A'r un mor gryf â'u brwdfrydedd dros eu chwaraeon mae eu cariad dwfn at y wlad maen nhw wedi'i mabwysiadu, a'u hymdrechion i ddod â chyfoeth a swyddi i ardal Machynlleth. Y brawd hynaf, Dan, yw crëwr Red Bull Hardline, "y ras i lawr anoddaf yn y byd" sydd bellach wedi dathlu ei 8fed flwyddyn yn Ninas Mawddwy, yn ogystal â Pharc Beiciau Dyfi sy'n denu dros 500 o feicwyr bob wythnos o bob cwr o'r DU. Pan ddechreuodd y teulu Atherton Bikes, gan gynhyrchu beiciau mynydd o ansawdd uchel sy'n ffitio'n berffaith, y peth naturiol i'w wneud oedd lleoli eu cyfleuster ym Machynlleth.
Their passion for their sport is matched by a deep love for their adopted homeland and a drive to bring wealth and employment to the Machynlleth area. Oldest brother Dan is the creator of Red Bull Hardline “the world’s hardest downhill race” which is now in its 8thyear at Dinas Mawddwy as well as Dyfi Bike Park which draws over 500 riders a week from all over the UK. When the family started Atherton Bikes, manufacturing high-quality, perfect-fit mountain bikes it was only natural that they would base their facility in Machynlleth.
