The ISEN experience is about more than just a bike, it is the involvement in the production of your bike, channelling your passion and our skills into a machine you will ride for many years to come.

ISEN is built upon the award winning heritage of UK custom frame builders Hartley Cycles and Talbot Frameworks. Allowing us to combine artisanal hand crafted elements with cutting edge frame building technologies to deliver bikes that are at the forefront of frame geometries and are finished to the highest standard. From our custom cable routing to hand finished headbadges everything is meticulously crafted and a result of our experience. Beyond building bikes, we have a serious passion for riding, with a diverse range of riding styles and experience and are heavily involved in the cycling community. We personally test and progress our designs in all conditions from pushing the ultimate crit lean on our local circuits to climbing the most gruelling of summits or taking on the audax you really hope to finish without getting hyperthermia or seeing just how fast we can ride down those stairs. Because all our bikes are made in our workshop, we never stop testing, prototyping and developing our designs. Our bikes are a part of our daily lives and we are always in search of the ultimate riding experience.

We operate as a small highly skilled team who are all involved in every aspect of the production of every frame. It’s a collaboration and we work together to deliver you your dream bike. From the moment you send that first email, make that first call or get in touch via Instagram, you’ll be involved with the team. Each one of us able to help you along your journey from advice on groupsets, keeping you updated on your build schedule or helping you choose the correct frame options. Welcome to the family.

We don’t just ‘design in the UK’; we build every frame here,

from raw materials & tubing to finished bike.

 

Your ISEN frame goes through four unique and specialised stages of production here in our London based workshop from raw materials to a completed frame ready to be dressed with your chosen components. It all begins with the tubes; we don’t believe in building a bike around a specific tubeset, instead we have designed the perfect bikes by selecting from the best tubes, Reynolds, Columbus and Deddaciai offer to produce the ultimate custom blend. Each tube is precision cut on one or our mills, each setup to perform a specific cut to the highest quality. They are integral to our work and are therefore treated with the utmost respect. The accuracy of these titans is key and we could spend hours discussing their individual quirks like old friends.

Once your tubes are cut and sit perfectly in the frame jig your bike is visible for the first time in its most raw form and it’s time to weld. All ISEN frames are welded, we believe this is the best production method, it allows every tube to join together in unison, to become one. This results in one seamless metal frame, to create an optimal balance of flex and rigidity. After the firm grip of the jig has been removed the frame goes through rigorous welding and alignment checks to ensure that every build meets our stringent standards. Bottle bosses, cable guides and headbadges are all seamlessly attached to the frame with silver. This precious metal is used as solder to create the smoothest of transitions and allows us to create some of our signature features. Each of our asymmetric bridges is individually finished to fit your frame, providing both flair and function to with increased stiffness and strength. Your ISEN headbadge is hand formed before becoming the finishing piece, readying your frame for its transformation in our spray booth.

Our award winning paint finish is the final stage in the creation of your ISEN. Carried out in our specialist paint booth we carefully lay down the smoothest signature sick candy fadez and crisp ISEN logos. Every detail of the paintwork is painstakingly applied as multiple layers of custom mixed colour and vinyl masks. Everything you see on the final frame is in paint; there are no stickers or decals. The paint is finished with a high gloss, super hard lacquer providing you with protection for years to come. After leaving the paint booth, every frame is quality checked and given a hand polish to make every surface shine at its brightest.
