MBBO Class 2 - ALiEN FiRE - DONE!

[GuitarlCarl]

Well if it's only bolt on, this bike could almost squeeze into Class 1.
But, in my mind its a Super Modified, so that's where I'm going!
And some point there's going to have to be some cutting, drilling,
and or welding involved to get a seat mounted...
You see, it's a flip bike.

Here's the mockup with the correct size wheels on it.
Alien tech allows for the floating seat, and invisible BB...
It started out as a Roadmaster women's MTB. I death rayed all the stickers off of it except the headbadge which looks good upside down, I'll get a pic eventually. I like the way the flip rakes the forks out forward, I think the lines on this one look natural.

I don't trust Alien tech
So I'm fabbing a BB.

I'm midway thru this had to come in for some coffee and to set up me thread!

[LukeTheJoker]

Wow! You are already working hard on it! Awesome!

If I can't make this work, the whole build is gonna depend on Alien tech to get the rear tire spinning...

Carl.

 

[GuitarlCarl]

I've been looking at this for weeks... measure twice cut once, right? Well it should fit according to the micrometer.

Carl.

 

[LukeTheJoker]

Not sure if just clamping it in the seat tube will be enough, it may want to twist?
Maybe to add strength if needed, you could drill through the whole lot and bolt it too...

I like the plans for the underslung apes.

 

[GuitarlCarl]

I've been at it all day! Woohoo.

Pulled the 8 speed cassette off and changed spacers for this vintage Shimano 5 speed setup. I really like the old chrome spoke protector. BUT, uhoh, that chain line is no good, there's two more gears and no more clearance.

yeah that tubing on the BB slid into the seat tube like it was MADE for it... but see the clamp and the bit of seat tube? I think if I cut it off, that should raise the chain line and good inch and a half. Or fab a plate to bolt into the rear drops to stretch it out and drop the frame just a bit. I'm not rushing into either choice, we'll see.

It's the wrong front wheel, I had to put the 20" back on my son's BMX. The 24" still allows room for the goose neck but it doesn't sit right for me. There's that flipped badge too... Like my old Shimano shifters? There's a mod ahead for those bad boys...

I had to hone out the tube at the bottom for the stem to fit but, but it clears the forks just like I wanted. Now, if my bars would just show up! Alien freight shipped them Thursday...

[GuitarlCarl]

Today is done as far as bike builds go... if the past is any indicator, I should be back at it in about a week. Besides, the Alien tech has to cool...

Looking good!

[CRASH]

Sex change! I like it!!

 

[GuitarlCarl]

Lots of odd geometry with a flipped bike
Chain line is wacked just a bit and the dropouts adjustment is the wrong way.
Spent the last couple hours swapping out spacers on my wheel and tweaking the frame some. Dished isn't the right word for the frame, but the frame is built to help the dish of the wheel... flip it and the tweak of the frame fights against the dish of the wheel. Unbend that, and the dropouts end up misaligned. Maybe a left side drive would help, but that's another can of worms... So mild untweaking and rim spacer swaps finally solved my problem, so far. Pulled my front chainring apart and painted the inner ring flat black. It's baking in the oven right now.

Just a little ALiEN tech teaser in the darkness...

Only running on a half dead 9v, roughly half of what it really needs.

Cool stuff here.
I love the bottom bracket idea, but like Luke, I'm wondering if it might twist when you put some weight on it. Either way, it shouldn't be a hard fix if it does pose a problem.

 

[Schwinnspastic]

Like any modification you usually have to modify something else, all part of the fun of customizing ...or is that re engineering ?

[LukeTheJoker]

Oh yeah! Been waiting for the first of the freaky lights to turn up on your build Carl!

Haha, I'm not a great welder but I'm hoping I can pull off a plug weld...
rather than run a bolt thru it or relying on just the seat bolt...

Carl.

 

[The Renaissance Man]

Ah, I didn't realize that it was plug welded! That should take care of things.
