Which one does fit on my bike? It’s a bit complicated since there’re a couple of models.
So, for this time, I’m going to focus on only 1x setup to give you guys specific answers.

(This is the show bike by OTSO and SWIFT INDUSTRIES from 2025 MADE SHOW. I feel a bit familiar with those Ti fork, crmo crank and Swift Industries bike bags…)
First of all, cyber crank GR-II which is used for the OTSO above.
Here’s the list of the bikes which is compatible with it.
SURLY：CROSS CHECK・STRAGGLER・PACK RAT・PREAMBLE・LONG HAUL TRUCKER・DISC TRUCKER
CRUST：ROMANCEUR・BOMBORAseries・LIGHTNING BOLT CANTI,DISC・STUPID TOURIST
MASH：ALL ROAD
VELO ORANGE：POLYVALENT・PASS HUNTER・NEUTRINO
BLACK MOUNTAIN：MONSTERCROSS・MOD ZERO・MCD
RON’S BIKES：ALUMAX
SINGULAR:PEREGRINE・KITE
WILDE：RAMBLER
ALL CITY：SPACE HORSE series・SUPER PROFESSIONAL
And also, it goes great with grave bikes, cyclocross and old MTBs. (In short, it goes great with 135mm or 142mm rear spacing.)
The chainline would be 46.5mm with usual 6mm offset chainring, so it should be working well with the bikes above.
The next one is cyber crank OR-II.
SURLY：KARATE MONKEY・LOWSIDE・GRAPPLER・KLAMPUS
CRUST：Not compatible
BLACK MOUNTAIN：LA CABRA (but the clearance between the arm and chain stay would be so tight.)
WILDE：SUPER TRAMP
Compatible with most of Boost chainline bikes.
(You can use it for STRIDSLAND Beachcomber and CRUST Evasion by putting the chainring on the middle like Santa’s bike.)
The last one is cyber crank ST-II.
This model uses a square taper bottom bracket, so you can adjust the axle length as needed to fit various bikes.
I’m sure that every single bike compatible with GR-II goes great with ST-II as well.
But, I think you should avoid from using it for the bike with 148mm rear spacing since there’re not enough clearance between the arm and chain stay.
CRUST Evasion, Evasion Lite, Wombat, STRIDSLAND Beachcomber are not compatible with both GR-II and OR-II, but ST-II works with 73mm/118mm or 73mm/122mm bottom bracket.
I think there’re nothing from CYBER CRANK to fit on CRUST scapegoat. It’s a bit hard to fit on the same kind of fat bikes, but it might be working with 1x setup…
For track bikes, this ST-II works well with around 110mm bottom bracket.
⚠️These direct mount cranks are not suitable for fixed gear. (fixing bolts are getting loose while riding.)
