These cylindrical brushed DC gearmotors are available in a wide range of gear ratios. The gearmotors all have the same 25 mm diameter body and 4 mm diameter gearbox output shaft, so it is generally easy to swap one version for another if your design requirements change (though the length of the gearbox tends to increase with the gear ratio).
