Re: MXUS 3000 Hub Motor

Tesla..great info .. Maybe you should try and outline the benefits of each type motor you are selling , on your website... for example... for your average rider, I would think they would be interested in no more then a top speed of 30-35 mph with the best torque/ efficency possible, using a 48 volt ...

Re: Wave Ebike another Indiegogo backed Alibaba quality bike

Do you guys think 3 front gears would make a difference in desirability? Or would the preference only be to have rear gears? I think your formulae is a low-cost eBike entry. So the typical 3 gears on chain-ring. Adding in a cheap deraileur might spell trouble, because they'd tend to need service. A...

Re: Latest air cooling mods for ebike hub motor- with drawni

As the wheel rotates, cool air is forced into the open end of the plastic air scoop..and since the back end of the air scoop is closed off, the cooler air is then forced into the inlet cooling hole , over the coils, then the hotter air leaves the hub thru the exit holes....as long as your wheel is r...

Latest air cooling mods for ebike hub motor- with drawnings

First I need to apologize for not posting photos of my heatsink cooling mods.

Re: JP spot welder

Yeah, between 380 and 1100 A rating is ok, depends on what thickness of material you want to weld. I'm really not sure for 8V though, maybe the same rating, but longer pulse. I would imagine that not only a/h capacity is important, but cold cranking amps ? In other words, using a ATV or Lawnmower -...

Re: E-bike full size waterproof canopy needed

This seems to be something that is missing in the bike/ ebike marketplace...but has huge potential for profits.

A easily accessible canopy , for a fair price , that would be fairly aerodynamic and not risk killing the biker in crosswinds .

Re: JP spot welder

Yes you need to wire up the power supply and observe polarity. Use a multimeter. Perhaps Riba will have to start supplying the wall wart. :-D 200mA is probably fine (not mAh) well, no need for him to supply the wall wart 12 volt dc power supply...but you must understand, he lives in a different cou...

Re: Difference between the MXUS 3000W - V2 - 4Tx16 and 5Tx12

No one can compete with a $200 Yescom kit. At least not presently. I would be that this is why em3ev.com, ebikekit.com and various other ebike retailers stopped selling the 28mm DD Hub. They may have a better 28mm motor & Controller combination, but all a consumer sees is the bottom line price. - I...

Sorry, I actually meant to post this in another MXUS thread. The motors I am referring to above are 28mm Stator Motors. Pricing will be a little higher than the Yescom kits, but the performance should be SIGNIFICANTLY better with a 40A Sine Wave Controller and a 90% efficient motor design. And the ...

MXUS requires a 20-Motor Minimum order. I am planning on bringing in some of these in 9X7T and 10X5T windings, along with their new Sino Controllers. I think these motors and controllers could be the Yescom killer. :twisted: It may be hard to beat the value of the $193 yescomusa - 1000 watt kits wi...

Re: I have found a way to easily and succesfully cool hub mo

If both heatsinks are being bonded to something with uniform heating, and the thermal resistance of the bond is the same between the two, the thinner backed heatsink would be the highest performance, as it has less Rth induced delta-T through the aluminum itself. Get both and try both if you care e...

Justin, the more I think about this, the less sense it makes to me.

This seems illogical to me, since we are talking a...
