Review on Electric Bike Conversion Kit - Voilamart 26" Rear Wheel, 36V 500W Motor, Intelligent Controller And PAS System For Road Bikes by Timothy Hughes

I put this on a 3 wheeled bike(2 wheels in front and one in back) and I didn't attach the PAS(pedal assist system). I have this battery (Orihat E-Bike Lithium Ion Battery with USB Port Electric Bike Battery Conversion Kit (36V12A) powering it.It is very, very weak at best. Even without me on the bike, when I twist the throttle, it does start to go but, I can hold the bike back with the gentlest pressure. Is it only designed for pedal assist? Even if it IS only designed for pedal assist, I rode it and pedaled the bike but, when I twist the throttle, I can feel and hear it engage but it is still very, very, very weak at best and it won't even keep you going, even on smooth pavement with no incline. It just slows down to nothing where I have to pedal it again. I am thinking it must be either defective or something is wrong because I have read other reviews of this and it sounds like it is strong. from other reviews and the description, I would assume that, when I have pedaled up to an achieved speed *say 10mph) it would at least keep that speed on flat, smooth asphalt. Not even close. It immediately slows all the way down until I have to pedal again. I DO know it is working because I can hear it and I can slightly feel it pushing but, man, is it ever slight!The second issue, which is really irrelevant if I can't even get this thing working properly, is that I don't want or need speed. I want more low end torque from the start. I realize that it wouldn't be much and that you will have to assist it but, it should at least try. With me on the bike and the throttle engaged, it engages but, won't even move on flat, smooth, ground. When I assist with pedaling, it isn't even helping.BTW, Battery was FULLY charged when I did these tests.So does anyone else know if this is only pedal assist and also, even if it IS pedal assist only, does this sounds like it is not working correctly?
