I'd like to make 428 moto chain the standard, because it's cheap and readily available with easy to find driven sprockets. The ID required matches the 58mm of common driven sprockets, and with half inch pitch chain it looks like the minimum tooth count on the drive sprocket needs to be 26t, which doesn't seem to exist. The smallest I found down here was a 37t, which I'm pairing with a 56t on the wheel, both larger than necessary. Another issue is the 3 bolt disc brake mount vs 4 bolt sprockets. I had a machinist mod my drive sprocket to make it a 4 bolt mount.grindz145 wrote:Wow, yeah bicycle chains need not apply... Sick motor and a sick price.
Know of any sprockets that will bolt up?
The low price is just passing along my savings. The factory had a shelf full of motors with built on AL rims that got damaged with no way to fix, so essentially worthless to them. After seeing how much mine was like Farfle's custom motor, I just couldn't resist the price they gave me, so I had them verify that the motor itself was fine, hack off the rims, and put them in a crate.gensem wrote:Really sick price... $389 delivered to Louisiana...
John, whats the motor size?

That's a nice looking motor. When you add more pics and data could you include:
- number of stator teeth
- number of poles
- schematic of winding scheme (trying to better understand 6-phase)
- number of turns and wire gauge
- pics of inside.
I'll assume the easiest way to power this thing is via two,3-phase controllers, or is there a single 6-phase controller available?
Interesting...John in CR wrote:We want to go the early commitment route to both keep costs to a bare minimum and be able to offer a turnkey plug-n-play solution to those not wanting to do the metal work. That means arranging drive sprockets, axle clamping motor mount brackets, and even ventilation for those wanting to run crazy power.
Hi Boeckstyns,Boeckstyns wrote:Hi John,
Did you receive these motors yet? I have asked you before of the shipping price of the hubmonster but I think I want to challenge my building skills a bit more than a hub build. Does it come with the rim removed as in the pictures? And which shipping rates would apply when you ship from the states(to Denmark)? Thanks.
These are stateside so shipping in the continental US or Canada is simple. We have 15fet controllers with irfb4110 mosfets for $149 for a pair. It takes are pair of them and we pretest and send them out plug and play with the motors. I got some 12fet sine wave controllers in for testing, also with 4110 fets, which I've already tested on the MiniMonster and works well. I'll connect a pair to my MidMonster and see how that works.VoKuS wrote:Hi John,
1. How can I get my hands on one?
2. What are the stock controllers you are talking about in the first post and where do you get them?
3. I am in Rocklin CA, 95677, Can you ship to here?
4. I have access to a lathe, I can turn the outside to clean up the OD if needed, you can ship the motor the way it comes I am planing to turn the shell down anyway.
5. I am excited about this...
That is the maximum speed I want my lead sled scooter to go, on a 10'' rim running on 20S so 74V. But mostly the maximum speed would be under 60 kph as this scooter is a city ride, no riding outside city limits. John are these motors still with the 10'' rim or are all the rims grinded off?John in CR wrote:It's got a Kv of 16 and is designed to run a lead sled scooter 75kph running a 10" scooter wheel.
The batch of motors in this thread all have the rims cut off, so they're for mid-drive use. New with rim are only $35 more, but shipping costs from China will bite harder. I thought your vehicle had to deal with significant loads though...long hills and/or big weight. If so, I don't think MidMonster is the right motor.mistercrash wrote:That is the maximum speed I want my lead sled scooter to go, on a 10'' rim running on 20S so 74V.

PM me for price of one motor with two controllers and shipping to Ontario, Canada please.
