* Mountain bikes are sized differently to road bikes. Typically, they are sized in inches as the first MTBs were produced in the USA. European brands like Lapierre and Haibike like to use centimeters for all their bikes. The measurements of their mountain bikes doesn’t match their road bikes but is like a simple conversion from the inches measurement. This is why we have included cm measurements in brackets for the e mountain bike column.
