The first thing to do is contact the Momentum retailer where you collected the bike and inform them immediately – they may need to inspect the bike for you to ensure it is still safe to ride, so be prepared to return the bike to the retailer if they request it. Depending on the situation, charges may apply for excessive damage or usage beyond our recommended suggestion as based on our website – we do however understand that these bikes are designed to be ridden, so regular wear and tear is inevitable and will be taken into consideration.
