A collaboration of cutting-edge technology and companies, anthropometry, and years of experience has led to the unveiling of the new Robot Bike Co. R160 mountain bike frame – designed and manufactured in the UK with partner companies Altair, HiETA Technologies and Renishaw using metal additive manufacturing (3D printing).
A great design freedom has been achieved through the development of a unique construction using titanium lugs, proprietary carbon fibre components and tubing and a double lap joint bonding concept. Through the experience of the partner companies each frame can be tailored to a customer’s individual measurements or specifications, with the added benefit that the frame can be constantly improved as new technologies emerge, as the production process is not constrained by a mould.
The new frame concept was developed by the Robot Bike Co. which was founded by Ben Farmer, Ed Haythornthwaite, Andy Hawkins and Ben Robarts-Arnold in 2013. Robot Bike have a clear mission… to make the best mountain bike frames possible.
Each of the partners is a leader in its own technology field, and the frame design and engineering are therefore grounded in years of experience in demanding sectors such as aerospace, automotive and F1. The suspension design has been developed and tailored for Robot Bike Co. by Dave Weagle, one of the world’s foremost suspension designers, who has a proven track record developing original and class-leading suspension designs for mountain bikes.
HiETA is a specialist additive manufacturing development and project engineering company based in the Bristol and Bath Science Park. With 25 specialist engineers it covers product design, manufacturing readiness and project management services from conceptual design and process development through to early stage manufacturing support, providing its clients and users with the process and facilitating the delivery of innovative products from concept through to end product and commercialisation.
Mike Adams CEO of HiETA says: “One of the great aspirations of additive manufacturing has always been ‘mass customisation’. Leading this project has allowed us to see integration of all the elements – a great new frame design, the use of state of the art software tools for optimisation and automation, the flexibility of the manufacturing process itself and effective collaboration between our partners is a great advert for the technologies and the South West of England showcasing that the aspiration is becoming a reality.”
Maximising product performance
Simulation specialists, Altair, was made responsible for the optimisation of the bike’s additively manufactured connecters. Using solidThinking Inspire, Altair was able to maximise the benefit of additive manufacturing by identifying where material in the connectors could be removed to save weight and reduce part count without compromising performance. These engineering techniques are commonly used throughout the automotive and aerospace industries to maximise product performance but are equally valuable to bike manufacturers.
Paul Kirkham, Team Leader at Altair’s Bristol office says: “This has been a very interesting and exciting project to be involved with. Additive manufacturing is the perfect partner for design optimisation techniques as it allows us to produce components and systems that are far closer to the ideal balance of weight and performance. Robot Bike Co. now have a design that will offer its customer a bike that is truly innovative and unique.”
Renishaw is a world leader in dimensional metrology, spectroscopy and healthcare, applying its expertise to improve operational efficiencies in a vast range of industries and applications, from aerospace and renewable energy to dentistry and brain surgery. It is also the UK’s only manufacturer of metal additive manufacturing systems.
Marc Saunders, Director – Global Solutions Centres for Renishaw, says: “We have been delighted to lend our expertise in additive manufacturing, machining and metrology to deliver a high quality bike frame from an initial design concept. This typifies the approach that we are taking with our Solutions Centres, where we are working closely with our customers to create designs that maximise the production and lifetime benefits that can be gained from using an additive manufacturing process.”
It doesn’t matter how good a frame is if it doesn’t fit the rider, and this is where Robot Bike Co. sees the weakness in the current market offerings. Says RBC’s Ed Haythornthwaite: “If you are trying to produce the very best frame it makes no sense to then only offer it in a small number of sizes when the people you are selling it to come in all shapes and sizes. Think of Robot Bike Co. as the Savile Row of the bike world.”
The retail price will be around £4395 with a lead time of 4 weeks, and the frames will be available to order from June 2016.
