I have been running the Creo for a couple of months now. I got the Carbon Comp (14kg and £5400) and have swapped out a few bits to bring weight down to 12.5kg. This cost me £1000 but was far cheaper than buying the Expert at £7500 or S-Works at £11k !!! It is really an awesome bike and I love it bit. The motor is so smooth and you barely feel when it disengages. Longest ride I have done is 60 miles so far, just on standard battery. I do have the extender, but rarely use it. With the bike being lighter, I do tend to run along with the motor switched off until I need it. I reckon could easily get 100 mile ride out of the battery doing this as did 30 miles on 10% the other day. One thing to watch on these is that they have a few bespoke parts. For example changing the cranks arms is very difficult and the wheel choice is very awkward due to 12x 110 boost front. Only found a few wheel to fit. Also had fun with the front bolt thru as 12x 110 does not exist according to the internet and ended up having to make one from a cut down 12 x142. Overall, I still love this bike and it is my go to machine over my other 2 bikes (non electric Roubaix and Tarmac)
