go-one Evo-R-

go-one Evo R Daniel Fenn, at this time European champion in the class of fully faired recumbent bikes, approached the company Beyss with the idea of modifying the go-one Evolution, to make it leaner, smaller and lighter. The aim was a velomobile for every day use, which was clearly optimised on races end records.

The result was the go-one Evo-R-. Without rear-suspension and hardtop it weighs only approx. 20kg and is, due to carbon fiber / Kevlar – honeycomb building technique, incredibly stiff! The rapid go-one Evo-R- can, at extra charge, be ordered with rear-suspension. Due to a carbon rear fork (ball bearings) and a DT Swiss air shock the weight will thus only be increased by approximately 1kg.

In spite of being optimised on races and records, the go-one Evolution is entirely suited for daily use. It is reduced to the necessary, but of universal use and built robustly.

go-one Evo R

Due to good capacity utilization with building the Evo-K- and the Evo-Ks- and due to lower demand for the older models, this go one-variant is no longer produced.


The extremely stiff vehicle chassis is built in carbon fiber-honeycomb technique. We apply high quality fibres, gel-coats and epoxy resins only. Additionally, only high-end bike bicycle components will be assembled, such as Ultegra cranks, Sram XX derailleurs 10-gear, Double Tap Shifter, Terracycle chain idler 23 tooth, low-maintenance S.A. drum brakes, vertebral column friendly carbon seat (550g as a supporting part),carbonboom, hardtop, hardened canopy, hardened hardtop windows, chain ring 61 tooth (normal riders), bigger ones on request, Ultegra rear sprockets 12/27, Joysticksteering on both sides,

We guarantee a weight of the above vehicle of 20kg without Hardtop (1,4kg). Different colors are possible, however may result in higher weight. Further weight reduction is possible, as low as 17 Kg, on request and extra charge. The vehicle will be adjusted individually to the customer.
Further special wishes are possible on request.

different Versions:

This version is identical with the version mentioned above, but there is no honeycomb technique used in the sides of the Chasssis.

This version is made from Carbonfiber, with Aluminiumboom, Aluminiumrearfork, Standard Switch-, Brake- and Suspensionparts. The go-one Evo-R- Carbon with Joysticksteering and ready to drive is offered in white, also available as a kit.
