I was torn between a hybrid and road bike also. I went with the hybrid in the end as I primarily needed a bike to get to work and back, I use the cycle lanes when they actually make sense so had to factor in dropping off and mounting curbs plus the fact they’re generally muddy or slippery so skinny slicks are not suitable. That said I did change the tyres to cityjets as it is mostly road riding. I also changed the pedals so I could use cleats but found a set which would allow me to wear normal shoes also. It’s a compromise as I use the bike as an all rounder but I’m happy with it, I can do family bike rides and fast commuting (when my fitness level allows as If I’ve not ridden in awhile I struggle with the higher gears).
I have disc brakes but find them annoying as they squeal and act strangely in the wet, another reason why hybrid made more sense as I fitted mud guards to limit the amount of road dirt I was covered in by the time I got to work, not really a problem as I wore padded shorts and a proper top and changed when I got there. Seemed silly having a road bike and ruining the aerodynamics by fitting mud guards.
Milage wise it wasn’t much, 16 mile round trip, if I fancy a ride on my own I won’t do more than 10 as I get bored and think of all the other things I could be doing instead, which I won’t actually do anyway because I’m lazy and unmotivated. During lock down I took my 7 year old on bike rides to keep his fitness up as he wasn’t able to play football, he did really well as he rode a single speed bmx/mountain bike and was maxing out around 6 miles. He wants a new bike with gears but I think it can wait until spring now.
