Monster (build thread, Lots of pics, Bike Porn included)

Subbed. This looks great. Makes me wanna build my own frame too....

Kudos
 
Progress! I got the chain today. Actually, I got the second half of the chain today. I got a special chain for it, and it ended up being too short. Long bike is loooong. I'm still waiting on the brake cable attachments and a caliper so no brakes yet. (Edit. The y just showed up in the mail) But I got the chain on, and what better way to test the chain line than to ride it? :D

This thing is a beast. No power yet, thats a long ways off still but pedal power was fun. I guessed at the gear ratio when I got parts, but it was a good guess and I think I'll keep this ratio. 36 front, 22 rear. I can pedal the bike for a good ways just fine. Not very fast... but its heavy, slight hills take real effort, and there is zero room for multi gears, so it's a one speed.

It rolls good, but it handles like a jeep on huge tires. If I steer to fast, the front skids, at 5 mph. these Giant tires are s#!t for handling, but then handling was never the point. I don't have to steer around things, I'll roll over them. And I tried that over a few curbs. The bike eats them up.

1st pic is before the chain went on. Second pick is with one of my old racers just to put some scale on this thing. The chain is on, and the front rotor.
That front rotor is a 9 inch, BTW. 230mm looks tiny on this bike.

WOW that thing is a BEAST! You should consider a front hub ALSO just for sheer power! LOL!
 
Can't wait to see it all paint/powdercoated, side panels made, and looking like a stealth bomber but only better!

What size and gauge tube did you use for the headtube?
 
What'd you do about the bottom bracket?

I only ask because I'm thinking about doing something similar.. I figured the headtube was 34mm ID, and am currently looking for a cheap supplier for a 4-5" tube of the right size.

Still not sure about reusing/alternative bottom bracket possibilities though.

Edit:
Read your entire thread over again, and found out what's going on. I'm used to standard bottom brackets, so I couldn't see how it was possible to do threading on the inside. Guess I'll look into alternative cranks.
 
To be honest, I F'd up the bottom bracket. If I do it over again, I plan to use a large blank tube and fit one of those 1 piece to 3 piece conversion kits, so I wouldn't have to worry about threading. I used one on my Boardtrack racer and they work great.

Tru Vantive makes one, Sickbikeparts.com makes another.

I looked up the head tube. Its part number 03-09110 from Aircraft spruce. 1.5" tube, 1.334 ID, .083 wall. hand sanding it made the diameter big enough for the cups.

Thanks for that info. The sickbikeparts one looks promising, and for $15 might just be worth it instead of fabricating your own.

Looking forward to seeing the rest of the build, especially if you're still really going for carbon fiber panels
 
Lol U must be one drunk skunk to need a bike that big!!!!!!! :mrgreen: :mrgreen: :mrgreen: i think u put the shock where the motor should be!!!! But thats just cause im starting to unfrock myself., I love the design and the build otherwise, any reason you didnt put the 5404 middrive??? where u might extract more useful powers? oh yeah and def ditch those tires for some 3.0 knobbies!!!
 
What did the wheelbase end up being, axle nut to axle nut? My racebike is 55" and it handles pretty well, drives like a tank at sub-5 mph but it's stable all the way to 85.

How'd you decide where to place the rear shock so that the swingarm travel would follow the line of the shock's travel?

I was wandering this too for my bike, than i thought that swing arm has to move in circle, than i thought if i would lift swing arm to the frame, the point where swing arm shock mounts meet the frame would be the point for top mount for shock. Would that be right???
 
For true linier movement, you want the shock eyes to both be the same distance from the pivot point.

If you offset one end of the shock closer or further from the pivot point, you will have more suspension travel, but you'll lose the linier motion. Thats what I ended up doing. Not realy the ideal but it gave me the travel I wanted and the shock position I needed.

Yep. Redder than a Red Sportscar. Black side panels are just templates for now. real ones will come last.

:shock:
Nice work mate!! Can't believe you just put that steel frame on the car like that. My jaw almost dropped. Let's hope some paint wasn't going to get scratched.
You ever think about selling frames? This looks like a rugged and low maintenance kind of frame most people here are looking for (including me) . Call it, raw performance 8) . What is the space inside the frame and how many of what type of battery's do you plan to fit in the frame?
When are you going to mount the 5404 to this beast?
 
I'd love to sell a few! But at 27lbs, not many people would want one. Battery box is 100m X 120mm X I forget at the moment. not at home to measure... long enough for 3 cells and the wire between each. It will hold a total of Twelve 6S 5Ah packs. Designed for 100 volts, 15Ah, but I'll be wiring it up for 66 volts at 20Ah untill I work out all the bugs.

No worries about the paint either, its sitting on those black foam mats. The motor got mounted up last night near midnight, along with the fork and front wheel. And I spent the last 3 days making the 13 pannels that fill in the holes in the frame. Just 1 piece left to make, then I can finnish assembly. If I get home in time tonight, I hope to get the brakes, pedles, and chain on it.

This Monster needs a name. I mean it is A monster, but it's not The monster. Other people have monster bikes as well. It needs it's own name. I mentioned to the GF this morning that I needed a name for my big red monster. She looked at me like I was an idiot, compleatly bypassed my inuindo, and started singing "Ataaaaaack of the killer tomaaaaatos..."
 
At 27lbs, I would still buy that frame at the right price. It's almost EXACTLY as what I want to do with my bike.. have 26 4s packs on the way to me for this build (20 of them will be going into this bike) for a 20s20ah build. It looks really good and I really can't wait to see this thing completed and running on electric power. It's been a great inspiration, and I really appreciate you sharing the ups and downs so I can be ready when I do my own build.
 
Yeah weight isn't an issue for me either. Like loveya kind said, if the price is right you can look forward to getting me as a customer as well. :mrgreen: . It is hard to find a bike that can stay stable at speed. My bike does quite a lot of flexing and anything over 40 is getting into some scary territory for me. Heck the regular bikes we buy at bike shops aren't even built for this kind of stuff.
If it can fit 20 4S hardcases packs for 20S 4P of turnigy hard case packs that would be a cool bonus as well. 8) . Just tell me when to start sellin my current bike.

Don't be afraid to show us some pics of your progress mate. I'm dying to see what this bike will look like with that 5404 in it. Is it rolling yet?
