Introduction

Restock in 7days - stock sells out quick.

The TC1000 controller is compatible with the following models:

• SurRon Ultra Bee
• Torp Motor TM25
• SurRon Ultra Bee

Note: The TC1000 controller is not compatible with the Segway X160 or motor model number P/N: 11100-YQ2A-0100. Please verify your motor model number before installing the TC1000 controller. Generally, all SurRon/Segway X260 motors manufactured after 2018 are compatible with the TC1000 controller.

Compatibility and Features

The TC1000 controller works seamlessly with both versions of the stock display (L1 E & the off-road version), displaying both speed and distance. For additional options such as battery monitoring and settings, you will need to use your smartphone or purchase a Torp Display, sold separately.

Easy Installation

This plug-and-play controller requires no prior knowledge of electronics or programming for installation. All necessary components for successful installation are included in the box. Despite the ease of installation, it is strongly recommended to enlist the services of a qualified professional to ensure all components are connected correctly and functioning as intended. Improper installation may void the warranty and cause damage to the product.

Important Information

Torp controllers and engines are non-stock parts for SurRon, Talaria, and Segway motorcycles. Installing these non-stock parts transforms the motorcycle from stock to non-stock, which may render it non-compliant with road safety regulations and potentially illegal for street use. It is your responsibility to be aware of and adhere to all relevant local laws and regulations. Modifications may also affect insurance coverage and warranties.

What's in the Box?

• TC1000 controller
• Wiring harness
• 5 phase screws with washers
• 2 hex keys and 12 bolts
• 4 stickers
• Heat sink
• Short instructions

Note: Use only the tools and screws that came with the controller. Using tools and screws not included in the parcel, not following these instructions, or not using the circuit breaker can cause serious damage to you and your bike, and voids your 2-year warranty.

Mobile App for IOS and Android

All settings and diagnostics are managed through an intuitive, easy-to-use smartphone app available for both Android and IOS. Users can use their smartphones as a display during rides and to configure all the controller's features through the app.

DISCLAIMER:

EVFREAKS LIMITED does not accept liability for any DIY battery bypasses or installations on our supplied controller upgrades. We recommend having the controller installed by a professional at our workshop, even though fitting instructions are provided.

Upgrade your Sur Ron and get more power with EVFREAKS high-discharge power kits - 72V Batteries, ASI, TORP Controllers STAGE3 if paired with an upgraded motor like TORP, SOTION, or EBMX. Our 72V batteries will max out your stock Sur-Ron motor to its fullest 18.5kW and will max out any other aftermarket motor from 25kW up to 40kW, depending on which option you choose and if you have a powerful enough controller to handle it. These are Premium EVFREAKS Ultimate Performance Batteries - our motto is quality over quantity.

Features:

• ⚡️ AWG6 Phase Cables & Bigger Breaker Replacement on the bike side.

  🔌 QS8 AntiSpark Connectors

  📱 BMS Mobile App (Android & iOS)

  🌡 Temperature & discharge protection

  🔩 Stainless Steel Case (1.5mm)

  🔬 Grade A++ Cells (Samsung/Molicel)

 Extras Included

• 120A breaker replacement
• Upgraded AWG6 silicone phase cables with QS8 connectors
• Air wedge (to secure battery from wobbling)

What Sets EVFREAKS Batteries Apart?

We manufacture at a small scale in Germany in-house, ensuring cell quality verified to A++. Our 72V batteries use only premium cells: Samsung, Molicell - grade A++. High-quality cells offer bigger capacity, better resistance, and less voltage sag, resulting in more range and consistent power delivery, with less heat and more power overall. Our battery casings are made from stainless steel, laser cut from 1.5mm stainless steel, and laser welded to ensure durability and safety. Our motto is quality over quantity, which is why we don’t import ready-made batteries or resell them.

Range Expectations:

Range depends on factors such as rider weight, terrain, riding style, gearing, wheel size, and sprocket size. Our team rides on EVFREAKS race Sur-Ron weighing 70kg, with a 72V 55Ah dominator battery, BAC8000 controller, and TORP TM25 motor running 25kW or 33.3HP. With a rider weight of 85kg, plus gear, spare tools, water, and full armor adding another 15kg, the total weight is 100kg. This setup does approximately 50mile range in hard off-road riding, including steep inclines, wheelies, and wheel spins, running 25kW peak and 600 phase amps. This feels like a stark Varg, though it could run more phase amps up to 800, but that would generate more heat.

45AH vs. 55AH: The Capacity Dilemma:

The debate between 45Ah and 55Ah batteries is significant. Realistically, 45Ah offers 50% more capacity than stock, while 55Ah offers 70-80% more range. With the 60V 65Ah battery, you get up to 100% more range, but its discharge is limited to 12kW peak since it is not a high-discharge battery. Still, it is a substantial upgrade considering your stock Sur-Ron runs 4.8kW - 6kW peak.

Safety Assurance:

BT BMS (Battery Management System) meticulously monitors all vital parameters, such as group cells, and self-balances as needed. It reads the temperature of the cells and BMS and switches off if parameters are exceeded. This ensures cell longevity and safety, regulating current to prevent damage under extreme loads.

PLEASE NOTE: EVFREAKS BATTERIES ARE STRICTLY FOR RACE USE!
BATTERIES SHOULD NEVER BE STORED INDOORS!
BATTERIES MUST ALWAYS BE ATTENDED WHILE CHARGING!

EVFREAKS LIMITED does not accept liability for any DIY battery bypasses or installations on our supplied ASI, TORP, NUCULLAR controllers upgrades for SurRon, Talaria, Ultra Bee, or any other e-bike. We recommend having it installed at our workshop in Manchester by professionals, even if we supply fitting instructions.

Why Upgrade to EVFreaks Custom Loom?

The stock Sur Ron wiring loom (L1E & Off-Road) is known for long-term reliability issues, especially in wet and muddy conditions. Common failures include throttle malfunctions, power cuts, and connectivity issues, often caused by the OEM loom.

If you're upgrading your Sur Ron with new brakes, removing sensors, or swapping controllers, displays, motors, or batteries, the stock loom quickly becomes cluttered and inefficient due to limited space in the frame.

Better fit & easier installation

The Sur Ron frame has tight cable management space, often leading to jammed wiring. Our custom loom frees up space, making installation smoother and hassle-free.

More space for components

 Replacing the OEM loom opens up extra room, allowing you to relocate your DC-DC converter higher under the key compartment. This keeps it away from water exposure, preventing long-term failures caused by its original low, exposed placement.

Proven performance

 We’ve used these custom wiring looms in our race and custom builds since 2021, and now, we’re making them available to you.

How to order:

Specify your controller, battery, motor, and road/off-road setup in the order notes.
Usage type – Road-legal or off-road?
Lighting preferences – Need front/rear lights, indicators, or a horn?
Send photos for accuracy: [info@evfreaks.uk](mailto:info@evfreaks.uk)

Once you place your order, we’ll confirm details before production to ensure a perfect match for your build.
