Trek District+ 4 R10 LS electric e-bike Bosch Performance 600W Dark Star 2027

The District+ 4 R10 LS Dark Star Trek is an electric hybrid bike designed to make everyday journeys simpler, more comfortable and more enjoyable. Thanks to its Alpha Platinum aluminium Lowstep frame, it makes getting on and off the bike particularly easy, whilst maintaining a comfortable and secure riding position. Whether you’re commuting to work, doing the shops, getting about in town or enjoying a weekend ride, the District+ 4 adapts easily to any situation.

Its 75 Nm Bosch Performance Line Smart System motor provides powerful and natural assistance, particularly when the road slopes uphill or when the bike is loaded. Combined with the 600 Wh PowerTube battery, it allows you to tackle both daily commutes and longer rides with confidence. The 10-speed CUES ‘ Shimano ’ drivetrain, meanwhile, offers a gear range wide enough to handle both flat terrain and undulating routes.

Trek The bike has also been designed for year-round use. The 60 mm suspension fork, suspension seatpost and 50 mm tyres enhance comfort on rough roads and compacted tracks. It comes fully equipped with lights, mudguards, a kickstand and a MIK-compatible luggage rack already fitted. All you need to do is get on the bike and enjoy the electric assistance.
