Hi,
I'm new here, so hello everyone!
I'm having a major problem with the electric bicycle I purchased 3 and a half months ago; I bought it so I can travel a distance of about 35km, of which approximately 8 are uphill, with a somewhat steep gradient (especially the last few km). It's a 36v, 250w (front hub), 8Ah-battery bicycle that weighs approx. 25kg, I weigh 60kg, and I usually take cargo with me weighing somewhere between 10 and 20kg. So, total weight is about 100/105kg.
It's this one:

Ok, so what's the problem? The problem is that the original motor burnt out at the end of that steep ascent the fifth time I climbed it, then the store replaced it with a new motor that burnt out the first time I climbed it, then they put a new one (always the same model) that also burnt the first time I climbed that hill. So, it's already the 3rd motor that burns, always at the exact same place (right when I get to the top of the hill). I didn't pay for any of the new motors, as it's in the warranty.
I've been using the bike these last days without using the motor (as it's not working), and am thinking of either taking it back to the store for a full refund or trying to find a motor that will not burn when I climb that hill (the bad part about this option is that I will have to pay for the motor). I was thinking maybe a 250w high torque motor (that will reach only about 15km/h instead of 25) or a 500w motor (which I'm not sure will work, as the controller is - I think, as it's not in the manual - only 14 or 15A and the battery is only 8Ah).
So, what do you think? Do you know any 250w motor that is high torque? I have only seen one at a store (this one
Kits Platinium L1 Rubí sin batería ciclotek, kits de conversión eléctricos, motores eléctricos para bicicletas, bicicletas eléctricas - the one that says "alto par", which means high torque in spanish, in the "Elija su tamaño de llanta (platinium)" field, which means "choose your wheel size"), but it says it's for a 20" wheel (mine is 28").
I would really like to find a motor that suits the bike as I like the bike a lot, but if that doesn't happen I'll have to take it back to the store. :/
Thanks!
EDIT: the bike does not have an accelerator, it's only pedal-assisted
