WARNING
If you mount a new tyre with another size than the standard tyre mounted, it might be possible that the clearance between the front of your shoe and the wheel will be reduced when you ride at reduced speed. Also observe the space between fork and frame. Risk of accident!
Treat your tyres with care. Always ride your bike with the prescribed tyre pressure (a) and check the pressure at regular intervals, at least once a week. Riding with too low or too high air pressure may make the tyre come off the rim or burst.
Clincher and folding tyres allowing an inflation pressure of five bars or more have to be mounted on hook bead rims, identifiable by the designation «C».
SAFETY INSTRUCTIONS
Observe the maximum pressure value of the rim. The pressure is dependent on the tyre width. You can find the values in the operating instructions of the rim or wheel manufac- turer.
Note that a pedelec weighs more and that your usual tyre pressure may be insufficient. A higher pressure gives a better riding stability and reduces the risk of a puncture. The minimum and maximum pressure (in bar or PSI) is indicated on the tyre side.
VALVES
There are three valve types in general use on URBAN JUNGLE city and trekking bikes:
1. Sclaverand or Presta valve (b): This valve is nowadays used on almost all types of bikes. It is designed to withstand extremely high pressures.
2. Schrader or American valve (c): This is an adapted car tyre valve.
3. Dunlop or Woods valve (d): The usual valve.
All valve types come with a plastic cap to protect them from dirt. The Schrader and Dunlop valve can be inflated with a suitable pump directly after removing the protective cap.
