OK so that could be distributed across a backpack and panniers. I would consider a battery located in the centre of the bike to provide safe weight distribution, but will leave others to advise re models as Im not up to date on what is available in the states.
low price but durability i.e. low...
Im sure you have got this sorted by now, but I just thought I would say that Ive started an owners group on Facebook to swop photos and related Pedego stories.
Up to a point.
I think its only fair to give them a chance to put things right.
If it goes well, publicly praise them. If it doesn't, then say so. This feedback educates other would be ebike buyers. As mentioned earlier by another poster, Amazon is a good role model.
I've just taken delivery of my new Cruiser and have both joined this forum and created a Facebook group called the "Pedego Owners Group" so that Pedegoers can share their photographs and community news on that social media platform as well as here.
