...If you switch to a different number on the wheel, you'll need to switch to a different shifter.
First must determinate how many speeds my rear shifter can change.
My Freewheel is modified, and real question is what was original, and how much speed my shifter can change? From
L_I_N_K I found, his bike have SunRace MFM-608, 13 - 32T, it seems freewheel.
But I can't shift on smallest cog. You see that there is very small gap between frame and cog. And if I shift chain with hand, it's touching frame (you see frame wear down). Not sure can I repair that only with adjust machine.
So, it seems I have rear 8 speed?(not shifter confirmed!).
All that I am asking to buy correct Cassette. I want to buy that will fit to my shifters, and I don't must buy new shifters
So, I not confirm with shifting on smallest cog that my shifters have 8 speed, and if my bike maybe 7 speed freewheel, and buy 8 speed cassette, that will be problem.
And how much maximum is motor hub speed cog, I must ask seller (Someone said 7). Know is 41.8mm.
