[!] alternative axles and hubs

[lumo]

as its impossible to get 14mm bmx hubs and axles here,
i finally bought 20mm linchpin axles with disc brake mounts;
therefore i cannot use the normal axle mount as discribed in the streetfighter plans.

here is my shematic plan for my mounting.
ill add pictures as soon as i got the parts (already got the hubs! :D)
good part on it is: i can use ALLOY as axle!
bad part 1 - ONE wheel costs about 215 USD (150 EURO)
brave monster hollow 20mm hub with 48 spokes (i cant spoke myself so spoking added me 25euro :( )

bad part 2 - you need a turning lathe to create the axle part.

write your comments, i am curious what you think about it.
the grey parts are alloy, the brownish are metal (M12 means that there is a screw thread)

greetings from austria - the country where you can get sh!t to build something (you need to import 95% of your needed parts from other countries)!

Odd, those 14mm hubs are a worldwide standard on almost all 20" bmx bikes now.

The 20mm hubs are nice though, and you also get a disc brake.

I did something slightly different, and it may cost you a lot less to do.

- Make the SF tabs as per the plans.
- Have some hollow 20mm tubes made with threads at one end
- Weld the tubes to the tabs.
- Use a bolt at the end of the tubes to secure the wheels.

thats a good suggestion! and will weight definitive less than a full 20mm rod of SS :D
my problem is that i actually cant estimate how thick something has to be so its strong enough.
i had a talk with someone at my workplace and he said with this way, i could hold 1000kg+
do you have an idea about that?

last but not least, secure the nut with a bolt at the end for security?

i am not sure how much weight/force you get on a wheel when you BUMP hard while driving down a hill.

the last tubes i welded on my scooter were thicker than 20mm and did not do their supposed job;

brad, did you test the tube stuff? and how thick were your tube walls?
