Bikesales4u is run by Peter Deussen, former export sales manager at Planet X.
Valdora of Arizona produce road and triathlon bikes and frames.
Prices for complete bikes start at £1,899 for the PHX-1 SRAM Rival build, to £2,699 for the PHX-1 SRAM Red build.
Valdora source frames from China, made in their own-designed moulds.
The brand is being sold consumer direct in the UK but Deussen's company is the appointed distributor for Europe.
Deussen said Valdora was the first brand he's bringing in to the UK:
"Next will be a legendary single speed frame builder from the US, plus an established Italian hand-crafted frame manufacturer. The objective is to have a small, select , non competing range of highly respected brands not commonly found here in the UK."
