With two little ones ready to hit the road it was time to kit them out with some wheels.
Took a bit of playing with BikeCAD to model them, with the chainstays, down and top tubes turned off. The single fat driveside seatstay was joined to the head and the non-driveside removed with a zero diameter. The lefty fork is just toggled on in the Fork section.
I even printed out some blank drawings for the girls to colour in to choose their own colours, but the results were somewhat inconclusive. So we went for throw-it-on-the-ground toughness with a robust powder coat finish in non-identical twin paint jobs.
