Shunt Modding the Wired eBike

In this video, I shunt mod the KT contoller of the Wired Freedom to give it more power and test the results on a hill climb.
Front motor kits can be found at www.citizenperformance.com/

For those curious, the shunt mod takes two resistive connections that are meant to reduce strain on the controller components, and bridges them together to increase amperage. It's a common mod and usually safe, and the KT controllers are fine with it most of the time because their output transistors use the controller housing as a heatsink. The power increase is about 200 to 300 watts, but does not show on the display because the controller calibration does not account for the change 😉 The battery discharge current is controlled by the BMS (battery management system), and will limit how much power the controller can get. The exception of this is the BMS is mismatched, defective, or uses direct output which is unmanaged. If the battery or controller show signs of overheating, you can "undo" this mod using the soldering iron and solder wick, then bending the wires back apart if they are touching. Have fun!

[@CitizenCycle925]

Thank you, you are a wealth of knowledge! Always insightful comments 👍

[@notsoanonymous2458]

"The power increase is about 200 to 300 watts..." Is that relative to this bike, its battery voltage and controller amps or just in general? If I did this to my Emove Roadrunner, which is 48v with a front controller of 15 amps and rear controller of 20 amps would I still see 200-300 watts per controller? That would make a huge difference vs the Wired Freedom.

[@Werk4Cash]

What if a controller only has one bar instead of two?? My kugoo m4 controller only has one bar and appears to be missing the second bar from factory

[@r.vargas5410]

​@@Werk4Cashyou can still do it , I wrapped copper wire around mine and then soldered it , sounds like you have a 22 amp controller,I recently upgraded my controller to a 30 amp ,but haven't done the shunt mod , I feel it doesn't need it , it has plenty of power as it is .

[@Werk4Cash]

@@r.vargas5410 ahh gotcha!! I tried just putting some solder by itself on the single bar and it appeared a lot faster but forgot to unplug the battery before putting the controller back in its housing and it caused massive sparks and shorted out. Tried unplugging the battery and reconnecting it and the damn battery wires sparked so much they basically fused together and crumpled apart totally messed up my kugoo m4 pro :(

[@CallMeHarris]

WooHoo! Did this and it is absolutely quicker!! This is an A+ mod! Thank you for sharing

[@jasonkrantz8946]

Did it get hot from shunt mod

[@user-xk3bu6rw7z]

Thanks for the videos! Gained 2mph and a bit more torque 😉

Always!

[@davidgraham2673]

YES

[@johnhecht5565]

Thank you for the great video. Shunt mods, dual motors, dual batteries. How fun is all that? Can’t wait for your next project.

[@CitizenCycle925]

Not sure what next project will be...

[@user-qs8lj7ql3h]

My own experience on my shubt modded 2024 Wired Bike: seemed to pickup a few watts in lower pedal assist. For instance Pedal assist 1 used to be about 230 watts now its 250. I had a hard time riding under 18 mph in pedal assist 1 now. Bike just seemed to have a bit more juice on the same setting. Off the line power a little more snappy, the top end I hit 41.6 peddling with full throttle on flat with no wind so maybe 1 mph gain or so on the top end. Based on this a worthy mod and its probably not going to affect any reliabilty

[@chuckas57]

Another Great Video

Unbelievable, ORDERING TODAY

[@CitizenCycle925]

Awesome!

[@boblaturner7427]

Hi Citizen, I really like your videos... This first I've heard about something like this, what is it actually changing in the controller? Also, can this shunt mod be done to controllers in other bikes? Thanks.

[@CitizenCycle925]

Yes can be done to other bikes with KT controllers, I may do to my grizzly controllers too, I think they are KT. If you read Altema22 comment he explains better than me 😁

[@kdscrapping4452]

Have you seen the UBCO 2x2 ?? Any thoughts ??

[@andrewford9974]

Fun. Until the bike stops working because the mosfets in the controller overheat and melt

[@LeeAyzahn]

the hand shake with the pedal 🤣

[@CitizenCycle925]

Haha, you caught that 😃

[@CONSCIOUS_TALK_ENT.]

That may make the battery terminal overheat if you feed it more power. My battery started melting the inside terminal and I didn't even do a shunt mod.

[@avonstellar4475]

Can you review the new ecells five star bike? I heard it's on par with the wired freedom

[@IMBruceECLECTIC]

Great job! What's up with the bike laying down at your starting line...?

[@CitizenCycle925]

Not idea, it's been there for like 3 days.

[@IMBruceECLECTIC]

@@CitizenCycle925 ...that means you live in a nice, crime free area. :) I am going to try the shunt mod on my GOAT bike....You made it look easy. Do you think "liquid solder" would work?

[@anio6865]

So, if I use rosin core wire, I do not need to apply flux beforehand, correct ? And I do not need to heat up the shunt correct ?

[@petemiddleton64]

Wonder if good fan will work to cool it

[@duanehundley]

If you change the controller can you run a 72V battery for your front motor kit? More Volts=more MPH

[@CitizenCycle925]

I would not, it's a 52v motor so 72v is probably too much juice

[@Ebikepowelevel5]

I know this is off the subject but I got a e mail about a bigger battery with your kit and I was curious as to how much bigger the 20 amp hour was over the 15 amp I wanted to make sure it will fit in the bag with your controller

[@CitizenCycle925]

20ah is 180mm x 170mm x 75mm and 10lbs, the 15ah is 180mmx 150mm x 75mm and 7.5lbs.

[@leviboyton1707]

Would this work I’m running 52v battery 23a and a 48v controller

Can I install a dobble crown fork from e-cells five star e-bike to my wired freedom 2024?

