DEVS 301 Zippelin_ development

Traditional motorcycle bodies are not useful. They are ABS formed, are expensive to paint and inflexible when considering our parts need to amend internal dimensions. Our solution is to form a bodyshell by attaching 3d-printed brackets to the frame and then assembling a wireframe that allows stretching fabric around it. The inspiration comes from both the Czech 'Velorex' trikes and Zeppelin dirigibles.

DEVS 701 Ultron_ development

Ultron is a super strong robot with genius intellect, which is the goal of this motorcycle. Its motor has 11kW power and speed up to 150 km/h with unbelievable acceleration. Other advantages are range (battery has capacity of 120 Ah and range to 200 km), ABS and quick charging. Planned to be available for 'Beta' testing from Spring 2023. Please contact us if you wish to be a test rider.

December 2020 - Ongoing

DEVS 601 Alien_ series production

A new higher performance 6-series, the DEVS 601 first defines our upgrade philosophy by customising factory production using 3d printing to fabricate the parts that facilitate the re-engineering of the bike. The goal is on the batteries being recyclable and consumption being so low that you can effectively ride around just from solar power.

DEVS 402 La Boheme_ development

A lighter version moped with 200km range. Conceived together with a brand name 'La Boheme'. It's identity is the idea of a cheap, easy, lifestyle of wandering around and having fun. To make it as affordable as possible, the basic donor bike is a well-tested Honda design from the 1980s and the method of reconstruction goes back to early aircraft designs of the 1920s. The final working prototype is patented and could be homologated for sale at a very affordable price.

DEVS 401 NNN_ concept

A first thought at how to construct a new low-performance DEVS 4-series of mopeds based on the idea of offering slower city speed and range. The final design was going to be a naked bike, but ended up not being naked at all. Hence the name. It should be possible to go 400km on this bike and charge it overnight. Why 400km? We believe 400km is the most anyone would wish to go on a motorbike in a day.

electric cyberscooter
May-September 2020

DEVS 511 Cyberscooter_ concept

The Tesla Cybertruck isn't for quick trips around town. Our idea was to design a matching Cyberscooter that could be carried on its back, and even charged there. This way you can use the advantage of the Cybertruck for long distance trips and the Cyberscooter for the 'last mile' where congestion and parking are problems.

DEVS 506 Cezeta_ development

Project to develop, manufacture and homologate a new upgrade of the Cezeta scooter. The frame, body and brakes to the electronics and instruments were made locally in the Czech Republic for this rebirth. The monocoque frame was redesigned for easier future upgrading.
