REDEFINING
THE BICYCLE
At Skarper, we didn’t set out to refine an existing technology — we set out to revolutionise what a bike can be. This is the story of how our R&D pushed boundaries, creating a whole new cycling experience.
YOUR BIKE, JUST BETTER.
Every cyclist knows the thrill of the perfect ride. The freedom of the open road, the challenge of the steep climb, the rush of the descent. But what if your bike could be more? What if it could conquer any hill, extend your range, take you to the office in a breeze, and still be the efficient machine you’ve always known and loved?
This is what we at Skarper aim to achieve: the ultimate eBike experience that enhances your ride without compromise.
We didn’t need to reinvent the wheel,
just the disc brake
At the core of Skarper click-on ebike system lies the vision to reinvent the most universal component on modern bicycles: the disc brake rotor. Skarper allows you to effortlessly transform your bike into an ebike and back again with a simple click.
Our DiskDrive rotor is just like the original disc brake rotor on your bike, seamlessly connecting via a centerlock or 6-bolt mount. In addition to providing the mounting system for the Skarper drive system, we’ve integrated a full gearbox, developed in collaboration with Red Bull Advanced Technologies.
WE’VE TAKEN CYCLING INNOVATION
TO THE FAST LANE
By collaborating with Oracle Red Bull Racing’s high-performance engineering division, Red Bull Advanced Technologies, we’ve combined world-class engineering with cycling passion. The result? An eBike drive system that’s not just cutting-edge – it’s revolutionary. We’ve pushed boundaries, refined every detail, and created something truly extraordinary. It’s the perfect blend of F1 precision and cycling innovation.
F1 Gears
Applying F1 gearbox knowledge to design the Skarper gearbox from the ground up
High Performance Materials
Leveraging expertise from Red Bull on gear materials to maximise power and durability
Built to last
Simulation combined with extensive testing to ensure a gearbox that will last
CLICK ON - OUR QUICK ATTACHMENT MECHANISM
Perfect Balance between Strength and Simplicity
We conquered the impossible!
Our mission: create a quick-attach mechanism that’s incredibly strong, effortlessly simple, and—here’s the kicker—leaves your bike untouched when removed. This non-negotiable requirement pushed us to the limit, but we refused to compromise. The result? Skarper – our engineering triumph that transforms your ride without altering your bike. We didn’t just overcome a challenge; we redefined what’s possible on two wheels!
To provide all the power you need whilst remaining energy efficient we developed DynamicClimb – a bespoke algorithm using a suite of wireless sensors, that measures the rider’s output, road incline and monitors drive unit parameters thousands of times a second.
DynamicClimb delivers a smooth and powerful ride.
Whether it’s accelerating ahead of traffic at a red light, or climbing that steep hill on the way home – DynamicClimb™ will provide the power you need.
REDEFINING RIDE EXPERIENCE
We aimed to create something truly unique in terms of performance. Here’s how we did it:
Sensor Innovation
We developed a pedal sensor that is significantly more responsive when compared to market standards. This allows us to replicate the smooth ride of a torque sensor without modifying your bike.
DynamicClimb® Algorithm
Our DynamicClimb algorithm detects current riding terrain and incline, adjusting power output accordingly and eliminating the need for constant mode changes.
Pause Mode
For cyclists who want more control, we introduced ‘pause mode’. Simply back pedal three times to send Skarper to conserve battery when electric assist is not needed. Want to reactivate motor power? Simply backpedal three times again to go back to assisted riding.
Tailored Power Modes
We’ve spent countless hours fine-tuning our power modes to ensure smooth transitions, responsive power drop-offs, and support when you need it most.
DESIGN PHILOSOPHY: SAFETY, UNIVERSALITY, AESTHETICS, POWER
Designing Skarper wasn’t just about performance; it had to look and feel right too.
Safety First
Ensuring foot and pedal clearance was crucial, influencing the depth and length of the Skarper unit.
Universal Fit
We aimed to fit as many bikes as possible, navigating the challenge of non-standardized frame designs and components.
Aesthetic Balance
We wanted Skarper to stand out while still integrating seamlessly onto your bike.
Maximizing Power
Fitting high torque capabilities into a compact, sealed, highly durable unit.
USER INTERFACE
Our UI journey started early, aiming for a minimalist design that delights users. We’ve gone through dozens of iterations, balancing visibility, intuitive use, and functionality.
