<p>It is doable if you combine your bike trip with the metrorail(and you can take your bike on board). Take Indian Hill to Foothill and travel west on Foothill til you come upon the Sierra Madre metrorail station. And from there its smooth sailing, errrr I mean railing. Its still a substantial bike ride. Check it out on Googlemaps. There is also a great bike trail that goes south along the 605 freeway from Irwindale all the way to the beach.(the San Gabriel River bike trail)</p>
