CYC x1 Pro on 2014 Giant XTC Advanced+ BB92 w/ Adapter?

[SteelWolf]

First time poster, first time builder, I have been trying to make sure I am getting all the right info without posting a new thread but now am nervous but really want to pull the trigger on a GNG CYC x1 Pro 3000 watt etc, (though I only plan to start with a 36v battery anyways most likely so the 3000w is not a deciding factor, access to info, build quality, expand-ability, dependability, etc is...)

I have a Giant 2014 XTC Advanced+ 2 27.5, I got it for a steal on ebay, almost unused, but realized that I had gotten the wrong type of bike, carbon and press-fit BB92, for my ebike dreams ( https://www.giant-bicycles.com/us/xtc-advanced-27dot5-2-2014) ... But there in come adapters, https://lunacycle.com/pf-41-adapter-for-pressfit-bottom-brackets/ (Is there a better bb92/pf41 to bsa adapter out there? please share!), at this point I am hoping I can use one of these Luna adapters and get a CYC X1 Pro 100mm (Or do I need the 120mm??), and I have come to you all to ask if you think this will work out? I have had many emails back and forth with https://lift-mtb.com/ and they pretty much guarantee that their v3 motor with their adapter will work on my bike but it is a brushed 450w nominal 750w etc, and I want room to expand the power as I am 260lb 6'5 male and live In Los Angeles CA and want to commute over all those hills to work as well as do some trails.... Does the adapter w/ the CYC x1 Pro work? Am I asking too Much? Are there other issues cause I have a carbon frame? I read and read posts, watch youtube, and still I dont know what to do. I think for $950 or so the x1 with its power and newer design may trump the v3 but the v3 is French/Euro made so quality over power? There is little or no info I can find on the V3 and it seems everyone is doing fun things with the CYC x1 this year and it still is "discounted" Please help, mostly I need to know if I can get the CYC on my Giant XTC, do I need the 100mm or 120mm, and what adapter to use? Ill worry about batteries and all that later...? Please Help, Mod if this is wrong place very sorry please move it or let me know what to do. Sorry for the rant. you guys are the best and thanks in advance!

Or will this work? I just realized the Luna are not threaded... https://www.ebay.com/itm/J-L-BB92-BB86-BSA-Bottom-Bracket-Conversion-Adapter-Convertor-/301825746922 these are and are the only ones I have found...

They will be coming out with bb92 in a month or so. Or use adapter. But for you it is better to wait. I have bb107 and that will only be out in 2-3 months so I will be using that adapter in the meantime.

That is great news! Did they tell you that? Is there any info posted anywhere online? Thanks so much!

Now can someone refer me to a page where I can learn about hobby batteries? I read several to do with watts, AHs, etc, but now Im reading everyone referring to 82 Lipos, 14s, etc and when I go to the links I have trouble making heads or tails of exactly what Im looking at? Thanks so much for all the help, I know I should be searching the forum more and I am reading but finding specifics without jargon that gos over my head at times can be very frustrating. Oh and what kind of plug would I need to connect to a CYC x1 Pro? Do most ebikes use the same plug, or come without one, say Luna and other sellers? It looks like the good hobby suppliers like maxamps (I assume they are good since I have seen them linked here) let you choose the type of connector and its a long list... Thank you again.

Develop strong google fu for the jargon, that's 90% of it, the maths are usually basic

Closely parse posts over your head, google with the special keywords like OR, or site: on different forums to get well-rounded info, e.g.

https://www.google.com/search?q=site%3Aendless-sphere.com+termination+voltage

https://www.google.com/search?q=site%3Arcgroups.com+node+charging

if googling doesn't help, ask for help with specific Qs, don't be afraid of looking ignorant, we all started somewhere.

Any word on how much the CYC X-1 weighs?

Similar to a bbs02 (including outer reduction), both including cranks/display/throttle.

There is allot to learn about Hobby Lipo Battery's
Too much for me to explain so I will condense most everything as much as possible , and still stress some major points .
Much I write below , I found out by personal experience .

1) Always Charge Lipo's outside

2 ) Build a battery bunker to house the batteries ( Cement retainer blocks work well for this, put on top of thick large paver stones

3) Charge at a 1c charge rate. ( If you have a 7s battery pack and it is 5000 mAh , then charge it at up to 5 amps , If you charge two of those packs in parallel charge at up to 10 amps

4) Buy a very large Power Supply ( 750-1,200 watt ones ) ( Modify a HP Server Power Supply , check youtube for this )
https://www.youtube.com/watch?v=Fmdbhih2G4U

Do Not ! do this to increase output voltage , ( they will only safely go up to 12.7 volts ) I include this video so you do Not do it !
...https://www.youtube.com/watch?v=4P1-lpzYV1Y
( Note : instead of shorting two points on the board, the way to increase voltage from 12.28 to 12.6/7 is to just turn a very small pot , it is different on the 750 watt one from the 1200 watt one )

I think this is the right way to make a 24 volt P.S. from two HP Server P.S.'s ( but why , just spend the money for a iCharger and or get a Meanwell 24 volt )
https://www.youtube.com/watch?v=d7lF1sIgIlA

A quick search does not show me the correct way to adjust the voltage from 12.2 volts up to 12.6/7 volts.
I can find that latter if you do buy the HP Server Power Supplies instead of buying a Meanwell 350 + watt 24 volt dc power supply .
The Meanwell's are much more expensive that is why many in the Hobby world just modify a HP Server P.S.

