Finally we have some custom Z1 content, mainly your DIY’s. Much needed in this community. Thanks for doing this!

This has got to be the absolute best z1 out there!

I just wanted to drop a thanks, I finally did this mod after my Super73 battery took a crap ( confirmed that it had dead cells). When I contacted Super73 they wanted to charge me $600!!! After just staring at my bike for a couple of months of just staring at my useless bike I bite the bullet and started this upgrade. I had a few hiccups but It's now running awesome!!

Great mod, It's been working great for over a year no issues. Motor seems to handle it well. Yours is much cleaner!!! Great video

Super73 should take notes and make this Z2 version. Thx for posting.

I tried the speed hack by cutting the white wire like some youtube video suggested and it fried my controller. Use my multimeter to check the controller and found out by cutting the white cable, five mosfets inside the controller are blown. So I decided to fix the bike myself and tried this upgrade shown by Rick. It took a couple of weeks to get all the parts in while my Z1 sit in the living room sadly, staring at me. When all the parts finally arrived, I went to work and lo and behold, the Z1 is repaired with new LED monitor, new throttle that's very responsive, and new controller. The one thing I did not do is swap the battery because the battery I purchased from China is too long to fit inside the seat. Now my bike runs normal again. I achieved 20 mph with the stock battery. I am going to add a second battery, the one that did not fit, into a new housing and use power switcher to switch one battery to another. That way, I have two batteries on my Z1 when I need to take an extended trip. This new controller is able to automatically detect the Volt on the battery and adjust itself. Thanks Rick for sharing this very valuable video with the community. I replayed this video probably 10 times while going step by step process of fixing my Z1.

This is super helpful!!! Very detailed and at the right pace. Very easy as long as you have some basic electrical skill. Thanks for taking the effort to making such a high quality video.

Awesome video the community is forever in debt to you! 🤙🏼

Just did the his 48v upgrade and my z1 is scary fast and torque great

just did my swap on the zg (EU version) and it works perfect tutorial helped very much

Awesome to see some DIY content! I subbed to you in your esk8 days. Love the look and feel of the channel!

awesome vid Rik! Lot of work to do this. Can’t wait to see the performance video, this would be a great project for my Z, thanks for the indepth step by step video

Which I would have looked at this before cutting my Z1 up and going for it lmao!! Great video!!! My mod keeps shutting down it cuts off and my motor is like struggling to keep the throttle going

Such a well done video !!! Keep it up brotha can’t wait to see more mods

Going to do my conversion tonight without having to research what needs to be done. I am forever grateful for this tutorial, thanks again brother!

Rik. Awesome job. Thank you. Keep up the good work. And say mahalo to your other helper. Awesome bro

Good Job! I'm thinking about taking the plunge. I wanted to leave it at 36v though. Waiting on your test vid

I have a z1 i have hardly touched since 2022 and want to know if this upgrade is still the best option in 2024

bro that was awesome. thank you

Big ups to karacold!!!!

The brick lithium site is offline. Is there another option you are using for the battery replacement?

RIC...on the controller I installed, the wires are the same as your tutorial. The install went great,.. but now. I bought a bigger one ( sine savaton 1000 to 2000 watt 45 amp- universal voltage. 36 volt to 72 volt). It's missing the white wire on it's hall sensor grouping. Someone on Facebook told me that missing white wire isn't needed because it's for temperature semsing.

Awesome videos! The link for speed controller/lcd is no longer available. Do you have another? I’d rather purchase the right gear the first time 😜

Awesome vid. Would love to see the pedal assist install.

You’re awesome man! Thank you for this vid! One question- For the programming, how did you get the numbers for that? What would I have to enter for the C sections for pedal assist?

is there a new link for the battery? I can't find the one in the video using the link in the description, also can a 36volt motor/hub handle the 48-volt battery?

