Aluminum frame and the power-to-weight ratio

Using aluminum instead of steel reduces the bike's overall weight, translating into a better ratio between the 750W motor's power and the total weight carried. In practice, acceleration and handling are improved compared to a steel frame of the same power.

TW35H display with NFC function

The TW35H display shows speed, battery level and distance traveled, while the NFC function allows quick unlocking of the bike by tapping a compatible card or phone.

Recommendation: check the folding frame's locking mechanism periodically, especially under daily intensive use with the 750W motor.
