# Cybervelo EK4 Folding Electric Bike, 20-Inch Fat Tires

The Cybervelo EK4 is a folding adult electric bike with 20-inch fat tires, front suspension, a removable battery, and a seven-speed drivetrain. The listing describes a 48V 20.8AH battery and up to 80 miles of range, but its range and speed claims vary across listing sections, so treat them as estimates rather than guaranteed riding results.

## Before you buy

- Listing details are contradictory or unconfirmed: motor power appears as 750W in the title but 1160 watts in the details, the speed is given as 20 MPH in the FAQ but 30+MPH elsewhere, and range is variously stated as up to 80 miles or 80-100 miles. The battery listing also gives 48V 20.8AH alongside 6 kwh and 5.33 hours, without explaining how these figures relate. Confirm the configuration and expected operating conditions for the specific listing before purchase. The listed minimum user height of 5.3 inches is implausible as written, so seek clarification rather than treating it as a usable fit measurement.

- Riders who want a seven-speed drivetrain and front suspension for commuting or occasional unpaved routes.
- Buyers able to confirm fit and realistic range needs before relying on the listing's performance claims.

- People who expect to carry a lightweight folding bike up stairs or for long distances.

## Customer feedback

Customer feedback describes the bike as well-constructed and easy to assemble, with positive reports about ride smoothness, hill handling, and beginner suitability. Battery life is mixed, with some customers satisfied and others saying it does not hold a charge as long as expected. That concern matters given the listing's extended range claims, which also vary by section and are stated to depend on riding conditions.

- Positive themes: Feedback mentions a smooth ride, hill handling, and suitability for first-time riders.
