The Bosch pump should be able to pump up to 10.30 bar, laugh... I've had problems and concerns with the Bosch Home & Garden EasyPump (10.30 bar) since the beginning. It should be able to pump up to 10.30 bar... I only pump my MTB tyres at 2.9 bar and the pump has extreme problems and takes forever. That can't be right? It also smells slightly of electronic combustion. Either the product is very bad or my Bosch Home & Garden EasyPump has been defective since the beginning.
