Are those just pro bikes pale rider or bikes aimed at leisure riders?
Thanks for the detailed reply.
The likes of the Orbea Gain and the new
Ribble ebike have the Ebikemotion hub motor and integrated battery in the down tube.
At about £2,500 they are aimed at leisure riders.
Higher up the roadie ebike scale is a crank drive called a Fazua, fitted to Cubes among others.
The motor and battery on that is detachable, bikes with it fitted cost £4,000+.
Still knocking around is the inside seatpost crank drive used by that Belgian lass who cheated in a CX race.
That has a separate battery pack, typically mounted in a saddle wedge pack, which means it's relatively cheap to replace.
Not sure of the price, last time I saw one it was £2,000+ as a retro fit.
