For something affordable, a used single speed/fixie is pretty easy to maintain. If you are going to be living around some parts of Somerville or commuting a farther distance you probably want to spring for something a bit fancier. There is a free and for sale group on facebook(bikes pop up on there often enough), and I think MIT police still does a bike auction in the fall? If you can't wait for that, Cambridge Used Bicycles is where I got my first one, like /u/thefunk3 suggested.  \r\n\r\n\r\nMake sure that all parts of your bike are secured onto the frame! This got my friends and myself a couple of times - people will take your front wheel, the seat, whatever isn't bolted on (i.e. on a quick release). Make sure that when you use your U-lock it is going through both your frame and your front wheel, or use a u-lock and a cable lock to secure everything together. I personally use [this](https://www.amazon.com/Kryptonite-Kryptolok-Mini-7-Bicycle-7-Inch/dp/B005YPK8R6/ref=sr_1_9?ie=UTF8\u0026amp;qid=1529563103\u0026amp;sr=8-9\u0026amp;keywords=kryptonite+bike+lock), and I find it has just enough room to secure everything(especially with thicker parking meter stems)but I can't recommend anything longer since I've heard people use the extra space to get more torque to break the lock.

If you have quick-release wheels, either replace the skewers with [bolted versions](https://www.amazon.com/Delta-Axlerodz-Bolt-Bicycle-Skewers/dp/B000ACAMKG/ref=pd_lpo_vtph_468_bs_lp_tr_t_1?_encoding=UTF8\u0026amp;psc=1\u0026amp;refRID=9542SBDBN54Q1630JRGR\u0026amp;dpID=31T8KSVETDL\u0026amp;preST=_SX300_QL70_\u0026amp;dpSrc=detail) and/or use a cable to lock the wheels to your U-lock. Note that smaller/more compact U-locks are safer because they're more difficult to cut or break. \r\n\r\nAs long as your bike isn't super valuable (\u0026gt; $1000) and it isn't the easiest one to steal in the vicinity, this should make theft really unlikely.  \r\n\r\nEDIT: Also I recommend replacing your seat post clamp with a bolted version if it is quick release. Seat posts and saddles are annoyingly expensive and it takes one second to steal them if you have a quick release clamp.
