Consolation and efficiency are my two main motivators. If the bike does not match nicely or causes you ache, or it does not carry out to your liking for the applying (geometry), you are not going to wish to journey it and the way a lot you spent or the way it seems will not matter.
(it might be completely different if this was an off-the-cuff bike, or a cruiser, or a grocery getter. In that case “fashion” is an appropriate precedence. But when train and health is the objective, you need to shift your priorities. You’ll be able to at all times Bling it up or add coloration accents to your liking over time to customise it.)
Price range is nearly at all times an element too. I typically advocate for getting one of the best bike you may afford. Across the $1k worth level, or under, I feel there’s significantly better worth in shopping for a used bike.
