Bugaboo Frog: I the Bugaboo Frog's handlebar reversible?

Hi,

Yes, you can, the Bugaboo Frog handle, as the predecessor of the Bugaboo's Cameleon line of strollers, does feature a reversible handlebar.

The push with the handle reversed is, however not the most comfortable one - I'd only suggest that for short periods of time to literally only overcome bumps or holes on a bad patch of terrain.
