We view all our riders as individuals and as such all our stock geometries are unisex in design – offering 11 finely tuned stock sizes from 50cm to 60cm, with the additional option of a full custom design and build (+£300).
Because every Eikon frame is made to order here in our Sussex workshop, we have complete control from start to finish. This allows us to control every step of production, and allows you to fine tune your Eikon your way. From custom geometry through to bespoke finishes and more. So if a stock geometry frame doesn’t work for you, we’ll make you one that does, and with careful consideration on components we can further customise every build to ensure the fit is perfect.
We feel that having a frame that fits you perfectly is a critical part of the process. We have over 20 years of bike fitting experience and data to call upon to ensure your riding position is absolute pinpoint. You can make an appointment here for a fitting. No obligation.
Alternatively you can send us any fit data you have or if you have a bike that fits you perfectly, let us know and we can go from there.
Further information on our sizing and frame geometry can be found here.
Opting for an individually crafted frame presents the benefit of total customisation, tailored specifically to match your distinctive style and riding preferences. This flexibility enables the meticulous adjustment of each frame to cater to riders' specific needs, encompassing personalised frame geometry, customised cable routing, the addition of extra eyelets, and the option for unique frame finishes, including bespoke paint designs. Virtually anything is within the realm of possibility.
When considering complete bike purchases, the range of achievable specifications is extensive. If you have a specific vision for your upcoming bike build, just let us know, and we can turn your ideas into reality.
Step 1. Get in touch:
Call, email, or book a visit online by clicking here .
Alternatively, reach out to your local Enigma dealer, who will guide you through the process.
Step 2. Discussion:
To get started, please complete our
This form gathers essential details such as:
-Your personal information (name, address, contact details)
-Riding style
-Bike fit data (if known)
-Objectives and targets
If you don't yet have bike fit data, don’t worry—we can still move forward and gather that information later. Once we have this information, we’ll prepare a CAD drawing of your frame and start discussing your bike’s specifications, including geometry, finish, and components. We will also give you a price based on your preferences.
Step 3. Deposit:
If you're happy to proceed with your order, we will request a deposit of £1000 to confirm your place in the queue and move forward with the build process.
Step 4. Final Sign-Off:
We will send a final copy of your CAD drawing, a mock-up of your finished frame, and our Build Form for your approval. Once signed, your order will proceed directly to the workshop. At this stage, no changes or amendments can be made without incurring additional costs.
We’re currently averaging 60 days from confirmation to handover for raw frames. If you've opted for custom geometry or paint, please allow up to 30 additional days to account for tubing procurement and finishing.
For full bike builds, we’ll be sourcing and preparing components while your frame is in production, ensuring a smooth transition to assembly once it's ready.
Throughout the process, we’ll provide key milestone updates to keep you informed. Please note that custom paintwork may extend the timeline slightly
When your Enigma is ready for handover, we’ll request payment of the remaining balance. We accept all major debit and credit cards and partner with leading Ride to Work schemes, as detailed below. Please note that some schemes may include a surcharge due to higher commission rates.
To streamline the process, we kindly ask you to confirm your preferred payment method when placing your order, including whether you plan to use a Ride to Work scheme. If you’re paying the full amount through a cycle scheme, your deposit will be refunded once we’ve received the funds from the voucher company.

The Inspiration
The EIKON is more than just a beautiful addition to our lineup—it represents the perfect fusion of tradition and innovation, brought to life through our collaboration with Reynolds Technology. This model pays homage to Reynolds' rich legacy while embracing the future of sustainable, high-performance cycling.
Designed with a focus on environmental responsibility, the EIKON is crafted using as many UK-sourced components as possible, reducing its carbon footprint while upholding the highest standards of British craftsmanship.
With a frame that embodies technical prowess, outstanding performance, and sustainability, the EIKON delivers speed, strength, and lightweight efficiency in one seamless package. A true reflection of Enigma’s commitment to excellence, this is a bike built to ride with pride and purpose.
Faster, Stronger, Lighter
The Details
The EIKON redefines performance with its exceptional compliance, stiffness, and reduced weight, making it a standout in its class. Weighing in at just 1350g for a 55cm frame, it offers a significant weight advantage over its titanium counterparts, without compromising strength or ride quality.
Designed with clean aesthetics and cutting-edge engineering, the EIKON features an optional fully integrated cockpit, giving it a sleek, cable-free profile while maintaining Enigma’s signature timeless elegance. The T47 bottom bracket allows for hidden cable routing to the rear stay, improving both function and lateral stiffness.
To enhance both strength-to-weight and stiffness-to-weight ratios, the EIKON incorporates Reynolds 3D-printed dropouts—a feature that not only improves performance but also minimizes material waste by using an additive manufacturing process instead of traditional machining. The result? A frame that is faster, stronger, and lighter, delivering an unparalleled ride experience where precision meets innovation.
Key Features:

Precision Titanium Craftsmanship
Handcrafted in England using Reynolds Gr9 Ti 3AL 2.5V cold-worked, mandrel-butted tubing, the EIKON balances weight savings with exceptional durability. Dual-pass micro-TIG welding ensures unmatched strength and longevity, making this a bike built for a lifetime of performance.

Advanced Engineering & Performance
The EIKON features a custom-machined T47 bottom bracket and 44mm head tube for maximized power transfer and stability on every ride. Internal cable routing comes as standard, with the option for a fully integrated Enve/Chris King cockpit, providing a seamless, aerodynamic look without sacrificing practicality.

Sustainability & Innovation
From its Reynolds 3D-printed dropouts—which minimize waste while optimizing strength—to its UK-sourced components, the EIKON reflects our commitment to environmentally responsible production. Every frame is crafted to order, ensuring minimal excess material usage while delivering a bike as unique as its rider.
