a bosch will triple it you can get 300% boost 350 on the newer motors. bigger motors weight more and take bigger batteries.
I can climb this hill on my bosch. I can just do it on our e tandem. I can do 10 to 12mph on a 15% in with only the second level of assist. I can only do 300 to 400 watts and that gets me up 17% hills at 10mph. the hill with lights is 16% and the steep one is over 20% I want to check it again today. its 1200 feet of climbing in 1.5 miles to get to it and up it.
