    Internal Wiring
    By threading all of our cables through the headtube and downtube of the bike frame, Thunder 1 looks just like a regular bike. The goal was to let a rider enjoy all the perks of an e-bike without needing to tell the world that.

    Integrated Battery
    One of our main challenges with the Thunder series was balancing battery capacity with a lightweight and slim frame. We created a custom frame to house our newest, most compact battery design yet which has a high energy density.

    Built-in Electronic Sensors
    Our whole drive system, including the VCU, controller, torque sensor and control panel are all integrated into the frame. R&D focused on developing the lightest and smallest electronic components without sacrificing performance.
Velopower E35
We developed an entirely new drive system for the Thunder series. Using smaller and lighter components, we’ve developed one of the smallest and quietest hub motors out there in the market, powered by a torque PAS sensor to deliver the smoothest ride possible. E35 powers Thunder 1 ST, which enjoys all the benefits of our new drive system and will go up to 52 miles with our 36V 352.8Wh Battery.
Control panel
A simple and discrete module installed on the toptube of the frame. Easily power on or off your bike with your thumb, with a LED ring and light indicators to provide information on your bike’s current battery and PAS level.
Apple Find My™
Thunder 1 ST is our first e-bike that is compatible with Apple Find My (iOS only). Rest easy knowing that you’ll always be able to keep an eye on your bike right on your phone.
  • Hydroformed Aluminum
    To ensure a frame which is stronger, lighter and more aesthetically pleasing, we used hydroformed aluminum to create a custom shape for our Thunder series.
  • 3D Liquid Forging Technology (LFT)
    Using 3D Liquid Forging Technology (LFT) we’ve created a custom frame structure which is stiffer, stronger and allows us to insert our entire drive system into the bike for the sleek integrated look while simultaneously increasing the tire and fender clearance.
  • Forged Dropouts
    We used forged dropouts for the mounting points of the fender and the frame to ensure a stronger support and best fit for our hub motor axle nut.
Quality Components
Reliable and performance-driven configuration
  • TEKTRO Hydraulic Disc Brakes
    The Thunder series e-bikes are equipped with Tektro hydraulic disc brakes to offer the absolute strongest stopping power in all weather, including wet and muddy conditions.
  • PROWHEEL Narrow-wide Chainring
    The Thunder series e-bikes use PROWHEEL’s narrow-wide chainring to ensure better chain retention, reducing the chances of chain drops and improving overall drivetrain efficiency and stability while cycling.
  • Selle Royal SRX Saddle
    Thunder 1 ST is equipped with a custom Selle Royal SRX saddle which is slightly wider and equipped with a shock ball under the cushion, making it more suitable for people with different sit bone widths and is more comfortable to ride, especially for more casual riders.

    The wave-shaped design provides excellent support for the lower back and sit bones, especially during long-distance rides. The additional matrix-style padding makes the saddle more comfortable on rough terrain. The ergonomic pressure-relief groove design reduces pressure on the sit bones.
  • Novatec Thru-Axle Hubs
    Using Novatec’s thru-axle hubs, the Thunder series e-bikes enjoy an enhanced stiffness and stability during high-speed rides and reduce the chance of scuffing and rubbing of the rotor. It also makes wheel assembly and disassembly easier.
