For sale Folding electric bikes

For sale 2 x Fast4Ward Edge folding electric 20” bikes they are the same bike but have different seats and the one has mud guards and folding pedals. The one has been used but not abused where as the other has hardly been used. The battery on one has failed and needs repair, it was left switched on and went flat and I can’t get it to charge?
Fast4Ward is not a cheap Chinese brand, costing £950 each new and still available. I am selling the pair together for £600. Collection only from Halesowen B63.
Thanks
