CNC-machined frames

Hi, I am Simon.
Curiosity and the passion for technical challenges, together with my long-time experience in engineering, are my driving force behind innovative concepts. My high demand for relentless function and an aesthetic design, render my bikes with an exclusive character.
Since 2018, I design and manufacture ACTOFIVE bicycle frames, made in Germany.


Your Style – Your Setup

What if you could approach your perfect setup step by step?
ADJUSTABLE RIDE° (AR°) allows you to setup the geometry according to your preferences. Choose your Base Setup or purchase AR°- Kit´s.



Redefining the status quo

The deep-feeling HPP suspension gives massive traction and confidence on fast, rough trails while not missing trailbike attitudes through a well-balanced package.

>> 29 Zoll, HIGH PIVOT (HPP) suspension
>> 135 or 145 mm travel for Trail- and Enduro riding
>> CNC-machined from soild blocks of 7075 T6 aluminum

    Each component is manufactured here in Dresden under the roof of METZNER Engineering GmbH by using state-of-the-art CNC manufacturing equipment and measuring systems. The processing time of the four main part takes around 22 hours while machining 38 Kg of 7075-T6 aluminum. Chips as well as larger residual parts are recycled.


    ACTOFIVE Frames are precision manufactured, carefully joined and conscientiously assembled. The verification of safety and durability is performed according to the EFBE TRI-TEST® consisting of fatigue tests, maximum load tests and overload test in various load cases.


    The warranty is 5 years from date of purchase and covers manufacturing defects only.
    Costs for returns are covered for customers within the EU.


    The P-Train will be fabricated in a limited edition and is available worldwide.

    Custom finish2021-06-28T11:44:37+02:00

    Be individual! The front triangle and the rear end can be anodized before joining. Find suggestions on social media or on NEWSBLOG.
    Please note: Anodized colors may vary slightly.

    Complete builds2020-12-03T06:24:10+01:00

    Not at the moment. Please ask your local bike shop. Only some selected components are available.
    Ask for a set-price.


    With 1,78m and 80cm inseam, my personal bike has size S2. Please note: Due to its steep seat angle, the bike feels relatively compact.

    Living a vision is worth the long nights at the workshop. 
The effort that goes into each frame is more than 8 hours just for the manual work, including bonding and assembly.
