We study the uplift of a 4d black hole in 4d Einstein--Maxwell supergravity with a spindle horizon to massive type IIA and 11d supergravity on S4× ℍ3. The solutions exhibit features distinct to the uplift of the same 4d solution to 11d supergravity on an S7. In particular, whereas the orbifold singularities may be removed in the 11d uplift on an S7, they are always present in both of the classes considered here. We compute the free energy of the solutions giving predictions for the free energy of a class of 3d Chern--Simons theories wrapped on a spindle.
