-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’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.

The Inspiration

The Explor is Enigma’s fully bespoke titanium adventure frame, handcrafted in-house in Sussex for riders who want maximum control, customisation, and confidence when riding beyond the tarmac. Previously offered as a ready to ride model, the Explor has evolved into a Signature-only platform, allowing every frame to be tailored precisely to the rider and their intended use.

Designed around a flat-bar-specific geometry, the Explor prioritises stability, comfort, and control, particularly when carrying equipment or riding over rough terrain. It’s an ideal choice for extended adventure riding, remote routes, and multi-day journeys where reliability and handling matter more than outright speed.

Built to be adaptable, robust, and beautifully finished, the Explor represents the pinnacle of Enigma’s adventure range. Riders looking for a complete, ready to ride alternative with similar intent may also consider the Escape, while the Explor remains the ultimate custom solution for those heading further afield.

Our Signature frames are true one-offs—handcrafted to order in Sussex, England.

Built entirely in-house, we have complete control over every stage of production, from expert design and precision frame building to meticulous finishing, painting, and final assembly. Every frame undergoes rigorous quality checks at each step, ensuring it not only meets but surpasses our exacting standards—earning the prestigious Enigma logo.

We take immense pride in our craftsmanship, our dedicated team, and the fact that we are one of the few workshops in the world producing truly bespoke, handcrafted titanium frames.

Every frame bearing the Signature logo is a testament to our commitment to world-class British frame building, proudly made in Sussex.

The Details

The Explor is crafted from premium Grade 9 (3Al/2.5V) titanium, delivering a balance of durability, comfort, and long-term resilience across demanding terrain. Its flat-bar geometry features an extended top tube to enhance stability and control, particularly when riding loaded or navigating technical ground.

With generous tyre clearance up to 55mm (700c), a UDH-compatible dropout for improved drivetrain alignment, and a laser-cut bridge for added strength, the Explor is engineered for serious adventure use. A CNC-machined 44mm head tube ensures precise steering, while the T47 bottom bracket provides durability and broad drivetrain compatibility. Custom-manipulated stays improve compliance, maintaining comfort and control over long distances.

Internal cable routing keeps the frame clean and protected, while multiple mounting points allow for extensive customisation depending on equipment requirements. Bespoke finishes and optional fittings ensure each Explor frame is built to meet the exact demands of its rider.
