Agreed. The question then becomes why. I feel like the point of a longer bottom bracket spindle would be to allow room for freewheels and support bearings. Adding too much spacer under the cup means whatever extra stuff is on there needs to have a large enough diameter to fit over the cup. I guess t...

You are correct. It is definitely longer overall than a standard 73mm BB. This one that I bought is around 150mm long. I think a standard 73mm BB spindle is something like 118 long. This style of internal bearing bottom bracket does allow you the freedom to run some spacers under the cups such that ...

Thanks. Looks like the thing they all have in common is the same spindle length on the Drive side. I guess I just always figured these were for providing more room for FW BB. They don't seem to provide any benefit over a standard ISIS BB. Time to go list my unused cyclone BB in the for sale section.

What a strange thing. Almost looks like these companies just bought fat bike bottom brackets and turned them down so they are adjustable. If the extra spindle length cant be used on the Drive side then I don't really see the point of buying a long spindle. I need to find a regular ISIS bottom bracke...

I feel really dumb here but I just dont understand the dimensions of this Cyclone bottom bracket I bought from luna. Hopefully someone can explain this too me. This is advertised as the 68-100mm bottom bracket. The bearings on the non drive side are pressed on such that they look right for a 100mm b...

Anyone have a link to some thorough documentation on the 12f, arrived today but I am a newb and need to know how to make up the connections going into the back of the display and I seem to have two extra power wires coming out of my controller unit, no idea what these are for, they aren't covered i...

You need to switch over to high range mode for shunts under .8mOhm Page 28 of the official users manual "Most high current shunts will be less than 0.8 mOhm and the Cycle Analyst must be set to High Range (0.1A) mode to accomodate them. The High Range mode will show power in kilowatts instead o...

Thanks for the link. We actually have the old battery for this that is completely dead and a new replacement battery that the shop doesn't want to bother shipping due to the hazmat restrictions. I'm guessing someone left the original battery alone for too long and the BMS drained it. I can't get the...

Alternately, if anyone knows what the small blue and white wires do that come out of the frame right above the drive unit I'd love to know.

Any takers at $300. Like I said, dont be shy. This is literally a save it from the trash kind of deal. As long as they arent losing money paying a guy to box it up then its better than nothing.

This is a pretty basic Front wheel hub ebike kit. Motor is from Fusin. It appears to be a geared hub but I believe it has no internal clutch so it should do regen despite being a geared motor. Rim is unlabeled but its straight and has surface for typical rim brakes. 26inch wheel. No disk mount flang...

NO LONGER AVAILABLE I'm listing this for a friend who knows nothing about it. It was a donation to his organization. They don't really mess with Ebikes and they would just as soon strip it for parts and scrap the frame. Seems like a shame to waste an ebike. Its an Izip E3 Dash mid-drive bike. The Ba...

Wow. I think you are right on with the Fusin guess. It's pretty small and looks almost identical to a Fusin labeled motor that was sitting right next to it at the shop. What is the quality of the Fusin motors like? It looks pretty nice internally. There are a few other thing making this the weirdest...

I ended up with a hub motor that appears to be a geared hub but has no one way clutch in it. Its engaged in both directions so its capable of regen. I've only dealt with Direct Drive hubs before and didn't know this was a thing. I thought all geared hubs had a one way clutch such that they would fre...

Hard to say for sure. They were designed for hard MTB use. I would think starting from a dead stop in the direct drive position it would be pretty durable. Unless you are pushing harder than a pro MTB rider standing up and stomping on the pedals I would expect it to be well within its design paramet...

It is currently in a 73mm BB frame. It originally came with 2 bottom brackets. One for 68/73 and one for 83mm BB. The guy I got it from is supposed to be mailing me the other bottom bracket so I should know more soon. Yeah I live and ride in STL. We should meet up sometime. There arent many of us in...

How are they laid out? Are they just bricks of 20 pouches in a row? Have you found any bad cells in the batches you purchased? I'm assuming these are the lightly used ones purchased from one of the common salvage websites. Where are you located?

That looks like a pretty nice kit. Also love that Amazon feels the need to warn us that it contains small choking hazards so its not suitable for children under 3 years old. :lol: Anyway, I don't know about you guys but I have come to the conclusion that most of my soldering problems are solved by f...

I can tell you how it used to work. There were several programs like keywin, and xpd, as well as one from Lyen that he emailed with the sale of a controller. You plug the cable into usb, download a driver for the usb to serial conversion and then you could use any of these programs to set up your co...

Yeah. 160 is pretty short but since we are all weird ebikers I figured they might actually be a hit here. Lots of small diameter hub motors around here than in the pure mountainbike world so the extra ground clearance is nice. I'm 6' as well but when I'm spinning like crazy trying to pedal along at ...

I got this as part of a used frame purchase. Its a little bit rough but these were pretty durable and expensive when they came out. Figured it would be great for pedaling along with a hub motor or as part of a 2speed transmission for a mid-drive. The current chainring is 24 teeth but with the overdr...

Yeah. The shipping thing is always crazy. Given our current trade relationship with China and the Pandemic I think its the worst possible scenario right now. Hopefully that price goes back to what It was. If that gear reduction is halfway decent in terms of reliability then I think its absolutely pe...

This guy is building a light trail/trials bike and bought the qs 3k motor with the integral gear reduction. I think he said it was around $300. So i think it is available.

Ferrofluid and hubsinks work very well. People on here have made liquid cooling setups with tubes that run through the bearing but its major work. If you have a machine shop and some design skills there is no reason you cant liquid cool a motor. Its just generally not cost effective. Finding the roo...

Good. Have you messed with programming one of these lately? I tried the other day and none of the programming softwares would work on several computers. I tried Lyen software, keywin, and xpd and none of them worked on any of my "infineon" based controllers.
