ISEN is built upon the award winning heritage of UK custom frame builders Hartley Cycles and Talbot Frameworks. Allowing us to combine hand crafted elements with cutting edge frame building technologies, so we can 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. We’ve designed and built bikes for 100’s of riders, so you know if we spec something, we did because it’s the best part available for your bike.

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. 

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.
