Nice job. Very clever idea. Does the loop that holds the handlebar grip "unfasten" or is it fixed?
If it's fixed could you make one with some kind of carabiner end? I've got Barkbusters on both of my bikes so you can't slip anything onto the end of the bar as it's "captured".
Streets still unseen, we'll find somehow. No time is better than now.
