    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...

    Questions about ebike rims

    What? Wouldn't that make the rim really unbalanced? Never heard of such before. I'm intrigued. Please share info about this setup.

    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...

    Stongest tandem ebike wheel build help

    ... :cry: Well, that sucks. I was under the impression the DX32 was much better than that. The only issue I was aware of was the potential weakness in the split and pinned seam. iirc, I only found 2 or 3 posts anywhere on the net where they had either bent or cracked. (1 cracked rim...

    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...

    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...

    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...

    $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.

    Could use some advice on paralleling two controllers.

    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 identical controllers purchased from the same manufacturing batch. Hoping they would be closely enough matched to...

    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...

    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...

    $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...

    $14.99 72v Sunwin Controller

    Prices on these seen to have gone up. I am trying to find a suitable replacement for my Cyclone 3000w. I am considering 2 options here, but not sure which way to go. - Get the 15fet version (18fet would be physically too large), and try to beef it up. - Or go with 2 identical 12fet controllers...

    new cyclone 3000 w mid-drive kit?

    Anyone have a dead 3000w Cyclone motor that I could steal a part from? I need a back cover for an experiment. And also hi everyone. It has been a while. :D

    new cyclone 3000 w mid-drive kit?

    Hey Mark, did you try unplugging the ignition wire connector at the controller and short the pins together? Talking about the 2 red-wire pin connector. Unplug that and short the pins together, see if it starts up. (Just remember that is FULL battery pack voltage running through those pins) Don't...

    new cyclone 3000 w mid-drive kit?

    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. Maybe I can figure it out this time. It's the stock controller that comes with the Cyclone 3k kit (the...

    new cyclone 3000 w mid-drive kit?

    Greetings Gents, it's been a while. Good to see this thread still ticking along. Quick question. Has anyone added a fan to their stock Cyclone 3k controller yet? I've been searching for a few weeks, but have not been able to find anything via search. My controller is the SaiKeLong 400...

    Big sale day for China tomorrow (11/11). Save on Ebike parts

    I was planning on posting a thread early this week to see if anyone knew about Black Friday deals on Ebike parts for this year. Ended up getting busy and forgot to post. Low and behold, Micha posted a video about the upcoming China "Singles Day" sale to take place on 11/11/17. He outlined a few...

    Direct Drive Genesis

    Havn't had a chance to read through your entire thread, but have read several pages so far. Quick note: You said this is your 1st time buying on Amazon. I would go back and look at your purchase and see who the seller for your charger was. Amazon does not sell everything direct, as many 3rd...

    greenworks old type 40v battery.

    I don't know if I ever found anywhere on the net that showed the older non-Gmax pack internals. The Gmax version has a thread here, and some info available. You would have to pull one of them apart to see what cells are used inside. There are 3 stickers that you have to either remove or cut in...

    Only the poor want ebikes

    Honestly, It's a catch 22... (I'll make this into some bullet points to summarize) - Typically people who do not have much $$ express interest in buying an ebike. - Then they find out how much pre-built bikes cost. Obviously they begin to search for the cheapest ebikes made, which they do...

    DO NOT TRUST

    I'll just post this here... http://www.ebay.com/itm/152460358205?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT Just bought from this seller 1.5 months ago. He sent 2 rolls of 10M, not a single roll of 20M. Fine for my uses. Got it in a few weeks ago and verified it is real nickel...

    ON SALE TODAY ONLY $99. EGO 56v Blower(battery+charger+blow)

    Considering the costs in CA right now, that seems like a decent price. These 2pack 4Ah Ryobi's were $199 (US) just a few years ago. I believe it was Christmas of 2014 when they overloaded all of the HD stores with hundreds of these bundles at $99 ea. Following Christmas sales HD stores had so...
