Your family commitments sound not too dissimilar to my own. I’ve gone through some high end machinery to justify me getting out a pedal around 12 hour shifts, commute, family and renovating a house. What have I now? Flat bar 29er SS. Bloody love it. Crappiest bike I’ve ever had . I treat it like a ginger step child. It needs something, it’ll get it when it finally breaks. After a horrid day I just go out and beast myself on it and throw it back in the garage afterwards unloved. I cycle with the kids on it. When I know I’m working late in the house, I come in from work and don’t even change clothes, straight out to ride. No water bottle, puncture repair kit or a care in the world. Like being 10 again . Just on your bike for the sake of it and I feel great afterwards. Tackle flooring a loft or whatever mundane tasks lie before me with a smile on my face. I would say I’m fitter because of the SS aspect and my bike handling skills are sharp as I have a go at anything now . No mechanical excuses to be made to cover lack of talent. Who cares if the bike takes a few knocks . I’m sure one day I’ll get my good bikes back, but for now it is more important to be a cyclist and getting out in the fresh air than it is to have the latest and greatest fad . Just get a bike that gets you out and enjoying that time . Surly Straggler BTW .
