HI, which accelerometer do u suggest to determine the deceleration of a bicycle??

thanks a lot

 

The most straightforward accelerometer I know of is the MEMSIC 2125.

You can purchase the module from Sparkfun.com or Radioshack. Other places sell the module as well.

is a single-axis one enough to measure deceleration in this case?

 

If you are only measuring 1 axis, then yes.
