Smart Regional Power Control
Unlock smarter performance with techtron’s 5-Level Intelligent Assist System—designed for legal compliance and rider freedom across the globe. From pure pedal mode to full throttle, each level is controlled via the app, adapting to local laws and your riding style.
Level 1 – Pure Pedal Mode:
Traditional cycling with zero motor support. Quiet, efficient, and battery-saving.
Level 2–3 – Eco & Commute Assist:
Smooth, responsive power calibrated for everyday riding. Fully compliant with UK and EU e-bike laws (25 km/h limit).
Level 4 – Performance Boost (App-Unlocked):
Unlock faster assist with enhanced torque and speed—available only in permitted regions via the techtron app.
Level 5 – Full Throttle Mode (App-Unlocked):
Ride without pedalling using throttle-only mode. App-unlocked in throttle-friendly zones such as the USA, LATAM, and parts of Asia.
Smart Compliance via App:
All enhanced modes are managed via the techtron SmartApp, featuring geo-fenced region control, user verification, and dynamic firmware updates.
Built for Global Riders:
Whether commuting through London or cruising in California, the system adapts to your region—giving you performance where allowed, and peace of mind everywhere else.
Stronger, Lighter, Smarter
Crafted from advanced AM60 magnesium alloy, the TEF EVO weighs as little as 14.5kg—making it one of the lightest e-bikes in its class. Lighter than aluminium yet impressively strong, it delivers smooth, stable performance with exceptional ride comfort and a premium, agile feel.
Ride Safer. Brake Smarter.
The techtron TEF EVO series features the Tektro HD‑E3520 hydraulic disc brake with an integrated motor cut-off sensor for instant power disengagement. Enjoy smooth, controlled stopping with 2-piston calipers, reach-adjustable levers, and a low-maintenance mineral oil system—built for precision, safety, and total ride confidence.
> Expand to Find Out More
The techtron TEF EVO series is built for riders who demand more from their braking system. That’s why we’ve equipped every model with the Tektro HD‑E3520 hydraulic disc brake — delivering powerful, responsive braking and next-level safety integration.
At the core is a built-in motor cut-off sensor that instantly disables power the moment you brake. No lag. No hesitation. Just complete control, exactly when you need it most.
Why It Sets a New Standard:
- Motor cut-off built into the brake lever for real-time power disengage
- Helps prevent overrun in emergency stops and high-speed braking
- 2-piston hydraulic calipers = smooth, consistent stopping force
- Reach-adjustable levers for a tailored grip and comfort
- Advanced mineral oil system = reliable performance, less maintenance
Ride Safer. Brake Smarter
With Tektro HD‑E3520, every squeeze of the brake means more than stopping, it means protecting the rider, conserving control, and building trust in every ride.
Silent. Smart. Strong.
Powered by the ToSeven C7‑XR rear hub motor, delivering torque-sensing precision, real-time adaptive power, and whisper-quiet performance. Compact, lightweight, and fully integrated with smart app control, it’s built for seamless acceleration, smooth cruising, and total ride confidence.

High-Tech. High-Performance. Fully Integrated
The ToSeven C7‑XR rear hub motor powers the TEF2 & TEF3 with seamless control, torque-sensing intelligence, and whisper-quiet performance. Paired with a Shimano 7-speed drivetrain, Tektro hydraulic brakes, and smart app connectivity, it delivers a smooth, adaptive ride—perfect for modern commuters and urban explorers.
At the core is the C7‑XR: a lightweight, high-efficiency motor that brings mid-drive responsiveness without the weight or complexity. With built-in protection systems, a sealed aluminium housing, and IP67 waterproofing, it’s ready for all conditions—today and tomorrow.
Why it Stands Out:
-
Rear-Hub Torque Sensor – Mid-drive feel with hub simplicity
-
Torque + Cadence Sensors – Adaptive real-time power delivery
-
Firmware-Ready – Custom torque maps, speed tuning, regenerative braking (2026)
-
High-Speed Gear Ratio – Smooth cruising up to 32 km/h (region dependent)
-
Smart Protection System – Thermal and overcurrent safeguards
-
Noise-Dampening Shell – Sealed aluminium for quiet, low-vibration rides
-
Lightweight & Compact – Just 3.5 kg with 135 mm dropout
-
IP67 Waterproofing – All-weather, all-season durability
Built for intelligent riding.
The ToSeven C7‑XR brings next-generation performance to the TEF2 & TEF3—ideal for folding, urban, and app-connected e-bikes.
Ride smarter. Ride smoother. Go further.
