Bottom line

The Jupiter Bike Discovery X7 is a folding e-bike with 20” wheels, a 350W motor, and a 244.8Wh battery. The bike’s relatively low weight and compact folding size make it a decent option for lifting and transportation. Reviewers appreciate the upright riding position, easy assembly, and comfortable ride over rough pavement. Downsides include lagging pedal assist, weak climbing ability, a rattling battery, and poor stability when folded. Reviewers also complain about the inaccurate battery readout and the lack of a taillight. Overall, experts feel the Discovery X7 offers good value as an entry-level e-folder for urban rides.
