Overview
WEATHER READY, WHETHER YOU ARE OR NOT.
Grab your Big Iron, throw on some Marty Robbins, and hit the snow or sand with the updated Revel titanium fat bike. Progressive geometry and UDH ready, this modern titanium steed will be your trusty companion on any snow or soft-surface endeavor. Its built around the biggest 27.5 fat tires on the market with perfectly balanced and progressive geometry to be fun on any terrain. It even won Outside Magazine’s best fat bike of the year in 2021, we made it even better since then. Named after the famous western tune “Big Iron”, this bike is designed to be the right tool to get the job done. Whether it’s a short weekend on groomed single track or you’re heading out on a multi-day journey, the modern geometry and stiff-yet-supple titanium frame make the Big Iron the perfect choice whenever you’re pulling out the fat bike.
Key Attributes
The CBF™ focuses the center of curvature in a very finite area on the chainline/top of the chainring, pointing the pedaling forces directly where you want them.

As far as versatility goes, I have yet to find a bike that packs more into a single package. I’ve ridden my Big Iron unloaded on rocky, rooty Northeast enduro trails, and—though it might not be the optimum choice—it handled the task with aplomb. On the other hand, I’ve loaded it up, and ridden high-mileage days in total comfort. Read more...

We do now! Well, in a way, we always have… our sister company, Why Cycles, has been manufacturing the most advanced titanium bikes in the world since 2016. We're retiring the Why Cycles brand, so now you can find the most advanced carbon and titanium bikes on the market under one name - Revel Bikes.
Revel titanium frames are lovingly hand-built in the same family-owned and operated factory in northern China used by Why Cycles for a half-decade. All Revel bikes are then assembled and shipped from our facility in Carbondale, CO.
Most! Max clearance 27.5 x 4.5″ tires, 26 x 5.0″ tires or 29 x 3.0″
One that fits! We love the bags we've seen and used from companies like Rogue Panda, Oveja Negra and Good Busy Gear.
Yes! Check with Rohloff for specifications.
Yes! Check with the belt drive manufacturer for specifications.
We recommend using some rubbing alcohol and a Scotch Brite pad and scrubbing gently in a "shoe-shine" motion (one direction or back and forth, not circular), then wiping down and finishing with a light coat of furniture polish like Pledge. This should work for both oxidation and light scratches. The graphics are sand-blasted into the frame, so you won't hurt them if you use a soft touch.
15-18Nm for the dropout bolts, 3-4Nm for the tensioner bolt
M5x0.8x35mm Stainless steel cap screw
We've updated all Revel Ti bikes with SRAM UDH (Universal Derailleur Hanger), so replacement hangers are easier to find and your bike's drivetrain is more future-proof against manufacturer updates down the line.
Absolutely! All Why Cycles and Revel Bikes frames come with lifetime warranties and a generous crash replacement program for the original purchaser. If anything does happen and you need a replacement frame, it will most likely be replaced with a Revel branded titanium frame, but we’ll get you back to riding ASAP!
