5kw version motor(USD390) weight is 12.5kg
Could be interesting.

Anyway, get A cro with temperature sensor och at least add it if your version does not have it. That way you know that you will not burn it :)
 
The problem with the cromotor is that it's a single speed unless u go for the schumph drive. Then U have 2 speeds. But theyre $1300 and u need this drive if you want to pedal fast.

I'd go with the crown. What dropout width have you decided on.

If you are serious about getting a cromotor and ready to buy, PM Zombies. He will hook you up. He may even have a custom controller set up for the Cromo. Version 1 aren't available anymore, except maybe used, you will most likely find a V3 but there are V2s out there. I don't know what the diff is between a V2 and V3 cromo, just that both are different than the V1 with slightly more copper fill and an aluminum stator.

If you have a true 4065, you should not be able to go 35-40MPH on 52-58 Volts. Those are the speeds the 4065 would go on say about 80 volts, even 72 volts, the 4065 would be hard pressed to exceed 33MPH wether running 40 or 100 Ah.

well I have a 2.5 schlumph drive and clip in pedals so I can use my hamstrings to pedal and CAN hit 40-41 mph for short bursts....but 35 is easy I can cruise at that....maybe my display is wrong?..I have it set for 25 inch tires....you have any photos of your frame?....I think you should talk to the guys at HPC their prototype frame design is incorrect....just thought of something....I did a drive to a local pup and checked the mileage on mapquest against my display mileage it was the same...so 40 mph IS correct and double checked voltage 58 volts off the charger

When Hyena first switched out the 4065 from the 4080 he was running, on 18s, (75Volts hot off the charger), his 4065 on his fighter topped out around 55Kph or about 32-33MPH on 75 volts. Yah, as you and I know, pedal assisting, provided your gear ratio is tall enough for it, can add around 3MPH to your top speed. Case in point, if I pedaled my ass off in 9th on my bomber when the 5403 was on it, I would see speed around 56MPH, no pedaling, 53MPH. So I know what you mean there. But even with a 26" skinny MTB wheels, your 4065 shouldn't be going any faster than about 28-29MPH on your battery, and figure upto 33MPH or so with pedal assist. Your speeds, especially with the 19MC wheels front and rear, really suggest a 4080 instead of a 4065. Is it possible that HPC mis-labeled their HPC 80 with HPC 65 sticker?

It's not quite $1300, for a high speed 1 to 2.5 Schlumptf drive. Here's what I got from ebikessf.com (Ilia). 117mm BB/ $810, 34T chain ring $66.90, crank arms $30.35, SF tax $79.38. Grand total = $986.63 yes, a lot of money! Plus installation. (needs a special tool rental). almost $1300, I guess? But that gives you a 34T/85T!!!!!! at the flick of the ankle. 85 teeth and it fits the Phasor BB.With a 34 tooth profile. Mines not done yet but I think its the way to go? Hoping to go with a 5 speed cluster in the rear with the Crown set up. We'll see?
 
Yes that's right Allex If you talking to me, my build for the Crown motor is right at around 7 thousand. Your very good. I haven't even messed with MC rim and tire builds yet, although I think that's the way to go at least in the rear (Yamaha Playbike 19 in. Like Korpin) about the same as a 26 in. bike rim but no flats and DOT speed ratings. I've been to Sweden. Love the Swede's! I have friends in Stockholm and Malmo, and in the south I believe Sloevesberg? on the Baltic. Good to hear from you.

Oops, That's not pictures of my crashed bike, that's a picture of my new (old) toy bikes, BMC V2 and V3, 48V 12a. At EbikesSF,com my buddies shop (ilia). Coming soon RELEVANT!! pictures of my new Phasor build, Crown Motor, DP #1 -100v! Also tried to post pics of my wrecked bike. Pretty awful anyhow. Keeps saying image too large. How can that be, when It's not even a video?

Missed the pics earlier, very nice clean geared hub builds. Really clean.

