I've had the Smart bike for just over 2 weeks now but have been away for one of them so haven't had too much time to ride it. These are the good and bad points to it so far.
Carbon Belt Drive is almost maintainence free
Gears are smooth
Wide Tires are great for cycle paths
Integrated Lights ...
I love my tech and I'm loving cycling. I'll hopefully be loading up my panniers, riding off into the hills and stopping to do some work with mother nature and this bundle of tech as my office.
