Endless Sphere

Hope you'll have it fixed soon. It's a really nice project to follow. Photo's of the process are appreciated here
Good luck

Conclusion: Diameter (287.4mm) is a few mm less than the 295mm of QS273, could be problematic for a good contact surface with hubsinks. :idea: Get a 15mm wide, 902mm long and 1mm (or 1.2mm/1.5mm) thick aluminum strip cut at a customer friendly fabrication shop or sheet metal supplier. Every 1mm thi...

Btw.: I asked for the weight of nissan leaf motor controller unit which is available here also in Germany: https://www.ebay.de/itm/MOTOR-EM57-EM61-Electric-Nissan-Leaf-ZE0-80kw-109ps-2016-Bj/192909421759?fits=Model%3ALeaf%7CMake%3ANissan&hash=item2cea4c2cbf:g:TCoAAOSwkoldh4i8 You wanna know which a...

Where does the tire mount on that motor?

You really seem to suck at googling and reading...
I wish you well

The words "due to budget" don't go well with "what is the most powerful motor you make"... I think you need to read up on all the pro's and con's of all the type of motors (hub, mid drive and the different types) available out there. And then see what is the best choice for the type of vehicle you w...

Thank you.

I have sanded the shunt by %30 now it is perfect!

Cheap fix
And the opposite of what most folks are trying to achieve (more amps/power)

Great work and nice build!

What is the most powerful motor you make? That depends on what application you need it for. Is it for a bicycle, moped, motorcycle, car or something else? If I remember correct they are also able to make a double stator hub motor. In the basis it is as the title says: 0.5-14kW. That is continuous s...

Then see what motor/controller brand and type you have in your Haibike and google the possibilities.

In our country (NL/EU) the Tesla Model 3 was the best selling (new/lease/company) car in the month September. I suspect it will keep the lead until the end of the year. But next year the tax (bijtelling) will go up for company electric lease cars so that might change things.

That's why most people here build their own bikes. And use motors and controllers they can modify themselves. I don't know what motor/controller combo your bike has so no idea what is possible. Maybe you could have googled it yourself...? https://www.ebiketuning.com/ Or just sell the Haibike and buy...

So 401Nm/7.94 (gearbox reduction)= 50.5Nm from the motor. I think the 400Nm must have been from the motor. Yes of course it is 400Nm from the motor, the factory Gen1 leaf makes 280Nm. A puny e-bike hub motor makes more than 50Nm. That would mean that multiplied with the 7.94 gear reduction of the L...

That will be better indeed

So 401Nm/7.94 (gearbox reduction)= 50.5Nm from the motor. I think the 400Nm must have been from the motor. No it was 296 lb-ft at the wheels (see from 56 sec. in video on the dyno) and the Nissan Leaf drive train has a 7.94:1 reduction inside. That equals 401Nm at the wheels. I don't know the inter...

I do apreciate your advice, but my back its broken, i do have one hernial disc on my low back that its driving me crazy. So im not going to make trails or rought terrain as i use to did. Mostly using it to go to work and have a ride around the mountain. Im not into downhilling anymore. I do have an...

If you use the calculator I linked to then 600Nm at 4000rpm gives 337hp. So roughly the same as the Nissan Leaf motor with Arlo's controller/inverter. That would cost less than €2000,- for motor and controller/inverter. How much will you be spending on the motor and controller you have (ordered)...?

600Nm without a reduction gear...? :shock: Then it will be even bigger, heavier and more expensive than this: https://www.evwest.com/catalog/product_info.php?cPath=8&products_id=297&osCsid=8kfke42jer6bombr9fe899d8e1 Because that "only" puts out 380Nm and is already 68kg by 26cm diameter and 31cm lon...

What is the asking price?
And where can I find info/link about the manufacturer/builder?

Wow nice build! What battery cells are those? And did you keep them that far apart for cooling? Otherwise it seems you would have room for more cells when getting them closer together. And with more cells in parallel they stay cooler anyway. Also the seat seems to be very far rearward. Keep up the g...

Arlo got just above 400Nm and 300bhp from the standard Nissan leaf drive train: S6OInkLWAhk So 401Nm/7.94 (gearbox reduction)= 50.5Nm from the motor. You would need a higher top speed so can probably change the final reduction to 6:1 (or even 5:1) with the sprockets. Here is his thread: https://endl...

Why not hang the battery pack under the lower frame tube for a much better center of gravity? Then it will handle a lot better. Even with that geometrically changing springer fork...

I think that the Super Soco would be especially good if it is for a club where different people will make use of it. It probably would need little maintenance an will be easy ridable for most people. Just make sure that if it is used outdoor that it complies to your local law and insurance laws. In ...

It irks me that I can't fit the BBSHD inside the triangle. So my next big investment is to make my own engine casing and system. At the moment I'm looking at the Astro 3220 and the Revolt RV-120. Suggestions welcome. Youtube video soon. Very nice bike! I think you could better get a CYC X1-Pro (3kW...

Why not buy an existing electric scooter or bike that can do that? A Super Soco or Sur-ron (with road tires) or something similar could be suitable? https://supersoco.com.au/ https://voltbike.com.au/product/sur-ron-light-bee/ If you want to keep it small and light you can consider a road race bicycl...

:thumb: Instead of just buying a Nissan Leaf motor from the scrap yard and a controller to drive it (200+kW peak) you now have to wait up to 14 weeks for an experimental motor. That has never been run with your controller and have to hope you can get it to work. You are a brave man although a little...
