quite pricey if you ask me...
i wonder how that hub motor is against ex 5304 hub motor ...
anyone???

Not pricey at all if you compare it to other kits with li-ion batteries, in fact it's couple hundred dollars cheaper.
Be nice if we had more info on the wattage and such.
I have no idea what that motor is.
You should ask Justin.
It might be a brushed motor. It's certainly not anywhere near a 5304 in power.

I think this is the motor Lowell posted pictures of a while back.. not certain of that tho.. lowell ?
Found this on the Ezee motors..

i think said like 400 watts
and they maybe the one used by shwinn
not a bad price looks like it has disk brake and tire! front hub good for a mid size person IMO
but geraed might be the key here making the batts lasting longer -efficiency.\
I was planning on a rear 5304 preferably with like one speed freewheel and if possible disk brakes ( rear atleast for now) for saftey
is the dish off center on the motor the same for different freewheel gear clusters?
thanks guys

Actually it would be safer with a front disc as it contributes most of the breaking power.

ben a strong front brake is no good in the wet, down hill, when turning or on loose gravel. i would pay more to get the back brake discilized. a strong back brake give you confidence when riding cos you know it will always be there. i think its really bad that not all crystalyte motors come with disc's as standard -they need them.

I just installed one of these eZee kits form ebikes.ca. They sell the kit without batteries. They do not sell the motor alone. I have not had a chance to put it through the paces (a little much rain in Seattle recently), but I did take it around the neighborhood.
First impressions:
INSTALL:
-Very easy installation (compared to C-Lyte) no file needed.
MOTOR:
-BLDC with internal gears and freewheel
-16ga wires for motor
-Lighter than 400 series
-Good fit and finish
-180mm brake disk
CONTROLLER ('cop in a box'):
-Has an UPPER voltage cutoff, somewhere between 40V and 60V
-Seems to limit speed also
-bike jerks forward when switching off at the throttle
PERFORMANCE:
-Good out of the box performance using 40V 18650's 12s2p (Sears Craftsman packs x2 ). Hill climbing comparable to 4012 @66V, 20A. -Whirring noise from motor tolerable.
Quick Summary - Good kit for minimal weight hill assistance. Not as easily hot-rodded as C-Lyte kits.

Welcome Mr. Cyote!
Thanks for the report.
That sounds interesting. I didn't know that was geared and brushless.
I might not be too hard to hot rod a bit with a different controller.
I'd love to see some pics of the install and the controller.

Rode the eZee kit to work today in place of my usual 408/4012. VERY SMOOOOOOOOOTH!!!
Some eZee kit Observations ( 40V Li-ion, 200lb rider ):
Max unloaded speed - 22mph
Max speed on level -17mph
Peak Current Draw - 16A (wattsup)
Peak Wattage - 578(wattsup)
Subjective Impressions:
My c-lyte setup does 28mph on level ground, so I was a bit disappointed with 17mph but not surprised considering the lower voltage. power delivery is SO SMOOTH, no cogging/moaning/vibration like 408 under heavy load. The whirring noise form the eZee is hardly noticeable in traffic, and not offensive. I far prefer it to the 408 vibration. When riding unassisted I didn't notice any extra drag and the bike felt much like a regular bike. Hill climbing was comparable to my 4012 but without the 'bike quake' and at half the power consumption.
I'll post some pictures as soon as I figure out how

That's the beauty of geared hub motors, although mine is an older designed motor (also 18 mph), it gave me the same impression.Are you thinking of boosting the battery power in the future?

I love my geared hub motor!
Haven't put my watts up on it yet, but performance is great!
No load speed of 55 kph, and have managed 53 kph with a tail wind.
Power transfer is really smooth from a standing start, all the way up to max speed.
Usually cruise at around 38 kph, and hill climbing ability is great! usually never drop below 25 kph.
Runs at 36v and controller is rated at 15A. Has all the power that I need on my trike.
Getting to be that my DF BB chain drive is not getting much use at all!
Now all I need is a LiPo battery pack for the trike and I'll be in electric heaven ,

What does the controller look like?

Here's a pic of the controller. It uses a PIC 16F73 microcontroller, de-restricting probably involves firmware. The big lytic up in the corner is 63V. I can't read the FET part# without de-soldering the heatsink tabs.
The case is well-sealed with RTV, actually looks like it would survive seattle.
Overall looks well made and solid.

Excellent! We get to see the insides!
It looks like interfacing a different controller (unrestricted) would not be too hard.
Does anyone know if there's a way to read the program code out of a PIC after it's programmed?

ooh! looks like that's a Flash MCU. So a custom made firmware is possible.
Google'd data sheet => http://www.robotstore.com/download/246781.pdf
No clue on reading the installed firmware.

I program these things for a living. Given a good schematic custom firmware is a possibility. Reverse engineering one (without damage) would be a chore.
I'll ask ebikes.ca for a schematic but that's a longshot.

Ditto on the geared motors. I have had a brushed P2a from Brett for 2+years on my Tricruiser. Runs in wet weather OK. Needed to put spacer after 2 yrs to reduce lateral movement on axle! I weigh 230 and corner as hard as possible on my trike! Gears rule!

Does anyone know anything about the 37V 10Ah lithium battery that comes with the eZee hub motor kits from ebikes.ca?
I'm new to this forum...I was very excited to run across it. I've been dreaming about building an electric hybrid bike for years. I'm plotting my move into the market. Thanks!

I don't know about ebikes.ca but apparently members of the ebike forum in Great Britain have a fondness for the ezee models but many were having trouble with the ezee lithium batteries; primarily involving battery life I believe. Their complaints were answered by the ezee chief as follows:
Theres more and you can read it here http://www.pedelecs.co.uk/forum/electric-bicycles/1241-ezee-phylion-li-battery-forum.html
Obviously the power of a concentrated forum of customers played a large role but it seems ezee wants to stand behind its products. I don't know if his largesse extends to the USA batts.
Thanks for the detailed report, Wile E. very interesting.
Do you have the Ezee motor in a 26" wheel? If so, I'm rather surprised at the lack of speed you've found with the Ezee motor: while the rpm is still likely to be rather lower than your crystalyte 4012 with 66V, a similar motor in Ezee Quando/Torq bikes can still do 17mph @37V in only a 20" wheel, and around 22mph in a 700c/28" wheel @37V (equates to around 260rpm at 36V) so if the motor you have is not too different (probably the same one which is said to do 22mph in the Torq 'Trekking') I'd have expected you to get around at least 22mph top speed @40V if your wheels are 26"?
EDIT: Alhough your results are roughly consistent with the 1km/h per V for the motor Lowell posted http://endless-sphere.com/forums/viewtopic.php?f=2&t=2470&p=33360&hilit=geared#p33360 - about 22-24mph no load speed with 36-40V in 26" wheel, the ezee motor simulation on ebikes.ca suggests top speeds of at least 18-21mph (depending on charge level) with only a 36V battery without even pedalling :? .
Is there any possibility that the motor speed has been limited though, for sale/legal use in Canada, perhaps? In the UK, for instance, some Ezee bikes, e.g. Torqs, are sold with limiters for 25km/h or 15mph (legal limit), which must be disconnected to get the full revs from the motor. I'd suggest you ask Justin at ebikes.ca about that, though I'd be surprised if he didn't mention it if it is possible to derestrict. The current limit and peak power you measured are exactly what I'd expect for a 36V battery though.
