someone did attach a brake to their stem, on the front park, how are you going to be able to use it thought?
and what handlebar is that, or did that come with the bike?
You can use the brake either one hand on the bars and the other pushing the lever forwards. Or both hands on the bars, lean forwards and brake with your crotch (but moving your weight to the front and hitting the front brake is a good chance to kiss the asphalt :))
The bars came with the bike, just the standard english-built "Dawes" bars.
Are you going to install a back brake too?
ammmmmn, no.
