Anyone knows how to determine the size of a halfbike type 2?

I'm considering buying a second hand halfbike type 2 before going all in on a type 3 but the seller doesn't know what size it is. Does anyone know how to determine the size of the thing (measurements etc) and is there a diy option if it's an S (I'm 1,87m)?

Yes, you'll need to measure the length from the handlebar to the ground :) For example a distance measured at around 110cm should be a size M and the difference between sizes is about 6cm. You can buy the bigger handlebar, just drop us a line at hello@halfbikes.com
