Japhy

Japhy was born out of a desire to fast track your adventures and maximize your ride time. From
backyard singletrack to long days in the alpine, Japhy will get you out there quickly while
putting a huge smile on your face as it flows effortlessly through the landscape.

29" wheels for up to 2.8" tires

Hardtail with 120mm front travel - can accomodate up to 130mm fork

4130 Chromoly frame - custom Quad-butted tapered and seamless DOM tubing

Portage Dropout - for adjustability, singlespeed and upgradeability

With size-specific headtube lengths, steeper seat tube angles, and revised reach lengths for 2023, the new Japhy provides a more accurate fit and maximizes handling and comfort for every sized rider.

The shorter and steeper seat tube delivers a pure trail bike experience and the easy to use and easy to maintain full external zip-tie cable routing makes it more user friendly when far away from civilization.

A hardtail can be the best choice for getting way out there without worrying about complicated setup and maintenance. Durable and dependable means fewer things to go wrong. Japhy is your go-to bike for times you just want to climb on and roll out.

Go deep into the backcountry on that remote singletrack route or simply rip around on your local trails, this is the bike to get the job done. Japhy tackles any terrain you throw at it and gets you back again on every ride.

Esker Cycles - Built for the Back Country
We here at Esker enjoy long rides into the wild spaces and are proud to say our bikes are truly Built for the Backcountry. That means they are designed and built on three tenets:

Durability

We build our steel hardtails from 4130 chromoly for the utmost in durability.
Our proprietary quad-butted, seamless tubeset provides a greater strength to weight ratio than other 4130 frames on the market by engineering it specifically for its application while the complete Electrophoretic Deposition (ED) coating of the frame resists corrosion inside and out for an extremely long and worry-free life.

Refined Geometry

With specific geometry to suit the riders needs for each different
model, we have designed and developed a quick and responsive ride quality for the new Japhy. Utilizing size specific headtubes and shorter and steeper seat tubes we have given this bike a more playful trailbike feel that will make you want to throw it around the corners and pop off every little bump in the trail.

Ride Quality

Steel is real - engineered steel is even more real. Our frameset utilizes a proprietary heat treated 4130 chromoly tubeset that is strong and durable with a fully tuned ride quality specific to each size.
This custom drawn, externally tapered, seamless, and quadruple butted tubeset gives it more compliance and is lighter weight while also increasing torsional rigidity and overall strength.
