I am going to mount a 10T sprocket from Panasonic E-Bike to a Hoverboard motor in the next days: www.bike-discount.de/de/kaufen/wippermann-connex-e-bike-ritzel-fuer-panasonic-motoren-antrieb-z10-459952 Stay tuned :-)

Thanks for sharing. On a side note, you sound exactly like Arnold Schwarzenegger at certain moments and I find that charming.

thanks. My chest is not big enough to voice a baritone like Schwarzenegger but i am getting more and more lazy on pronouncing the english language nicely. Therefore my German accent becomes more obvious. And in Austria where Arnold came from they speak German too.

Great idea ! Could you tell me how watts that motor have?

@robodurden 2 жыл бұрын

250-350+ Watt per motor at 36V = 10s Li-ion. 12s is possible.

Hi Robo, can I hire you? My project is: hoverboard motherboard with a pot for forward driving, a pot with backwards driving and a pot for steering. Can you configure something for me?

i don't work for money, only for happiness. And your proposal is way way not happy enough.

Am i wrong ,but i think the freewheel should be in opposite direction? I am also working on this problem.The freewheel that can be turned around is at least16 teeth.The small ones cant be turned around.Or yor mount at the bike is on the left side to work?

@robodurden Жыл бұрын

A freewheel should spin freely counterclockwise = back pedaling. The hoverboard motor should be placed after the pedal crank where the chain is going back to the back wheel. Like the old Panasonic middle motors. That way you can pedal without the motor turning because the freewheel skips. But when the motor start counterclockwise, the chain is pulled. So freewheel sprocket pointing to the right side of the bike.

Does anybody know how I can open the hoverboard motor? After I remove the 6 screws it is still stuck. It seems there is something else to release

@robodurden 3 ай бұрын

Two flat 🪛 screwdrivers from opposite sides to push the backside a few millimeters apart.

I don't see this holding up too long after watching the whole thing. No disrespect to the maker of the video. It's just not enough strength to transfer the torque effectively. The screws will twist off when weight is applied to the bike it is set-up on. The crank needs to be fashioned to the motor itself to get proper power from the motors transfer of power.

I just don't see how else to do it. I too have considered the project with my own hoverboard wheels. Just hadn't had the gumtion to actually do the work yet. But thanks for sharing the video. Sorry to burst any bubble on the project just hope it helps with where you are going.
