E Ride Pro SS With EBMX 9000 Controller: A Dramatic Performance Upgrade

Introduction

The E Ride Pro SS is an impressive electric bike straight out of the box. Its stock controller delivers around 12 kW of peak power, which is already plenty for a machine in this class. But the EBMX 9000 controller changes the character of the bike entirely. With roughly 50% more power and double the torque, the upgrade transforms an already quick e-bike into something that demands respect.

This review covers the stock performance baseline, the installation process, and how the bike behaves after the swap. It also walks through the companion app, which offers deep customization for riders who want to fine-tune the experience.

Stock Performance Baseline

Before swapping in the new controller, the E Ride Pro SS was tested with its stock setup. At around 80% battery, the bike hit a top speed of roughly 56 mph. The 0 to 30 mph run came in at 2.29 seconds, and the 1/8 mile was covered in about 10 seconds. For a stock e-bike in this class, those numbers are genuinely quick.

The stock controller peaks at about 12 kW, which is more than enough for most riders. The bike feels responsive and lively, with strong acceleration that can catch you off guard if you are not ready for it. Even so, the stock setup leaves some headroom, and that is exactly where the EBMX 9000 steps in.

Installation Journey

Installing the EBMX 9000 controller is not a simple plug-and-play job. The process requires some mechanical knowledge and patience, especially if your bike is an earlier version. In this case, the kit shipped with a harness for the 2.0 version of the E Ride Pro SS, but the bike in question was actually the 1.0. That mismatch meant a different harness was needed before the install could proceed.

Thankfully, a local shop had the correct 1.0 harness in stock and shipped it out within a couple of days. Once the right parts arrived, the installation was completed with the help of someone experienced with e-bike controller swaps. The process involves connecting the new controller, securing it in the frame, and running a calibration so the system knows the motor type, battery series, and throttle position.

A few other things were addressed before the install. The bike received a fresh battery, new tires, new rotors, and a new headlight. Installing a new controller onto a bike with a weak battery is not recommended, so making sure the battery was in good shape was an important first step.

Dyno Results Before and After

Before the swap, the E Ride Pro SS was run on a dynamometer at 63% battery and produced around 7 kW of power to the wheel. After the EBMX 9000 controller was installed, the same bike put out 10 kW to the wheel even at a slightly lower 60% battery. That is a significant jump in usable power.

The graph from the dyno run shows roughly 50% more power and double the torque compared to the stock controller. Those numbers translate directly to real-world performance. The bike feels like a completely different machine, with acceleration that is hard to keep under control.

On-Road Performance After the Upgrade

Once the new controller was in, the difference was immediately obvious. In race mode three, the bike is brutally fast. The front wheel lifts easily under hard throttle, and keeping it down takes real effort. The acceleration is so aggressive that it feels like riding a pissed off bull.

The 0 to 30 mph time dropped to 2 seconds in race mode three. In race mode two, the same run came in at 2.42 seconds. A lot of that variation comes down to how well you can manage the front wheel, because the torque makes wheelies almost effortless.

One thing that becomes apparent with all this extra power is that the stock tires are now a limiting factor. The skinny tires break traction easily, and once they let go, there is no recovering. A wider, thicker rear tire would help put the added power down more effectively. Upgrading the tires and rims is a natural next step for anyone running this controller.

Off-Road Performance

The EBMX 9000 controller also shines off-road. On a technical trail that had been cleaned up recently, the bike felt much easier to ride aggressively. Climbing a steep, loose hill that was previously a challenge became noticeably faster. The rear wheel spins and spits dirt, but the added power makes short work of steep sections.

The bike also has a reverse mode, which is a genuinely useful feature. It is one of those things you do not realize you need until you have it, similar to heated seats in a car. Once you have used it, going back to a bike without it feels like a downgrade.

App Customization and Setup

The EBMX 9000 controller pairs with a companion app that offers deep customization. The app connects to the controller instantly, with no Bluetooth pairing issues. That reliability is a welcome change, because wireless connections on e-bikes often fail or drop out.

Inside the app, you can adjust nearly every parameter the controller supports. The first step is to go into the general settings and select your bike type, motor, and battery series. After saving those details, the controller runs a calibration. If you change wheels, tires, or gearing, you should update the app and rerun the calibration so the system compensates for the new components.

The throttle settings are where the fun begins. Ramping time controls how quickly the power comes on. A lower value means more immediate response, while a higher value smooths out the delivery. Negative time ramping adds a slight delay when you roll off the throttle, which can feel more natural for riders coming from motorcycles. Input deadband filters out small throttle movements, which is useful when riding over rough terrain where your hand bounces around. Throttle expo mode adjusts the torque curve, and the recommended setting is natural polynomial.

The app also includes race and street modes. Race mode offers three levels of aggression, with race three being the most intense. Street mode limits the bike to about 25 mph and reduces the torque to a much tamer level. That is useful for lending the bike to a less experienced rider or for extending range when you do not need full power.

Buying Advice

The EBMX 9000 controller is priced at around $1,000. For that money, you get roughly 50% more power and double the torque compared to the stock controller. A few years ago, getting this kind of performance from an e-bike would have required spending an extra $5,000 to $6,000 on motor and battery upgrades. The controller alone achieves a similar result for a fraction of that cost.

That said, the installation is not trivial. If you do not have experience working on e-bikes, you will likely need help from someone who does. The harness compatibility issue is also worth noting. Make sure you have the correct harness for your specific version of the bike before you start.

The stock tires become a weak point once the extra power is unlocked. Budget for a wider rear tire and possibly new rims if you plan to ride aggressively. The added traction makes a meaningful difference in how the bike handles the increased torque.

Conclusion

The EBMX 9000 controller is a dramatic upgrade for the E Ride Pro SS. It takes an already quick bike and makes it significantly faster, with acceleration that is genuinely hard to manage at first. The companion app adds a layer of customization that lets you tailor the power delivery to your riding style and skill level.

The installation process is the main hurdle, and the harness compatibility issue is something to check before you commit. But for riders who want more performance from their E Ride Pro SS, this controller delivers in a big way. It is an awesome piece of equipment that completely changes the character of the bike.
