2017 Philly Bike Expo: Engin Cycles Ti Mountain Hardtail – Jarrod Bunk

Drew from Engin is a framebuilding prodigy, a master of the chainstay yoke and arguably, the maker of the finest mountain bikes in the USA, perhaps the world. His advances in mountain bike design have spiked the well of the industry, pushing the envelope of geometry and detailing. All of this is ATMO, of course, but having been a longtime dan of Drew’s work, it’s amazing to see how flawlessly he’s adapted to the changing and sometimes harsh ecosystem of the cycling industry.

Drew designs, prototypes and machines his own yokes and dropouts from titanium. He then welds them together for a beautiful frame with a unique bottom bracket cluster that allows for the use of a standard q-factor crank. It’s easy to overlook these details, even on such a simple frame, yet as we’ve all heard before “God is in the details…”

    I’m a fan.

    Mindbogglingly good.
    The fit (and finish) of the yoke and how the chainring tucks in there… have your (Ti) cake and eat it too!

  • Kyle Marmesh

    Oh my, in love.

  • Gregory Ralich

    Are you positive the yoke was machined? Those layers look more like 3d printed layers than CNC passes!

      Answered my own question after a few minutes on the Engin ‘gram, here: https://www.instagram.com/p/BZ9YEAlHukC/?hl=en&taken-by=engincycles

      • Gregory Ralich

        Oh jeez this is getting more amazing by the second! https://www.instagram.com/p/BYy5HmFndkg/?hl=en&taken-by=engincycles

        • Yep. Drew’s a mad scientist of shred sleds.

          • Gregory Ralich

            I’m also just eager to see more 3D printing in the industry – excited to see where these mad scientists and evil geniuses run with rapid prototyping equipment as the machines get cheaper and cheaper.. I even put Outer Shell’s laser cutting in this bucket.

          • Agreed!

          • slickfast

            Me too, the tough thing is whether we can trust the metal 3d prints. Right now it’s mostly sintered metal powder, so it’s not nearly as uniform or as strong as a forged material. Translation: it’ll be heavier. But there are some cool designs that can be made to make up for it?

          • Gregory Ralich

            Totally – probably start with bag and accessory/component mounts before a yoke!

    that Sharpie …

    • RF

      No Sharpie.

      • #DirtyRoadie

        photo one under the front wheel – didn’t get pShopped like the stick.
        super hot bike

        • RF

          Oh THAT sharpie. I thought you were referring to my paint job.

        • I couldn’t get the shadow to not look like total shit, so I left the sharpie in.

          • Brad Quartuccio showed me a trick last year: Take 1 or 2 medium sized binder clips, remove the handles and place them on either side of the tire/wheel. Works really well on flat ground holding the bike in place and photoshopping them out is relatively easy if they are visible.

          • I do that at NAHBS. :-)

    • They work really well!

  • RF

    Been riding this thing just about every day since the Expo.

    It rips.

  • Jeff Haye

    Want and need!

  • Sarkis

    Wow! Speechless. Darn man… I haven’t got the dough and i also do not want to know the price of Drews handywork. Actually i do not want to have another look before i get any stupid ideas.

  • caliente

    Holy Wheelbase!

  • Ceol Mor

    Love hardtails! This is a great looking machine.

  • AaronBenjamin

    That yoke is hot!
