Speaking of Spokes……

Perhaps you are wondering about the mechanics behind the bicycle wheel, how spokes work, what lacing patterns can be used and so forth. More likely, perhaps your not. Regardless, here are a few words on the fascinating topic of spokes. The spoked wheel was first conceived by Mr George Cayley who was an early pioneer […]

Buckle up and knuckle down

In order to reduce the weight of a bike it is important to explore tube dimensions such as wall thickness/diameter ratios and length/diameter ratios to determine the best dimensions for the purpose. Looking into this can lead to a somewhat interesting (for some at least) foray into stress analysis and buckling theory. Referring to a […]

Balancing Bikes

It is a surprising fact that even though the bike is 200 years old this year (2017), it is still difficult to explain exactly how it works. It is a case that we know what works and what doesn’t and how to build a really good bike; but not really why. However one thing is […]

Bespoked 2017

Once again this year we were proud to be part of Bespoked the handbuilt bicycle show, a showcase of world-class, hand-made bikes from all over the world……and little local ‘Rodford Built’ with our own sturdy handbuilt style. Highlights from the show included Feather cycles, always quality, August bicycles with their handsome city bike and Sven bikes […]

Food Distribution..by Bicycle.

Great to be able to finally talk about our latest collaboration. We have been working with Fareshare (food redistribution) and Boston Tea Party (Cafe chain). Fareshares wonderful initiative to fight hunger and reduce food waste now has a Rodfordbuilt cargobike to help with their Bristol Logistics. Thanks to Boston tea Party for facilitating the purchase. […]

Looking at Moments for a Moment

We’ve recently been investigating the benefits of different steel sections for our frame parts. Rectangular and square box section are easy to come by and have flat faces which can simplify assembly. The question is – would they be any more or less rigid? To answer this we modelled some comparative parts on a CAD […]

A happy new year starts with 2 layers for protection and longevity.

We have some frames at our powder coaters, its a chance to test the system and work through issues with production. Its a good start to the new year,  we want our bicycles to last, to be handed down the generations…we want them to look good for a long time…which is why we wanted the […]

Fatigue……….yawn

Fatigue failure of a material is always a concern to design engineers because it is difficult to calculate for a given part and therefore presents an unknown risk in the final product. Factors that affect fatigue strength include the material, shape of the part, any defects, corrosion, heat treatment and loading. Fatigue is defined as […]

Introducing Little John (one of our band of merry men)

This is our latest acquisition. The Raglan “Little John” metal working Lathe.This model is the MKII and features a screw cutting gearbox and power cross feed. Built some time in the 1940’s the Little John’s were notable for being at the top end of the hobby sized machines in terms of capacity and ability. The […]
