Finding the correct bike for short tours and daily commutes
Consider repairing your current bicycle if you are happy with it. Especially if the frame and/or wheels are of high quality and still in good shape. For &lt;300€ you can only get a very cheap entry level bicycle. The same money will easily get you a pair of good tires, shifters, cables, chain, saddle, pedals, stem and handlebar to repair or upgrade your current bike. Repairing your current bicycle also makes sense if you plan to leave it at the train station since an old bicycle (with a good lock) is probably much less likely to get stolen than a brand new one (even if it’s cheap).

If you really want a new bicycle, I’d personally go for something less sedate than a city bike. Go for a hybrid, trekking bike or an MTB with rigid fork (i.e. without suspension). Avoid cheap suspension forks like the plague.
