Care & Maintenance

Used bikes should be handled with care to maintain performance and safety: avoid over-tightening bolts (use a torque wrench), inspect the frame regularly for cracks or damage, clean gently with mild soap and water, keep the chain lubricated, and get an annual tune-up to catch wear and ensure safe performance.

Size & Fit

This sizing guide offers a general starting point based on rider height. Since body proportions and frame geometries vary by brand, use it only as a reference — for the best fit, check specific brand charts or consult a bike fitter.
