This is not an ebike specific question, so you can use a regular bike calculator.

Higher frequency favours multi strand wires. So the more strands the better for mid drive. Usually multi strand wires are softer.

More connectors are usually put for better power transfer. Load better spread = lower temperature.

Both sides of the connector have to have 4 for it to matter. So 4 on one side + 2 on the other = 2 connectors.


In short, NOTHING CHANGES.

It depends on the connector, it's capacity, and the system power.

It will probably be ok with a 250w motor, but most 250w motors aren't actually 250w.

If you want a real refund, either contact paypal or if you paid by credit card contact your bank and file a chargeback claim.
You will need to supply evidence on you sending the package back and the seller recieving it.

Argh. I was looking at alternative to spot welding. To use the epoxy to hold contacts in place. I've found a few more older threads about it but none cover the connections. They're all SW.

Oh wow, OK.

Does he spot weld them before though?

Yes it is spot weld like any other. BMS goes in and gets filled in too.

If you are making it for someone else, make sure it is either rain proof, or that they understand it isn't.

No need, epoxy is already insulating, in motors they use it in addition to motor varnish.

Guy in UK already does them to order. Also makes the pack vibration and water proof. (Luna wolfpack is epoxy filled on the inside too.)

Yes you can string 3 SLA 12v batteries to get 36v. They charge slowly though. Good for 30km.
300km a day if you can't afford $250 is a fairy tale though.

So far segway's own business efforts have been a giant failure so I really don't expect them to succeed this time. Even with the sur ron to offer they can very well fail to meet the customers needs like they have in the past. Segway has been bought by ninebot, they are 100% in chinese hands, and if...

Definitely looks like the wheel would bump into the battery on a big hit.

You are not supposed to plug and unplug the controller every ride. Use the ignition switch or display on/off, or battery on/off switch. All of these are low power switches and will not degrade after hundreds of cycles. You can use the battery switch to depower too if you take it off for charging.

Don't go centrelock. They are a lot more expensive and no cheap alternatives. I would easily choose a different hub if I had to, proprietary standards suck.

Thanks to the site and all of you!

What speed do you get with the wheel in the air?

Yes you are right, but 35A will be different wattage at different volts right? If my battery is fully charged so 58v, controller pulls 35A that will be 2030 watts? But under a 35A load will the voltage drop, meaning my wattage will drop also? I know amp draw will be the same. Watt is a consequence ...

Hi I have purchased this ebike kit - https://www.cloudsto.com/ebikes/kirbebike-conv-kits/kirbebike-1500w-2000w-ebike-kit-inc-ion-plus-58v-17ah-battery-457-detail.html I seem to be struggling to find a battery. I would like the style that mounts to the bottle holder mounts, but most state maximum po...

For 12.5A per cell peak you don't need high drainage cells, you would be fine with high energy cells too, like 50e. The 40t can do 25a cont and a bit above it peak.

If you are going to go trough the trouble of replacing it, DNM is not much better, not worth it.
If you are replacing it get a used rockshox boxxer, marzocchi bomber 380 or fox 40 on pinkbike.

Would be nice to put the cyclone or similar motor inside the lower part of the battery case/box. The prices of the stealth bomber eBay knock off etc. frame have come down considerably. Still no taper headset and only small wheels are useable and it’s heavy. A lot of dual crowns have non tapered so ...

I found out about that Cyclone 4.8 kw motor and frame just a month or so after I bought my GNG 2019 3000w motor,

If you already have it, it is a done deal, the GNG drive has most of the cyclone kit's bugs fixed, so it is as good as you can get otherwise.

There is no comparison.

5.2kw hub vs 7.2kw hub vs sur ron hill climb:

0C5hlyI6F1E Cyclone have their own integrated swingarm. Much better than even the lightning rod version. It is $700 including motor and controller. I showed it to OP in the cyclone thread, he wanted nothing to do with it, he wants to keep his swingarm. So because of that, he would rather suffer wit...

Maybe a mod can revert this idiots posts so the discussion makes sense again.

Rather not buy another swingarm..just looking to see people who fit a standard 3000w on an EEB This setup gets around a lot of problems and headaches a mid drive would otherwise have. If you want to do it right it is well worth it. I certainly would. I've seen some people install bbshd on qulbix an...
