When it comes to electric bikes, if the battery is the only problem and everything else, such as the drive system, smart display, and brake system, works, it's often worth repairing. If the whole bike needs attention, it's often not worth it.

One of the biggest shocks for new e-bike owners isn't buying the bike. It's discovering how much a replacement battery can cost a few years later. Before ordering a new battery for your Super73 RX, let's look at whether it's a worthwhile investment.

Years ago, I used to have this classic French car, and I remember taking it to a garage and them saying, “It would cost more to replace than to repair it”. It broke my heart. I loved that car, even though so much of it was rust. This is often the case for Super73 RX owners with battery problems.
Electric bike batteries are not cheap, and when it comes to replacing one on a Super73 RX, you really have to weigh the bike's value against the repair cost. In this article, we’re going to be doing just that.

How Much Is My Super73 RX Worth?
$10, I’m ready to pay and collect anytime. Just kidding. The Super73 RX is a premium electric commuter,gravel, e-MTB mixed-up bike. That good, many brands try to replicate it with cheaper versions. It’s incredibly difficult to give a set price because there are many variables for a bike like the RX. Hopefully, this table will help you with some indication of yours.
| Bike Condition | Typical Value (USD) | What It Looks Like |
|---|---|---|
| Excellent | $2,500–3,000+ | Low mileage, healthy battery, excellent cosmetic condition, includes the original charger, and has been regularly serviced. |
| Good | $1,800–2,200 | Average mileage, battery still holds a strong charge, a few cosmetic marks, everything functions correctly, and the bike has been serviced. |
| Fair | $1,200–1,800 | Higher mileage, noticeable battery degradation, worn tyres or brake components, and visible cosmetic wear. |
| Poor | $500–1,200 | Battery requires replacement or has significant faults, multiple worn components, or substantial cosmetic damage. |
As an e-Bike expert who has come across many pre-owned bikes, I find the battery the biggest factor. Everything else, such as a few scratches on the frame or needing service, is not high cost. The battery is a different story. That’s where you are looking at a very big chunk of money.
What Is The Cost Of A Replacement Battery?
Batteries for the Super73 RX do differ in cost, and it’s easy to get caught out thinking you can get them cheaply. When someone comes to me for advice on the Super73 RX that needs a new battery and wants to go through with it, here are the options I give them.
Buying A Genuine Battery
The genuine battery is the most expensive option, but it’s the best. You get top-quality, perfect fitment, and a lovely manufacturer's warranty. These batteries will give you years of great service without any problems. You’re paying between $1,000 and $1,300 for this.
Buying An Aftermarket Battery
You can also choose aftermarket e-Bike batteries. They are cheaper, but quality varies widely between brands. They don’t often connect very well with the controller, and if you get a warranty, it’s often very limited. You can also see more voltage sag, and the long-term life isn’t as good. You're paying between $400 and $900 depending on if you want budget or premium.
Battery Capacity
Not to confuse you further, but another big factor for both genuine and aftermarket batteries is capacity. The bigger the capacity, the more cells, the higher the cost. The 400Wh to 600Wh batteries are much cheaper than 700Wh to 1000Wh batteries.

Can My Super73 Battery Be Repaired?
It’s important to consider whether your battery can be repaired. If it has dead cells, the answer is pretty much no, but you might have a simple fix such as;
- Charging port replacement
- Connector repair
- Battery Management System (BMS) replacement
- Cell balancing required
An expert can tell you this, and it could be a huge long-term saving for you. Most bike shops and manufacturers offer replacements, but some experts will perform these repairs at a much lower cost than a new battery. Never ever try to open a battery up yourself. It’s so dangerous.
Repair Or Replace?
This is the tough bit: working out whether it’s time to replace the bike or repair it. The situation is different for each person. The questions you need to ask yourself are. First, what is the condition of the bike you have, and second, is the repair worth it?
Sentimental Value
I used to be a very sentimental cyclist, and because of this, I once had a huge bike collection before it just became too much. For me, some of my bikes have a huge amount of sentimental value, and I have put way more money into them than they’re worth because they've taken me on some amazing adventures and hold some of my best memories. It’s worth considering this.
Private Sale vs. Trade-In With Upway
If you plan to get rid of the bike, there are two options. The first is a private sale where you sell it yourself. You are not going to get a huge amount of money, and it’s always important to be completely transparent about the condition. If the battery is completely dead, selling it as a spare or for repairs is the best option.
You could trade in with Upway. Upway is a pre-owned e-Bike specialist that refurbishes e-Bikes following mechanical and electrical inspections. They are then repaired and sold on with a warranty and excellent customer support. If the battery is still working but not very effective, they will often take it. Here’s why so many people go through Upway trade-in.
- Quick process.
- No advertising.
- No dealing with buyers.
- Professional inspection.

Frequently Asked Questions
Is a Super73 RX worth repairing in 2026?
Can I replace a Super73 RX battery myself?
For any e-Bike, if the battery is removable and you're using a direct replacement, it's pretty simple. Anything internal or requiring coding should be reviewed by a professional.
Does a new battery increase the resale value of a Super73 RX?
Of course. As someone who is always looking at e-Bikes, I'm willing to spend a lot more if I see one with a new battery. Not only does it mean it will last a lot longer, but it also shows the user cared enough to spend that money on it.
Key Takeaways
- The battery has the biggest impact on value: A good battery really improves the value of an e-Bike. A bad battery hugely removes value.
- Compare costs before spending money: If the battery is more than what the bike is worth overall, it's not worth replacing. Unless it has significant sentimental value, it's better to walk away.
- Think about your long-term plans: If you absolutely love the Super73 RX and don't want any other bike, you might want to consider another battery, even if it's not a great financial option. If you have the bike, it's right for you, and if you are going to have it a long time, it might just be worth it.
