Budget depending you might want to look at large commercial and industrial drone motors. Most are under the 60mm mark yet can still provide a lot of power but you pay for it with higher costs and a lower RPM/v of around 80-180.
Brands you might want to check out are Tiger Motor, KDE Direct, Neu Motors [Outrunners], Hacker Motor, Lumenier (T-Motor re-labeled?), Cobra Motors or Dualsky possibly.
