I've had good luck printing PLA with my E3D hot end, even with a 0.25mm nozzle. What cooling solution are you using?

I have 2 E3D hotends, I tried probably 10 different rolls of PLA, and I could not reliably print any of them, they would both exhibit basically the same issue, filament would stop extruding then if you were lucky it would dump the filament that stalled leaving a void followed by too much extrusion.
There is a piece on my blog about my experience, including several examples.
I know there are many people claiming to print PLA reliably with them, I personally have not successfully done so, I have a JHead, it prints PLA perfectly, so I use that.

20mph, up to 260lb rider - up hills, down hills, hard acceleration, hard braking. Nylon does it all with ease.

PLA dreams of being able to do that.

There are some bad links on that site, at the bottom under products.

There certainly are. Thank you for the catch...

I was one of the first to print from the trimmer line and gave the link to the one on Amazon and I am shocked that it has the strength to act as a gear in such
a product. How long has your gears been used in this product and after checking for long term wear, how are they holding up? I am surprised that they stand
up to such a harsh environment. They would be great for Garage door opener gears and other products also if they can hold up under the conditions you are
subjecting them to.

Nylon will do whatever, It don't care. The only problem I'm having with it is keeping it dry.... Nylon is a serious filament for serious needs, and from what I saw during rich-rap's tear down of a PLA part VS a Nylon part its even difficult to get it to delaminate (he was tearing apart a single wall vase, and had to get pliers out for it). If you can keep it dry it will do whatever you need it to.

I've shipped 38 of them after we tested them for about 30 ride hours. Prior to shipping nylon, I made them in ABS that I vacuum bagged in BJB epoxy after printing.

By now I'm guessing the units have 500+ hours on them and not a single failure yet.

The stuff is incredibly strong. I print at65% infill! but we've tested all the way down to 30 and they still work.

Harsh environment indeed. My customers are excellent at testing (read: breaking) things.

What kind of range can one expect from the maximum range board you sell? Assume 260 pound rider and terrain like Culver City or Hollywood proper (not the hills)?

The high capacity lithium board would get you around 10-12 miles, if not a little more, on mostly flat ground.

Nice!!! Sounds like a killer board. I stopped skating back in 1989. Tore my ACL in a pool just dorking around. Didn't stretch and hopped off the board and popped that ligament clean without any cartilage damage. Never had it re-attached.

How long does it take to charge to full capacity once fully drained?
