Found: Bamboo & Carbon Fiber Fat Bike with Gates Belt Drive, Lefty Fork!

Diller Designs bamboo and carbon fiber fat bike with Lefty fork

This bamboo and carbon fiber fat bike was built by Drew Diller as a hobby project inspired by the folks at Boo and Bamboo Bike Studio.

The frame uses the same type of bamboo as those companies, Dendrocalamus strictus” or “iron bamboo”, which Diller says is quite strong and surprisingly crash resistant. The carbon wrap is what he calls “garage quality” that comes on a spool of carbon fiber strands that’s wrapped around the joints. Diller says he’s looking for something stiffer and to learn to use more high-tech construction methods.

To get the Lefty fork to hold the fat tires, he ordered 17.5mm offset custom clamps from Mendon Cyclesmith and built the front wheel up with Large Marge rims and a standard Lefty hub. The rim offset is flip-flopped front to back to keep the tire from rubbing.

The clamps only work on the older Lefty’s with clamped-on crowns, not the newer one-piece designs. Braking is handled by STI Versa shift/brake levers mated to Avid mechanical brakes, and he’s rigged it to an Alfine 8 internally geared hub to make the going a bit easier.

This is Version 2. The original, shown below, was a fully rigid model. Now that Salsa’s put the idea of a full suspension fat bike out there, Version 3 will see Diller taking a stab at a dual bonier. Ultimately, he’s looking to start a business building bamboo bikes full time. Good luck, Drew, looks like you’re off to a solid start!

This bike has every buzz item a bike can have except electronic shifting.

Fatty tires, bamboo, carbon, gates drive, lefty fork, monster cross… too much industry buzz!

Who is the manufacturer on the handle bars?

steve - 02/17/12 - 12:02pm

way to go Drew, been following this thread on mtbr for a while now.

AlexK. - 02/17/12 - 12:34pm

Awesome!

Thats really something. I would probably never buy one (mostly because acquiring such a creature would probably take way more buying power than I have), but I would sure love to ride it around for a bit.

satisFACTORYrider - 02/17/12 - 2:16pm

that looks fun as hell to ride

Drew - 02/17/12 - 3:54pm

Gian – the only things on this bike that truly buzz are the tires =)

Peter Rhodes - 02/17/12 - 4:02pm

The bars are Salsa Woodchippers from the looks of it.

Joe T - 02/17/12 - 4:11pm

wow, add road hydro levers and this has every trend in the market today!

gee - 02/17/12 - 4:23pm

probably a dumb question, but what kind of handlebars are those? 31.8?

druidh - 02/17/12 - 4:47pm

Bars look like Salsa Woodchippers

Drew - 02/17/12 - 4:49pm

gee – 31.8 clamp On One Midge bars.

I can assure everyone this wasn’t meant to be a buzzword bike. Not at all… the Lefty and belt in particular are just means to an end (currently available fat tire suspension for the former, and lack of maintenance after messy weather rides).

all it needs now is an integrated seat post.

Xris - 02/17/12 - 10:51pm

Lefty fork, belt drive, bamboo, carbon, needs the following.
di2, integrated post, 11sp, carbon crank, tuned frame, and leather coffee cup holder.

Igor - 02/19/12 - 9:23am

It’s just DI2 Alfine away of being the ultimate buzzbike.

Turbofrog - 02/19/12 - 9:49pm

Good lord I cannot believe all the haters here. It’s a super fun looking ride built with a great concept and great components. The justification for all the aspects of it makes perfect sense, so I really don’t understand why everyone is running it down. Are you all so jaded?

Eric NM - 02/19/12 - 11:11pm

@Turbofrog: Couldn’t agree more–way to call ‘em out.

@Drew: beautiful work! Kudos on the execution; I’d love to ride it as well. Gorgeous.

Drew - 02/20/12 - 4:41pm

Turbofrog – hehe it’s all good. The bike’s feelings certainly aren’t hurt, and I am my worst critic. The bit I chuckled at was the coffee cup holder: I was thinking more like a flask, not a big fan of coffee =)

Grip Studs - 04/23/12 - 12:07pm

Unbelievably awesome bike, Drew! Props on this one. That is such a righteous bike!

Sam - 07/31/12 - 1:47pm

I think it looks great!
Keep up the good work.

(sticks tongue in cheek and winks) little commercial for my liking, would have loved to seen something a bit more custom… perhaps a saddle carved out of the horn of a unicorn might give it that one off look your going for. ;) but in all seriousness… (stands up from computer and gives a light “golf clap” ) nice work m8.

James Romeyn - 05/24/13 - 1:31pm

That is the coolest and more desirable bike I have ever seen. Sign me up now.

Interestingly, bamboo ply is among the best natural (vs. man made synthetic composite) materials for speaker enclosure panels (the other ideal natural material is much more costly and almost certainly performs better, enclosures milled from solid aluminum billet with only one removable panel). Bamboo is very high-self damping in the audio wave band and of course is a renewable resource. For this application, the better is self damping the lower is secondary noise and the better is performance.

I presume, till proven otherwise, that bamboo’s self damping quality extends to improved performance for bicycle frame. Good on bamboo, good on the designer!
