I had look for many non-gear bikes like Rodeo, Wego, Duro, Activa, Access and Dio.
Going to purchase for my sis so need one with low height. So Dio and Rodeo is best but Rodeo has very low ground clearance of 115 mm so going to purchase Dio.
Taken test drive of Dio of model 2011 and 2002(which of my friend) both. Though 2002 model is old it was giving awesome pick up and power. He has never repaired his Dio since day one, its in very good condition.
