hey i have a trek roscoe 8. im looking into buying a bafang kit for it. and wondering what kit i need. im a heavier rider, 220 pounds and live in a very hilly area. looking to commute on it with about 1500ft of climbing on the way home. im leaning towards the bbshd motor and wanting the biggest battery i can fit in the frame triangle. if you could send me a link to the kit i need from your website i would really appreciate it and buy from you instead of amazon.
