Product detailed description
eRokk B70 City combines an easy step-through frame and upright riding position with equipment for commutes and leisure rides. Wide tyres add confidence on asphalt and firm paths, while the Bosch CX motor helps with starts and climbs. Easy access to the saddle and comfortable handling in town are central to this model.
Help when the road rises
The Bosch Performance Line CX Smart System mid-drive delivers 85 Nm. Assistance responds to your pedalling effort, feeling natural at a relaxed pace and giving stronger help on climbs. The compact Bosch Purion 200 shows ride information and lets you change modes. In the Bosch eBike Flow app you can tailor assistance for relaxed town riding or a loaded bike, plan routes and update the system.
Energy for daily use and longer rides
The integrated Bosch PowerTube battery has a 625 Wh capacity. It gives you room for a longer outing or several shorter journeys between charges. Actual range varies with terrain, assistance level, weather and load.
Comfort and control across surfaces
The RST Blaze coil fork has 100 mm of travel to take the edge off everyday bumps. WTB Groov-E Comp 27.5 × 2.40″ tyres add stability on paving and gravel. Shimano ESSA eight-speed gearing with an 11–45-tooth cassette lets you adjust cadence for climbs and faster flats, while Shimano MT200 hydraulic brakes help control speed.
Useful equipment already fitted
An AXA Blueline 30 front light and Spanninga rear light improve visibility; full-cover mudguards help keep spray off. The AVS-compatible rack has a 27 kg load limit, a kickstand makes stops easier, and the AXA Block XXL frame lock is handy for short pauses. These parts are fitted to the bike.
