I live in the countryside I am looking for a light weight e bike that is good on hills some of which are steep. The bi yeske needs okay to be light as i will use it to communte and my journey envoles train travel where i have to change platforms and so need to carry the bike.
Any sugestions please?
Basically, the trade-off is weight versus power. More power usually indicates bigger battery, motor, etc.
And how steep is 'steep'?
If you mean in the 10% range then a Boardman (Fazua-based), Orbea, or Ribble (ebikemotion-based) will be good choices in terms of weight - around 15-16Kg, and in your price range. All are 250W, i.e. legal.
If you mean 15% or steeper then you may struggle on a lightweight ebike unless you're also light and relatively fit.
You'll get up all hills easier with any ebike, but in the 15% hill bracket for a 250W bike there's a fair bit of muscle still needed to get you up, I've found.
