I'm looking for my gf and I our first ebikes, need to be able to fold both up in back of my XT5 With seat down. Mostly concrete, light trails and occasional snow day (necessary as that's one of the main reasons I'm buying). Shop in ATL has the magnums but torn between that and the minis, and a bike shop in my town I have spoken to says they will assemble my minis. Also have an offer to buy used mini with about 500 miles with new tires grips pedals and spare tubes for around $800. Thoughts? I've done so much research and am overwhelmed haha