"That' coming right up!" ;D

Is there a different thumb throttle people are using? the one on here is out of stock/unavailable :(

*Dude?! wish I wasn’t 6’3* because I’m way to big for SUPER73’s bike frame’s 😔 but this was complicated but you must be an engineer by trade because that was awesome! I could use a little off-road setup like this to take to my secret 🤫 fishing honey hole’s. I wonder if they sell a fishing rod holder for this Lol 😝 Honestly, everything seems really custom and DIY so with a bit of creativity I bet I could rig something up. *I love the look of the Super73-RX frame with the dual shock’s... it’s probably my favorite frame even to this day* Wish frame wasn’t so low to the ground because at 6’3 199/lbs… I don’t see me being able to pedal this without looking like the Jolly Green Giant who keep’s kneeing himself in the face while trying to pedal on this sweet a$$ frame piece🤣. Seriously tho, I really think the Super73-RX frame’s are still the sexiest looking setup’s. I would love to hook up dual 1000w-motors with like dual 60V-20ah batteries, the open frame space would probably accommodate it somehow and with a boss-a$$ controller I’d be so smooth,pedal free and riding dead sexy!!! Awe man the possibilities with this frame!!!! I hope the *new Super73 CX-1 brings the frame up for taller rider’s?!*

Hey ,love the video did everything and my screen is saying motor position fault please help! @runplayback

As a first try you did OK. But... This is what I'd do, change the battery Voltage to a 52v (for me even higher maybe 60v) so you spend more time at 48v when discharging, remember Voltage is your speed and AMPs is your Torque. The amount of your AMP's is what generates any heat in your controller or motor. So higher voltage means same heat if you are using less AMP's to achieve the same Watt's (speed on the road). Voltage times AMP's = Watts or V times A = W (which) = Heat and Speed. Another thing to improve is the controller, there are only 3 types. Square wave, Sin wave and FOC (Field Orientated Controller) , its hard to describe but I have listed them worse to best. A square wave controller is like trying to ride a skate board up and down a stair case, a sin wave controller is like skate boarding a U shaped ramp and FOC is like surfing an undulating endless wave on a calm ocean. I can tell which you are using by the loudness of the noise being made by your electric motor as the more efficient will make less sound therefore square wave is noisy and FOC is silent. I won't bother with the first 2 as listed as you have probably encountered them already. The best FOC is sold by Grin Tech electric bikes in Canada, it is very small but depending on which model you purchase is about one third the size of your controller in the video. FOC features are much better and offer a wider range of voltages and AMP's, Self programming Hall wires so you don't have to "colour match", Regenerative braking (I have not bought brake pads for my bike for the last 3 years), and the motor I have is completely silent. I could go on and on about FOC but just watch their video's on their controller.

Hi can you put a fresh link to a newer battery option? That eBay link is dead

I put on the same controller and I do not recommend it because it heats up terribly, you can cook a dinner on it, do not buy it 500 watts too weak for this motor, I will add that it was only checked in the workshop without load. Video nice thx

Solid Tutorial bro! I don't have a super73 I do have a Hurley Mini Swell that comes stock with a 48v battery and 500watt hub that goes a max speed of 20mph. My question is if I was to remove my stock control panel and add this LCD Screen to my bike would I be able to go past the 20mph?

Hold on... The type of original controller in the Z1 is that : "CR M1000SP SP" ???? If so, then I've got the same controller in the EU version, which means throttle is possible !? No ?

Very detailed informative video. Super glad to see you help the super73 community out. For the programming of the controller does it come with information on each setting on what number to set it on? Also noticed you bought connectors also? What was it used for?

Awesome video bro. Best one I've seen in awhile. Extremely well detailed and you described every step perfectly. I have a Z1, so bow how much labor do you charge do this for me? 😅 - Phil

Nice vid pare! Ayo i want to upgrade my z1 with a 36v battery that fits in the seat. Any suggestions that fit? Thanks mane

Awesome video and thank you. Do you have to swap out the stock thumb throttle for the one you have linked? Also since the link expired. What other 48v battery will work. I’m Trying to purchase the whole set at once to get mine rolln ASAP. Mahalo 🤙🏽

Does it work if I just get the controller not the battery

I bought Z1 with upgrade to my son, but looks like controller died few days later. Is there any substitutes in Amazon or eBay I can quickly purchase? It will be super helpful

Hello what is the with of the battery

Hi there great video, would all these components work on the ZG by any chance?

