Thanks. Mostly I guess my rides are more like 20 to 30 but sometimes over 50 miles. Good idea to try it out but will need to travel a long way for that.Certainly, a lovely bike, one I would like as another addition, but it is aimed at the "city" type of user, and with its smallish wheels would not be my choice for many 45-mile rides.
Best take an extended demo/hire and do a 45 miler before committing, IMO.
