How do I find the correct frame size for my e-mountain bike? Let me tell you.
The right frame size:
Frame size body size
XS / 14-15” <160 cm
S / 16-17” 160-170cm
M / 18-19” 170-180cm
L / 20-21” 180-190cm
XL / 22-23” >190cm
For a long time, the seat tube length was considered “the measure of all things” for size determination in the MTB sector. Since the seat height is primarily adjusted via (long) Vario seat posts, the value has lost importance – especially since most manufacturers try to draw the seat tube as short as possible. The top tube length is no longer as crucial for sizing. The “seat length” is regulated more via the stem. Instead, the so-called Reach value says more about the length of the front frame triangle. The longer the reach, the better you are usually integrated into the bike. However, very long-reach values often require acclimation or an experienced hand. But how do you find the right size now?
Almost all manufacturers no longer specify this in centimeters or inches but use “T-shirt sizes” from XXS to XXL, with the selection of most E-MTBs limited to four sizes. And indeed: If you are “normally built” and choose your clothing size, you will also usually find the right E-MTB. Many manufacturers also offer sophisticated “size finders” on their websites. And the trained specialist dealer will also help you find the right size.

Ive seen that you can get a professional bike fit at 99Bikes. Not sure of they're any good but they seem to be common... so, worth a try?

Astonishing that a post I made nearly 10 years ago is still alive.

Numbers are nothing in frame sizes. My first real fit many years ago had me on a 58cm steel frame road bike (Miyata 1200), and it fitted beautifully. My current bike is a Cannondale Synapse Carbon 105 and a 54cm frame fits me beautifully. I recently road tested a Trek E-road bike with a 56cm frame size and it fitted so spot on. So as for choosing the correct frame size, go for a test ride and see what fits, and don't be scared to ask for a different stem length if the reach to the bars is not quite right.
