Endless Sphere

Tread revival! A lot of real life things came up which benched the project for a while but I'm back, and with new toys :) Ender 3 S1 Pro.jpg I have been supplied CAD files for the new QS138 90H with gear reducer (under NDA so I cant share). More updates soon but I will likely make a proper build tre...

I have requested a .STP file for the 90h V3, I'll share it here once it comes through.

I am doing a similarly spec'd project with a DRZ-400SM. What made decide to go with the SL controller and how much does it cost?

What CAD software are you using for these drawings and how did you get such a high fidelity model of the donor bike? Nice work. The photos are from Rhino5 and the model is a mesh made from a 3D scan (not mine) of a DRZ 400 E, I just added the motard specific items and tweaked a couple of things. Wh...

There are many examples of people using these controllers in bicycles and smaller framed motorcycles (Surron esk). How do they fair in full sized motorcycles? I'm doing a conversion of a DRZ 400 SM and the 24f + computer + ulight is a very attractive package, especially because I want the bike to be...

Here we go. For easier viewing open the images in new taps and swap between them. First up is the 3000W V3. Easy placement as expected, lots of available frame to weld to. Stock sprocket position is maintained. QS138 70h V3.jpg The 4000W is roughly the same outer diameter but the centered output mea...

Pretty sure they have drawings of some of them; you could print those out and use cardboard-aided design with your actual frame. ;) Does this count as cardboard aided? :wink: 138 V3.JPG Check my rieju thread for reductions - I could fit the 138 motor sprocket in the same place as original motor spr...

Couldn't you just change the rear sprocket, or the motor sprocket? Or is there a chain clearance problem somewhere by doing so? I need to get CAD models of the motors and chuck them in a frame to see if there are clearance issues. What are my odds getting them from QS? I have a feeling drawing them...

I don’t think two-stage reduction is needed, why do you? Why do you think the motor is limited to 72V? The main reason for wanting a two stage is being able to change/play around with ratio's at will. Its more work setting up a jackshaft but I think I would rather have the ability to use 'standard'...

Hello, I have been wanting to start a conversion project for a while now and recently managed to pick up a suitable donor at a decent price. 1.jpg 2.jpg The previous owner had the top end blow out mid 2019, he put the registration on hold with plans to rebuild the engine. A few years passed and deci...
