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. Our set frame sizes at 1cm increments will work very well for the majority of people but there is also a full custom geometry option (extra charge) should the set size not work for you.
Please see our sizing / geometry page
Each Eikon is handmade to order in our Sussex workshop which gives us complete control over the whole process from start to finish. This means every frame can be tuned to the riders’ specific needs, whether it be custom frame geometry, tyre clearance, cable routing, eyelets, frame finish and more. For full bike purchases almost any specification is possible so if you have something in mind for your new bike build, just let us know and we can make it happen.
You can buy a frame, frameset of full bike. If you purchase a complete bike, it will be supplied fully assembled although a small amount of assembly may be required if the bike is shipped via a courier service. We can build a bike using components supplied by customers, please get in touch to discuss options and prices.
To get started call, email or book a workshop visit online via our website. We will discuss your riding style, your objectives and targets as well as considering any existing bike fitting data that you may have. This information will enable us to create a precise picture of just what you are looking for.
Alternatively speak to one of our chosen cycle retail partners to guide you through the process, all carefully selected for the expertise, facilities and service they provide.
Once the design and specification are complete and signed off, we will request a deposit of £1000 to hold your production slot. Once the deposit has been made, your bike will then be added to our workshop build list. It’s at this point that we will collate all of your chosen build parts for assembly.
Please note, if you’re intending to pay the full amount through a cycle scheme then your deposit will be refunded once we’ve processed your voucher, normally upon handover of your bike or frameset.
Our current lead time is between 60 – 90 Days. For a painted finish please add an additional 30-45 days.
We work with all the major Ride to Work schemes. However a small surcharge may apply depending on the particular scheme. We work with the following schemes:

Frame Buying Options
Handmade frames built to perfection by the Enigma team here in our Sussex workshop. Every Signature frame is meticulously crafted to exacting standards using the finest hand selected materials and is designed to deliver exceptional performance combined with an aesthetic that is classic, beautiful and ‘British’.
Eikon
Made in collaboration with REYNOLDS TECHNOLOGY, one of the oldest and most respected British cycling brands, we are proud to introduce the ‘EIKON’. The name of this beautiful frame pays tribute to the iconic Reynolds brand and the EIKON is designed for maximum sustainability using as many frame components and parts as possible sourced within the UK to minimize the carbon footprint of production and supply. The frame featured includes a stunning custom paint scheme in Reynolds colours of green and gold.
EIKON is a high-performance design for fast paced road riding and the frame is exquisitely crafted from a full set of Reynolds 3AL 2.5V internally butted titanium tubes. Lighter, faster, stronger, EIKON features a fully integrated cockpit option for a super-clean and very modern aesthetic that still retains the beautifully classic lines so typical of Enigma designs. Meticulously engineered EIKON delivers stunning performance combined with a wonderfully compliant ride and the frame itself offers a considerable weight saving when compared to many other titanium frames.
Built from start to finish in Enigma’s Sussex workshop with every process from initial design, tube selection, hand tube mitering, frame construction and final finish all carried out under one roof, the EIKON frame is as British as ‘fish and chips’. A world class, high performance, sustainable frame proudly made in the UK.
