Trying to "scoop" air into the hole will do almost nothing as the effective fan blade is too small. Instead and very effective with outrunners is a straight radial centrifugal fan blade like used on car alternators. There are even some sold for RC outrunners. The way it works is the centrifugal fan ...

Since you've paid attention to detail cell voltages, how much out of balance is typical? If it's small, then you can generally just bulk charge and occasionally take them off to check the details. Since the only risk of out of balance conditions is over-charging or over-discharging your pack, your ...

ySQZXUsIqJ8 Just to show you guys what this hill is about, I made a clip with other hub motorised bikes for comparison, maybe its easier to see how tough it is for a hub motor in this particular terrain. I was actually a bit surprised that they did not handle it... It also shows how much effective ...

The real problem is the size of the wheel you're running the hubmotor in. Hubmotors ALWAYS perform better and run cooler in a smaller diameter wheel, and your MXUS is no exception. ie I run a 3kw rated hubbie in a 10" scooter wheel with an OD of about 16", the smallest profile 10" scooter tire I cou...

The best bike theft deterrent is to treat them the same way horse thieves were treated a century and a half ago...string them up.

Exactly, be a good ambassador of the cause to promote the most efficient land transportation man has created, and police aren't going to mess with you. OTOH, if you're a menace to other users of multi-use byways, then (and I think most others here will agree), you don't deserve the privilege of owni...

If there's no gear reduction in the shaft drive, you'll need a gear reduction from the motor to the input end of the shaft...somewhere in the neighborhood of a 3:1 reduction is my off the cuff guess. There is somewhere between 3:1 and 4:1 reduction in the rear shaft drive. That was one of the first...

You won't get it until you build your own, but the satisfaction of building your own primary transportation with absolute reliability is hard to beat. No ready built ebike can offer that. Plus their performance in a word " sucks ". Add in that's it's relatively simple to built for performance levels...

20wh/mile is a nice benchmark, but 100wh/mile or more is just too much fun.

As far as giving up one smoke belcher for another, I've got no interest. My car has remained parked for over a year now. I do have something nearly the size of the Indian in the works, but a bit lower and aerodynamically sleeker, and powered by 2 or possibly 3 HubMonsters (whatever it takes to flat...

John, you might be able to embarrass a cruiser, but even with 5 hub monsters, you couldn't touch a zx10r that does 189 mph out of the showroom. 200mph+ with some cheap mods. I loved it but it's impractical for long road trips. 0-100mph sure it will. I have no interest in going faster until we get a...

Bicycles that drag are a drag, is all. John rides motorcycles, and has different priorities. Any bike with a motor is technically a motorcycle, and anything you ride on with 2 inline wheels is technically a bicycle. If you want to talk about arbitrary legal definitions then it depends on where you ...

Lets say you have a 20 mile commute using regen in the best conditions for it to be used, what is the max voltage input 1 can expect back into the battery ? 5% - 10% max ? Are there any negative aspects to using regen , as far as wear and tear on the motor, magnets, controller, battery ? "Best cond...

The day my wife gets to "allow" me to do anything is the day I say "next" after she hits the curb. I do agree with "happy wife = happy life", but it takes happy me as well, and that means doing whatever I want. The key is finding one who's perfect happy with you doing whatever you want. As far as gi...

Thank goodness we don't get that kind of aggressive behavior from cagers down here. There's enough idiots to avoid already, Yeah, no kidding. http://www.ticotimes.net/2016/12/16/costa-rica-ranks-one-worlds-dangerous-countries-drivers Nice try again Chalo. The stats creating the rankings are skewed ...

Sorry, not a chance I am using ATF!! I've done that before, and the mess it made was diabolical.

It sounds like you didn't seal it properly. OTOH if it caused a motor malfunction I'd like to hear about it.

Thank goodness we don't get that kind of aggressive behavior from cagers down here. There's enough idiots to avoid already, but for the most part they just line up waiting in traffic with plenty of space between for those of us on 2 wheels to safely get around efficiently time-wise. I love passing b...

OTOH, once I'm over the hill I can coast down so I won't need any motor at all anymore, right? :P Guys peak at 17, so you've been on the long downhill side for quite some time. Thank goodness our ebikes make us feel like kids, because I'm 7 years ahead of you down that hill...with plenty of "city m...

What's the true weight of the raw frame? The Amazon listing says 23kgs :shock: , which can't be right since the shipping weight was less. That's definitely not the small square tubing based Enduro like sold by em3ev, which has tons of wasted space in the construction. This one looks cavernous inside...

While he said geared hubbie, don't forget he's done 10 years with lead and a crap brushed motor with many replacements. Take the full step and go with absolute reliability as an upgrade. So what if there's a 5-10lb weight penalty. Compared to his lead anchor there's still a big weight savings to enj...

Biggest 20" rim I've ever seen.

What's the brand and source for your Enduro frame? What is the weight of the frame with swingarm? It looks significantly different than the one I have in some good ways...primarily that it's a monocoque structure instead of square tubing based, and I like that for the space savings. To me tubing jus...
