Discover the hand pump for bike and e-scooter by TnB. The pump is compatible with both Schrader and Presta valves. Its double piston conception allows more air to be released when squeezing. The pump is endowed with a lock system to block off the valve during the inflation. At the bottom of the pump, a handle is folded, to make the movement easier during the inflation. 23cm high when folded, its compact size makes it easy to transport, so you always have it near you when needed!
