Urwahn & Schmolke team up for striking 3D printed steel bike

Copper-plated road bike is available in a limited edition

German brand Urwahn Bikes has unveiled a 3D printed steel frame that's built up with lightweight components from Schmolke Carbon, and it's certainly a head turner. 

The first thing you'll notice about the frame is that it lacks a seat tube – or you could say that the seat tube and seatstays are combined – so how does it perform?

"The velodrome field test quickly showed the effect of the combination of steel and carbon – a comfortable geometry with brute bottom bracket stiffness meets aerodynamic lightweight construction," says Urwahn.

"The elastic suspension of the rear wheel guarantees additional riding comfort without sacrificing bottom bracket stiffness. This effect is particularly noticeable on longer rides and/or uneven surfaces; a decisive advantage over the competition."

We've not even seen this bike in the flesh never mind ridden it, so we can't comment on the ride quality ourselves. We're just showing you the pretty pictures, essentially!

The frame, made entirely in Germany, is copper plated and it's built up with a Schmolke Carbon handlebar, seatpost and saddle. Schmolke provides the 45mm-deep rims for the carbon clincher wheels while the hubs are from Tune.

A SRAM Red/Force eTap AXS groupset provides wireless shifting. 

The complete bike has a claimed weight of 9.0kg (size medium). It'll set you back €8,499, which is about £7,300.

Also, looks like printed wax then lost wax casting from the Vimeo, so not quite as exciting as first thought. But still a great looking bike!

Those pictures all have the stench of render about them, would love to see some real images.

 Stunning finish, would love to have a go on one.

They went to all that effort but couldn't integrate the hydraulic hoses into the frame?

Looks like it would flex like mad if you put the hammer down.

More seriously, how is the frame actually made? The headline says "printed steel bike" so you think, wow, a entire frame made by 3D printing! Then you read the frame is copper plated. So they printed it then plated it??? And the text doesn't mention anything about printing.

3D printed lugs by the look of things.

Yes, brazed tube construction with 3D printed lugs/junctions. Seems like the complete head tube and top tube/seat stay junction, down to where it actually splits into two stays, is 3D printed. The  joint on the drive side is there for a Gates drive commuter model.

All looks rather lovely, especially in that copper-plated finish.

A velodrome field test – and it doesn't look like either a track or cyclocross bike!

Personally, I'd be a tad worried by the amount stress on those curved 'seatstays'...

I hope the copper doesn't turn green after a while.

They'll have put a clearcoat over it for sure.  Else, bring on the polish and elbow grease.

As the components are really light, the frame must be very heavy for an all-up 9kg weight. Looks amazing though.
