savage cranks

hello everyone,
i got my first unicycle at christmas. its a 24 savage.
There is a problem however, i di drops and stuffs on it and bent one of the cranks really bad. the place where i bought it from cant find a replacement for the one.
Can i just buy a pair of cotterless cranks from UDC?
If so, which ones would u recommend.

p.s. i just want this unicycle for cruising so are 145-150 the right crank length?


Anything down to 125mm is ideal, the shorter the better really… for cruising around.
