Behold the Infinity Cycle, the world’s first double-decker touring bike

The Zenga Bros’ curious yet ingenious Infinity Cycle lets two riders swap positions mid-ride, carry all the essentials, and keep moving indefinitely. It’s just embarked on a tour, powered by Benny Zenga, his wife Emily, and their twin five-year-old boys

Benny Zenga, a self-described ‘cinemacyclist’ from Vancouver, Canada, designed the Infinity Cycle 10 years ago – a bike built so two riders can switch positions mid-ride, allowing them to keep moving without stopping. Now, his family has set off on an updated four-person version, touring around Vancouver to promote their Be a Fool Kickstarter campaign. Let’s have a closer look at the two-person design and how it all started.

The Zenga Bros are a family who have spent more than two decades experimenting with unconventional bike designs, particularly tall bikes, and even filmed a short documentary with Red Bull titled ‘Tall Bikes Will Save The World’ . Benny Zenga’s adventures began with hand-me-down bikes, and nowadays, cameras and bikes define how he moves through the world.

“Tall bikes are something my brothers and I discovered through trial-and-error making art bikes,” says Benny.

“They were always really fun and seemed to stick around, so we naturally didn’t stop creating tall bikes – and then at some point, the ridiculous nature of it became ridiculously practical. Almost twenty years later, it’s become the only bike I want to take to the grocery store or travel across the world on.”

Over time, their tall bikes became moving workshops, allowing them to carry all the supplies needed. “You’ll see a bike give birth to another bike and skateboard ramps built in unexpected places,” says Zenga.

This passion for reworking and reimagining bicycles eventually led to the creation of the Infinity Cycle around a decade ago – a design that allows two riders to share the workload and keep moving without stopping.

Benny explains the motivation behind the idea: “The only real problem with bicycle travel – tall or otherwise – is that it’s human-powered and humans get tired… Since e-bikes don’t exist in our world, we had to get creative.”

Unlike a traditional tandem, which also lets two riders share the workload, the Infinity Cycle stacks riders on top of one another – essentially a double-decker bike – with space to store supplies, and carry whatever else is needed. The idea is that when the rider on the bottom gets tired, they move to the top, and the rider on top moves to the bottom, creating a continuous cycle that keeps the bike moving forever.

The Infinity Cycle comes packed with practical and quirky features. It’s equipped with three large front lights, plenty of front and rear reflectors, mirrors, and bottle cages. A ladder at the rear allows riders to climb to the top bike, while panniers and boxes provide plenty of storage. A large undercarriage adds more space to carry supplies.

In true Zenga Bros style, an assortment of spoons dangle from the frame at the rear, adding a playful touch to the touring setup.


Benny, his wife, plus their twin sons Oly and Ike have just started an adventure on the latest version of the Infinity Cycle, mounting four people, as they go on an open-ended tour in Vancouver to raise awareness for the Be a Fool book.

“With two riders, the Infinity Cycle could ride forever – now, with four, it will be able to go even further”, says Zenga.

Benny and his brother Willy Zenga have documented their adventures in the book, which they are currently funding through a Kickstarter campaign. The project is over 60% funded at the time of writing, and aims to inspire readers to tap into their creative potential by sharing 25 years of unconventional projects and adventures.

"All that's required is an to roads policing" - that's a big all... Although no doubt the "idiots just keep coming" aspect does apply: https://www.bbc.co.uk/news/articles/cz9lel2wz93o "Man charged after car crashes through bowling alley" - luckily they only skittled over skittles.

Almost any change to roads and streets is accompanied by a period of heightened danger, and in the UK "look out for cyclists" will need to be learned... practically. And over the time it takes for cyclists to become a regular feature. OTOH once (if...) good designs are in and frequent enough such that drivers encounter them AND the cyclists on them regularly (another big if) I don't think they should be much more difficult than a footway to deal with. These things are all over NL - don't have the collision stats but they should. (NL isn't perfect but collecting info on the safety of designs to feed back into better designs as required is part of the "sustainable safety" philosophy - if they're really a killer I think they'd be altering these.)

I'm in the happy position of agreeing with everybody here! I've never considered a bike with a stand, yet I'm impressed by the ingenuity and adaptability of this axle. I tow a Yak Bob with a Robert Axle, employing my El Cheapo Vitus gravel bike and I just have to be very careful where I stop. Hedges are generally a dead loss, and I seek walls, telegraph poles and signposts and generally lean the widest part of the Bob against it. One very awkward task is removing the two steel pins which lock the trailer arms onto the special mounting slots on the Robert axle, and when you have one out, the sodding weight in the trailer can twist the whole caboodle and bend the Bob fitting before you can get the other out and unhitch. I doubt if a stand would help with that. You can imagine that this combo is a real pain when you have to get it over the bridge at railway stations, and it nearly resulted in Merseyrail nearly parting me and the trailer on the platform from the bike on the train. It's a long story for another time. Another axle example recently featured on here, with a 12mm front axle bearing the Herculean weight limit of a monster American front rack.

This has nothing to do with the type of bike - it's the type of behaviour that's the problem. Banning the sale of such bikes will not curtail the behaviour. They'll just find another type of vehicle and continue to drive dangerously as there's such a lack of enforcement. I'd sooner see them ban the bally. But really, all that's required is an improvement to roads policing.

The EAPC Bill is welcome, but full of holes. What's to stop an overpowered but temporarily limited e-bike being sold and subsequently delimited? This is often a trivial process.

@KiwiMike Yeah, in my over four decades of riding all over Europe I've never 'been for a ride in the countryside'. That must be it. Or, and I know this is a wild concept, you just accept that I just voiced my personal experiences and never missed a kickstand, like I wrote. Anyway, what's the big horror of laying your bike on its side for the very few occasions where there is nothing to lean your bike against?

Ds2025: where they are going wrong is that they are crushing the motorbike rather than the person sat on top of it. If they did the latter this issue would be solved in less than 24 hours.

I came this way today with the car boot sale in operation. There was a marshal at the entrance, who stopped a car turning right across the cycleway as I was approaching. So that certainly works. I think it necessary for the marshal to be there, I couldn't say if the driver would have turned if he hadn't been there but you always have to suspect the worst. Unfortunately there is no marshal at the exit, and there was certainly a car stopped across the cycleway as I was approaching it. But he pulled onto the road before I reached it, and the following car stayed off the cycleway as I went through. Ideally there should have been a marshal there too. On the whole, though, it's a really high standard piece of infrastructure. Just a pity it doesn't extend a bit further.

“absolute carnage” So right! Just look at the bodies piled up, blood running in the gutters and injured people limping away. It's a bit of a problem with a road, delaying some people for minutes at a time: it isn't carnage, let alone 'absolute carnage'. Anyone who exaggerates so ridiculously really shouldn't be allowed to comment in public, unless they want to demonstrate their idiocy to all and sundry.
