I've been through the Instruction Manual, no reference to the crankset or the BB. The best way is to pull the crankset off, remove the old BB and either read the specs off the label (if it has one) or measure the BB shell on the frame and the spindle width end-to-end, and then order/buy the equivalent Shimano un-26

Silly question though, do you have the appropriate tools ? Crank puller, BB tools etc. ?

If not, will be cheaper and easier to have an LBS do it for you.

The tools will cost more than the bike does, just buy a new one.
