Racing bikes, or road bikes, are meant to go fast. They incorporate dropped handlebars, light construction, narrow tyres and gear ratios suited to long stretches of paved roads without significant climbs.
If you’d rather go off-road, consider a gravel bike. For uphill work, there are bikes more suited to climbing, which prioritise weight (or a lack of it) over comfort, but these lightweight machines can become extremely expensive, and can hardly be called entry-level.
