Pinkbike Grim Donut is a satirical yet functional prototype project created by
editor Mike Levy. It was designed to "skip the future" by taking 10 years of geometric trends (longer, slacker, steeper) and extrapolating them to a radical extreme, humorously suggesting what a mountain bike might look like in 2030. Project Origins and Design The Concept:
Levy calculated the rate of change in mountain bike geometry between 2010 and 2020 and applied that same difference to create a "future-proof" frame. Manufacturing: The frame was hand-crafted by
, a high-end Taiwanese factory, by welding together two downtubes to achieve the necessary length. Radical Geometry: The original V1 prototype featured a shockingly slack 57° head tube angle and a steep 83° seat tube angle Evolution and Performance
Despite being intended as a joke, the bike proved surprisingly capable in timed testing: Timed Testing:
Professional racer Yoann Barelli tested the Donut against his standard race bike and went six seconds faster on a two-minute descent during his first lap. Grim Donut V2: Following the V1 success, Pinkbike partnered with Pivot Cycles
to build a refined version. The V2 featured a slightly "steeper" 58° head angle
(marketed as "Turn Helper Concept") and used Pivot’s hollow-core aluminum construction.
It offered adjustable travel (165mm–172mm) and three chainstay length settings (460/470/480mm) to manage its massive wheelbase. Key Specifications (V2) Specification Intended Use Enduro, Downhill Frame Material Wheel Size Head Angle Seat Angle 513mm – 525mm Fork Travel
The project remains a highlight in mountain bike media for its "right amount of stupid" philosophy, proving that even extreme geometry has unexpected performance benefits in steep, technical terrain. collaboration for V2?
The "Pinkbike Grim Donut" refers to a radical mountain bike prototype series developed by Pinkbike to mockingly skip current design trends and leap straight to the "geometry of 2030". Initially conceived as an April Fool's joke, it evolved into a multi-part video series and a legitimate performance experiment. The Prototype Series
Version 1 (2020): Built in Taiwan by Genio Bikes, this aluminum mule featured a world-first 57∘57 raised to the composed with power
head tube angle and a massive 1,409mm wheelbase for a size small. Despite being "terrifying" to steer at low speeds, it was surprisingly fast downhill during timed testing.
Version 2 (2023): Developed with Pivot Cycles, this iteration aimed to be "less terrible." It featured a slightly steeper 58∘58 raised to the composed with power
head angle (making it the first bike in history "less slack" than its predecessor) and a refined DW-Link suspension system.
Version 3 (Conceptual): Mentioned jokingly with an expected release date of 2030, possibly featuring 32-inch wheels. The Grim Donut Video Game
To celebrate the project, Pinkbike launched a standalone Grim Donut Video Game. Players take on the persona of Mike Levy to ride the "unrideable" bike across levels inspired by British Columbia trails.

Pinkbike’s Grim Donut: From Ridiculous Prototype to Unblocked Gaming Sensation
In the world of mountain biking, few names carry as much weight as the Grim Donut. What started as an ambitious (and somewhat absurd) experiment by the team at Pinkbike has evolved from a 57-degree head-angle "bike from the future" into a viral gaming phenomenon. Whether you're a gear nerd obsessed with progressive geometry or a gamer looking for the Grim Donut unblocked experience, here is everything you need to know about the bike that broke the internet—and its own frame. What is the Grim Donut?
Created by Pinkbike 's Mike Levy, the Grim Donut was a prototype mountain bike designed to see what would happen if you took modern "long, low, and slack" geometry to its absolute logical extreme. The original specs were staggering:
Head Angle: 57 degrees (steeper than many downhill bikes but slacker than almost any enduro bike of its time).
Wheelbase: Roughly the size of a "Winnebago," measuring 1,409mm for a size small.
Philosophy: "2030 geometry in 2020," testing whether radical length and slackness would actually make a rider faster.
While it was initially mocked as a joke, the bike surprised everyone by setting record-breaking lap times in professional testing. Pro racer Yoann Barelli even noted it could potentially win races by a full minute on certain tracks. The Grim Donut Video Game
Because the physical bike was so difficult (and expensive) for the average person to ride, Pinkbike partnered with ASBO Interactive to release The Grim Donut Game. In this game, players can:
