What is your total load (you+complete bike weight), with and without passenger?
bike around 110kg i guess . not sure because its not done and i go on a weight later. ill let you know. my weight and passanger around 140-150kg.
What is wheel OD:
overall diameter is 1595mm. ich checked it yesterday because set up CA for speed sensor.
battery voltage:
voltage is fully charged 88,2V @ 21s lipo. 4,2V NEC pouch cells with 35Ah each in 21s/2p first. later 1p more to upgrate from 70-105Ah.
and no load rpm or speed?
no load speed i didnt check yet. amps around 9-10A which is normal i read for the 10kw motor and installed tire.
Also, is the area you ride very flat or do you have hilly terrain?
china is flat here in my area like most girls breast. no crazy hills or mountains here.
I ask because these are important considerations in how far you can push a system for hard launches. Every start from a full stop begins at 0% efficiency, which means 100% heat, and at full throttle only current limiting can help you get to 50% efficiency prior to 50% of top speed.
i understand why you ask and i dont wanna launch like an idiot every time i stand on a red light. i get gthis controller because my 100A test controller let me take off really good and quiet. so i think the much more powerful kelly should be even better and not 5 times worse, which ut is now.
most time i am going very slowly and carefully here with energy safing starts and smooth rides with using the regen to 95% to complete stop at red lights and max speeds around 45-50km/h.
but i didnt buy a 650$ controller to get 5 times worse performance than my 80-100$ testcontroller. thats why i TEST the bike before with a cheap controller. mske sure everything is fine and performance it like i expect it.
BUT IF I WANT LAUNCH FAST SOMETIMES, THAN I WANT THE THING TAKE OFF LIKE HELL AND LET ME PEE MY LITTLE PaNTS!
A motor that is unstressed can be pushed with far higher current limits than an identical motor seeing heavier loads of weight and/or hills. Take it from a guy who weighs 120kg and lives in a mountainous area, yet still has the fastest electric bicycle in the world that can power right up scary steep mountain roads.
