Re: new cyclone 3000 w mid-drive kit?

I am planning on using the cyclone 3000w on a quad I am designing where the motors would be directly connected to each rear wheels via a shaft. The wheel has an OD of 23" which means if the motor spins 900 rpm (what I've read) that would mean a top speed of 59mph! That is way too fast. Can anyone ve...

What if... smartphone ebike computer

All I've ever seen for ebike computers are these 90s looking lcd display type computers. Does anyone make a full touch screen, full color computer? Maybe it could run on an old cellphone? Or better yet, it could run on your own cellphone and charge it! Whats out there?

Re: Full Suspension Rock Bouncer Inspired Quad Build

Thanks for the input guys. Its always great to see first impressions. I should probably clarify, my intent isn't to go rock bouncing in this thing. Its more just the 4 link suspension front and rear that has me calling it rock bouncer inspired. I'm just really liking how simple it will be to build f...

Full Suspension Rock Bouncer Inspired Quad Build

This is going to be my build thread for my electric quad cruiser I'm building. I've been throwing lots of designs around with different suspension and motor ideas. I've pretty much settled on the design I have now which should have good suspension travel and articulation while being relatively simpl...

Prototyping/Simulating Omni Wheel Vehicle Control

Fair warning this is probably not the place to ask this but I have not idea where to ask so I'm looking for clues. I designed some wheels that spin 360 degrees that are based on NASAs mrv wheels.

Re: High Torque Hub Motors

If you want to use a "normal" controller with smallish phase wires and a modest battery, the 6T MXUS motor is the best winding for you application. John is absolutely correct that every winding of the MXUS can produce the same total torque, but he refuses to admit that it's more practical to use a ...

Re: High Torque Hub Motors

Basically my benchmark for hill climbing ability is this hill near my house in Pacifica, CA. It's a steep dirt road about 1 mile long with an elevation gain of 1000'. If I could get up that in one go without stopping that would be great. (see pic of hill). As for top speed - I don't see needing to g...

Max speed @ 49 volts is 18mph on a recumbent trike.
I think the mxus 6t would be a good fit and it would not over heat.
I think that (mxus 3000w 6t) sounds like the ticket. I'll give it more volts too. Also it will have two so should be pretty fast!

Re: High Torque Hub Motors

The slower you run a motor, the less efficient it becomes when producing torque. If you try to run a normal direct drive hub motor at 6mph while crawling over things, it's going to over heat fast, and suck your battery empty at blinding speeds. If you want low speed torque, you need some form of ge...

High Torque Hub Motors

Hey Yall, I am trying to find high torque, low speed hub motors for my quad bike project. Looking at videos of the mxus 3000, It looks like they spin way faster than I need. i want this buggy to be comfortable climbing hills slowly. Are there any geared hub motors?

Re: Full Suspension Quad Bike Build

Just an update on current things I am researching... I was almost persuaded to use hub motors for this build but after seeing that the mxus 3000 weighs in at 20lbs.. I just dont see one sided mounting working well. So I am back to the inboard motor design for now. (It's much sexier anyway) So my cur...

Re: Full Suspension Quad Bike Build

Not ready to give up on the in-board drive just yet. Does anyone know of a motor that would be good for this? To go 30mph using the config shown the motor would be spinning 3000 rpm. Don't need any faster than that. Just estimating I think 2000w sounds about rtight. (There will be an identical setup...

Re: Full Suspension Quad Bike Build

Maybe an alternative idea for the rear is to use two independent suspended moped or MTB rear swingarms/forks with a hub motor in each (2wd). I'm not sure what speeds the Magic Pie in the cast 20" wheel (with sticky 16" moped tire) is capable of. But that way you would have serious acceleration and ...
