well lets see, the bike is a cheap walmart bike around 40lbs and Im about 140... add a tool box and batteries a front basket and rear rack and maybe were at another 20lbs in parts. far from the max rider weight they advertise.
If you read previous posts I mention i ride the bike med hard.. that doesnt mean Im flooring it all the time when i ride nor from a dead start..i pedal assist the motor cuz i like my legs moving.. Im in manhattan...fairly flat minimal hills.. not to hard not to light...i want the batteries to last me.. maybe my expectations were high in range possibly... i mean how much range should i expect from a 16ah battery? I get at least 18mi before it starts to get to a point where I start heading back to base... and averages about 15-20ish mph but i probably ride around 15mph.
Today i went back to check things out and the throttle was getting no juice. I replaced the charred blue phase wire and nothing happened. I swapped in this 2nd controller I got (same seller, same kit... they sent me whole new kit when I mentioned the first throttle died) nothing worked.
Now if you ask me in the sequence of power i feel like theres an issue right now getting power from controller to throttle. Right... Battery goes to controller... 36v runs through the on/off switch back into the controller and then that distributes it to hub based on throttle value. AND also 5v should run up to the throttle for signal
Well right now it wouldnt even light up...like it wasnt getting power from the controller.. i couldnt even test the throttle on the bike for signal value because it wasnt powered. So i brought it home and powered it again with 3 AA batteries... i got .8v at rest and 4.2v at WOT
only one wire has melted...and only at the disconnect joint... obviously can neither confirm nor deny anything internally in controller or hub
sequence started standard...unbox hub..install all parts, plug together and ride... was fine for a few weeks..
first throttle died... similar event...started cutting out i assumed it was throttle.. died in a day... very quick... twisting and letting throw rip it back to zero made it come back...then no juice...
i test throttle per ebike.ca and incorrect values as per previous posts... new throttle/kit arrives... i install new throttle, plug in battery and off we go... 1 week later cutting out... i check wires to make sure all is good...nothing noticeable...
a day later even more cutting out in short stretches and so i head back to the unit as the throttle dies...this time the on/off switch works and built in battery meter still shows lights n colors
3rd throttle comes in... i install, nothing noticeable about other wiring or phase connection... and off we go.. as per post it acted up... one minute perfectly fine...i park the bike to drop off the food and I come out 2 min later to take off and no throttle response...like wtf... i jump off...open up the box..nothing smells weird, nothing looks weird... disconnect battery to get more access to wires and free space... check throttle cable to see if it loose and nothing bad... plug everything back together...still nothing for a few minutes... then all of a sudden it starts to kick back on... after this I try to finish my last couple orders... running only half throttle... somtimes cuts out at 1/2... sometimes right off the line it was an issue... nothing consistent that lead me to believe it might be heavy load from a stand stlll, or uphill (which there really arent hills in NYC) barely inclines..
my bike stays in a storage locker everyday.. i remove the battery and charge at home daily.
