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.
Less E, More Bike
Our Design Philosophy for Thunder 1 ST
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.
Less E, More Bike
Our Design Philosophy for Thunder 1 ST
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.
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.
