Im building a single speed mini velo with 20inch bmx wheels.
Right now Im at the process on building its wheels and I was thinking on getting bmx hubs instead of ‘normal size bike wheel hubs’ because they are cheaper.
Are there any downsides on doing that? Is there a substantial difference between these two types or it is just a marketing thing?
I’ve built only a few wheels, but am autistic, so geek out on getting it right.
You want several requirements met:
-
IF it is a drive-wheel, OR it is a hub/disc brake, THEN you want a big-enough hub spoke-circle, for the angular transmission-of-forces, and you cannot use radial-spoking on that wheel.
-
you want the bearings & races to be robust enough for YOUR purposes
-
you want enough distance between the hub’s spoke-circles for any tilting-the-bike-while-upright-riding, or side-applied force from the hub’s perspective, so the force has enough trigonometric geometry to not stretch/crack/bend/deform your spokes, or mangle your wheel.
I wish the thru-axles were normal in all sizes, and all standardized to a few diff diameters, front & back, with different axle-widths available, too.
Weight isn’t a factor for any of the geometrics I identified, nor is cost.
Those are independent dimensions of consideration.
