I want a new bike to replace my carrea from last summer & have decided i would like one of these two bikes. I would just like people's advice on which is the better bike for me ?.

I ride about for at least an hour nearly every sunny day with 70% of the time on smooth cycle lanes & the other 30% of the time on bumpy trails & beaten tracks. I know next to nothing about bikes (i just enjoy riding them) so any opinions on the bikes or specs of the bikes would be welcome
