Preparing an E-Twow GT: Maintaining lightness while boosting performance
Performance isn't just for heavy-duty machines. The E-Twow GT is a compact, lightweight, and agile scooter, built on a robust frame. Prepared by the workshop, François's scooter – he's an engineer at Rage Mechanics – maintains its 13 kg weight and reaches 50 km/h on private property. The key to this modification lies in two components: a high-discharge battery and a controller capable of utilizing its power. The rest involves ensuring the scooter is safe at that speed.
The essentials
- Our customized E-Twow GT: 13 kg, 3200W at 52V, with a top speed of 50 km/h on private property.
- The Performance 52V 9Ah battery, using Molicel P45B cells, is only compatible with a replacement controller.
- To keep your original GT in top condition, our replacement 48V 15Ah batteries are available for each version.
- The braking system and front tire are being updated simultaneously with the power system.
The philosophy: a preparation tailored to the machine
Preparing an E-Twow GT doesn't mean turning it into a 40 kg scooter. The main advantage of this machine is its lightness: it's easy to carry, store, and handle. The preparation aims for performance without adding unnecessary weight. This is what guided the modifications made to the machine presented on our page E-Twow GT prepared by Rage Mechanics.
Here's what has been changed:
According to the specifications of this setup:
| Element | Rage Mechanics Preparation |
|---|---|
| Base | E-Twow GT |
| Battery | 52V, 9Ah, using Molicel P45B cells |
| Power | 3200W at 52V |
| Braking | Drum brake |
| Front tire | Inflatable |
| Screen | SmartDisplay with directional throttle |
| Speed | 50 km/h on private property |
| Weight | 13 kg |
The battery: the heart of the preparation
Our 52V 9Ah Performance battery for E-Twow GT uses Molicel P45B cells, known for their high discharge rate, in the format of the GT's deck. Its capacity is lower than that of a range battery, but it can deliver much more current. It is this current that provides the acceleration.
Its specifications are clear on one point: it can only be installed with a replacement controller. The original controller is not compatible: the battery and controller must be changed together, never one without the other. Our guide on upgrading to a higher voltage explains why each component in the system must be replaced.
Like all of our batteries, this one is assembled in our workshop in France, using high-quality cells and a BMS (Battery Management System) that manages charging, discharging, balancing, and thermal protection. The charger must be compatible with the new voltage.
The controller
The controller is the component that regulates the current sent to the motor. With the Performance battery, it must be replaced with a compact model capable of handling the voltage and current, and adjustable to be adapted to the motor and battery. Our guide on electric scooter controllers explains its role. We do not currently sell controllers, but we offer complete installation services: selection, wiring, and configuration, with our installation package.
Brakes and tires: monitor speed
An original GT model is designed for a lower speed. With increased power, two key aspects need to be reconsidered:
- Braking: Our preparation uses a drum brake, which must be carefully checked and adjusted
- The front tire: An inflatable tire provides grip and cushioning, which is important for both braking and cornering.
The small wheels of a compact scooter are very sensitive to road imperfections. When traveling at 50 km/h, especially on private property, the surface should be known and clear of obstacles.
Maintaining the original performance of a GT
Not everyone is looking for performance. For a GT used daily, what's often most useful is a new battery that restores the lost range. We offer replacement 48V 15Ah batteries for the 2020 GT, GT SE, GT SL, and GTS models, using branded 21700 cells, assembled in France. You can find them in our batteries for E-Twow. Please choose the correct version for your machine, as the connectors differ depending on the model.
Workshop tip
On a small machine, every gram and every centimeter matters. Before ordering the Performance battery, let's discuss with you the controller you intend to use and its placement within the deck: often, it's the integration, rather than the power, that determines the success of a compact build.
And what about the law?
On public roads, an electric scooter is limited to 25 km/h. The GT, tuned to 50 km/h, is used on private property. See our guide on laws and unlocking.
Frequently Asked Questions
Can I install the Performance battery with the original controller?
No. The battery's specifications indicate that it can only be used with a replacement controller. The original controller is not compatible with it.
Does the preparation process add weight to the GT?
Very little: our modified machine weighs only 13 kg. The Performance battery fits within the dimensions of the original deck.
Does the battery performance affect the range?
Its 9 Ah capacity is lower than our replacement batteries, which offer 15 Ah. It prioritizes the available current; battery life then depends heavily on riding style.
What battery should I use for my original GT?
A replacement 48V 15Ah battery that perfectly matches your model: GT 2020, GT SE and SL, or GTS. If you are unsure, please send us a photo of the original battery label.
