Spiny 2: Turn Your Bike into a 750W E-bike in 3 Seconds

The easiest way from bike to e-bike. Clip on. Ride electric. Remove. Repeat. Spiny 2 transforms the bike you already own into a 750W e-bike, and then back into a regular bike, in seconds. Built for universal compatibility, with up to 90 km of range, 5 assistance modes, and just 2.2 kg to carry.

From Bike to E-Bike in Seconds

Power-up the bike you love! The frame, the feel, the familiarity. Spiny 2 keeps all of that and adds the one thing it's missing: electric assistance. Clip it onto your bike, and you're riding electric in seconds. It’s that simple.

Attach, Ride. Park, Remove.

Why pay thousands for an e-bike that can be stolen anytime? Built lightweight and removable, Spiny 2 is theft-proof by design. Detach it in seconds when you park, carry it with you, and ride home worry-free.

So Lightweight, Yet so Powerful.

It’s got the power! With a max assisted speed of 25 km/h, 750W peak power (250W nominal), and 35 Nm of torque, Spiny 2 redefines the boundaries of electric assistance. And yet, it stores away in your backpack as if it’s not even there.

500+ Riders Helped Us Build Spiny 2

Spiny 2 was developed by our engineering team after years of designing, testing, and improving the idea in the real world.

The first generation reached 500+ riders, giving us direct feedback on how Spiny 1 performed in everyday use and what we could make better.

That experience became the foundation for Spiny 2: our improved second generation, built around what real riders actually needed.

Absolutely Zero Drag

Starting an uphill ride? Got headwinds heading your way? Spiny’s sensors detect your effort in real time, and automatically engage/disengage the motor on and off the tire. That means zero drag while disengaged, and maximum power efficiency.

Power through rain, mud, and snow! Spiny’s patented high-traction grip maintains consistent contact with your tires, without any slipping or performance loss, in any weather condition. So you can keep with e-assistance, no matter what.

Arrive Fresh

Ride at your own pace, preserve your energy, and arrive fresh for whatever comes next. Morning meetings, client visits, evening plans… Spiny 2 will handle the effort, you just handle the steering.

Who We Are

Hey, I'm Marco, the founder of Spiny.


The idea for Spiny came from a simple frustration: I wanted electric assistance, but I didn’t want to give up my bike for a bulky, expensive e-bike. 

I tried conversion kits too, but most meant messy wires, complicated setup, permanent changes, and hassle to remove when parked.

So our team started working on a solution that could give you electric help when you need it, without taking away the feeling of riding your own bike. That idea became Spiny.
