When Brompton wanted to develop an onboard toolkit for their folding bicycles, they turned to British industrial design firm Goodwin Hartshorn.
"We took advantage of the bike's foldability to create a toolkit which fits inside the frame," the firm writes. "This protects it from theft and from the elements."
"The kit includes all the tools necessary for most roadside repairs in a compact, lightweight unit. Perhaps the most innovative features of the kit are the space-saving double-ended driver bits and the unique tyre levers. These not only make removing tyres substantially easier, but also incorporate 10 and 12mm spanners.
"
Brompton retails these for $100.
