I use my bike to office on a daily basis , 4 km one way . There are bike tracks along the way till my office . its pretty safe if you follow all the rules while crossing the signals etc , and stick to the bike track if its available . best way to get some exercise done while commuting. oh yea! i carry my office clothes in my bag and change from my office :P , carry a deo , you will need it . in summer if you go early in the morning the sun isnt that hot .
