Here are the key differences between the Kingsmith WalkingPad R1 and the WalkingPad R2:

## Folding Mechanism
- The WalkingPad R2 has a single-fold design, allowing it to be folded in half for storage, while the R1 Pro is noted for its double-fold feature, which further reduces the storage space required.

## Handle Adjustability and Mode
- The WalkingPad R2 has adjustable handrails that can be lowered for walking mode (up to 3.7 mph or 6 km/h) and raised for running mode (up to 7.5 mph or 12 km/h). The R1 Pro also has adjustable handles, but the specific speed limits and modes may vary slightly.

## Storage and Portability
- Both models are designed for space-saving storage, but the R2's single-fold mechanism makes it slightly less compact when folded compared to the R1 Pro's double-fold design. However, the R2 still offers a very compact storage solution with a vertical storage option.

## Motor and Noise Level
- Both treadmills use a brushless motor, but the R2 is specifically noted for its quiet operation, with an idling noise level of 65 decibels. While the R1 Pro also has a quiet motor, the exact noise level is not specified in the same detail.

## Control Methods
- Both models offer multiple control methods, including a remote control, the KS Fit App, and foot-sensing control. However, the R2's control interface and additional features like the dedicated phone and tablet slot may differ slightly from the R1 Pro.

## General Design and Aesthetics
- The R2 has an integrated aluminium alloy frame and a basic yet robust shape, while the R1 Pro may have similar construction but with potentially different aesthetic details and awards for design.

These differences highlight the unique features and improvements in each model, particularly in terms of folding mechanism, storage, and control methods.
