Fits just right.

Sizing Explained

At Ibis, we’re all about mak­ing sure every rid­er gets the per­fect fit and bal­anced ride.

In our pre­vi­ous four-size sys­tem, 80% of units sold were Medi­um and Large, fit­ting rid­ers between 55” and 60”. Now, with our new five-size sys­tem, we’ve intro­duced an Extra-Medi­um.” This new size slots per­fect­ly into the mid­dle of the bell curve.

Size Specific 1 v2
For rid­ers between sizes, the new options help you achieve a more tai­lored fit based on your pre­ferred top tube length or reach.

When select­ing a size, if you’re trans­fer­ring the fit from a pre­vi­ous bike, use top tube length, not reach, unless your pre­vi­ous bike has the same seat angle. Reach can be mis­lead­ing because it does­n’t account for how dif­fer­ent seat tube angles affect your posi­tion on the bike. The top tube length pro­vides a more accu­rate mea­sure­ment for main­tain­ing your rid­ing posi­tion, as it takes into account the changes in seat tube angle that can affect how the bike feels. 

For rid­ers between sizes, the new options help you achieve a more tai­lored fit based on your pre­ferred top tube length or reach. You might now opt for an Extra Medi­um or stick with a Large, depend­ing on your rid­ing style and fit pref­er­ence. If you crave sta­bil­i­ty for high-speed descents or rac­ing, you might size up. But if you love tight, Euro-style cor­ners and have that clas­sic BMX back­ground,” siz­ing down could be your jam.

With the lat­est iter­a­tions of the Rip­mo and Rip­ley, we focused on achiev­ing the per­fect bal­ance for each size by care­ful­ly con­sid­er­ing reach, top tube length, and seat tube angle. And because adjust­ing the seat tube angle for­ward — most nec­es­sary as we go up in sizes — has the largest impact on bike bal­ance, we’ve designed the Rip­mo and Rip­ley with size-spe­cif­ic every­thing: chain­stays, bot­tom brack­ets, and sus­pen­sion kine­mat­ics are all tai­lor-fit to ensure each size rides and feels the same.
