Hi Tony, good to hear you are still well and "Aprilia-ing"
I have been meaning to contact you to see if you have any spare Aprilia Gboxs or parts left. I think i have another damaged cog in mine.as it is getting a little noisy.
I have been running 10s 4p , 14 Ah packs of 18650 for a year or two and these packs are so small and light.
Infact i can get 2 of them (=28Ah) in the battery compartment at once. (Maybe i should try 72v
Do you still have the Optibike ? ..i have messed with a couple of A2B hub drive bikes but they wont dismantle and fit in the car like the Aprilia, so they have gone again. Now i am curently assembling a dual suspension MTB (Specialised FSR) with a 48v , 750W , mid drive (TSDZ2) motor
Infact, i am also measuring up the Aprilia to see if one of these (or the Bafang "Ultra") will replace the whole Aprilia gbox assy if i cannot get a new gearset for it ?
