Not sure which one fits? Here’s the check.

Height ranges are approximate starting points, not a guarantee of fit. Have your child sit on the bike in riding boots. They should be able to reach the ground comfortably, hold the bars without stretching, and operate the brakes with control. The E350 and E500 share a listed 19.3-inch seat height; the E800’s bigger wheels make an in-person fit check especially important. Height, confidence, and experience matter more than age alone. Start in the lowest mode.

Less wrenching. More riding.

First-bike fun.
Without the gas-bike routine.

No fuel runs, kick-starting, engine oil changes, or carburetor to fuss with. Charge the battery, choose a ride mode, and make time for another lap. Electric still needs regular checks: brakes, tires, chain, and fasteners.