Wat would I need to hinge me seat up like yours I'm just not ready for upholstery I'm more wondering how the hinge attached to the battery box

Hi man was wondering if you could provide a diagram of what goes where? As in which wire you used for the throttle. Plugged mine up and the LCD is good to go but it's not getting throttle. Thanks a lot for your help!

Thanks so much for this video helped me with my install. I was wondering where did you find out how to program the display?

Battery link is dead. New link?

This is great content and I'm trying to upgrade my son's Z1 with the controler you recommended. It seems like I will also need to replace the throttle and the brakes since Super73 has a different wiring schema than the controller. Is that correct or have you figured out a way to make the stock parts work?

You could just solder the motor phase wires instead of using the bullet connectors right?

hi, great video. do you know if this works on the eu version (ZG) aswell?

can you only put in the controller or will that not work

Is it necessary to upgrade the stock motor on the bike or is it fine with the new battery?

Man, one year later you’ve posted this video i just got my Z1 and one of my first impressions is that the battery should be bigger. Did you choose the 48V for a specific video? How big is that in relation to the stock one? I really have zero understanding of batteries.

How did you figure out the motor p settings? Did you figure out the gear reduction and magnet count?

What’s the battery? And where can I find it?

hey awesome video dude would this be compatible with the zx?

I had a question in regards to the throttle wires. I have 2 colors that do not match. Any ideas?

Hello. Nice Video. Just a question, I have made same stuff like you with another controller but not working ... I wanted to know if you need to connect too the brakes in order to works or or not ?

hi!! very nice video, i'm using it as inspiration for the mods i'm working on my Z1, thanks for making this detailed video. i have a question, the wires for the headlight of the controller, do you know what is the V output on those? if i have a 12v light do i need to also add a converter? again, thanks for the help. best

Hello. Nice video : ) I have made same think like you but when I accelerate I just the sound of the motor inside the wheel .. but nothing move. I have forget something ?

Watched every single video, thanks for the clarity. Question: if I wanted to replace the battery like you did but not the controller and keep the on/off switch, How would you do that if the aftermarket battery only comes with two wires?

Hello. just a question, this is not a problem if your battery is 1000 watts, when your controller handle less like 500 watts ? Not dangerous ? Can I use a 350w battery on a controller for 1000w for example ? And same about amper ? The battery delivery 20Ah, when controller rated current is 12Ah.

So how is the bike 4 months after the install? Does the battery still hold charge? Does it still have the same torque? Would I need a cooling fan for the my bike as it gets around 35°c over the summer?

This won’t burn or melt the 500 watt motor ?

Battery link is not working, any chance you could share the name or another link?

Rick another question, does the original 36v controler have a pedal assist connection, or a LCD connection? I want to put pedal assist on my z1 when it arrives in October....thx bro.

Maybe I missed it, but what is the T-plug to XT60 Adapter for? Love the content and informative guide. Looking to do this on my daily commuting bike and would like to make sure I got everything I'll need.

So in your measurements of the original battery you only measured the length and the height What’s the width? Or am I missing something? And also what exact connectors should the battery come with. It’s harder now because brick lithium has halted its production And I don’t wanna pay light speed bikes almost $700 for a battery that fits in the seat.

where did you get the battery

Would the controller you installed still work with the bikes stock battery?

What about the Super 73 RX to increase speed and torque? Would a simple Grinn Phaserunner on the existing motor and battery work for this?

We're do I find the link of the description of the parts. Also I seen on ebay they sell the controller and the throttle together would that work or I have to buy the one u have

Thanks for the video! I think my motor is spinning backwards tho. Can I just switch 2 of the phase wires?

