Hej p0pa…patience is not your style, hmmm?
Well…let’s look how intrigued you are…
A single speed Strida has a 100 (physical) teeth beltwheel.
Dual speed Stridas have an 80 teeth wheel - and a virtual one with 132 teeth.
The three speed EVO has a 100 t beltwheel and two virtual ones - with 79 and 126 t.
Correct and comprehensible so far?
An alternative drive could use the 80 teeth wheel - and might have 114,4 and 143,2 virtual teeth.
Above numbers can tell the drive’s name
