Re: Tire slipping on rim causing valve stem to tear and or flat

Maybe some of the tips in this thread would help my situation? Finished building my wheels, but can not get my tires to stay seated to save my life. Using CST Cyclops tire on DX32 rims. Going tubeless. Have managed to get them to seat about 3 times and hold air, but they leak down after a few days, ...

Re: Questions about ebike rims

... I plan to use Cliffhanger rim with 18 spokes on the non-drive side and 36 spokes on the drive side, with Wheelsmith DB14 spokes. I will have to drill and extra 18 holes in the rim and hub. What? Wouldn't that make the rim really unbalanced? Never heard of such before. I'm intrigued. Please shar...

Re: Stongest tandem ebike wheel build help

What is the reasoning for drilling out the eyelets and using washers? Is it because the washers can rotate, whereas the eyelets are under strain from the twisting forces of tightened spokes? Yeah, the hookworms have been one of the highest recommended tires for this setup. Also the Cyclops tires, wh...

Re: Stongest tandem ebike wheel build help

The DX32 is a good upgrade from average MTB bicycle rims when you need stronger and wider, but for those disciplines where we need the strongest rims, it is low entry level. ... :cry: Well, that sucks. I was under the impression the DX32 was much better than that. The only issue I was aware of was ...

Re: Stongest tandem ebike wheel build help

Where was all this advise when I was asking for help with building a heavy duty wheel? ( grumble grumble ) Anyhow, after thinking on it and researching over the last year, I went with a pair of Alex DX32 36h rims. From what I could find, these rims were pretty well regarded, and I only found just a ...

Re: Could use some advice on paralleling two controllers.

No, I have one of those Cyclone 3kw mid-drive kits. Plan was to buy a couple of those cheapo Sunwin controllers (preferably the 12fet), and experiment with them. As cheap as those are, I am not sure if they have much of any protection. Spinningmagnets is right though... can't prove/disprove my parti...

Re: Could use some advice on paralleling two controllers.

Ok cool, thanks for the feedback. Shame it did not work out, but I have a theory. When you connect both controllers to the same 3 phases and halls, and apply the throttle, both controllers are going to try and start off on whichever phase the MCU chooses. This results in 2 phases receiving power at ...

Re: $14.99 72v Sunwin Controller

I think that is a different scenario to what we are discussing here.

Idea is to use 2 identical controllers to run a single motor.
Both controllers hooked up to the same 3 phases and set of halls.
Single throttle Y'd and providing input to both units simultaneously.

It didn't work at all, at least on the controllers I used, even with only one powering the Halls and throttle. Can you tell us what happened? Motor will not spin up, extreme stuttering, overheating, or controller(s) go pop? Asking because I am interested in trying this myself, albeit with 2 identic...

Re: Building a robust rear wheel for a mid-drive

The rim and hub I have chosen should be more than capable of holding up to the abuse. (Alex DX32 36hole rim, Novatec enduro hub) I am more concerned with spoke choice for such a high power application. As I explained in the OP, Sheldon Brown mentions that some wheel builders opt for stronger and som...

Building a robust rear wheel for a mid-drive

Alright, so there are many threads about wheel building, but I have yet to see any of them that pertain directly to building wheels for mid-drive setups. Most of them discuss building wheels with a hub motor. With the high torque forces applied with some of the more powerful mid-drive kits, building...

Re: $14.99 72v Sunwin Controller

I am with you guys on thinking that 2 controllers in parallel would never work. I thought it would fail catastrophically, either with the phases not being in sync, or one controller backfeeding into the weaker one. But some time ago, I read someone claiming that they were using 2 controllers in para...

Usually for these controllers there's to-92 case voltage regulator which is capable of putting out up to 100mA. Thanks for the tip. I'll have to pull my controller back apart and look for that component. I did try to trace down the regulator when I had it apart before, but was unable to locate it. ...
