5.2 Padangų priežiūra
- Reguliariai tikrinkite padangų slėgį ir pripūskite jas iki rekomenduojamo slėgio (PSI) (nurodyto ant padangos šoninės sienelės).

- Patikrinkite stabdžių kaladėles, ar jos nėra susidėvėjusios, ir prireikus pakeiskite jas.
- Įsitikinkite, kad stabdžių svirtys reaguoja į judesius ir užtikrina pakankamą stabdymo jėgą. Jei reikia, sureguliuokite troso įtempimą.
5.4 Bendras valymas ir tepimas
- Reguliariai valykite dviratį naudodami reklamąamp šluoste. Venkite naudoti aukšto slėgio plovimo įrenginius tiesiai ant elektrinių komponentų.
