There are Road bike (thin tyres - performance); Mountain bike (fat tyres, for rugged terrain); Hybrid bike (both road and rugged) and folding bike (transportability). There are many many bike shops in Singapore nowadays. They ranged from a couple of hundreds to ten thousand bucks. Some of the shops listed are great ones. Buy a copy of "SPIN" magazine, and you get more of them. If folding bike, try DigiNexx at Lavendar Street. It is famous for the folding bike, Brompton and others. Good luck
might not want to check out the one at tanglin. can't remember the name but it's roughly next to the st regis service apartments. the prices are exorbitant and according to my brother who's a cyclist, they are charging way more than other shops. checked it out myself and it's true.
Soon Watt is the agent for Orbea and Seven. If your friend is looking for customised Titanium bicycle, you can trust Soon Watt folks to do a good job in sizing the right bike. Seven bicycle rocks ! I do not have any experience on carbon bikes and Orbea manufactures mostly carbon bicycles. They have other brands which I couldn't recall. Reasonable pricing and negotiable. I think it's better you ask your friend which brand he likes, so many to choose from, Trek, Specialised, Cannondale.Orbea, Seven, Yeti, Intense,Scott,GT, Giant,Ibis etc...and also his budget and riding preference, off road or road etc...Just like photography...so many options.
