DEVS 507 Cezeta_ development

Continuing the Cezeta philosophy of a scooter as a 'car on two wheels', the project's aim is to build a vehicle combining the advantages of both. It means to be fun and cheap like a scooter, but to be also fast and practical like a car. First road-legal prototypes are planned to be available at the end of May 2024.

La Boheme motorcycle
2024 – ONGOING

DEVS 702 La Boheme_ development

Continuation of the custom Type 7 with several improvements from the Type 701: mid-motor for more torque and acceleration, higher voltage for more power (up to 110V) and new body designs based on the theme of a modern Cafe Racer. We are currently seeking investors for this project to finance serial production.

recuperation throttle

Recuperation throttle_ revflex™

Improved version of the idea of a two-way throttle that was first developed for the Cezeta 506 project. This was patented on 23 March 2023 and will be developed through the summer for testing in Autumn.

DEVS dashboard v1.0_ development

A new touchscreen display controlled by an Arduino MCU that CAN communicates to the onboard electronics. As well as showing real time battery information, it can calculate useful parameters like the remaining distance. Follow progress of the project on Youtube and learn how to build your own.

type 701 e-motocycle
2022 – ongoing

DEVS 701 Ultron_ development

The 7-series aims for speed and high performance. 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. A small-series of 5 motorbikes was sold for 'Beta' testing from Spring 2023.

type 301 e-bike

DEVS 403 Zippelin_ development

Traditional motorcycle bodies 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. In this way it could be personalised quite easily with the zip mechanism. The inspiration for this idea comes from both the Czech 'Velorex' trikes and Zeppelin dirigibles.

DEVS 601 Alien_ series production

The 6-series aims for long range and convenient recharging. The first-edition 601 also 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.

electric la boheme concept

DEVS 402_ development

A lighter version moped with 200km range. 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.

electric nnnbike concept

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 have a range of 400km on this bike and charge it overnight. Why 400km? It's about 10 hours charging from a standard AC 230V socket, as is common throughout the country.

electric cyberscooter

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.

cezeta 506 parts

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. It was carefully tuned to be one of the world's fastest scooters.
