LEMMO Zero

A carry-on-sized e-bike by Christian Zanzotti and Lemmo that unfolds in seconds to conquer the last mile.

Berlin, June. The S-Bahn doors slide apart and a rider steps out carrying what looks like a carbon rail no longer than a tenor sax case. Two quick hinges click, 20-inch wheels swing into place, and before the departure whistle sounds she’s rolling toward the exit ramp—traffic-free, seat still warm from the train.

Built around one idea—fold first, ride second

Most folding bikes disguise their joints; LEMMO Zero puts them in charge. Italian designer Christian Zanzotti shaped the entire frame around a laminated-carbon spine that weighs just 10.5 kg. When collapsed, the wheels nest inside the triangle so neatly that the whole bike slips into a 28-inch suitcase—no oversized baggage tag, no quarrel with the flight attendant.

Power that leaves the platform with you

Slide the 159 Wh Smartpac off its seat-tube dock and it becomes a 2 kg USB-C power bank, topping up a laptop while you wait for a connection. Clip it back on and you have enough charge for 30–40 km of pedal-assist range—plenty for the daily zig-zag between home, office, and the late show at Yorckstraße.

Two modes, one cadence

Analog mode feels like a clean-lined mini-velo: direct, almost playful. Tap the rear-hub motor and headwinds flatten out; bridges shorten. All cables, wiring, and hinge hardware live inside the central spine, so what you see is a single dart of metal under tension—no clutter, nothing to snag on a coat hem.
From car boot to cabin aisle. For drivers who park outside the Ring and cycle the last mile, there’s a NIO Edition that syncs battery and ride data with the Chinese EV maker’s “4 + 2” ecosystem. Pop a hatch, scan the dashboard, and you know exactly how many kilometres of assist you have left before you even touch the handlebars.

Why it matters

Cities are shrinking parking spots while growing apartment towers. By designing a bicycle that behaves like luggage—easy to hoist, impossible to bruise fellow passengers—Zanzotti and Lemmo extend the practical radius of human-powered movement without adding another scooter to the sidewalk. It’s not tech theatre; it’s a quiet recalibration of the “too far to walk, too short to drive” dilemma.

Late evening on Tempelhofer Feld, you might spot the same rider cruising the old runway, Smartpac juicing her phone as the sun drops behind the hangars. When she wheels home, the bike folds smaller than the record crate by her couch—ready for the morning train, and the next short hop the city throws at her.

LEMMO Zero made its debut in Shanghai on 20 June 2025 and heads to Eurobike Frankfurt a week later—an East-meets-West itinerary that mirrors the bike’s aim: knit together the disconnected pieces of urban travel.
