BACK TO THE FUTURE. BMW Motorrad Concept R18

Posted on May 25, 2019 by Scott in Bobber, Classic. No Comments

The cat is finally out of the bag. When we say cat, we mean big black purring panther. We caught a glimpse of the BMW 1800cc airhead engine in Austin, Texas last month at the Handbuilt Show. Revival Cycles did a stellar job showing off this beautiful 1800cc boxer engine in the titanium framed ‘Birdcage’. Now here is the highly anticipated BMW Motorrad Concept R18 in all its glory. Launched at the very fitting Concorso d’Eleganza Villa d’Este, this R18 concept motorcycle has put a modern twist on BMW’s classic boxer engine design from the 60s and the classic lines of the BMW R5 from the 30s.


Concept Bike: ‘Monocasco’ by Art-Tic Design

Posted on March 28, 2012 by Andrew in Other. 34 comments

It’s been quite a while since we’ve had a decent concept bike on this here ol’ Hot Tubes blog and what better way to celebrate a triumphant return than with this insanely cool concept out of the offices of the Art-Tic design studios, located smack bang in middle of downtown Barcelona, Spain. Designed for the the Spanish Marque Ossa, it represents the company’s first non-trials foray since the early 1970s. The brief from Ossa to Art-Tic was the stuff that any bike designer only dares dream about; take a classic race bike from the 1960s and update it for the 21st century. The result? A bike any rider would only dare dream about, and it has a Wacky Races sticker on it. Any cooler, and it’d turn nipples into diamonds at fifty paces. Mujers and hombres, feast your eyes on this.


Interview: Andres Uibomäe – Renard Motorcycles

Last year we featured this carbon fibre Renard Motorcycle which was lighting up the switchboard on many motorcycle sites around the world – including this one. Unfortunately, we couldn’t make it to Estonia to interview the team behind the bike but fortunately someone else did. That someone was Lauri Poldre from a CAD drawing collective called who was kind enough to send us his comprehensive interview. Enjoy…


Interview: Gregory Thüne – Industrial Designer

Posted on May 5, 2011 by Scott in Café Racer, Other. 32 comments

We have all seen amazing concept bikes created by Industrial Designers that never see the light of day. They are created on the computer and spend the rest of their days in the pixel world. Well, this Fiv0 concept was designed by Gregory Thüne who is trying to take it into the next stage — production. We asked Greg a couple of questions about this stunning bike and we cross our fingers and hope it does manage to do a “reverse Tron” and make the jump from pixels to the real world.


Lito “Sora” – Electric Superbike Concept

Posted on April 16, 2011 by Andrew in Bobber, Other. 18 comments

It’s interesting to see the way electric bikes are creeping their way into all aspect of modern motorcycling. Whether your thang is crotch rockets, customs or choppers it seems that electric bikes are here to stay. So too the electric revolution is making it’s mark on today’s concept bike designs. As recently as a few years ago you could put money on the fact that a concept bike would have either a Harley or Ducati Vee stuffed in it as a matter of course. You could even argue the case that the designers weren’t really bothered what made the bike of their dreams go, just as long as it made a heap of noise and didn’t jar visually with the rest of the bike.


Café Racer Concept

When it comes to countries I don’t know a lot about, Estonia is probably near the top of the list. The one thing I do know, is that one of the more interesting motorcycle designs from last year came out of Estonia – the love it or hate it Renard Grand Tourer. So why all the interest in Estonia? Well, last week we received an email from an artist named Kait who lives in Estonia. Kait specializes in post-apocalyptic sci-fi drawings but told us that he recently “spent an entire day looking at all the pages on Pipeburn and decided to build a bike”. The problem was, Kait doesn’t know anything about bikes. “Because I don’t know how to build one, in fact, I don’t know anything about motorbikes, I cheated and used a 3D application instead” he says. “There are many logical and technological errors, and probably not very comfortable to ride”. The wooden tank might not be to everyones taste, and it may be carrying a bit too much weight for a café racer, but we think Kait deserves his ‘café racer concept‘ to be shown to a wider community — so power down your ion phasers, depressurise your extra-vehicular spacesuits, and park that lunar module in a geo-stationary orbit while you take a few minutes to check out this beautiful concept bike.


Moto Guzzi Big Mono Naked SD Concept

Posted on February 2, 2011 by Andrew in Other. 20 comments

Our Imaginary Garage sessions on Pipeburn are all very good and well but if we ever wanted to ramp things up just a little and start doing some 3D modeling, I’d be much more than happy seeing a bike like this roll out of the other end. These stunning renderings are by Italian industrial designer Paolo De Giusti, who has drawn inspiration from an older generation of single cylinder Moto Guzzis from the 50s that have been all-but-forgotten since the company’s success with it’s twin cylinder V90.

And if that’s not unique enough, he’s also gone and made it a 903cc turbo-diesel engine with a hydraulic transmission for the estimated 150 horsies and 133 ft/lbs of torques (!) to slosh through. Bolt a 30 lt (8 gallon) tank and you’ll have a bike that would ride all night, which is exactly what Paolo intended. “Ideally this bike, with a range of 550 miles, is designed to run for hours in the now-defunct Milan-Taranto open road endurance race.”


Harley Davidson 883 Scrambler

Posted on November 8, 2010 by Scott in Scrambler. 21 comments

Only last week Harley-Davidson announced that they were planning to restructure the company and wanted to be quicker to market with new products. Well, young Italian designer Luca Bar has created this Harley Davidson 883 Scrambler concept that should be one such product.

Luca designed this scrambler with the European market in mind – he is Europeon after all. “The project gives a nod to the years when there were no major endorsements, the bike was the bike, one and good for all”, ready to adapt” says Luca. “The horses and the chassis are enough for the scope, the fork gets stiffer springs and at the rear longer units. The wheels 18″ front and 17” at the rear fit very Italian Pirelli Scorpion Sync and the secondary transmission needs to be a chain instead of a belt. The classic saddle and tank shape, form the overall look of the bike. The protagonist of the right side is the “line” of the exhaust, tall and straight, half-way between the European regularity bike and American Drifters.”


Concept Motorcycles

These radical concepts look like they could have been created by maverick designer Phillipe Starck. In reality they are the brain child of young english designer Paul Van Denton. After completing a masters in vehicle design from the Royal College of Art in London he now works for industrial designer Ron Arad. But Paul’s true love is designing motorcycles – a lot of the time in his lunch hour. Paul says he is “unsatisfied with bike designs at the moment” and wants to build nostalgic rides with a futuristic twist.


Pony Express

Posted on April 28, 2010 by Scott in Racer. 3 comments

This beautiful machine named ‘Pony Express’ was built by brilliant Israeli industrial designer Amir Glinik. Unfortunately he didn’t build it with a wrench but in 3D with his computer mouse. Amir’s artwork is some of the best we have seen, his bikes look so real you can almost smell your jeans burning on the pipes.
