2017 NAHBS: Portus Cycles Hardtail with a Pinion Gearbox

Alex from Portus Cycles was the late Ezra Caldwell’s biggest fan in Germany. After fighting cancer and documenting the process for six years before passing away in 2014, Ezra inspired many people, even today. For Alex, it became his inspiration and helped him through his own father’s battle with brain cancer. Ultimately, Alex’s father passed away, inspiring him to live life to the fullest and keep on keepin’ on with Portus Cycles. This bike is an homage to both Ezra and Aelx’s father.

Powered by the unique, made in Germany, Pinion gearbox, this hardtail was used in one of Germany’s 24-hour mountain bike race, Sleepless in the Saddle. If you’d like to know more, head over to Portus Cycles.

    That seat cluster is certainly a cluster, and I mean that as a compliment.

    That gear box junction/mount is phenomenal.

    For crying out loud, at least have the sense to spell Ez’s last name right. It’s “Caldwell”, with a “d”. Not Calwell. Signed, one of Ez’s friends, and yeah, FUCK CANCER.

    • For crying out loud, you could probably be a bit more tactful. I was going on 3 hours of sleep when I wrote this and had been shooting bikes for 4 days straight.

    I’m really curious about the Pinion gearbox. Seems to be a very good option to a Rohloff for a belt-drive 650b+ bikepacking bike. I’ve read a couple reviews that were pretty positive. The idea of keeping the bulk of the drivetrain mass close to the center of mass of the bike might handle better while riding or not.


    That is a really sweet rig.

    That “cluster” makes it look tall-bike ready! (don’t hurt me)
