I ride a Pista, and for a long time I’ve thought it – my chrome-moly limited edition Bianchi – the most perfect Pista ever built, aesthetically and trackside. German übergestalter Ralf Holleis has just broken my dream, creating the above stunning super lightweight track bike, the VRZ 2 BELT, resplendent with 3D – lasercused – printed titanium lugs ::::
Holleis’ VRZ 2 sheds light on just how much work goes into creating a flawless 3D printed product. Check the video above. Holleis’ process isn’t the most straightforward, but it’s superneat for creating custom frames in a relatively short time.
Regardless of whether you would want to tackle a project like this on your own, it’s worth taking the time to watch the video below to see just how much work goes into many of the 3D-printed projects that continue to make the rounds online.
Anyone interested in replicating this process can change the bike’s geometry to suit their own specs, generating your own unique lugs is totally dependant on software, neat huh? The pieces are produced via process called laserCusing, and then the printed parts are finished and bonded to the tubes.
WTF is LaserCusing? LaserCusing technology was developed specifically for the mould making. Components produced by LaserCusing can be used without any restrictions in moulds for plastic processing and light metal die-casting. Any conventional finishing method such as milling, turning, grinding, polishing, coating or nitride surface hardening can be applied to parts made by LaserCusing.
LaserCusing is sometimes confused with direct metal laser sintering technology – DMLS, however, there are huge differences that make LaserCusing suitable for applications in mass production. More on laserCusing? check: www.lasercusing.nl
Disregarding my obvious penchant for Fixed Gear Pista’s, as an object, 3d printer or not, Holleis’ creation ticks all the boxes. It uses a solidly lightweight titanium-alloy in the printed parts, glued to ultralight, dry-carbon tubes to finish off the structure. Lightweight components like wheels, a THM crankset, propelled by a noiseless belt drive, this cycle is stunning.
All up, Holleis’ VRZ weighs in at just 4.9 kg/10lb, making it a serious track contender. The above incarnation – silver on black – is by far my favourite finish.
However, on the street I’d most likely stick with my Bianchi, there’s no question Holleis’ 3d printed VRZ would win the unofficial “Best back in the rack,” contest at my local watering hole, but the chain I’d need to keep it mine would weigh more than the bike.

RELATED! Hoverbike, A Baby Chinook is Born
What do you get when you combine the agility of a motorbike with the lift of a hovercraft – aside from the obvious thrill – Chris Malloy’s Hoverbike, the ultimate all terrain vehicle. Malloy’s Hoverbike is set to take motocross to new hieghts.
With a BMW 1170 cc 4-stroke engine delivering 80 kW driving two ducted propellers, the inventor of the Hoverbike, Chris Malloy, reckons with its high thrust to weight ratio, the Hoverbike should be able to reach an estimated height of 10,000 feet and reach an indicated airspeed of 150 knots – 275 kmh / 170 mph.
Malloy told Grilled “I’ve loved designing aircraft since childhood. The thing that kicked off the design of the hoverbike was a comment my helicopter instructor Chris Townsend made, which was that the Robinson R22 was an airborne motorbike.
I didn’t quite agree, so I set out to build a robust workable flying motorbike to prove my point” Read the full article »»»»

Lycra Clad isn’t one of our favorite thoughts, we groove to vinyl, love pvc, lust after leather and definitely dig denim. The thought of lycra clad cyclist though, not good! All spruced up with kevlar uberbikes and faux sponsorship the latte sipping cycle brigade is not our bag.
So when we came across furniture maker Seth Deysach and his American Black Walnut – even the wood is sexy – cycle we had to dig deeper. It all started when Deysach was invited to be part of the Object Society design show in June 2010, Deysach decided to create something special for the bash, something that combined two of his passions, creating things in wood and cycling :: Read the full article »»»»

The New Zealand makers of a one-person jetpack hope to have it on sale by the middle of next year. The Martin Aircraft company says its jetpack can reach speeds of up to 70 kilometres per hour and soar 1 kilometre high. The Christchurch-based firm has been testing its prototype 12 via remote control.
The New Zealand Civil Aviation Authority said the jetpack has now been issued with an experimental flight permit for development test flying, which allows someone to pilot the aircraft.
Martin Aircraft says it has had 10,000 enquiries from people keen to take to the skies, but it is likely to first sell the jetpacks to government and emergency agencies involved in search and rescue and defence :: Read the full article »»»»

Three wheel motoring has been around for a bunch of time, from the extreme Davis D-2 Divan, to the pedestrian Reliant Robin. The most successful incarnation to date has been in the guise of scooters –like Piaggio’s MP3, and Peugeot’s clever HYbrid3 – agile, quick and just a little sexy, in an offbeat kinda way.
Indeed, the very first motor-car was a 3 wheeler, the 1860s Benz Patent Motorwagen, still history isn’t ever a great reason to repeat something, unless of course you’ve come-up with something as nifty as this! PS: I want mine in black please :: Read the full article »»»»
