i never had a Adaptto, so i cant really compare. and for 2 years i had only a sweet little kelly for my first ebike.
both are sinewave.
Adaptto is 18fet. Sabvoton is 24fet.
Place for the Big Monster with Cycle Analyst? -> no Question for half that Price the better package
Money is no Problem, dont need a PAS to Setup a "Legal Mode", not enough Place? -> Adaptto is your friend.
