Description
The Dimanche 28 Urban OPEN takes Moustache's city bike and gives it an open frame. That single change matters every day: no more swinging a leg over the saddle. In a skirt, a long coat, with a bag on the rack, or simply when you're in a hurry at a light — you step through and go.
The open frame also opens the bike up to smaller riders. Three sizes are offered — XS, S and M — covering heights from 1.43 m to 1.81 m, where the standard frame starts higher.
Nothing else has been taken away. The Bosch Performance SX motor (55 Nm) stays compact and discreet: it adds just enough to erase neighbourhood climbs, without the sense of a bike pushing itself along. With the frame-integrated Bosch CompactTube 400 Wh battery, the package is rated for 50 to 60 km at 20.2 kg fully equipped — a weight that counts when you have to lift the bike up a step or roll it into a lift. The Bosch Purion 200 display sits in one corner of the bars and shows what matters.
The SR Suntour NRX32IL-D Air suspension fork and its 40 mm of travel absorb the cobbles, with rebound adjustment and a lockout to stiffen it on smooth roads. The Shimano CUES 10-speed drivetrain (11-39 cassette) and Shimano MT200 hydraulic disc brakes (180 mm front, 160 mm rear) round things out. Rack, mudguards and lights are fitted as standard.
Bosch Performance SX - 60 Nm
Lightness reinvented. The Bosch Performance Line SX is the motor that blurs the line between electric bike and muscle bike. With 60 Nm of torque and a featherweight, it is discreet where others are essential - for a driving experience that remains above all natural, agile and pleasant.
Designed for the thinnest frames and sportiest geometries, the SX is aimed at cyclists who want the electric boost without sacrificing the lightness or feel of the traditional bike. The assistance is lively and precise, perfectly dosed to enhance your pedaling without ever replacing it.
Bosch Compacttube 400 Wh
Lightness above all. The Bosch CompactTube 400 Wh is the battery designed for bicycles where every gram counts. With 400 Wh of capacity in a deliberately compact format, it is aimed at cyclists who favor the agility and maneuverability of a light bike, without giving up electric assistance on a daily basis. Its reduced format allows discreet integration into thinner frames and sportier geometries - where a standard PowerTube could not find its place. Ideal for urban outings and short to medium distance journeys, it offers most of the autonomy in the most compact format in the Bosch range.
Bosch Purion 200
The main thing, without distraction. The Bosch Purion 200 is the control screen designed for cyclists who want to keep their eyes on the road. Compact and integrated directly into the handlebars, it combines control and display in a single unit — clean, readable and perfectly within reach.
Its clear display shows essential information at a glance: assistance level, speed, remaining autonomy and battery status. No frills, no extras — just what you need to ride with confidence. Robust and weather-resistant, it faithfully accompanies every outing, whatever the weather.
Shimano, MT200, disque hydraulique
The introduction that does not disappoint. Shimano MT200 hydraulic disc brakes are the accessible benchmark for all cyclists who want to benefit from Shimano hydraulic reliability without compromising on safety. Powerful, progressive and modular braking, from the first press of the lever.
Designed for city bikes, trekking bikes and entry-level mountain bikes, they offer performance well above their price positioning. In dry weather or in the rain, the response is consistent and reassuring — ideal for cyclists who want to concentrate on their journey without thinking about their braking.
