I broke the stock controller while messing with the STM32 SOC. So now I'm replacing it with a generic controller that has more options. Really wanted to get this bike back on the road.

This cat is a GENIUS...Love it man! 2 Thumbs up.....That was a lot of hard work.
Great video! Very informative and still terrified to cut and solder my wires lol! I need to keep watching this for confidence!
Nice! This was very informative. Thanks for making this video! :)
Can't wait for the next video :-) Just ordered mine, got loads of mods in mind can wait to get started. a screen is deffo on my list but the electics scare the shiz outta me.
Bro you smart af 🤯 it’s crazy
Liked this Video even if i dont even have a bike!
it's actually not useless to add that capacity for one reason, it's much quicker with more charge! I ride a z around san francisco and while my bike can easily make a trip from one side of the hilly city to the next, it can get a little slow on hills by the end of it, so I charge it at work just to keep it peppy. I would love more capacity for that reason alone.
Great video, most of it is above my head. My battery or more likely the controller is bad, need more info than this video provided to swap out. I do not think I have the skills to perform this type of repair anyways but don't know what to do. Super73 said order an entire seat assembly but that they are sold out
Dude... Luna has the BBSHD and for a few duckies more, you can get the ludicrous mode, it is a Bafang 1500 mid drive with 52 volt and 50 amps continuous and 80 amp peak, a shift sensor and a 21 amp hour package will give your machine a 50+ MPH and become a hill climbing machine. It has a cassette in the rear, giving you great speed and torque options for the mid drive and components I believe it is about 700 and the ludicrous mod will cost you an extra 250 dollars and bump you up too 2500 watts. You can enjoy over 300nm of torque... the g force is addicting!
This is Genius! Do you know what kind of connector is that 14v rail with yellow wire? and if i can connect a Baja Designs S2 pro with it? Thanks a lot!!
you connected a 48v controller to the 36v battery? works perfectly fine? whats the top speed and the amount of time it runs now? is there more videos of this and showing detailed information id love to try this
Had a ? I’m upgrading mode to the 48v battery and controller but I still wanna use the stock battery as well not at the same time but like Mybe it be a setting in the program with like a switch to go from one battery to the other u think that’s possible
At 15:09, you mention a bluetooth module. Did that come with the controller? Can it be purchased separately?
Thanks for the info! Just bought a z1 and was wondering since they are all using the same hub motor. Can the z1 take the 48v battery the other models are using or is it a different controller?
Bet it motor can handle 48v with a different controller.
Hi, thanks for sharing your experience and knowledge. Do you have any comments regarding the fenders? do they work properly? I ask because I have read that they are not worth the money and other options work better.
I’m loving the oem fenders. Fit perfectly and work a treat. I wasn’t aware there are alternatives.
what Controller can replace the Super 73RX Controller?. Im looking at the Grinn Tech Phaserunner L2. woukd this work? I Need to add torque ,
Any update on the "extra" higo" connector? I've sourced an LCD controller display that's commonly paired with the same model number controller in the z1, so I'm hoping it's possible to connect it to the extra 5 pin higo connector.
Yeah, it was RS-232 (rx & tx). No idea what's on the line since I damaged mine before being able to sniff it.
@@JuliansRandomProject thanks
Did you just replace the controller or did you have to change the battery as well? Also could you link where you got the controller please?
What's the name of the lcd display that you have? And where to buy it at?
Im new to e bikes and want to get a Mario ebike shipped to Australia. Can you explain what a Grin phase runner can do for the bike. Its a 1000watt 52V. Can the phase runner be programmed to boost output/go faster?
Looks like the "phaserunner" is a motor controller and it's very configurable so I'd say "yes, it can be programmed to go "faster". Pair it with a good motor and throttle, bolt that stuff to your bike (or buy a bike already equipped) and you'll be right as rain.
Hey Erik its Johnny here I iam Australian sales for Mario contact us if you need to happy to help you with anything you need
I want one but the battery life worries me. I'm 230 lbs and from embarcadero Bart station up over the hills and to the other side of SF like around ocean beach I don't think it'll have enough to get back over SF to get home. So I was gonna go with the city scrambler cause it has a 19.2 amp hour battery instead but I like the super 73 looks and simplicity more
I'm about the same weight and this bike doesn't work well with the weight. I Added gears which was really helpful but 2 weeks later my battery died, or maybe the controller but super73 is very unhelpful releasing any info regarding a fix, they just want to sell you a knew one. Here's the catch, all sold out.
Nicee video i wil sugest to upgrade your battery to a 48v
Hey, got a replacement battery from Super 73 folks and used it a few times, now can't charge it, could I send it to you to diagnose?
Thank you for uploading videos like this!
What is the easiest way to change my batteries after the life cycle ends, I just find out the company doesn't sell the replacement seat/battery for this bike.
Please make a video.
You are awesome!
