Hub motor as mid (illegalbike) 6000-12000W / 33-35kg

CNC art!

Just curious, how long do you expect the gear to last? Not that it would be a problem seeing as how easy it is for you to cut another.

I expect a long life, since this is D16t alloy (a more famous analogue in the west is alloy 2024)
There are many factory sprocket made of this alloy.

Nice work! If you added pedals, it would be easier to mistake as legal.

Thanks!
The pedals are awkward and unsafe on a bike like this.
Legally in my country it is not important to have pedals, motor power less than 4000 W is important. I have a 1500 W motor

I feel so cheated. This is one of my favorite builds but now you tell me it's actually "legalbike".

I am a law-abiding citizen. But on this bike I often hear a police siren from behind )

loooool. Now I now what to tell the next guy claiming that everything sucks in Russia. 4kw is quite some power for an ebike.

One thing I'm wondering about this build though: doesn't that 7kg spinning hub in the mids of the frame create a weird gyroscopic effect on the overall bike when change directions ?

At the moment, no documents are needed below 250 watts. From 250 to 4000 watts, the driver needs a helmet and a driver's license of the "moped" category, which can be very easily obtained from the age of 16. If the driver already has any other category (motorcycle, car, or truck) then you can drive vehicles up to 4000 watts without the category «moped»

Only the shell with magnets spin, it is about 1-1. 5 kg. Since the rotation is in the middle of the frame, it can have a positive effect on the control, but 1kg at 1000 rpm is not felt for 33 kg bike + 80 kg rider

total weight of the bike 33.6 kg (74 lbs)

That's actually pretty good. My commuter with a simple bbs02 weights nearly 29kg...

Most police don't carry around a wattmeter and wouldn't have a clue how to use one anyway.

Way back, someone made stickers for their motor:

4kW on a lightweight bike like that will be a lot of fun.

frame will be painted soon

Sweet bike !

The standard sprocket thread would unscrew in this configuration. I was wondering how you attached the sprocket to the motor ?

It looks like the Polish version of Endless Sphere:

Cool looking bike.

The paint job came out looking nice. Now the battery...

another bike for a friend

He's very lucky to have you as a friend!
If you want to have a new friend that would love to have a bike like that, pick me please...
