'The more safety equipment you have on, the more likely you are to get injured.' While the source of material isn't readily at hand, the general information is documented. A while back, one of the Scandinavian countries passed a bike helmet regulation, Holland if I'm not mistaken. The...

Haven't posted in a while, so figured some contribution was in order. Started getting complacent about riding position by dropping my heel off the back of the peddle. Having large calves the stretching felt good. Started getting this pain, just in front of the heel yet not in the arch of the...

My purpose in asking has more than one facet. It's a good exercise in electronic comprehension, or standing under in my case. Vtubes were the first electronic components, serving the same functions solid state are used for today. Yes they are antiquated for the consumer market, though...

In an effort to expose any potential problem, the top of a small channel on the casing has been removed. This is a 54V battery pack that came with an Aventon Level. Lavender 18650 cells, in a plastic retaining cage, sheet metal connections. Small gauge wires are for charging. Have yet to...

'It's all just a witchhunt, there is no such thing as a pedophile, it's all in your head, must be a conspiracy theory'~ Dauntless Ya, we've all heard the gas lighting before. Maybe you should get an appointment with the eye doctor, that's assuming your not more than just a soft pedo supporter...

Still confused by the 'word games'? CNN WTF is wrong with you, "Assault on women" ARE YOU F'n RETARDED. He is charged with CHILD SEX TRAFFICKING, he's another Gary Glitter. You dumb bastards still think Heather O'Rourke died something other than being sodomized, it was a RUPTURED INTESTINE...

Modern day street lights and rigid stoplights, try to avoid 90deg support angles. May get some mechanical advantage by off setting the power cable from perpendicular to the acting force. While you may not want to hear dramatic redesign, why not route power from the brake side. Better yet...

Let's start where the rubber meets the road, tire pressure is key to an efficient setup: http://www.dorkypantsr.us/bike-tire-pressure-calculator.html Allow me to translate why 'fat tires' are not practical for such a build. It's been tried by another member, and I can't find the post, but 'fat...

Didn't know exactly where to post this very informative release by Applied Science https://youtu.be/Z228xymQYho, published recently.

There are better ppl to respond than me, though you've overlooked some basics. The only thing restricting the motor voltage, is it's insulation. I doubt you want to go through the trouble of using a Mega-ohm meter, but it uses much higher voltage. Current will be restricted by heat capacitance...

Proper tire pressure will be the easiest improvement to handling/braking. Don't skimp on the tires, Flat Protection Strips(fps) are worth the convenience, even if it doubles tire cost. Added weight will require higher pressures, confirm pressure rating before purchase...

I'm of the impression a rotory engine would be used, due to efficiency of designs. Primary drawbacks for Wankel designs, high exhaust temps and narrow band of efficient RPM. Heat transfer at altitude shouldn't be a problem, and the hybrid system would easily be 'tuned' for max efficiency RPM...

amberwolf, you're certainly one of the best on the board. I think an agreement can be seen in the shift of eff at high RPM. Thank you for posting data to back your position. Happy New Year