I have decided on a 163mm drop out
 
Ok this old guy figured out how to post at least a couple pictures. Sorry for my ignorance, thanks for your patience. :twisted: :D

To Australia was another 150 odd in shipping then the exchange rate, our tax is 15% so if anything more than 1300. I haven't added it all up.

that could be...speed was 53 mph with 90 volt system and 27" tires so maybe it is a 4080....but 35 mph at 58 volts is no problem can do that for miles..you know the "4065" sticker is not there anymore maybe it got switched somewhere?....thinking of swapping out internals for the newer version if I can get a controller that can handle my batteries in series..

.also,its possible that the heavy motorcycle tires and tubes add momentum like a flywheel...and of course the shinkos are quite smooth and have very little surface contact if you stay on the centerline

I don't think it is. With the heavier wheels/tires, your gyroscope effect will be increased at high speed, but that effects handling/steering more than anything the faster you go. As far as forward momentum goes from fly wheel effect, if there was an effect, ( I'm not 100% sure, but I'm saying there isn't) it would not be enough to explain your speeds quoted at the given volts with that hub motor. Unless HPC did some real funky programming with your controller, I think you have a 4080 and not a 4065.

well like I said above,I can only go 40-41 mph for a short burst..but pedaling at a relaxed rate with full power its around 35-37 mph...I checked mileage on a small trip on mapquest and it matched indicated mileage on didplay and have wheel size set at 25"....HPC was also saying that seems fast for only 58 volts....maybe I should take trip to longer destination and check mileage against mapquest again?...the sticker is no longer on the motor but here it is before I put it on bike...is there that much of a difference between 4080 and 4065?

[quote...is there that much of a difference between 4080 and 4065?][/quote]

Outside dimension wise, there is no difference, its just that the 4080 would have a stator with less winds than the 4065. It would appear that HPC agrees that your bike seems a little fast to be a 4065 on 58 volts, which is probably more like 54-55 volts under load, don't know how much voltage sag you get. This is what I hate about the Crystalyte's measurements now. Back in the day, they had a better way of measuring hub motors. For example, their old coding system was much better. Take the original X5 hub, the 5302- 5305 or more commonly referred to as the 53xx series, the 5 designated the series, the middle two numbers designated the width of the stator and the last number was how many turn winds the stator had. So a 5303 had a 30mm wide 3 turn stator. The 5304 was 30mm wide 4 turn stator. This is also the same for the 5403-5405, the 5 designated the series, 40 designated stator width, and the last digit was for the winds on the stator, for example, my 5404 has a 40mm wide 4 turn stator. Moving on, the newer measurements are now based on either the 36 volt, or 72 volt standard. For example with the 3540 motors, the 35 denotes the width of the stator 35mm, and the 40 denotes potential top speed in KPH at 36 volts with a 26 bicycle wheel and 40Amps. Your 4065 is the same type of rating, except with 72 volts. The 40 denotes a 40mm wide stator and the 65 denotes potential top speed in KPH at 72 volts input. So based on that, your 4065 should be good for about 65 KPH which is about 40MPH at 72 volts with a 26MTB wheel tire combo. Well your going that fast, with a slightly smaller tire and 14-18 volts less depending on voltage sag, I think you could have a 4080.

Definitely a 4080. Someone has stuck the wrong sticker on it. I know, this lack of quality control out of China is unheard of! :lol:

Yah Jay, I find it very unlikely that Korpin's 4065 on 58 volts was faster than your 4065 on 75 volts even though he is running a different wheel and rim than yours at that time. If I recall correctly werent you getting about 60KPH out of your 4065? Seems like I remembered that you got to 55KPH pretty quick on 18s but then it slowed way down and signed off.

Rick
 
Exactly right. 0-50km/hr pretty briskly then winding out to around 55. That's with a little battery sag and a fat 24" wheel.
To get the nominal quoted "65" you'd need a 26" rim with a fully charger "72" battery which is spitting out more like 80v actual.
