Even velomobiles are subject to a certain amount of wear. Not only the tyre wears out over time. The chain, sprocket and chainrings also wear out. The bearings of the wheels need to be checked every now and then. The gear and brake cables also need attention to function properly. Many components can also show signs of fatigue over time. For example, spoke tension should be checked regularly to avoid breakage. All of these issues affect function and reduce riding enjoyment. In the worst case, wear and tear can even endanger safety, e.g. in the case of faults in the brakes or cracks in the rims. To prevent this, regular inspections are advisable. These roughly include checking the chassis and running gear for damage, a functional check of all moving parts, lines, bearings and adjusting the gears and brakes, and a test drive. Anything beyond this, such as the replacement of worn parts, generates additional costs. A distinction is then also made here between repair and inspection.
