A bike park-ready P-TRAIN, built by @rtb_bikes_custombikes .
With 175mm rear and 190mm front travel, this machine is ready to push the limits on any freeride or downhill track.
How do you like the look of a dual crown-equipped P-TRAIN?

BESPOKED 2026 is officially in the books! ⚡️

What an incredible weekend celebrating craftsmanship, engineering, and pure passion for all things cycling. Connecting with this community, sharing our story, and diving deep into technical talks made every minute worth it.

Thank you to everyone who stopped by the booth, inspected our lineup, asked the tough engineering questions, and shared their energy with us.

Big thanks to the @bespoked.cc crew for bringing together the absolute best show in bespoke cycling once again.

A massive thank you to the incredible ACTOFIVE team and supporters - it's your dedication and belief in our engineering vision that made this possible!

Until next time!

A Modular Platform - Our new E-Bike platform integrates a suite of proprietary ACTOFIVE frame technologies to optimize geometry, kinematics, and structural integration without compromise.

Modular-Pivot-Technology (MPT°)

Features an Interchangeable and modifiable main pivot allows fine-tuning geometry, anti-squat and anti-rise.

No-Yoke-Technology (NYT°)

Features a Structural integration of yoke and pivot axle, where forces are transmitted from axle to chain stays by splined shaft connection saves plenty of room for motor / gearbox systems.

Adjustable-Ride-Technology (ART°)

Features Interchangeable and modifiable ART°-elements, allows to adjust geometry and wheel size configurations.

Setup 1: 29” Standard

Setup 2: 29” Long

Setup 3: Mullet (27.5”/29”) Standard

Setup 4: Mullet (27.5”/29”) Long

Setup 5: Super Mullet (29”/32”)

Inside Our E-Bike R&D. ⚡️

Here’s a look behind the curtain of our modular E-Bike platform development:

Engineering at the Core: At its heart, ACTOFIVE is an engineering firm (@metzner_engineering ). Guided by a passion for riding and technical perfection, we craft high-performance frames using in-house technologies refined over years of continuous development.

6 Months of Engineering and Design: The initial design and engineering phase of this modular platform spanned six months -from early conceptual CAD models to a fully validated system layout.

Finite Element Method (FEM): Through advanced FEM analysis, we simulate stress distributions and dynamic loads across complex frame structures. Factoring in real-world riding variables allows us to optimize strength-to-weight ratios while ensuring uncompromised structural integrity.

Physical Mock-up Validation: Spatial mock-ups are an essential bridge between CAD and production. Early 3D-printed prototypes enable us to fine-tune ergonomics, verify seamless manufacturability, and finalize every functional detail before transitioning to CNC machining.

Two worlds, one single interface - Maxon AIR-S x PINION Integration

Integrating both the @maxon_bikedrive AIR-S e-bike system and a non-assisted @pinion.eu gearbox into one chassis is an engineering challenge we couldn't resist. We´ll make it possible to seamlessly run either system within the exact same CNC-machined main frame.

No compromises on geometry, kinematics, or structural integrity - just pure modularity engineered into a single platform.

What if @actofive_cycles made an E-Bike?
Well… @simon.metzner is going to make it happen!!!
The X-TRAIN 🥹🫶🏼
Still in the concept phase.
E-drive or gearbox — the platform is being developed to make both possible.

We’ll be there along the way.

Let’s see where this one goes.🤘🏻

What if ACTOFIVE made an E-Bike Frame?

That's what we had to ask ourselves as electric assistance has undeniably reshaped modern mountain biking.

As bike obsessives and designers, we couldn't ignore this shift - so we engineered a modular, precision-machined CNC platform powered with next-generation electric assistance by the @maxon_bikedrive AIR-S system (Switzerland).

And we haven't forgotten non-assisted riders: we developed the platform to also fit a @pinion.eu gearbox incl. Smart.Shift and belt drive for pure, human-powered adventures. Both systems share the same frame and interface.

It’s been a little quiet on our end lately - and for good reason.

Behind the scenes, we’ve been cooking up something entirely new: endless hours in CAD, running simulations, and pushing our design language into new territory.

We’re not ready to reveal the full picture just yet, but something special is actively taking shape.

Mark your calendars - first reveal on September 1, 2026!
