I’ll start by stating that I am incredibly frustrated right now since I just kicked this thing 4 miles to get home…
Today was probably my fifth ride ever on my Dual Raptor. Both belts broke. One snapped off and the other had all its teeth completely worn down, leaving me stranded. This was the first ride since replacing another broken belt, making 3 broken belts in only 2 rides.
It’s 50° F where I am and there are tiny rocks everywhere. I don’t think those two factors are unique at all to where I am, but perhaps this is vastly different to the environment that Enertion is testing these things in. I have tiny rocks in the gears after every ride. I actually pull over every 15 minutes or so and pop out little rocks with my car keys, that’s how easily it happens.
I own a Yuneec E-GO that i’ve ridden about 50 miles a week for the past 2 years or so. It’s on the original belt. The only issue I had with that board was the ECU (brain part) start to come loose on the board and they replaced it for free. The E-GO has a plastic cover that protects the gears and belt from rocks entering.
I’ve ridden the E-GO all over the USA, from NYC to San Diego, from 40°-100°F…never an issues besides the small one I mentioned.
The wheels and pulleys on my Raptor are all slightly off-balance, so the belt tension fluctuates throughout the wheels’ revolution. Everything is aligned and tightened to what I believe is the best tolerances physically possible, I don’t think the issue has to do with belt tension, alignment, or any other user related issue. I inspected everything after the belts failed again and nothing has moved.
I’m considering TWO options:
Sell the board and get/build a dual hub motor. No more issues with belts, would give me a lower center of balance that I’m missing, higher top speed and less torque which I’d be happy with.
Get new wheels/gears from Enertion to fix the belt tension issue, build a shroud to prevent rocks from getting in the gears (not sure how I’d do this by myself), buy belts in bulk and take them and tools along with me on every ride??
Curious what everyone’s thoughts are since you are likely much more calm and level headed than me right now
