Mobile Espresso Bike and 3D-Printed Cups for Coffee on the Go

Coffee lovers on the move—whether commuting, biking across cities, or just wanting a quick shot without a café—face the same challenge: how do you enjoy quality espresso without being tethered to a shop or heavy gear? A pair of UK design students and a Spanish innovator may have your answer, combining old-school mechanics, pedal power, and cutting-edge fabrication to serve espresso in unexpected ways.

Yes, you can now make espresso by pedaling a custom bike—and print your cup on demand using a 3D ceramic printer. One project turns pedal strokes into espresso shots, the other turns digital models into usable coffee cups in hours.

Pedal-Powered Espresso: The Velopresso Project

London-based designers Amos Field Reid and Lasse Oiva, both Royal College of Art students and avid cyclists, built the Velopresso—a fully mobile, human-powered espresso setup. Their goal? To create a bike-mounted espresso maker that’s completely off-grid yet functional.

The bike includes a modified hand grinder linked directly to the bike chain. Every five pedal rotations grinds enough coffee for a double espresso. That mechanical connection means your ride powers your shot—literally.

The heat source currently comes from an external camping stove, but the team is experimenting with using spent coffee grounds as fuel. That’s right: the byproduct of your drink could eventually help brew your next one.

The Velopresso isn’t just a gimmick—it’s a working prototype built out of passion for both cycling and specialty coffee. While still in development, it shows how creative engineering and a love for coffee can produce something truly unique.

3D-Printed Coffee Cups: Bernat Cuni’s Daily Design

Across Europe, Spanish designer Bernat Cuni has been exploring another angle of mobile coffee culture—disposable, yet highly customized, coffee cups. Through his “one coffee cup per day” project, Cuni uses emerging 3D ceramic printing technology to manufacture a new cup design daily.

What starts as a 3D model quickly becomes a physical ceramic cup, often with unconventional shapes and features. While not all are practical for everyday use, the speed and flexibility of 3D ceramic printing allow rapid prototyping and creative expression. The technology brings a fresh aesthetic and tactile experience to single-use coffee vessels.

This project highlights how digital fabrication can turn ideas into tangible objects in just hours. For coffee drinkers, it hints at a future where your cup is as unique as your drink—printed on demand, shaped by design, and eco-conscious thanks to precise material use.

Why This Matters for Coffee Culture

Both the Velopresso and Cuni’s 3D-printed cups reflect a growing trend: mobile, sustainable, and design-forward approaches to coffee preparation and presentation. These aren’t mass-market solutions yet, but they push boundaries in how we think about equipment, portability, and environmental impact.

For specialty coffee enthusiasts, these innovations demonstrate that great coffee doesn’t require a fixed location or traditional tools. Whether you’re brewing on two wheels or sipping from a digitally crafted cup, the future of coffee is flexible, creative, and increasingly personalized.

How Pedal Power Actually Works in an Espresso Bike

The Velopresso uses a straightforward mechanical system:

• A standard hand grinder is bolted to the bike frame.
• The grinder’s handle is connected to the bike chain or a gearing system.
• Each full rotation of the pedals results in a partial turn of the grinder handle.
• It takes approximately five pedal rotations to grind enough coffee for a double shot—about 18–20 grams.
• The rest of the espresso setup—filter basket, portafilter, and heating element—is also bike-mounted or portable.

The team hasn’t yet published torque specs or exact brew ratios, but the concept relies on consistent pedaling effort to ensure proper grind size and brewing pressure.

Can You Print Your Own Coffee Cup at Home?

Not quite yet—but the technology is getting there. Bernat Cuni’s process involves:

• Designing a cup digitally, often with artistic or ergonomic features.
• Sending the model to a 3D ceramic printer that deposits layers of ceramic material.
• The printed piece is fired in a kiln, just like traditional ceramics.
• The result is a food-safe, durable cup ready for use—often with intricate details impossible to achieve by hand.

Current printers are still expensive and slow for mass use, but the method showcases how customization and sustainability could transform everyday coffeeware.

Frequently Asked Questions

How does the Velopresso generate enough pressure to pull an espresso shot?

The Velopresso likely uses a modified manual or portable espresso machine (not fully detailed in the source) where the rider’s pedaling motion contributes to grinding the coffee, while a separate manual or mechanical pump generates the 9 bars of pressure typically needed for espresso. The exact pressure system isn’t specified, but the grinder is confirmed to be pedal-powered via chain linkage.

How many pedal rotations are needed to grind coffee for one espresso?

It takes approximately five full pedal rotations to grind enough coffee for a double espresso, which typically uses around 18–20 grams of coffee. Each rotation helps turn the grinder connected to the bike’s chain.

Is the Velopresso available for purchase or public use?

No, the Velopresso is currently a prototype created by two Royal College of Art students as a passion project. It’s not yet available commercially, but it demonstrates how pedal power can be used to create functional espresso on the go.

Are the 3D-printed ceramic cups microwave or dishwasher safe?

The article doesn’t specify, but standard 3D-printed ceramic items, once fired in a kiln, are usually microwave and dishwasher safe, much like traditional ceramics. Since Bernat Cuni’s process mimics conventional ceramic firing, it’s likely the printed cups can handle normal use.

Could coffee grounds really be used as a fuel source for an espresso setup?

The Velopresso team is experimenting with using spent coffee grounds as a potential fuel for the heating element. While not yet in use, the idea is part of their ongoing effort to make the entire system more sustainable and self-sufficient.

How long does it take to 3D print a ceramic coffee cup?

The article doesn’t provide an exact duration, but typical 3D ceramic printers can take several hours to print a single cup, depending on size, resolution, and complexity. The printed cup then requires firing in a kiln, adding more time to the overall process.
