So that is a great "mistake"...
Now get a good 48V 50A (or higher/programmable) controller and get a 48/52V battery that has the continuous current rating to power this motor. In what type/brand frame and wheel diameter is it going?

So hurry up and finish it!
And then shoot some video to make us all jealous

Why is it the wrong hub motor? What did you expect to receive?

Great upgrades!
It will take huge skill (and balls) to ride that thing at it's full potential...
Would love to see the ride video's

What a special way to unlock the speed potential:

I like it a lot and it is priced very competative starting at €2799,- in our country (NL).

What's the bike on the right?

You mean madin88's own project bike?:

Why not put in a new fan?

Then look at the work Paul has done to control the Nissan Leaf motor. He sells boards to drive AC and DC motors. You would have to buy the 3 IGBT half bridges needed to get the power to the motor also. But that should be a lot less expensive in total than the $8k for an inverter you quoted. Here is ...

Great progress! I do hope you will drill the hole to mount the rear shock on the swing arm at least 10 mm higher than the black dot. Otherwise it seems the shock will be solidly mounted to the swing arm without the possibility to rotate around the bolt hole. And to get a better angle for the shock m...

Paul and Arlo here on E-S have experience controlling the Nissan Leaf drive train:

If you want a step up from a QS205 and are able to stretch or build the swing arm to 200mm drop out width then go for the 273 V3 50H spoke hub motor:

Beautiful engineering from Bosch and a nice tear down from you.

And please show your own design here also.

If you can get a torque arm between the axle and the drop out ("inside") you might be okay. As you are going to go from that cassette to a single speed it might be possible.

That's 14kW max...
Great motor indeed!

We were specifically asked not to talk about the X bike on the forum by the factory. That seems a bit strange. Maybe it's not really ready for prime time yet. Maybe because then nobody wants to buy the current model anymore and they can't get rid of the "old" stock as everyone wants an X version?

With 48V and max. 150A cont. printed on the motor it seems it's a 7.2kW motor instead of 14kW (peak?).
Good luck with the sale though. Seems a nice package for a project.

I think you're looking for this controller package:

Hello Kajman,

How many cells do you have left?
What is their size (LxWxH) in mm incl. the terminals?

You could perform a shunt modification. That way you don't need to by any new components or program anything and just get more amps (= more torque) from your existing controller (and the rest of the stock components). Here is some information: https://endless-sphere.com/forums/viewtopic.php?t=29097 ...

WOW!
What a beautiful frame
Keep going and updating this thread.

If that is your use then you're fine and don't need to upgrade the motor. If you find the motor gets so hot you can't touch the cover for more than a few seconds just perform a reversed shunt mod. on your controller. By scraping of some metal of the shunt the max. amps that the controller will put o...

Directly would mean 110V from the generator to the 12V input of the motor. It would go up in smoke...
Use a 110V to 12V converter that can deliver 50 amps and Bob's your uncle (or aunt, who knows these days...)

You should be fine as is. Only if you have the motor in a large wheel and have to climb very long hills the motor might overheat. Put in some ferrofluid / statorade to keep it cooler and/or check the motor temp in the beginning after your heaviest ride (low speed high amp climbs). What is the size o...

Good advice from Chalo. If I found the right photo you have a 24" rear wheel? So you would need the Q128C (=cassette) in 48V and 328rpm to reach the speed you want: https://bmsbattery.com/ebike-kit/769-q128c-135mm-500w-rear-driving-ebike-hub-motor-wheel-ebike-kit.html : ask for the 24" wheel.
