To get accurate and up-to-date information about the differences between the two models, I recommend visiting the manufacturer's official website or checking reputable retailers' websites for product details.

When comparing two different models, here are some common differences you might look for:

Design and Frame: The "Step-Through" in the name Sinch Step-Through Foldable Ebike suggests that the Step-Through model might have a frame design that allows riders to easily step through the frame, which can be more convenient for mounting and dismounting.

Riding Position: Step-Through models typically have a more upright and comfortable riding position, which can be preferred by riders who want a relaxed and ergonomic riding experience.

Frame Size: Step-Through models might have slightly different frame dimensions, catering to riders who prefer a specific frame size or geometry.

Accessibility: Step-Through models are often more accessible to a wider range of riders, including those who might have difficulty lifting their leg over a traditional frame.

Features: There could be differences in terms of features, such as the presence of a suspension system, integrated lights, fenders, racks, and more.
