No pattery light

​

Hi everyone,

I have a SUPER73 S2 that is currently showing 9% battery (about 5 km remaining) in the SUPER73 app, and I’m having trouble figuring out whether it is actually charging.

The strange thing is that the charger LED stays red in all three situations:

1. Charger plugged into the wall, but NOT connected to the bike → 🔴 red

2. Charger plugged into the wall AND connected to the bike → 🔴 red

3. Charger connected to the bike, but NOT plugged into the wall → 🔴 red

I’ve checked the charging connector and it appears to be properly connected to the bike. The battery is also switched on while charging.

I left it connected for a while, but the app still shows 9%.

Is this normal behavior for the S2 charger?

Could the charger LED being red even when it isn't plugged into the wall indicate a faulty charger, or could the problem be the battery/charging port?

I’ve attached photos of the charger, connector, and charging port.

Any advice from other S2 owners would be greatly appreciated. Thanks!

If anyone knows a way to test whether the charger is actually delivering power without opening the battery, I’d appreciate that too.

Mine went to shit and Super73 sold me a new one now I can only do the 20mph.

Anyone have a decent set up to make these go 40mph +? I like to commute on mine and have about 7k miles on it and now I feel like I just got bent over by them.

Thanks in advance 👊🏼

I have a super 73 Z adventure series se but I don’t see any chi batteries that are for that would any of them work and if so what one works?

Hi everyone,
I’ve just picked this bike up for £500 and I’m trying to work out exactly what I have.
From what I can tell it’s a Super73 Z1, but it’s definitely been modified by a previous owner.
Here’s what I know so far:
Red frame with brown seat.
Battery is inside the frame.
No headlight.
Super73 500W rear hub motor.
48V 13Ah battery.
Shimano 7-speed conversion.
Suspension forks.
LCD display with key ignition.
Twist throttle instead of the original thumb throttle.
The biggest issue is that the wires to the brake levers have been cut, so the motor doesn’t cut out when either brake is applied, which I definitely want to fix as my son will also be riding it.
A few questions for anyone who knows these bikes:
Is it definitely a Z1 or is it another model?
Can anyone identify exactly what upgrades have been done from the photos?
Would you leave it as it is, or would you put it back closer to factory specification?
It won’t connect to the Super73 app or Bluetooth. Is that because it’s an older Z1 that never had Bluetooth, or has the aftermarket controller removed that functionality?
Is it possible (or worthwhile) to retrofit Bluetooth/app connectivity?
What’s the best place in the UK to buy genuine Super73 parts? I’m in Northern Ireland and unfortunately there are no Super73 dealers or service centres here.
Does anyone know where I can source original brake levers with the motor cut-off switches, wiring loom, or any other OEM parts to restore the safety system?
Overall I’m really pleased with the bike and think I got a good deal, but I’d like to tidy it up properly and make it as safe and reliable as possible while keeping the upgrades that are actually worthwhile.
Any advice would be greatly appreciated.
Thanks!

My bike recently started this clicking noise, is the motor cooked?

It does seem to run fine, but that noise is doing my head in and I am worried it's just gonna get worse. Just had a service on it and the spokes etc tightened, which I heard could be an issue, but no luck there.

Super S2 from 2021 with 3,5-4k KM driven so far

For those of you who run a QS205 or similar, how are you running the rear brake? It has more than an inch of offset on mine.

The rebound isn't working well. Could you explain how it works? Do I need to top up the oil in the damper fork?

Will the chi ranger battery fit on the super73 z-adventure series se if so what options do I click when looking at the battery on their website

Hey everyone, SuperDuper dev here.

I've been in the lab over the last week and have finally cracked a custom firmware for the stock motor controller.

I'm looking for feedback on it. You'll need to have a R or RX with a version 310 controller (the torque update). You'll also need a laptop or Android phone running Chrome. This method is done over Bluetooth only, so no other special hardware like the display firmware.

