I bought another folding bicycle in March this year, which is the third one. Let me put down some words about the three bicycles.
1) A Raleigh 20" bought from Amazon UK during a 3 week stint there in Jun 2009 at £147.99. Used it for my commute there riding around The Drop Inn Hotel @ Wilmslow Road, Manchester. I can't say much about this bike as I only rode it during my stay there, and [accidently] sold it on ebay to someone in Singapore.
2) A Polygon Urbano 3.0 bought last year to actually try out bicycle commute using folding bicycle. I like its lower price yet comes with rear rack and fenders.
3) A Tern Link C7 bought in March this year so that whole family can go further out for a ride together. Indeed, from Toa Payoh, we have ridden to Bishan Park numerous times and ECP twice. Five year old son is not cycling yet, just using his balancing bike.
