The Jupiter Defiant is a folding electric bike built around 20-inch fat tires and a 750 W hub motor, so it can be carried in a trunk or closet and still roll over sand, gravel and snow. It folds at the frame and stem, runs disc brakes, and comes in white. Against rigid fat-tire e-bikes it trades some ride stability for portability, and against lighter folding e-bikes it trades weight and pedaling ease for motor power and float. It suits riders who want one bike for rough paths and mixed commutes and have room to store and lift a heavy folder.

Owner feedback on the Defiant centers on the motor's hill-climbing power and the fat tires' grip on loose surfaces, with folding convenience as the main draw. Complaints tend to focus on weight and on the bike's bulk once folded.