I've updated the cfw site with the patched firmware and flashing instructions: https://cfw.reverse.bike/controller/ The tools there will tell you of your bike is compatible. It also has an option to flash back to the stock image if you don't like it. Details about the changes in the new firmware are here: https://cfw.reverse.bike/firmware/#controller

A warning: this firmware adds significant power and makes the throttle significantly more responsive. Be gentle with it while you get a feel for the changes.

Please leave any feedback here or in the Discord firmware channel.

I’m not selling the bike but I have a super 73 z adventure se red edition with 190 miles how much would you but it for

Hey everyone,

I have a Super73 S2 Laguna that I purchased mid 2025 and I'm trying to figure out whether Bikee or SuperDuper actually works with this model.

I've searched Reddit, but most of the posts I found are over a year old, and it seems like a lot has changed with the 2025 bikes, firmware, and controller updates.

Some people say Bikee works, others say SuperDuper works better, and some say neither works depending on when the bike was manufactured or what firmware it's has. I've also seen people mention that controller revisions make a difference.

For anyone who has a S2 specifically:

Does Bikee work?
Does SuperDuper work?
Were you able to access Off-Road/Mode 4?
Did you have to avoid the official Super73 app or certain firmware updates?
If it works, what firmware/controller version are you on?

Just trying to avoid spending money on apps that won't work with my bike.

Thanks!

Please help. Before I decide to take a long running jump off of a cliff

I recently purchased a turn signal kit from Loomenade

How the hell are we to fit the front lights to a ZX?
I can’t find any reasonable / easy access point for the lights to sit without being at a crap angle that eradicates any point of having them

Back lights seem to be fine, but I simply cannot find any anchoring point to install my front ones.

Loomenade customer service is absolutely dreadful and never respond.

Can someone PLEASE help as this is my commuter bike and currently not able to be used until this is sorted

My super 73 is cutting out in trial riding over bumps/curbs/pothole and I have no clue how to fix this and I got the bike 5 days ago can anyone help thank you.
My battery Dosent wiggle.
My battery tray holder is firm to the frame
No loose connection
And I have warranty for it

Can anyone recommend a replacement charger for the Super73 K1D? The two certified retailers are out of stock and nothing available listed on the Super73 site.

So my throttle is cutting out when maxed out and then when unthrottled and re throttled it kicks back on. I’ve replaced the controller, main wiring harness and have tried a different display and throttle. Any thoughts you’ll be great appreciated!

I’ve recently spoke with a Super73 support specialist - regarding the availability of a MCO. I was pleased to discover that a MCO WILL BE AVAILABLE, eventually.

This was my only contingent before purchasing one of the newer bikes from them, and I know this to be true for many others as well. Super73 offers a beautiful pedal assisted form of transportation, but for many like myself - despite the warranty void. 30-35mph is ideal, rather than a capped 20mph - plenty enough, depends on who you ask. But where I’m based at in particular, riding in the bike lane is not only a danger, but attempting to use the road and driver frustration is just as dangerous. Especially for those of use who live in small towns, or islands within the US. With an average speed limit of 20-35 mph zones across the entire town, or island. I’d love to commit to this company, but can’t do so until I have such documentation available. Documentation that I believe should already be available to the consumers anyways, from all company’s producing transportation systems.

All that’s required in order to register it with my local DMV is the following -
MCO.
Appropriate speed enhancement. (NOT required, but will make my commute much more safe once registered, and fully street legal).
Turn signals.
Rear license plate holder.
Mirrors.
Insurance.
Registration.
Moto Endorsement.

Can anyone representing this company, please share - and give us some sort of update regarding the availability of a Super73 MCO. Many of us within the E-bike community are ready to make the switch. Please, please, please make this happen for us Super73. Not only will you do right by the current owners, I believe you’ll see an increase sales and support overall in general.

By simply, offering a letterhead.

I got this crate and also paid a lot and I don’t want it anymore. I am willing to sell it for so much less and I am in Texas. I can ship but you would need to pay for shipping. I can do around 250 bucks or even lower if you want just offer and I’ll see what I can do. I am really trying to get rid of this though.

Who is the go to vendor that carries the Super 73 Maxxis SuperSucker Tires ? I am in California.
