@Chambers Frame is looking really good and sturdy...excellent work :bigthumb: Motor is mounted just through the bolt pattern?

I will step in for discussion purposes. Thanks Joe and good pionts, you are right about the bearings are a good solution in this application (if proper machined after welding and really good looked after). But lifespan is short and must be changed frequently, on failure they really often jam up...

So you are flexing the hole rearend(swingarm). With all these edges inside, cracking will start there. My experience out of 22year riding the sh.... out of two wheelers---dont get to fancy with suspension itself. As long as rearwheel travel goes kinda linear with shocktravel it will ride...

Haha, i know this loose concept things pretty damn good! (piles of them in my workshop) :lol: Unfortunately iam sticking with Fusion360 atm. otherwise it would be easy to mod some things. maybe the fastest way is a good sideview from your designs and with the good old fashion way in"paint" i...

Sorry missed the new posts...that looks really sweet! is the pivotpiont in the chainline? If its higher or lower will lift up or pull down the rearwheel...something to consider at 3kw, maybe ;-) sharp edge from the horizontal bar to the short round bar(swingarmpivot) will be a weak piont too...

Have a look here https://endless-sphere.com/forums/viewtopic.php?f=31&t=106778 the stepdown bend prevents from thermal expansion in all directions. as far as my knowledge goes, was/is that a big reason cells are failing in a pack.

Here are all information in the forum to be Electric-drivetrain-magician! Measurements is what you need(others to help). First measure resistance of each motor phasewires to the others...same on unpluged controller, but phasewires to negative and positive(just to double check). Also check...

in your second pic 2 phasewires are touching the stator, so i would start there.

Hey Chambers, great looking bike and mint design skills! looking forward to see the prototype running. Maybe consider mounting the shock to toptube(less stress for the mainframe) and the rearend pivot piont in the seattube(mentioned before) with the full width of your frame(thats the weak point...

I am reading with huge interests yours and shamans posts. These controllers are what i am(and a bunch of other users) are looking for. So please make a paypal link and i am more than happy to back you up! Hope i can get my hands on one of the first batch. Thanks for sharing and making it...

Nice Controller project, looks like what everybody should own :thumb: i would like to get my hands one some these, for testing and happy to leaf some cash for your effords!

Looks great, never heard before and happy to give it a go! Have the same problems with FB, but cant leave after 4 broken phones and 2PC sh:t them self. only contacts where there and to keep in touch with my international friends there. did you guys hear of "Humanconnection" ? but they are...

Hey John, maybe mosquito is something for you. the tilting mechanisms looks really slick : I had quite some 3 wheller, but for my self there are more disadvantages in space and stability then with 4. And the jk velo2 is also going for 4 wheels and suspension. But your 2 wheel idea with some...

sweet build!!! we should get in touch for some brainstorming, preparing a similar project, have a workshop and from Germany as well :mrgreen: pm ed you

Hi Guys, i am also keen in building a high tech full suspension 4wd ...let´s say pedalcars (velomobiles). one of the most exciting designs i think is this: and for making an relatively easy body, foam with polygon design might be the material of choice like: www.jk-velo.de.rs for...
