All e-bikes sizes vary depending on how manufacturers make their measurements and one medium size frame may well be a few centimetres bigger than another so this table is only to be used as a rough guide. On the whole Road bikes are usually measured in centimetres and are a size higher. Mountain bikes are measured in inches and are similar to hybrids. Hybrid bikes can be measured in both but in all cases it is best to look at the manufacturers sizing information and it is useful to also take a measurement of your inside leg to get the best fit. If you fall between sizes it is sometimes recommended that a smaller size may be best as the saddle can then be raised to get the perfect fit.
