Can anyone recommend a really lightwieght bike that I can pedal most of the time and use motor to assist on hills but that doesnt cost a fortune! suitable for a smallish women.
Hi Lyndy and welcome to Pedelecs.
It's always a bit dangerous to ask the "Can anyone recommend?" question on here as the forum is populated by several ebike sellers and one is liable to be inundated with answers from them, explaining why they have just the product you need.
That said, they are mostly decent people who provide budget to mid-range priced bikes and offer solid warranty you may not get elsewhere. In asking for something lightweight, you need to understand that most ebikes which don't cost a fortune tend to be rather heavy but it depends on each individual's definition of light and heavy.
A dutch bike is a hard act to follow but there are quite a few built in that style though most that I can think of are seriously heavy. If you had indicated a firm budget limit, it would have been easy for forumites to exclude lots of bikes as simply being too expensive. For what it's worth, whenever anyone mentions light weight and pedal-assist to me, I immediately think of Cytronex. All their products are lightweight though the only model I can think of built for ladies is their Quick 4 Feminine. Their prices are upwards of £1500 I think now but you could check their website.
By and large, there is a price premium for light ebikes as there is for regular bikes so if you really need something very light, don't expect to get it for an equally light price! If your Sparta is unmanageable these days on account of weight, then adding a kit would only exacerbate that situation so I can't recommend that course. If you could be a little more specific about budget and how the bike would be used, members here would be better able to point you in the right direction. ie, Will you be commuting? Is the bike purely for leisure? Would a folder suffice?
Perhaps even more pertinently, where is your nearest ebike dealer? That may be a good starting point. If you don't know, then if you tell us which part of the country you're in, we will know.
