockshox Recon Silver RL with 120mm of travel and Boost spacing. And it rolls on 3.0″ tubeless ready Schwalbe Nobby Nics. Though the photos show a dropper post, the spec sheet tells a different story. Ultimately, internal stealth routing for a dropper post is there. So even if it’s not included, a dropper is compatible.
