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.
