My husband and I are looking for step thru ebikes. We want one with a throttle, but not sure if thumb or half twist is best. We want 500w or greater 48v 13ah battery or higher and preferably Kevlar tires and all the other bells and whistles are good but not super important. We're both around 5'10" and are just leisure riders not commuters. We have kind of narrowed it down to igo elite 2, igo berr, igo Atwater or Bonaventure, orrr Radcity, or Thunder from Richmond ebikes. We live in Richmond BC and want to take the bikes on hilly holidays. I have tried to compare all the choices and they are all pretty similar so I guess I'm hoping for any suggestions on these models or any good experiences with these or any other step thrus. Thanks for your help.
