# Best Bike Advice > Accurate online bike fitting from home — calculates saddle height, setback, handlebar position, frame size and crank length in ~15 minutes. Best Bike Advice is an online bike fitting service. Users answer a questionnaire about their body, bike and riding goals from home. An algorithm developed by bike fitters, a sports physician and a mathematician — grounded in peer-reviewed research — calculates the ideal cycling position. The report gives exact numbers in millimetres for saddle height, saddle setback, handlebar position (frame reach and stack), frame size and crank length. The service is available in 14 languages.
