I'm new to ebikes, relatively fit older lady 5'3" and am tossed between Bixtrix Step Thru Lite and Ride1U core 500/700. My biggest factor is price (like to stay under $1500) but also weight, as I often have to lift my bike to put it on my trailer hitch rack. Any suggestions that might help me decide? Service, etc.? I was thinking of calling local bike shop (they only carry Trek and Electra and unfortunately, Electra's comparable ebike is in infinite backorder, apparently) to see if they would work on either one. Any other suggestions similar in style/performacne and weight? Thanks.
