SETTING UP SHOP
It's every man's dream to retire early and pursue his dreams.
Sin shares: "I am looking at the possibilities of doing a bicycling tour business for cyclists who want to explore KL.
"I have two partners who are very keen in this project and gave their personal input on how to formulate packages with interests like historical places and food joints in the city.
"We have positive vibes about this and I do hope it will take off."
Sin has the entire Kuala Lumpur's "secret" cycling pathways on his hand and wants to use this knowledge to
benefit those who want to utilise their bikes in the city without the hassles of getting stuck in traffic.
