Is the seatpost a pump? Foldable e bike

The HIMO Z20 is a foldable electric bike with a built-in battery inside the frame and the seat post acting as a pump.

It weighs 21.6kg and fits into the trunk when folded. Shimano 6 gears, 250W rear wheel hub motor, and mechanical disc brakes are installed at the front and rear. The top speed is 25km/h, and the 10Ah lithium battery can run up to 80km after 5 hours of charging.

This product can be used in three ways, like a normal bicycle, in addition to using full power using the throttle and electric assist. The point is that you can quickly switch between the cool mode when riding casually in dual mode, and the dynamic mode with a single button when riding fast and sporty.

In addition, the saddle and seat post act as a pump. If you think the air pressure is low, you can use it anytime, anywhere. This product was also raised through crowdfunding site Indigo. More information on the product can be found here .
