Re: Searching for my personal battery apprentice

I sent you a PM before I made that post. Is it not in your inbox? When I go to work, I go to work sober, although I do like to use drugs in moderation at home when I have the spare money for them. I've been studying EV technology for decades, and sadly have never had the chance to put any of what I ...

Re: Searching for my personal battery apprentice

That's because you've just never wanted to sloooooooow down. Which is what Methods said the vodka and pancakes were for. I don't understand the context of this statement. Do you have a link to the relevant post? I like alcohol on occasion(once or twice a month, and only when there's enough money to...

Re: Searching for my personal battery apprentice

PM sent, even though I'm not a good match. This would be a dream job for me, in spite of my current personal situation that would prevent me from fulfilling its obligations. Maybe some day the circumstances will align. While living on vodka and pancakes. No way I could do that. I eat mostly fresh pr...

Re: Leaf / leafmotor / leafbike high efficiency 1500w motor

I think the cassette side already has an M12 compatible pattern. I'm using an M12 nut on the cassette side, but I'm going to upgrade it to an automotive grade M12-1.50 wheel nut. I received the following email from Leafbike: if your motor from our company. We have washer and nuts to replace. (Put 2 ...

Re: Leaf / leafmotor / leafbike high efficiency 1500w motor

I think the replacement nut stripped my threading on the cassette side of the axle. The odd thing is that it did not show any indication of cross threading when I installed it with a small crescent wrench and took very little force to turn. I was mostly able to turn it by hand. The nut was still tig...

Re: Leaf / leafmotor / leafbike high efficiency 1500w motor

The cassette version of this motor has a smaller axle on one side, correct? Correct. if so, it's even more critical to use tight fitting torque arms! I would make your torque arm even stronger than this. You can see i had a long aluminum bar in one pic. A shorter distance would have been preferable...

Re: My first ebike build: custom-built KMX-based electric velomobile

I'm going to try that.

I plan to do long-distance touring with this thing, regardless of whether I soon end up homeless or not, so keeping this thing reliable is of utmost importance. It is neither easy to carry nor inexpensive to tow or ship.

Re: Leaf / leafmotor / leafbike high efficiency 1500w motor

If the axle nut came off during regen, then it was already very loose, ready to fall off. Likely. This usually means, assuming it was tightened enough to start with, that the axle is rocking back and forth in the dropouts, even just a tiny bit, which eventually works the nut loose, and then vibrati...

hitting bumps like train track crossings at 46mph, how does the front suspension handle it? I haven't hit a railroad crossing at that speed. The rear wheel is unsuspended and there is a possibility that scenario could cause a loss of control. I plan to add a rear suspension when finances permit, wh...

Re: Leaf / leafmotor / leafbike high efficiency 1500w motor

I lost an axle nut today. I have the cassette version and while executing regen, an axle nut on the drive side came loose along with the oblong shaped washer. I couldn't find them on the road and they may have rolled off into a ditch or gutter. Does anyone know where I can source replacements? I wen...

Are you sure you want to go 46mph in that? NO protection there. Of course I do! What I don't want to do is WRECK at 46 mph, or really any speed for that matter. If one were to jump off of a 6 story building, they'd smack the pavement at close to 46 mph. I see people with tadpoles who have a flag ab...

I've put 199 miles on the vehicle as an EV thus far and have placed 6 cycles on the pack. I even discharged the battery all the way down and got 8.95AH...

Re: Critique this performance velomobile idea

A little birdy whispered into my ear recently and told me that an ebike company we know and love has experimented with a DD hub with 0.27mm laminations. No timeframe was provided :/ Probably not Leafbike, since they already make DD motors with 0.27mm lams. Hopefully it's something that exceeds the ...

Re: Critique this performance velomobile idea

After all, current hub motors fit their niche quite well. They are low cost suitable for conversions, and perfectly adequate within the intended performance envelope up to 28mph. Into 30-40+mph, full suspension becomes more desirable, where unsprung hub motor is undesirable -- which isn't to say th...

This system would be inter-changable with having pedals or not having pedals and will do well either w...

Re: Critique this performance velomobile idea

But R&D doesn't occur in a vacuum -- it's driven by market forces, and there's no market for high-end hub motors, or else we'd be using them. The R&D by Brose, Bosch, Shimano, Yamaha goes into mid-drive, which makes sense if you're developing a platform and not just a conversion. "Mark...

Re: Leaf / leafmotor / leafbike high efficiency 1500w motor

If you get the standard 4T leaf and run it in a 26" rim you should get over 70kph at 16S. That is more than enough speed IMO. I'm getting 75 kph out of a 13S3P pack of Sanyo/Panasonic NCR18650GA cells. But mine has greatly reduced aero drag plus the aid of strong legs and a wide gearing range....

I finally topped it out. The Cycle Analyst says I reached 46.0 mph. Not bad for a 46.8V nominal pack limited to 1,250W!

I intend to modify mine in a similar manner at some point in the future.

What voltage can these be run at before any arcing over occurs? I...