Are we able to hook a up the same LCD speedometer up to the stock controller on the z1

What about going to a 52w battery? Would I need a new controller too? Di you think that would be a good upgrade or am I just going too far?

Ok RIC. I finally got my z1 with a dual voltage (36v & 48v) controller and a second 48 volt battery on the frame. I have pedal assist..l.c.d everything. Thank you for your help, but now I have a new problem. I bought a second massive controler...savaton universal voltage..can go 36 to 72 volt batteries..but, there is only 5 hall sensor wires instead to 6. .blue/ green/ black/ yellow/ red. How do I match these 5 to the motors 6 wires... Any clue bro?

Did this mod. Having a few issues. 1: throttle won’t read. I checked the wires like you showed in video and made sure the colors were lined up. (No throttle shows up on lcd screen) 2: lcd powers on when u connect the battery. U can use the control switch to go thru settings and turn it off. But it won’t power on from power button alone.

Would you rather buy a 73 Z1 and do this or buy a juiced City scrambler?

Where do I get the battery

I did this conversion and the bike keeps shorting out, asking around someone said it's most likely the settings (bike shuts off at 700W almost on the dot) anywhere I can find the what each settings are? I bought the same controller/screen but no instructions. Thanks!

How about leaving the opening open for ventilation instead of using gorilla tape? I’ve watched other videos too regarding overheating. What you think?

I wonder if this mod would work on my Ariel X-Class? Its currently pushing top at 28mph. It has a rear hub bafang 750w.

Is the throttle necessary, or can I just use stock...because I can’t find one with black option, thanks! The link has no more

Hey! Awesome video! 13s3p or 13s4p for battery? what is the difference?

Hey, I just got a used z1 and the battery after full charge only last an hour at most. Trying to change the battery so I can actually use the thing. I was thinking of getting the same battery but now I want to upgrade it entirely if I’m gonna spend the money. Found a 48v-12ah battery that’s 9.84 in long, 3.4in wide and 2.75inch tall. Will this fit into the seat? Also, do I need to change the controller to change the battery?

I was debating about doing the 48V upgrade, but decided I don't really need the extra speed and don't want to mess with a new controller and an LCD screen. Can I just swap out the 36V battery with a larger 36V 20Ah to get better range, or will it possibly fry some stuff? Also, looks like the brand of battery you're using is OKoman, still recommend them after almost a year?

Could u use the bigger battery on the stock internals?

Great video! What did you end up doing with the brake sensor wires? Is there a way to connect those? Or any advantage/disadvantage to keeping them unplugged?

So do I use a Anderson to xt60 to use the controller and my stock battery?

Can you help me out I’m trying to wire a key voltage switch on my rx can you tell me how to wire it up

Any thoughts on leaving the 36v volt battery as a back-up and installing a frame mount 48v battery? The controller auto detects what volt the system is running. My plan is running a 48v 18mah on the frame and leaving the 36v as a back-up on long trips. This way all I have to do is switch the plugs (I plan to re-wire outside the seat) when I want to switch over to the 36v. Any thoughts?

Thanks for making this video! It’s giving me a lot of confidence lol. Got a question if you might know the answer. I wanted to do pedal assist on my z1 but not planning on upgraded to a bigger battery yet. I would basically do the same thing you did in this video but with a 36v controller that supports pedal assist right?

Is the motor extension cord a 9pin? My z1 caught on fire and im doing a rebuild...the hubmotor cord is short

how do you get to the program screen? how do you stop it from being so jerky

Cool. When’s the next video?

What amp hours is your battery

Yo boss that T-plug to xt60 , the battery end is male and the xt60 from the controller is a male? Just for clarification. I need female adaptor from end to end to connect the two? Confusing enough lol? Thanks bro mabuhay from S.cali

Is this process the same with the rx because I want to upgrade the controller on it

With all the stuff that you bought, wouldnt it just be better off buying a S2 or zugo bike?
