    How do I remove this crank (pics inc.)

    I just bought a crank puller to remove and replace the crank on this bike, but it's not the same as my other bike. There is a bolt protruding out that gets in the way of my crank puller! Do I need a specific puller to remove it? Will it affect what type of crankset I can put on? Thanks in advance!

    First, there are several styles of crank pullers, so yes, you need a puller designed to pull that crank. All that being said, that crank you have there is a very common style, and a basic puller will work, no problem.

    As far as what crank you can mount, cranks are matched to bottom brackets, so its not as simple as taking that crank off and putting on a different one.

    +1. Some bottom brackets, like the one pictured, have spindles with external threads on the ends, so the cranks are held on by a nut. Others have spindles with internal threads, so the cranks are held on by a bolt. Once the nut or bolt has been removed, though, the process for crank removal should be the same: Thread the outer part of the crank puller into the crankarm, then use the inner portion of the crank puller to push against the spindle and remove the crank. If your other bike has a BB with internal threads and uses bolts, then the spindle is likely to be shorter in total length than the one pictured. If the spindle in the photo is too long, then to get it "out of the way" of the crank puller, you should need only to back out ("unscrew") the inner portion of the crank puller until you have enough clearance to thread on the outer portion.

    Cranks are indeed matched to bottom brackets. Fortunately, there are only a few types of BBs, so it wouldn't be difficult to find a match. I'm guessing, from the photos, that yours is a square taper, but I can't see well enough to tell for sure.

    Agree it is most likely square taper but different cranksets require different spindle lengths so it is a bit more complicated than finding any crankset with square taper interface.

    Looks like a Sugino "Maxy" crank. A standard 22.0mm puller will work fine.