I will be waiting for that video! LoL
Thanks for acknowledging
Excuse me how does one know when a battery is dead you see my bike stopped working when I turn it on it only shows red light and It doesn’t let me charge it, I think it’s a wire 2nd from the throttle I don’t know I need a electricians help haha
that cable might be so you can add a light
I like the video cause I own a Z1...but you didn’t really show how to DYI...how you connected the new controller.
/Bklyn👑
That extra probe is for peddle assist
As the Z1 doesn’t have peddle assist so it wasn’t connected !!
Did you find this out for certain or just speculating? Also, are you talking about the two wire RX TX (green and yellow) or the black 5 pin higo connector?
I have a Z1 I was riding down hill one day and I loud clunking sound came from the back wheel then whole bike shut down the button on the side of the bike never shut off but the lights on the throttle went out and the bike wouldn’t move I had super73 mail out a new throttle and that wasn’t the issue do you have any ideas ?
Aakyia Goodwin I’ve had the same thing happen as well as to others I’ve called to on reddit. Seems like someone was able to get a new controller from super 73. I emailed them a week ago and didn’t get a response
Hello. Someone know if this throttle works on ZG ? I have an EU model, so need pedal assist. and I want to remove pedal assist, so someone know how to do, or if this throttle this works ? Have a good day
I've had my bike for 1 month, approx 25miles, the battery button remained actived over night. I charged the battery for 12 hrs, the battery button lights up and only the red light [on indicator near throttle] comes on. The motor does not activate. Any troubleshooting tips?
Try charging longer and every 10 minutes unplug/turn off button and then plug/turn on again. If that doesn't work you may have dropped below what the BMS is willing to charge up from. In this case, open up the pack and manually charge the pack for 10 minutes and normal charging should be able to resume via the provided port. Openign the seat and blue battery pack should be a last resort. Godspeed. p.s. If you're in the bay area, hit me up on Instagram, could make for a good video, reviving your bike.
Ey bro I’m planning to swap my battery to 36v 35ah. How can i connect it to the original charging port of the stock battery?
If you're going to swap and not add, you'd just solder the thinner wires from the charging plug to the new battery or new battery BMS. Good luck! Let us know how it goes, maybe post a video
JuliansRandomProject what if I’m just gonna add a battery? Will the stock charger work? Yepp I’ll probably make a vid
@@wreckitralph2037 for 36v, the charger that came with your bike will work. the charging 'port' (female barrel plug) goes to the BMS stock. You'll want to connect that to the new battery somehow. If you are using the same chemistry you might get away with wiring the stock with your new one in parallel.
JuliansRandomProject awesome. Thanks bro
Could you not put a new chip on the existing controller? (Although new one has some nice features)
Could easily solder on a new STM32 but it would lack the firmware flashed at the ebike factory. Ideally one would dump the firmware, or get a copy of generic fw and then flash it back if needed. I failed to successfully dump it so went down this route as a result. One risk with using fw not intended for my controller, even if the SOC part is identical is that one manufacture may use an output to drive a break light and the other uses the same signal to drive a motor. Controllers are cheap, best to just swap at this point.
Never see these bikes last long. Just going uphill is a struggle after a bit of time. For the price of the bikes plus modification and maintaining, might as well buy an old small 100-125cc motorcycle and turn it into a cool cafe racer.
Which controller did you use, I keep running into endless deadends trying to find it. Cheers!

@@JuliansRandomProject - You're a saint!
By the by, the white SD wire can be snipped for a nice little boost in top speed. 29.2mph is my record thus far on an otherwise stock Z1 that's 2 days old.
@@bandwagon240 are you saying a white wire in the stock speed controller on the z1 can be snipped? I've been trying to figure out a way to get rid of the 20mph speed limiter. Thanks.
@@Joekpshaw Yep, the SD wire.
@@bandwagon240 nice, is that the only white wire in the speed controller? Or can I get to it without taking the potting apart? I didn't see it mentioned in this vid and haven't taken my bike apart yet.
Coming across this- please help me get my Z1 back on the road- My throttle light won't turn on so it wont run, and I've contacted Super 73 and they say I need a seat assembly but they don't think they will ever be available.
Your best bet will be to buy a new motor controller (I think this one was about 500W) like the one in this video and move over the connectors for the motor and throttle. Good luck!
Yeah cost reduction, no name battery, no name motors, no name controller, cheap tires( everybody else offering at least kenda's) no derailleur, no shifter, knowingly selling people $3,500 ebikea knowing that they have all kinds of manufactur defects.. and Limited padding in the seat. When it comes to cost reduction 73 is definitely class-leading.
Can you send me diagram on motor wires
Are you self taught or did you go to school for electrical engineering?
Autodidact.
Uhhhh... I bit off more than I can chew
Are you an electrical engineer? You seem to know a lot about this...
Nope. I just play with the stuff and like to learn.
@@JuliansRandomProject Great job! You are a man of great wisdom.
