CITY FRIENDLY FRAME WITH TONS OF AGILITY

PINION FOR WORRYLESS LIFE

MAHLE X30 MOTOR FOR REACH

LIGHTWEIGHT

The Serotonin was designed for the city - and the city doesn't wait. Tight junctions, last-minute turns, the gap that opens for exactly one second. The frame geometry keeps you upright, relaxed, and in control, while the agile handling means you're never fighting traffic. You're moving through it. Like you always knew where you were going.
Sealed, silent, and essentially indestructible. The Pinion gearbox has no exposed parts to wear, no cables to snap, no grease to clean. It shifts in any gear, at any speed, under any load. Set it and forget it - and spend that saved energy on the ride itself. The city is complicated enough without your bike adding to it.
The Mahle X30 quietly extends how far the city goes. Smooth, seamless support that feels like a tailwind rather than an engine - present when you need it, invisible when you don't. Up to 100km of range means the next neighbourhood, the longer route, the hill that usually puts you off - none of them are reasons to turn back.
Light enough to carry up the stairs. Light enough to forget it's electric. The Serotonin strips away everything that doesn't need to be there - and what's left is a bike that moves the way a city bike should. Effortlessly. The motor is optional. The lightness is not.
