How Do You Rate These Hubs From Crystalyte Europe....

[The Mighty Volt]

http://shop.crystalyte-europe.com/home.php?cat=250&sort=orderby&sort_direction=0&page=2

I have around €500 to spend, including shipping, from Europe to Ireland.....I was hoping to buy a HUB, preferably rear, to mate to a 48v 20Ah Cammy LifeP04, and a smaller one to mate to a 36v 20Ah battery of the same make.

I would be grateful for all suggestions. Thanks.

Not sure what you are hunting for. Ebikes-ca has a simulator on their website that may be helpfull.

In the US, a popular motor has been the 408, which goes about 32 kph when used with 36v lifepo4. Niether of the batteries is very suitable for use with a 5304. the x5 motors are usually mated with 35 amp controllers, and the motor will draw too many amps for that type of battery in that size. 30 ah would do it.

For us to be more helpfull, we need to know what you expect to do, speed, distance, how much weight, etc.

Hi Dogman, thanks as ever for your feedback.

I weigh 200lbs, I am planning o fit TWO hubs, one front and one rear.

I prefer the front to rear to generate more power, with the front acting a sort of auxiliary, just to get me rolling.

It is my belief, perhaps erroneous, that two batteries and two hubs means that each hub is, potentially, doing half the work, or less than all the work, thus reducing the potential for damage and wear.

I am not looking for a really high top speed, I am looking more for pulling power, torque, and an ability to pull over broken ground as well as tarmac.

30mph would be plenty for me, I do not need strong acceleration either. Low-Down power and solid cruising is more my thing.

I have a budget of around €650 USD.

Thanks again.

If the motors would be used simultaneously, like one throttle controlls both, I'd be inclined to use two identical motors. That way one motor wouldn't be just pulling the other. On the other hand, using them independently, a strong motor on the back, and a gear motor that freewheels on the front makes sense to me. Mostly you'd use the big motor, letting the front freewheel. Then when you need the extra tourqe to climb a hill, or start up, kick in the geared motor.
So mabye a fast motor on the back, like a 407 at 48v, and then a bafang or something like it up front. If you use two direct drive motors, the one you are not using will create resistance, and also heat up, even when not powered.

So you'd have about 800 watts on the 407 all the time, and mabye 350 watts on the bafang when you need to get up a hill, or have more traction. Since the bafang would get used a lot less, a smaller battery could be used for it. If the main motor broke, or ran out of power, you could continue on the other motor.

I emailed the company, and they never emailed back. Poor.

Once again, ES comes out ahead for feedback and sales.

Thanks for your hints, Dogman.

I doubt anybody has two motors and controllers for 500 euros including international shipping.

Well, HightekBikes just sorted me out with one of their sensorless hubs, with all the trimmings, for €202, USPS, posted this morning. OKay, its a bit of a skewed example in that I was given a very generous reduction as I am overseas.

That leaves €298 for me to find someone who will do a similar deal on a rear hub...... and lookey here ......http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=330394226295

Worth it, you reckon

Cheers!

Looks good to me. Euros are worth more than I realized too.

Do you have personal experience of the 408/4011 combo kit Dogman?

Is there a specific controller you think would work best mated with that model of Hub?

Thanks. 8)

No I don't. The Aotema hub is similar to a 407, so on a dual setup I'd be inclined to run it in 408 mode with a normal controller. I'm assuming it would be just a matter of hooking up the correct phase wires. Start another thread on the dual winding hub, or do a search

To run the dual winding controller on both ( one or the other at a flip of a switch) requires the clyte controller designed to switch from one winding to the other.
But you may be able to still switch back and forth by plugging and unplugging different wires to the motor.

You know what, I am starting to think that asking Terry from HighTekBikes to keep me an AETOMA rear might be the best bet yet. All of these options are swarming my head!!

I think I will settle for him putting on a single rear gear, just to get me out of trouble in case my batteries fail or something. Sensorless just appeals to me more.

Cheers.

I run a 408/4012. You won't notice much torque diffrence between the two speeds at the same voltage. Honestly, my 9C has more torque at the same voltage.
Where the 4011 or 4012 shines is at increased voltages. At as low as 55 volts, the 4012 carries my 185 pound self over just about anything I ask it to.

There is a dedicated controller for these motors. its only 20 Amp max, though. very Animic.

the only thing that makes it diffrent from other controllers is a TPDT (tripple pole, double throw) switch. the switch has a 20 amp limit, but any switch would work. currently, I switch mine by changing the plug

Thanks for that fella. I dont think its worth my time then, Max voltage I will be putting out is the surface-charge 55 or so that my Duct-Tape 48'r generates. It is sounding more and more like an Aetoma all the time for me!!
