Its the older kit with the big battery. All 3 are 250w setups (swytch, bafang front drive, bbso1.) I rode this same swytch kit on a katu loaded up for camping up a mountain. I suspect it will do fine hauling our 3yo around town. Want to convert the longtail to mid drive but mostly out of boredom.
Wow impressive fleet indeed! Interested to know how the swytch kit handles the weight and stuff. Which battery are you using? :)
