We are a pair of active pensioners who would like two folding ebikes which are; step through, will carry our shopping, are not prone to rusting in the wet, we would prefer hub gears (because derailleur are vulnerable to knocks in our confined storage space) and as light as possible for about £1,000. So far we have looked at an Ezego Fold LS and a Wisper 806. Can anyone offer any further advice or suggestions, please?
