Batch Bicycles eCB.3 27.5 - Slate Bronze
Batch Bicycles eCB.3 27.5
The all-new Batch eCB.3 is made for riders who want comfort, ease, and a little extra zip in their everyday routine. Outfitted with a powerful 500W Class 3 Vinka rear hub motor, this electric comfort bike provides pedal-assist support up to 28 MPH or 20 MPH with the throttle, helping you cruise longer, climb easier, and ride with confidence — whether you're commuting, running errands, or exploring on the weekend.
Built around a step-thru alloy frame, the eCB.3 offers easy on-and-off access with a relaxed, upright riding position. The Zoom hydraulic suspension fork smooths out cracks and bumps in the road, while wide 2.4” tires add stability and traction. With a Shimano 8-speed drivetrain, Tektro hydraulic disc brakes, and anatomical comfort features, it’s everything you want in an e-bike — approachable, enjoyable, and ready to roll.
Key Features:
- Vinka E-Power System – 500W Vinka RH30 rear hub motor delivers efficient pedal-assist performance up to 28mph.
- Hydraulic Suspension Fork – Zoom 862S fork with 80mm travel smooths out bumpy streets and gravel paths.
- Comfort-First Geometry – Step-thru alloy frame offers easy mounting and a relaxed upright fit for casual cruising.
- Smooth 8-Speed Drivetrain – Shimano Altus shifting provides reliable gearing across flats, hills, and everything in between.
