Sizing chart

All Xtracycle frames from model year 2018 forward come in one size.

For 2021 model year bikes (all Shimano STEPS EP8 bikes), all bikes come with a 450mm long seat post that can fit riders of various heights. When you choose the size of the FitKit on the 2021 bikes, you are only choosing the stem size. This is the part that connects your handlebars to your fork. The stem sizes are small (60mm), medium (90mm) or large (120mm).

For 2018-2020 model year bikes (the Swoop non-electric and bikes with Bosch systems), when you choose the size of the FitKit, you are choosing both your seat post length and the stem size. The sizes are small (300mm seat post, 60mm stem), medium (400mm seat post, 90mm stem) or large (450mm seat post, 120mm stem).

Here are the FitKit sizes we recommend for each bike model based on the rider’s height.

If the rider is…	and they are riding a…	they should use this FitKit:
5′ to 5’5″	RFA	Small
5’6″ to 5’11”	RFA	Medium
6′ to 6’4″	RFA	Large
5′ to 5’5″	Stoker	(Stoker is not recommended)
5’6″ to 5’11”	Stoker	Medium
6′ to 6’4″	Stoker	Large
5′ to 5’5″	Swoop	Small
5’6″ to 5’11”	Swoop	Medium
5’9″ to 6’4″	Swoop	Large