It is best to Not series 2 HP power supplies to make 24 volts, as you can see it is a complicated hack or at least a hack that must be done right , J. Bardwell , the third video I linked to looks to have done it right , but even one person on the comment section said not to isulate the 3 screw , so ? . ( have I talked you out of series 2 Power Supply's yet ? , it really is best to just get the 1200 watt one and a iCharger )

5) Buy a very large wattage charger ( 500-1000 watt )

6) Discharge the pack/s at up to 1/4 or 1/3 of what H.K. says is the discharge C rate

7) When Charging packs find out the max charging rate by the pack ,
Example : 7s x 4.2 volts max = 29.4 volts, now since it is a 5 amp hour pack and you are charging at 1c ( 5 amps ) you now times 29.4 volts by 5 ( amps ) for total wattage of 147 watts , now since you have 2 in parallel then you will be wanting a Power supply and charger that will charge at least 300 watts or better .

8 ) Most power supply's only supply wattage that it is rated for if you are using a 220 volt AC input , So , if you live in the U.S. and get a power supply like the HP Server that is rated at 750 watts then count on only 375 watts of power from the P.S.

9) DC chargers mostly only charge at the max of their rating when they have 24 volts or more DC imput ( or the near the max DC imput that they say on the Specs page ) For instance iSTD8 that says it will charge at up to 1,000 watts will only charge at half that when connected to a 12 volt power supply .
Add to that the fact that for some strange reason the iSTD8 draws so much power from the P.S that there is a voltage drop and for many P.S. 's they cannot handle that . ( I have to go in and adjust the Pot on the HP powersupply's to as much as they output which is 12.6/7 volts . Then the iSTD8 will work )
Note : iChargers are more expensive than the iSTD8 but they will operate on a lower voltage than 12 volts like the iSTD8 , they will operate on down to 11 volts so that when you have a voltage drop they will still work with any Power Supply.


Someone said on the X1 Pro thread that they are only getting speeds up to 30 mph on a 14s pack ( in the case of Hobby Lipo's that means two 7s packs in series )
So if you want to go faster then you will need three 6 s packs in series , or four 5 s packs in series for 72 volts

Now can someone refer me to a page where I can learn about hobby batteries? I read several to do with watts, AHs, etc, but now Im reading everyone referring to 82 Lipos, 14s, etc and when I go to the links I have trouble making heads or tails of exactly what Im looking at?

In Regards to which connector to use when connecting a Hobby Lipo pack to the controller ( any controller on any DIY system )
you will have to learn how to make your own wiring harnesses and how to solder them to the connector you will use .
Plan on a few hours on Hobby King to find all you need
Solder
Soldering Iron
Wire ( 12 or 10 awg ) and plenty of it !
Connectors
Soldering Jigs
Etc.

Most batteries that are larger packs 5000-20000 mAh packs from H.K. these days use the XT 90 connector.
You will be making parallel and series harnesses , for both charging and discharging ( operating the e-bike ).

For the connection from your home made harness from the pack to the controller , use the special " Anti-Spark " XT 90 connector.

Thank You all for such great info! Esspecially all the tips and info about LiPOs; I need to digest it all but not have been at the computer for health reasons. But Ill be doing more tomorrow and I am sure I will have more questions. Thank you so much everyone!

Anyone have any more about the Bb92/PF41 version of the x1 pro and when they are promising to release it? And do you all expect there will be problems and delays with these new ones?

Thank You
ED

You will have all your questions answered in the cyc owners group on fb, just search the term pressfit. They have even teased some pictures of it privately. I think they will be done in the next batch that should go into prod in 1-2 weeks.

I thought I would post an Update for all those that helped me; My CYC X1 Pro Kit was shipped yesterday (I purchased and have been in contact with them all these months)
I also purchased a EM3ev battery, the 14s7p Cube with 35e Cells and Smart BMS with the better charger and 90% cut off (Not the $300 smart charger, i simply cant afford it, mybe after i make some money on this bike, but I think a second cube to run parallel for increased range and amps would be more useful; if anyone wants to buy me one for my birthday on Jan 8 Im not too proud to refuse, LOL, PM me, ;D)
Thank you so much for everyones help and encouraging comments, i will be a continuing member here and will be making build videos and reviews! Love and Respect and Successful Builds wished for all in the coming Year!
