Indeed. I have swapped out the front disc brake for an AVID BB7, the front disc brake kit is actually a rear unit from a normal bike, minor modification would be required to fit a front bracket disc brake kit to the front wheel..

i have also swapped out the crankset, pedals, seat, and added bar-ends to the folding bars - extending the reach a little, making longer rides not so cramped.

genuine strida-centric bits like the plastic headset, belt, wheelset can be had from areaware.com simply email them and they can source these for you, they even have some already instock. Just be aware to not bike-nerd them onto your fake bike details!
