Batch eCB.3 commuter e-bike launches with 28 mph pedal assist, 720 Wh battery, and step-through comfort
Aiming squarely at urban riders and daily commuters, US-based e-bike maker Batch has unveiled the eCB.3, a sleek step-through electric bike that blends comfort, control, and speed. With a 28 mph (45 km/h) pedal-assist top speed and a generous 720 Wh battery, it’s built to cover busy weekdays and weekend errands with ease.
The eCB.3 starts with a 6061 hydroformed aluminum step-through frame for easy mounting and confident handling in city traffic. Up front, a Zoom hydraulic suspension fork with 80 mm of travel helps smooth out potholes, cracked pavement, and gravel paths. Wide Kenda 27.5 x 2.4-inch tires add stability and grip, while Tektro HD-M275 hydraulic disc brakes paired with 180 mm rotors deliver reliable stopping power in all weather.
For gearing, Batch chose a Shimano Altus 8-speed drivetrain, giving riders simple, dependable shifts across flats and hills. Power comes from a 500 W Vinka rear hub motor that assists up to 28 mph, ideal for keeping pace on bike lanes and shaving time off commutes. The 48 V, 15 Ah battery totals 720 Wh, a sizable capacity for this class; while Batch hasn’t published an official range, the battery size suggests solid day-to-day distance for most riders.
On the cockpit, the KDS KD-716 LCD display presents key ride data at a glance, including speed, distance, mode, selected gear, and battery level. There’s no companion app, keeping the experience straightforward and focused on the ride.
