WELCOME

ACTOFIVE Cycles is dedicated to providing high-quality mountain bike frames and components that are designed and manufactured in Germany by using a unique CNC manufacturing technique developed in-house. With a focus on technical innovation and aesthetic design, owner Simon Metzner brings his expertise as a mechanical engineer and mountain biker to create bikes with an exclusive character. Since 2018, Actofive has developed multiple frame platforms and components that cater to various types of mountain biking, from fast and fun XC riding to the demanding challenges of the Enduro World Series.

CNC MACHINED

Each component is meticulously manufactured in our state-of-the-art facility in Dresden, Germany, in collaboration with our sibling company METZNER Engineering GmbH. We utilize cutting-edge CNC manufacturing equipment and precise measuring systems to ensure the utmost precision and quality. The main parts of our components undergo approximately 22 hours of processing time, during which 38 Kg of 7075-T6 aluminium is machined to perfection. We are committed to sustainability, and recycle both the chips and larger residual parts produced during the machining process.

Once the machining process is complete, we dedicate a further eight hours of manual work, including bonding and finishing, for each individual frame. This meticulous attention to detail guarantees that every frame meets our high standards of excellence and creates an exclusive character to our bikes.

EXQUISITE CRAFTMANSHIP

Producing an ACTOFIVE frame is a labor of love. With so much dedication and precision required, we’ve set a limit to maintain the highest standards. From the initial design to the final assembly, every step is carefully executed, resulting in a masterpiece that is as unique as you are.

CUSTOMIZE YOUR CRANKSET!The SIGNATURE X is the heart of your drivetrain. From FEM-optimized weight, different spindle lengths to custom hardware colors, every detail is now tailored to your performance needs and aesthetic vision.So, What’s new?1. SIGNATURE X-SL (-50g) AS LIGHTWEIGHT OPTIONThrough meticulous FEA (Finite Element Analysis), we successfully removed an additional 50g of mass from the crank arms by utilizing deeper, more aggressive machining in the backside pocket of the crank arms. The front side is exactly the same.2. COLOR PROGRAMM FOR THE HARDWARETo complement the raw, silver- or black anodized finish of the crank arms, We now offer the hardware in six distinct colors.3. NEW SPINDLE OPTIONSThe SIGNATURE X system continues to utilize our modular spindle design, making it compatible across almost all disciplines from Gravel to DH. You can choose from three spindle lengths:SHORT: For Gravel and All-Road applications. Q-Factor: 161,5mmLONG: For standard MTB (Boost) configurations. Chain line (CL): 51mm, Q-Factor: 168mmEXTRA LONG: For DH and Super-Boost frames. Chain line (CL): 55mm, Q-Factor: 176mm Check our website for more info.Which combination would you choose?#rideactofive #cncporn #cncmachining #localproduction #madeingermany

What a way to wrap up 2025. It was super exciting to step into the world of 32-inch wheels with the I-TRAIN. Being at the forefront of this new development has been a highlight of the year, and the ride feel is something you just have to experience. We´re looking forward to seeing where this "32-inch thing" goes in 2026 and how this segment continues to grow.Cheers to a big 2025 and an even bigger 2026! 🥂#32inchbike #32inch #actofive #yourstyleyoursetup #rideactofive

We couldn’t have planned it better: our last build before the holidays turned out to be this stunning red frame, perfectly timed for the first snow. What’s your take on the color? Is it a "yes" or a "hell yes"?Wishing you all a relaxed holiday season and some quality time on (or off) the trails. #actofive #yourstyleyoursetup #rideactofive #mtbtech #mtblife #mtblove

The I-TRAIN 32 is here! - We developed the I-TRAIN 32 as a no-compromise 32-inch machine. The geometry has been dialed in 100% for the 32-inch wheels, but it still carries the DNA of the 29-inch I-TRAIN. This means it’s not just a straight-up XC-racer; it`s a true Trail Bike.All the rider contact points have been kept analogues to the 29-inch I-TRAIN. To pull this off, we engineered and manufactured an optional, proprietary stem from the ground up.➤ No-compromise 32-inch Trail Bike - Ready to Shred!➤ 120-140mm front and rear suspension➤ All travel settings 32″ or Mullet (32” front / 29” rear)➤ Fine-tuned geometry and kinematics➤ Proprietary low-rise stem➤ All rider contact points are carried over analogous to the 29-inch I-TRAIN➤ We offer two frame sizes S2 and S3➤ Reach Numbers Size S2: 455 mm Real Reach / 485 mm Effective (Felt) Reach➤ Reach Numbers Size S3: 495 mm Real Reach / 525 mm Effective (Felt) Reach➤ Head Angle: 65°/ Seat Angle: 77.5°/ Chainstay: 458.5 mm/ BB: 333 mmMore information on our website.#32inchbike #32inch #actofive #yourstyleyoursetup #rideactofive #mtbtech #mtblife #mtblove #lifebehindbars #enduromtb #sendit #partyinthewoods #cncbike #cncporn #cncmachining #localproduction #madeingermany #madeindresden #metznerengineering
