Re: QS MOTOR,0.5-14kW Electric Hub Motor Manufacture China

Is there an ebike version of the 273 v3 motor? I'm looking for a motor laced on a 19" moto rim with a chain sprocket on the side.

Re: E-Street Machine 20kW

As a guy who has previously assembled large hub motors in small wheels, I'll give you an advice that has proven to be priceless for me: Instead of going through each spoke --> wheel --> nipple, which makes it very difficult to attach the last spokes (specially on a 2 or 3 cross configuration), assem...

when that battery case is just right

I want to share the satisfying feeling I got when I received a random waterproof case I ordered online (based on specs only) to fit a 10p12s battery I'm putting together. https://uploads.tapatalk-cdn.com/20170202/ef9a763d8af85bc8d4d48f133824b65a.jpg https://uploads.tapatalk-cdn.com/20170202/f4e235a8...

Re: Fusing 18650 cells without soldering

Very good idea for non spot-welders as me!

Would it be possible to use a bunch of similar enamel wire as phase, just through the axle, in the same shrink wrap? Maybe even sensor wires wrapped on grounded tin foil...

Re: Anyone have front hub accidents even with torque arms?

Would it be too crazy to simply fabricate torque arms 100% with epoxy mass? Like a donut pressed on the axle around 1cm thick, which you could later drill and bolt.

Re: Brass for spot-welding 18650 parallel cell groups?

I was wondering if I could make P groups by simply sticking 1 or 2 layers of this cooper tape. They have corrosion protection and some have 2 sided conductive adhesive.

Re: Custom cruiser project

Well time to be sincere about the project and its shortcomings. 1 - rear suspension is useless by design. It compresses when I pedal and not when I ride a pothole. Everybody should be aware of this: suspensions should be designed to move up on a bump. Please don`t make the same mistake 2 - front sus...

Apparently my old bike got jealous of my new ebike and decided to throw me over the handlebars (or it was dark and I could`t see a massive hole in the ground). Busted shoulder.

Re: Adaptto Mini-E/Max-E Owner's Thread

You could use the existing switch to power a relay with two separate lines, one for the controller and another for the lights. You just have to find a relay that may act as 2 (or use 2 relays) .

IIRC brake input can be a hall sensor or a switch (e.g. Reed switch). The difference is that you'll use 2 or 3 wires.

Re: Tank cells ??

They could fit small kinetic he generators inside each cell as some watches do, or solar coating so you could just throw a bucket of them in the yard. Maybe little legs so they could crawl out and back in in the middle of the night. I would make them yellow and they would talk as minions... Lol
