Overview
This is the EK12-cbv-BBAI configuration of the CBVELO fat tire step-through electric bike, paired with a 48V 20Ah removable battery and 20 x 4.0 inch tires for stability on loose or uneven ground.
Like other CBVELO listings in this range, the rating rests on a single review, so it reads as early feedback rather than a settled track record. What distinguishes the model is the low step-through frame combined with a reinforced rear rack built to carry a small passenger.
- 48V 20Ah removable, lockable battery
- 20 x 4.0 inch fat tires
- Built-in headlight and rear reflectors
- Listed as UL certified
Who it's for
Best suited to riders who value an easy step-through mount, such as beginners or seniors, and who might occasionally carry a child or small passenger. Not the choice for someone wanting a light, minimalist commuter bike.
Pros and cons
- Low step-through frame simplifies mounting
- Battery detaches for indoor charging
- Rear rack built for a small passenger
- Wide tires for sand, gravel, dirt, and snow
- Rating is based on one review only
- Passenger seat and foot pegs are listed as optional
Performance notes
Pedal assist and throttle modes are both available, switchable from the LCD display alongside speed and battery readouts. The wide 4.0 inch tires are pitched as natural shock absorption over bumps, and the removable 48V 20Ah pack is rated for up to 80 miles.
