I have run a Woosh Sirocco CD (~3 yrs) and a Giant LA Free (~7 yrs) ragged up hill and down dale on the way to and from work (9 miles each way) and now need a new e-bike. I prefer the lighter bikes (hills are v steep) & clearly need to consider investing in something that can take punishment. However, I don't go off road and find MTB style bikes are often too slow. I would be grateful for any suggestions please.
