My colleagues in TW has these 2 models which i think it's damn cool;

1) http://www.giant-bicycles.com/zh-tw/bikes/...s.1/6452/41891/
2) http://www.giant-bicycles.com/zh-tw/bikes/....4f/7100/41890/

The MR4 can actually go quite a high speed.... As I am riding a road bike, my colleague follows quite close behind.... very cool bike indeed, but only available in Japan and also TW
