Crystalyte Cannon?

Hi folks, this is my first post. I've been lurking around while trying to learn enough to spec out an electric bike for my 18 mile commute.
I saw this Crystalyte Cannon hub motor over at Texas Electric Bikes. Very little information on the web site, so I called them up and they said that the Cannon Motors were more powerful than the series 4, but lighter than the X5. He couldn't tell me how many magnets or turns of wire around each one. Shipping weight is listed as 12 pounds, which I am pretty skeptical of.
Has anyone heard anything about these motors?
I also asked about their Lithium batteries, and he said his new batch had arrived and was going through testing. He said they were Lithium Iron batteries, so I guess that means they will be different than the ones that have gotten the favorable reviews here.

Re: Crystalyte Cannon?

I almost bought the 5 series until I realized that they draw so much current at normal bike speeds. Too powerful and too much of an energy hog. I went with a 408 using 72 volts and a 35 amp controller and I cannot see how anyone would want more speed or power than that. You also get great range with four Dewalts.

Yea, I decided that the 5 series was way too heavy at 25 lbs. I ended up ordering the BMC Puma geared hub motor from the same place. Couldn't find any user reports on the Cannon. From what I hear, the Puma develops similar torque to the Crystalyte 5 series from an 8 pound motor, due to the 6 to 1 gear reduction, at the cost of giving up some speed at the top end, and some noise from the nylon gears.
Hey Russ, your article on the Grist web site played a large part in getting me going on this project! (I live across town from you in Des Moines). I like what you innovators are doing with the DeWalt batteries. I am hoping that by the time I am ready to crank up the voltage, the larger a123 cells will be available in some form, but to get my ebike on the road , I am starting out with a 36v 15AH LiPO from the same vendor as my kit.
I'm designing this bike for my commute which is 9.5 miles each way, and starts with a 300 foot hill in either direction. I expect my starter battery will deliver about 430 watt hours, but I can charge at work. I don't have enough data to tell if this battery is going to do the job by itself, but at least the last mile is all down hill! :)

Re: Crystalyte Cannon?

Russ, are you using unmodified Dewalt 36 volt batteries in series? I would like to take advantage of the battery's built-in charger/controller, but lacking any specs wasn't sure how the control circuit would respond to a series arrangement. Also, do you happen to know what current limit the controller imposes on the outgoing circuit?

`Uplink and dugly,
Welcome to our V is for Voltage Community, we're glad both of you are here.
We're also anxious to see more details about the The ultimate Seattle hybrid bike in the Building E-Bikes Collaborative Hand Books
