There still needs to be a slotted frame mount for them to go in, for chain tension. I would think. :?: Sure, you can still ahve a slotted frame mount, but just like a bike axle / dropout it doesn't have to resist torque. :) I really don't like the flats either, but I thought for a thousand watts of...

You might want to look at my SB Cruiser trike thread for ideas. It was really built to carry Tiny, a 100lb St Bernard, and assorted cargo (groceries, etc). It's been thru a lot of variations, but it's present one has hauled a piano in a trailer, and easily hauls one dog in the trike itself and anoth...

You could put a thermal switch on the fan so whenever air gets above whatever temperature you want, it switches on automatically. You could put a second thermal switch at a much higher temperature that shuts down the A/C units to prevent damage. My guess is 130-150F range is probably beyond their op...

One thing I'm a little unsure of now is whether or not a person can run a hub motor backwards at full speed <snip> in conjunction with the hall sensors, Works fine with any motor that has neutral timing on the sensors. All the DD hubmotors I've had appear to be. I"m not sure about geared hubs, but ...

First connect throttle directly to controller, bypassing the CA, so the CA can't be limiting the system. If the problem continues, it's not the CA causing it. If the problem stops, then something in the CA is limiting, potentially causing the issue; you'd need to review the limit flags screen to see...

FWIW, not all sensorless controllers require externally-started motion to work. Lebowksi here on ES has solved that problem for the new version of his controller. There's probably others, too, in the higher-end stuff. Regarding geared hubs and sensorless controllers, my experience so farwith one sys...

FWIW, the MXUS 5k discussion thread says it's threads are M35x1.

Just based on personal experiences with flatted-axle failures, I highly recommend a completely different axle design. ;) Axle flats are a terrible way to transfer torque, and are mainly used because someone once did it because it was easy and quick and "cheap", and everyone else copied that. It does...

On the dropout part, it kinda depends on what kind of torque levels you're after, and what the specific motor you're going to use is going to have in combination with the controller and battery pack you're running it with. As well as how that specific motor is designed to do it's torque transfer. Th...

For the one in my SB Cruiser frame, I just took a cog off a generic multispeed freewheel, https://endless-sphere.com/forums/download/file.php?id=202692 removed the tabs from it's inner circumference, and welded it to the flange. https://endless-sphere.com/forums/download/file.php?id=203309 I'd tried...

She's pretty similar! Same color , although the headlight is on the handlebars, not mounted to the front like that :). Specifically, she's one of these: Unfortunately, like the first post's image, it just comes up as a minus sign in a circle. If you attach the image directly to the post, it'll show...

Yes...ask Dogman Dan about it's effects. I think it's been ten years and he's beginning recovery. :/

I don't have any machining advice, but it'll be cool to see that going. Does it look like the one Reki rides in Haibane Renmei? Or is it a different one? op-07.jpg At one time I had a rusty old '80s Honda (elite?) I wanted to convert, but I went the electric bicycle route instead. (I did use some of...

If the problem with cheaper BMS is that they won't handle the output current needed, you could use the gate drive for the insufficient output FET stage to instead drive a bit of electronics (transistor relay driver, etc) that turns a contactor on and off.

Much cheaper than the Orion system.

Ok, got to the PO so it's on it's way back now. In the meantime, I'm considering a serious change to how my hubmotors mount to the trike, partly just so I never have to deal with axles broken by torque again. Not sure I can pull it off, but here's a thread with the idea: https://endless-sphere.com/f...

This isn't a typical single-ended axle kind of thing, nor can it be used with any hubmotor until the motor is highly modified (but which modification is actually pretty simple). It requires a DD hubmotor to do it; I don't know a way to do it with a geared hub yet. But...if you have a motor laying ar...

It's been done a number of times over the years, with plugs and with switches and relays and with active electronics (like the "antitheft" option in some controllers), etc. A plug is safer for you than the switches or relays, because the latter two have the possibility of a contact switching failure...

If the unit is not sealed, you can open it up and replace the center switch with a push-on push-off type. I'm not familiar with that specific unit, so I'll ask a question that might be dumb but: Is that switch wired into the other stuff in the unit in any way, or do all the wires for that center swi...

No one charger is best for everything. But the closest you can really get for "charge anything" that's high quality from a company that supports it (still makes firmware updates too), is probably teh Grin Tech Cycle Satiator http://ebikes.ca/satiator There's more than one version depending on the pa...

Not sure if it's helpful, but others have used similar ones:

If you still need the pack to shutdown on LVC or HVC, then you can "AND" the two gate signals from the BMSes, and have them drive a single relay (contactor) on the pack positive (or negative, whichever works for your system), via whatever small electronics is necessary (transistor driver, probably)....

I like to get torque up to to breaking axles, then upgrade the axles until the frame breaks, then upgrade the frame till the axles break, and so on.

I am not saying the kit is falling apart at every turn but at the same time its not rock solid. Maybe I need to manage my expectations? And it doesn't help that the seller only wants to sell me stuff and not warranty items and relies on the ambiguity of a customer installed kit to cast doubt about ...

Shorted MCU. I'll send you the return address by PM. I got the PM; I'll get it sent out as soon as possible; I work hours that won't allow me to make it to the post office in time until Thursday, unless things change. Before I send it off, if it is ok with you, I'd like to open the case and take a ...

Single red- electric door lock cable? No clue what that does but you don't need it. One of the other red wires is likely the 'ignition' line that needs to be connected to pack positive to power up the controller. Actually it probably *is* the "ignition" or "keyswitch" wire; some of the translations...
