Get a hub motor

[Lowell]

That's because most people don't need or want your motor. Notice how there were zero replies to my 1000ft climb post.

Give me a break you guys will never make any motors.

Dont be too sure volcanobreath... :wink:

Im actually glad my ex partners used old magnets and did not glue them on properly. I'm also glad that Ken did not use the recomended 25 amp fuse for his fat ass without gearing the project accordingly for his fat ass hill climb.He told me that he wanted to go 30 mph on the flats with no hills.Ol fat ass took it on his own to be a show off before he tested the gearing for his fat ass..
glad I got out of that business... :Who has the video of his funky fender dragging as well ? :lol:

It's good to know that you freely admit that your motor has such a narrow performance envelope.

It was the first production motor that went out with out my inpection. I demanded that I inspect and test Kens motor but that did not happen because Ken started to deal directly with ex partners and the partnership imeaditly failed before Ken got his motor.
Miles has a different version that was sold after I was no longer involved with PlanatRyder as well. So I gess I did never have a product.Just a dozen prototypes that all work well.

It's good that you freely admit that you never had a production motor. I HOPE this means you'll stop sniping from the reeds about how terrible everyone else's production motor is compared to your prototype.

Prototypes are a dime a dozen & if you want to compare prototypes I'm sure real world motor manufacturer's could trot out a few dozen prototypes that could blow away anything you care to imagine. Since prototypes while intriguing are completely unattainable, they are essentially ebike porn. Like some playboy centerfold, a pretty face & a hot rotor that's fun to drool over but it's the accessible girl next door that'll give me a ride.

YOU can ride your Hoe next store for all I care.

-+++++++++++++++++ Give me a break you guys will never make any motors.

Do you really think you're the only one here who can make a motor? Short of kits I played with as a kid, the first motor I made from scratch was some 10-13 years ago. Used a board, three nails, a glass test tube and some thick copper wire. It worked nicely, and it's also the first motor I managed to blow up trying to make it go faster.

To bad with all that work that stator is less efficient than a $10. Auto stator.

Show me a $10 auto stator that will slide onto a freehub...

That shows everyone that there is no interest in in what YOU had to say. A better market may be in off road dirt bikes with 5 to 10 kw of power."Ebikes" already has a tarnished name from all the whimpy smoke producing products that have sprung up in the last 5 years that were over priced.

Or it could be because nobody except you has volcano sized hills to climb on their ebikes. What was your 0-100ft time and mph again? Oh wait, my 'whimpy' :lol: hub motor is past 100ft before you even reach 70ft. Guess there's no point in you trying all the way to 100ft...

While I didn't try pedaling, I doubt it would make much difference. Was your 5 second to 70ft time with pedaling?

Piss into the wind already.

How about you just answer the question instead of resorting to childish insults. This is YOUR thread, disc motor vs 20lb hub motor. My 20lb hub motor will walk all over your disc motor, time to speed, time to distance, top speed. Your disc motor gets better gas mileage, I'll give it that.

 

[EbikeMaui]

 

[Lowell]

So your disc motor should reach 100ft in around 6 seconds. Not bad, but still no match for an X5 hub. I'm going to retest my bike with a lighter rider and see what kind of difference it makes. I would expect to see low 4 second 100ft times at over 30mph from dropping 30lbs.

Especially since you have a couple of aluminum posts in the way... :lol:


Hey, Randy's bike did a good job up to 70 feet!

Who knows what happened to the remaining thirty feet, but I'd say the glass is 70% full... optimisim being a virtue and all that.

Personally, I'll take the good gas milage, but a little speed ain't all bad.


To nobody in particular: Maybe it's just me... but whenever I see negative personal comments, I equate them to weakness in rationale.

:?

Yeah unless I unscrew the foot pegs, pedaling is kind of a semi circular affair. The single speed gear gives 15mph at a comfortable cadence so pedaling at WOT gives less than 2 seconds of assist. :lol:

Gas mileage is definitely not bad though, as I rode 67.3km today on 1837Wh, MaxS 87km/h, AvgS 42km/h. Lots of stop and go in rush hour, full throttle racing cars, and some back road cruising to a sport bike hangout.

If one has a strong argument, the facts speak for themselves. Resorting to emotionally charged mud flinging is a sure sign of weakness. Which is unfortunate as Randy's design has technical merrit, it just has the wrong PR man.

The C-lyte hub motor simulator is here..

http://www.ebikes.ca/simulator/

This gives pretty accurate (at the higher end of the speed range) performance figures. Scroll to the bottom of the page for a detailed description of their "home-spun" dyno and its' limitations.

I believe that Lowell is running a 5303 @ ~96V in a 26" wheel (?)

Hey Lowell, what size tire are you running in that monster?

-OR-

What round is it?

[Stevil_Knevil]

Output Power, Torque and RPM:
Voltage Constant: 70 RPM/VDC. Torque Constant: 1.20" lbs/amp. Max Motor Current: 300 A/1min. Weight: 22 Lbs. Dia. 8". Output: 15HP Max. 6HP Cont. Voltage: 24-48 VDC.

Is there any kind of simulator for the B&S PMAC motor that we can simply plug-in different voltages, battery chemistries and wheel diameters (or gearing) available online to help us evaluate the performance of these motors?

X503 in a 26" wheel, 76 NiMH 2D cells in series which is 105v off the charger and high 90's for most of the cycle. Tire is a 26x2.30"

The specs so far are:

top speed 57mph
4.25% grade 48mph
8% grade 45mph
10% grade 40mph
0-100ft 4.5 seconds at 28mph
40 mile range at moderate speeds.

Randy: Can you show another example of an Etek size motor on a bicycle besides the insane-a-cycle? While fast, that bike doesn't look like the sort of motor installation most people would want. The owner even says himself that he would have used an X5 hub had it been available at the time.

I have not seen detailed specs for the Crystalyte hub motors posted anywhere. Maybe someone else can chime in.

This seems to be the best tool to evaluate the real world output of hub motors.
