Used Wisper 905SE, purchased new in 2012. Ridden carefully and daily exclusively on residential roads up until around the start of COVID. Bike has been kept indoors and not ridden since then.Has the largest battery available for that model at the time: 16aH @ 37V. Does around 60 miles on one charge. Battery still appears to be in excellent condition and has been kept indoors in stable temperature conditions and regularly charged. Bike itself is in excellent condition but shows signs of not having been ridden for a couple of years; It could use some lubrication, possibly a replacement brake pad, and needs a new front tire inner tube.The bike came with optional parts, and every single part that it came with is included in the package along with all the paperwork that came with it.
