Urwahn announced the Platzhirsch, a new commuter e-bike with their trademark swoopy frame design. This is also the first 3D printed bike from the brand – and it’s actually made of CroMo steel. Integrated LED lights brighten things up front and rear, while pedal assist comes via a Mahle electronic rear hub.

The wild-looking frame shape isn’t new, but other Urwahn models use brazed lug and tube construction with specially shaped teardrop chromoly steel tubing and cast lugs. The new version uses 3D printed lugs which are brazed to the same teardrop tubing. The ‘3D printed’ lugs are produced using Selective Laser Melting which allowed the company to shorten the production time, and not be restricted by any part geometries since changes to the overall design can be made quickly via computer.

The no-seat-tube design is made to provide flex and a smooth ride quality. Complete bike weight clocks in at a quoted 11.4kg (size M).

Another other important change is the addition of a Mahle ebikemotion rear hub, providing 250 watts of assist, 40NM of torque, and up-to-25km/h assist speed. A 250Wh battery is integrated into the down tube, providing up to 80km of range.

A Gates carbon drive system comes standard, eliminating pesky routine maintenance. Tektro HD-R hydraulic flat mount brakes handle stopping duties.

Integrated front and rear lights come courtesy of LightSKIN.

The Platzhirsch rolls on 700c wheels with Continental Grand Prix Urban 35mm tires.

The Platzhirsch is available to order now, for €3,999. Urwahn is also currently offering a €500 pre-order discount.

    28 years later and here is a steel version of Kestrel 500sci! In all fairness, this does look rather sleek but am disappointed with this use of 3D-printing technology. It’s a manufacturing process that offers nearly limitless opportunities with design yet what we see here could just as easily be a monocoque carbon frame. Maybe there is an intricate lattice work inside the tubes that allows for the skin of each tube to be extremely thin, don’t know. I just don’t understand using a process for the sake of using it when this frame could have just as easily been welded up from straight-gauge or hydroformed tubing.

      Why are you assuming that a tube is not ideal? Just because 3D printing opens up the potential for intricate lattice work doesn’t mean that there is a benefit. From a weight/stiffness proposition, hollow tubing is the best solution. It put material where the largest forces are.

      3D printing can be used for two reasons, making otherwise difficult to make parts or saving money/time.

    That’s impressively light for an ebike. I’d like to see a cross section of the tubing and a ride review. If 3D printing actually makes sense economically, then that process has come a long way. I wish all bikes could move past derailleur systems, if only they could get past the friction issues.

    Scrolling down through the article and I saw “LightSKIN” and I thought that was the name for the color of the bike. Kind of a bad brand name when taken out of context.

    What?! How?!?! This thing is 3D printed steel?!?! That’s a huge print at an amazing price?!?! Something doesn’t add up!?!? There is a HUGE story here if it really is 3D printed.

      Sorry, we should have made it more clear in the article – only the lugs are 3D printed, not the entire frame. Those lugs are then brazed into steel tubes with a perfectly shaped stepped joint which is what gives the frame such a smooth look after finishing.
