Hello Space Cake!
The new all-road bike from Sour is designed to take you further, faster.
The Space Cake can take you anywhere the roads go—“road,” of course, being more of a theory than a rule..
For the last five years, we’ve had this itch that something was missing. Deep in the back of our minds, we knew that a road-plus bike—something fast and efficient but still built to get weird when the road turns rough—would be the perfect addition to our lineup. It took time to nail down the right geometry, tubing, and design details to create a bike that stayed true to Sour’s adventurous spirit.
Now, after countless prototypes and test rides, the Space Cake is here: a road bike that blends speed with the durability to tackle all roads, whether they’re paved, or “paved”.
Roads are just a suggestion
The Space Cake may be the most “road” bike we’ve ever made, but don’t be fooled—it’s still got a bit of that playful spirit Sour is known for. With geometry that’s tuned for long road days but a durability that says ‘bring on the rough stuff,’ it’s made for for when that perfect stretch of asphalt turns into an irresistible gravel path. Ride farther, ride faster, and don’t be afraid to get a little adventurous.
Road bikes a lot different than they used to be. Gone are the days of skinny tires! In an era where usability reigns supreme, the Space Cake is king. We designed this bike to do go farther than you thought you could, and carry you back home too.
Made to Go the Distance
Designed with endurance in mind, the Space Cake is all about going longer and pushing your limits. With a road-focused frame built to handle big miles, it’s comfortable, light, and efficient enough to keep you smiling through epic rides. Whether you’re leading the pack on a group ride or setting out solo for some solid-state training, this bike is here for the long haul.
We love mountain biking, it’s at the core of our DNA, but just as any well-adjusted mountain biker will tell you, a touch of endurance never hurt your berm-slashing game. All-road bikes and gravel bikes are at the heart of our off-MTB-season riding – filling in the gaps between wet and dry season, fitness gaps, or just the gap between your house and the office!
Looks fast, goes anywhere.
Why choose between speed and style? Like every Sour model, the Space Cake comes with our signature custom powder coating, so your bike can turn heads on the tarmac or the occasional gravel detour. Bold, classy, or a little offbeat—it’s up to you. After all, just because you’re chasing KOMs doesn’t mean you can’t look good doing it.
Don’t lie, going fast is really, really fun. While going fast is sometimes also really, really hard, the Space Cake makes it as easy as possible. We designed tubing and frame parts to be as light and efficient as possible. Plus, you’ll be able to full-send every bit of gravel on the weekly group ride, so you can always close that gap if you need to!
The Ultimate All-Road Weapon
This is Sour’s take on a road bike—light, responsive, and built for speed, but not afraid to ignore the rules. It’s for the roadies who like to get a little weird, the MTB riders looking for a fast training machine, and anyone who sees a gravel detour as an opportunity, not an obstacle. So, go ahead: hit the smooth stuff, seek out the rough patches, and leave the route up to your imagination.
It’s been a long time coming, building an all-road bike. No joke, it’s been in the planning hopper for more than three years at this point. All that goes to say that when we finally made the step, went “full-roadie”, we really wanted to do it right, and do it our way!
