Moustache Dimanche 28 Urban

The Dimanche 28 Urban is the light one. At around 20 kg it is among the lightest fully-equipped electric bikes you can find — a fast, agile urban bike that still feels like a bicycle rather than a machine. Bosch’s featherweight SX motor gives it a natural, responsive push without the weight of a bigger system, and a suspension fork, wide tyres and a dropper post keep it comfortable and practical. For riders coming from an ordinary bike who don’t want to give that feeling up, this is the Moustache to look at.

Electric, but it still feels like a bike

The 28 Urban is for riders who want assistance without the heft — people moving from a normal bike who’d rather not step into the heavier, more powerful e-bike category. At around 20 kg it stays light and lively: quick to accelerate, easy to flick through traffic, and simple to lift up a step or onto a rack. The Bosch SX motor is so light and natural you half forget it’s there, filling in behind your effort rather than taking over.

Light doesn’t mean bare, though. A suspension fork and high-volume tyres smooth out broken tarmac and cobbles. The dropper post lowers the saddle at the touch of a lever — handy as you come to a stop, and quick to set right if someone else rides the bike too. And integrated lights, mudguards and a rack make it genuinely practical. It’s a sporty, spirited urban bike that happens to be ready for the daily commute.

Light, and properly equipped

Moustache builds the 28 Urban around a hydroformed 6061 alloy frame with the Bosch CompactTube battery hidden in the down tube. The Performance Line SX is Bosch’s motor for light bikes: it responds to how hard you pedal, so the assistance feels natural rather than forceful, and the simple Purion 200 display stays out of your way. If you want more range, an optional PowerMore battery adds another 250 Wh.

Comfort comes from an SR Suntour air fork with 40 mm of travel, the dropper seatpost, and wide Schwalbe G-One Comp tyres that roll quickly on tarmac and keep their grip on wet roads and towpaths. Shimano hydraulic disc brakes and a wide-range Shimano CUES drivetrain take care of stopping and climbing, and the Supernova front light, mudguards and QL3 rack are all fitted as standard.

Why the weight matters

Most fully-equipped city e-bikes weigh nearer 28 kg; the Dimanche 28 Urban comes in around 20 kg. That difference changes how the bike feels in every way — it’s more eager to accelerate, easier to lean into a corner, and far less of a wrestle when you need to lift it up a kerb, onto a train, or into a hallway.

The Bosch SX motor is central to that. It’s Bosch’s lightest drive unit, tuned to feel intuitive rather than forceful — the assistance builds with your own effort, so the bike feels fast rather than pushy. If you love the way a normal bike rides and just want a helping hand on the hills and headwinds, this is the setup that keeps that feeling intact.

Dimanche 28 Urban, or something else?

The 28 Urban is the flat-bar, fast-urban member of the light Dimanche family. If you’d rather have drop bars and lean towards gravel and longer rides, the Dimanche 29.2 is the gravel-focused sibling on the same light platform. And if you want more motor and a more upright, rugged all-rounder for mixed on- and off-road riding, the Xroad 2 trades some lightness for grunt and suspension. But if what you want is a light, sporty city bike that still feels like a bicycle, the 28 Urban is hard to beat. Come and lift one — the weight tells the story.

FAQs

Around 20 kg — light for a fully-equipped e-bike, where 28 kg is more typical. The lower weight makes the bike feel more agile and natural to ride, and far easier to lift up steps, onto a rack or into a hallway. If you value the way a normal bike handles, or you simply have to carry it at either end of your journey, the weight is the single biggest reason to choose it.

For most riders, yes. The SX gives natural, responsive assistance tuned for light bikes — it builds smoothly with your effort rather than surging, which is what keeps the bike feeling like a bicycle. It has less outright torque than Bosch’s bigger motors, so if you regularly climb very steep hills fully loaded, a more powerful bike like the Xroad 2 may suit you better. For everyday city riding, the SX is ideal.

It’s one of the best choices for exactly that. It keeps the light, lively feel of an ordinary bike and simply adds a gentle, natural helping hand — no heavy frame, no overpowering motor. Riders who’ve been put off by how substantial many e-bikes feel tend to get on with the 28 Urban straight away.

Yes — the high-volume Schwalbe G-One Comp tyres and the suspension fork handle canal towpaths, wet roads and light gravel comfortably. It’s not a mountain bike, but for the mixed surfaces of city and edge-of-city riding it’s very capable. If you want to head off-road more seriously, look at the Xroad instead.