[@keithpegg7825]

Thanks, the mod was fun and would like to read more. how about a higher output controller? I do know that CA Cycle Analyst have done some testing with e-bikes power, my first build 9 years ago was with CA and a 1000 watt drive had a lot of fun and 16,000 miles. sold it last year. Have a new bike now lower watts but just as fun. 75 years old and enjoying life.

[@jwillwork3683]

Can you do this with aventon Aventure ?

[@snapshotprophotobooth1864]

I ordered the motor kit about 1 1/2 weeks ago whats your turn around for orders. also can this shunt mod can be undone if we don't like. just desolder?

[@CitizenCycle925]

Kits are still being manufactured, I anticipate shipping out to customers in May. Yes, You could undo the shunt by desoldering.

[@user-qs8lj7ql3h]

Did you notice any wattage max difference on the screen that you could read vs stock?

[@CitizenCycle925]

No, you will not see it reflected on the display watt meter.

[@Goesriding]

Good job. A lil chintsy on that solder tho lol

[@rustymeyers1]

Can I do this on my rad rover plus?

Can I do this to my area 13 controller for rad rover 5 upgrade?

[@CitizenCycle925]

Yes, I did mine. That's what is on the rear of my Citizen bike.

[@SCIFIBRITHEVIDEOGUY]

@CitizenCycle925 ok. I haven't upgraded the motor yet. Do you think it's OK with the 500w Motor?

[@Busdathead]

As always thanks for all your valuable input on everything especially "Wired" ! I don't know if you truly realize how influential your bike reviews and testing are to us who live in an ebike desert ! All because of your reviews I've bought my ebikes , first one was a Hiiwiway cruiser (I loved) I owned it until I realized that it accelerated way too slow to run with traffic . Here in Indiana cars will just run you over or off the road while they curse at you(f____ing idiots). I was really excited with your review of the wired freedom and it's top speed so I bought the late 2023 model and really wish I would have waited a few months for the 2024 model because I can't take advantage of the mid suspension , it will rub against my controller box so I have to extend it all the way out to avoid this . I have plans on buying the new model that way I will have spare parts and battery if needed . You are truly "De Man" 🏆on all things ebike related , keep up the fantastic work !

[@CitizenCycle925]

Glad to hear you are enjoying my channel! FYI If you buy a new wired the batteries are not interchangeable. They change the connection port.

[@TurntDreeze]

Can you purchase the screen for any bike?

[@maxhughes5687]

Great. Get ebikes outlawed in my home town.

[@ollieox9181]

You really should add the caveat (or, maybe you did but I missed it) that modifying a bike this way might void your warranty. Also, a lot of states/provinces have speed limits on ebikes in public areas. So, anybody looking to do this modification, be aware.

[@pensbyrob]

How much is your front hub motor for the Aventon adventure 2?

[@CitizenCycle925]

$899 for complete kit (motor,controller,wiring harness, display, throttle, battery, charger )

[@pensbyrob]

Thanks I will be in touch in the near future.

[@bobbybecker80]

I'm surprised the controller is encased in a plastic box as that inhibits cooling (IMO).

[@mikey3239]

i was thinking the same thing i drilled several holes in my box dont know if it will work

[@indogyrsimdead]

Just paint the controller black and Zip tie it to the frame

[@ringss12]

Will this work on an August 2023 cruiser also?

[@CitizenCycle925]

Yes

Poor 5 Star and their potted controller! No Shunt Mods for You!

[@johns5504]

Thats exactly what I was thinking

[@quantumfx2677]

Yes, can easily be done on the 5 Star however it voids the warranty. It increases the power the controller provides to the motors and also causes a lot of heat because the controller is not designed to handle that much power

[@tylermckie5322]

How much is a new controller if you break it??

[@CitizenCycle925]

$139

[@Ekamwitu]

does this breack the bike or over rule any warrantys?

[@CitizenCycle925]

Absolutely voids the warranty

[@Ekamwitu]

@@CitizenCycle925 oh then ill just do it after the warranty ends

[@SciD1]

I have no idea what you did in that controller. But didn't look like worth the risk of messing up the controller.

[@johns5504]

My bet is this is next to impossible in a fully insulated controller ?

[@CitizenCycle925]

Correct, can't really do this to lishi controllers.

[@blueCollarGuy]

Your next video should be a dual motor shunt mod. Need to see that video. Show a temperature reading as well.

[@DrRevKing]

Good demonstrative video, Brian. But me and my 2024 Wired Freedom's warranty are going to have an excellent long-term and lasting relationship without it. 😂 Plus, your front wheel ROCKET kit is all this Flash Gordon-era fan needs to "CONTROLLABLY" blast off to exfil or infil True Believers out of Harms Way for what God may allow. Thank you ! 😊

[@CitizenCycle925]

Yes this definitely voids the warranty, glad you are excited for the kit, can't wait to get them out!!!

[@DrRevKing]

👍

[@Mike6string]

The five star from e cells just took 75% of wired’s business 🤣

[@shawnchambers3416]

WARRANTY = GONE

[@jpmyles1560]

I want to make my Xclass 52volt faster

[@mikey3239]

dont think this is good for the controller long term ,

[@CitizenCycle925]

Definitely voids warranty, I've done it to other controllers and they have been fine but it's running more power than designed for.

[@indogyrsimdead]

The only problem I see in doing this Is how does it affect the range? more power usually means less range

[@markcozzie]

Not possible carrera ebike 100%

[@djdocbear5603]

So far my is going slower

[@BigEightiesNewWave]

Needs a soldering lesson. The idea is to heat the wires, that are going to have solder pushed into the heated wires, so it flows into the wires. This is so cringe.😂 His is literally dripping melted solder onto room temp. wires, then a big blob, lands on the PCB
