    Upcoming Major Changes and Updates to the ES Site

    I'm very happy to hear all these new and welcomed improvements. That sounds ironic, coming from the operator that let the wiki die abruptly.

    Observed trials bike designing

    I don't think it will be extremely difficult. What is proposed here is to add some analog inputs, tweak throttle curves, PID values, etc. It isn't super low level stuff. I've a question for @owhite: What do you consider is the best commercial VESC based (open source firmware) that can handle...

    Observed trials bike designing

    Interesting conversation. To me is obvious that an open source and powerful controller will be needed to modify and upload custom firmware to try these ideas. Have somebody tried something like this in a motorcycle...

    3DE - 3D Printed Carbon Wrapped e-bike frame

    Subscribed! I've no idea what I'm talking about but... it may be possible to make 3d printed molds (using your current 3d models and substract operations) to create paraffine pieces, join them with heat and cover it with the composite. You can get out the wax if you want. If it works, this may...

    Magura brake pressure switch

    I've installed three of these on different brakes (shimano deore/zee, magura mt5) and never saw a problem like that (or any problem). Looks like a defective unit to me, probably the pressure actuator is stuck. Which brake/model brand are you using?

    Another Bomber/Enduro Clone

    Subscribed. Enjoyed the BMS presentation. Are you using cable brakes for that e-moto? No way put some shimano zee and other hall lever for regen. Stay away from those Zoom forks, they are just springs without any dampen and dangerous. DNM USD-8 are OK.

    A low-cost e-MTB Production log

    :lol: I don't understand how that motor and swingarm pivot work together. If somebody get a bike I would love to see detailed pictures.

    Thanks pal. On my dirt bikes I use XT90 for all connections as they support 90 amps continuous. They are not easy to plug/unplug so it is not the best for a vehicle you charge every day. For light bikes I've used RCA or barrel plugs. These do not support more than few amps. I use XT90S anti...

    Salvaged Zero FXS motor converted to hall sensors

    Thanks pal. I'm very uneducated in electronics and only know the hall sensors of type: switch, latching and linear. I think all hall sensored motors use the switch type. Linear are common for throttles and never saw a latch type on an e-bike. The ones I got are...

    bluetooth BMS?

    I proposed having some naming conventions. While ago https://endless-sphere.com/forums/viewtopic.php?f=14&t=88676&p=1354972&hilit=propose#p1354972 Two years later I still find this thread very confusing. I think everybody means by now what "JBD" BMS are. (well labeled in PCB, same app, same...

    Yeah I've the same problem, bigger motors are too wide. Will require more "pancake" motors if want to keep the frame. I can build a new frame, you know the effort it takes, months or even years. I don't remember on which topic, somebody said the HPM3000B is not very good taken heat out. If you...

    QS 3000w midmotor

    Awesome idea to use the swingarm bolt to mount this motor. When I saw this motor version I was wondering how to mount it and your solution is great. What is the current weight of the e-moto? How many KW/h of batteries can you fit in? What chain size are you using? Where did you source the big...

    Not quite any standard I think. I stuffed the hub with 30x10x9 cartridge bearings and used this 12.9 grade bolt as the axle: https://www.mcmaster.com/91290a562 As I fabricate my dropouts I can choose any axle size. Maybe using 30x12x9 works for you...

    Exactly, not enough meat at that side of the hub. Your idea is interesting, but will require machining other piece at a very specific angle (because the inside flange is not perpendicular to the axis). For now, I've two hubs like these and they are enduring. Thre new threads are for the disc...
