I really enjoy my Halfbike, a fun & challenging way to exercise and get around.
My main issue is that I must constantly be conscious of my foot placement on the pedals.
My heels get scrubbed, and sometimes sucked under the back wheels.
I wear a mens size 12 US shoe.
If I pedal where I'm most comfortable this happens, which is disappointing.
I must always pedal in slight awkwardness because I don't want the heels of my shoes to get sucked under the rear wheels and cause an accident or shoe damage.
Overall, great design and I'm happy!
