Re: 2016 Electric Motion EM 5.7 Upgrade

I'm not a trail rider but it reads like it would be beneficial to have a "flywheel motor" with a clutch on a trail bike. Basically a QS205/50H hub motor with a thicker outer ring (not lathed down in the middle like normally to create the spoke flanges) and a clutch between the (stronger/reinforced) ...

Re: 2016 Electric Motion EM 5.7 Upgrade

I suspect a Thermo Nucular 24F would do great. In many cases the Nucular makes a motor run cooler at the same amp input. I would suggest to up the voltage of the battery and system to 20S at least and increasing the Ah capacity for a "stronger" (less sag) pack. That automatically gives you a higher ...

Re: 2016 Electric Motion EM 5.7 Upgrade

I don't know if you use the top speed a lot? If not maybe shorter gearing might help?
The Nucular controller might be a good upgrade indeed.

Re: LG 16S 60V 1.5kwh water cooled modules for sale (EU)

They seem to be from November 2014 so 5 years old. Do you have a possibility to test the remaining capacity? That would give a clue to their health.

Next time perhaps you will remember to use a U-lock. Even the shabbiest of those would not have given it up so easily.

Re: My first generation of central motor CNC scooter

It seems like your front suspension design has no trail or even a little lead on the front tire contact patch. But the angle of the photo is not good enough to see it clearly. Is your scooter not too nervous when riding higher speeds?

Hi guys, report from the belt testing,
Great result!
And very well executed. The wrapping so far round to almost 9 O' clock is a bonus to not getting stuff caught between belt and pulley.
But it looks like the bolt of your rear shock is missing or is that just my imagination?:

Re: Conversion Honda motorcycle to electric 96v - 8000w hubmotor - 6.3kWh

:thumb: Yes that seems a very smart way to replace the lost strength that the removed engine provided. If you build the battery box/frame out of metal tubes or plate and integrate (welded or bolted) that as well into the total frame structure it will probably stiffen it up even further.

Re: rieju smx conversion project

Good idea and worth trying! :thumb:
It seems to counter the unsprung weight of the rear wheel so the shock will "feel" less weight compressing but more in rebound. So you might have to change or revalve and respring the rear. Is the room left in the frame enough to house the battery pack?

Please be more clear. I was only trying to help and advise this OP to use the motor on the crank and not directly to the wheel as aiding the pedaling through the gears seems more efficient.

Re: 250W RC belt drive - how to pick voltage/gearing for best efficiency

They use a potentially 2kW motor with a 1:10 gearing on the crank. That means that it can only deliver roughly 200W continuous an around 400W peak power. It means nothing of the sort. Watts is torque times RPM. Reduction decreases RPM while increasing torque. Provided you have enough volts and ampe...
