<p>with a shtty bike a shtty lock will do, just make sure you lock it to something to prevent opportunist thieving. If you have a good bike get a better lock (doesn’t have to be a top notch lock). no-one rides to class or anything, it’s all far too close with stairs, ups and downs. But riding in the city is perfectly fine (just make sure you have good street sense). there are also bike paths along the river which i take all the time. Biking saves $2 when you would otherwise use the subway, these add up over the months, it’s also the fastest way to get around the city in the day time, comparable to the subway quicker than a cab and miles ahead of the bus.</p>
