So, who's hiding a project?

[recumpence]

Alright, Alright, Alright...........

It seems to me there are precious few new builds going on right now (openly) and a few people seem to be low on number of posts. So, it seems to me there are more than a few custom builds going on that are in the "Hush-Hush" catagory.

So, come-on, who has a wild build in the works? You do not have to give away what you are doing, just let us know you are working on something! :wink:

Gee i hope your right . this place seemed alive when i first got here and as of late ive been wondering if i stank the place up or something cuz it kinda died a bit.

 

[def215]

i dont know :wink:

so far my next project is only on paper after finishing up my first e-bike build. when i actually have something tangible, ill start to post....lol

That was my original theory.

hey if i shower and wash up the wife wants some action and well shes my wife . remember the tv show married with children ? Al bundy was a genius.
hopefully i dont stink to bad :wink:

I dont think ive said it yet so i will now, your reduction units are something ive been coveting. ill be giving you a tap as soon as the junk ive been playing with gives up the ghost. just gotta get a better handle on my finall setup (motor rpm, top speed all that) and you can expect a msg

Yes, I do. I am throwing caution to the wind and building a $10,000 insane project bike.

But, I know others must have stuff being built right now as well.

haha... and hes fabbing up a reduction unit thats out of this world too...lol

I'll leak a bit on an idea I had with the full susp. bike builds... it might make regen..."more possible" for non-hub drives:

Of course you would have the expense of building the damn thing...but it could provide some regenerative energy for the non-hub full suspension bikes if done proper, and add to regen braking for hub full or partial susp. bikes. I would love to make this project happen during my engineering baccalaureate degree!

Snow..... ( Hibernation, time to ponder what to build next.. i hate winter )

No, no, no. Winter is the time to build not ponder...........

Summer is for RIDING!

I Wish......
But I already have my butt overloaded with "little" projects (bad economy is going to make me king of the "MICRO" builds....hopefully I can show what can be done with a shoestring budget. (& a bag full o tools.)

Besides, No one can out power Recumpence..... He will putt twin motors on a roller blade! (his electric shaver is 6500watts!) his alarm clock runs on 440 3 phase. His tooth brush is cnc controlled.

I post too much and build too little, but...

5 months of unemployment put a damper on play-money spending. Moved from Utah to Kansas to acquire a good job ("good" in the sense that galley-slaves get an extra helping of gruel and will never be laid off). The move put $3000 on my credit card,...but enough with the excuses!

The DIY longtail thread inspired me. I like 2-wheels with full suspension and a front disc brake, so the plan is to take a 26" hardtail MTB and add a rear suspension arm. I have acquired a used double-disc-brake hard-tail MTB. It will be a test-mule for several experiments. I'll use the rear V-brake on the suspension-arm and use the rear disc wheel on a different bike for left-side-drive experiments (the wife doesn't know yet that her bike will be getting a left-side-drive).

I have very cheaply acquired a Sturmey-Archer hub, and a second S-A laced to a wheel for experiments. Plan to try the hub as a 3-speed transmission at some point, perhaps at 750W.

Axel hasn't published his 3-phase DIY motor yet, but his single-phase tutorial was impressive. I plan to make and try one of his 3-ph motors as a stoke-monkey. My post-holiday trash scrounging netted a road bike and a largish aluminum BMX (also 4 cheap MTB's that I made into two working MTBs that I gave away). I want an RC friction-drive for the road bike, but thats probably a couple years away. I want a SRAM Dual-Drive but I won't order one until after I have two splined ENO's clutched in my greasy hands.

I have one (only Luke knows what that is though :: wink ::) Hint: a range of 1/4 mile only......
but i have to finish the one im working on first and clear up a few 'lil jobs' in between that haha...

Me be busy busy buy all this year...

I'm slowly working on a JD TidalForce project. Nothing crazy, just an Ebikekit 9C rear, but you know how those go. Ordered some spokes today to hopefully get it laced into a wheel, then I just have to do the mods to the frame and the disc caliper for the rear disc to fit and then determine what batteries I want to use. Hopefully be ready for a ride come spring. I will probably start a thread on it this week sometime when the spokes come in. Guess I should have started a thread before I ordered spokes, there were probably a few people on here that could have offered me some advice. :wink: Oh well.

Oops, non-hub thread. Sorry.

 

[mud2005]

well I change my mind about my next build on a weekly/daily basis, but I'm thinking about building a bike that coasts silently. It will involve a freecoaster hub and a one-way bearing. also I want the motor to be covered so I can actually ride in this crappy weather.
Lets see if I can build it before I change my mind.

 

[voicecoils]

I have two 'hidden' builds going that are dragging on due to no free time.

The finished bikes will be detailed on E-S but I reckon I'm the one looking forward to them most!


EDIT: just realized this is the 'non-frock' section, damn active topics browsing

@dequinox: That assembly looks vaguely like something I am considering for my "hidden project".

It's not really hidden, just that I have not got far enough in the pondering stage to start a build thread yet.

I am currently working with Google SketchUp and the collection of bike parts and other stuff I have right now, to work out the very basic idea of the front-wheel-motor-drive / rear-wheel-pedal-drive recumbent tadpole cargo trike that will replace CrazyBike2 for cargo use, letting me lighten it up considerably and turn it into a pedalable commuter bike.

This is the new build thread for the trike, which currently has little beyond an opening post with a basic description of the concept.

(yeah, that's my idea of "basic" :lol: )

I accept that as a challenge.

Hell yes! If you manage to get it done, it will be one of those internet legends that gets passed around by email to the world. Projects like what you're planning are a huge help to the EV revolution, and shifting peoples perceptions of EV's as being lame slugs.

 

[liveforphysics]

I'm privately working on my ES contest motor build. Hopefully it will be good for 75kw for a few second bursts, and 20+kw continously.

It will be powering my 100mph-or-bust bike build.

I'm going to get a fat stack of those prismatic A123 cells from cell_man, maybe 2P40S, and hit the motor I build with everything I can throw at it on a tiny lightweight areodynamic bicycle frame with extreme ducted airflow going through the motor, and just find out what happens. Motor burn? Controller burn? Luke crash and burn? Tires explode? Frame/fork breaks? I don't know what will go wrong first when I go for broke, but I better reach 100mph before it happens.

I will have my full motocross gear on over the outside of my 1 piece superbike kevlar/carbon/leather/titanium suit and my favorite bang'd up lucky Shoei, so I will be feeling relaxed and calm through the wreck if/when it happens.

So Summer for riding aye. Well the forecast for tomorrow is 43C so riding I don't think so.

But I do have a confession I was expecting to do build a round the ASTRO 3220 engine and have just ordered and the guy how had promised a geared 500W for my 700C has finally delivered. Now I guess I got two builds on the go. The hub build is a relatively straight forward conventional domestic travel solution but what to wrap around the 3220?

I had some ideas of a tadpole design or a two wheel recumbent. Would need suspension for a good tadpole design. Also has any one used the multi V belt as a drive solution for a 3220?

 

[amberwolf]

extreme ducted airflow going through the motor, and just find out what happens.

Just for efficiency's sake, make that ducting like a turbofan engine. Heck it'd be good for look's sake, too. Maybe it'll be a even a really cool sound effect as it spins up.

Yep, I'm thinking one of these 5" ducted fans:

http://www.hobbycity.com/hobbycity/store/uh_viewItem.asp?idProduct=4235&Product_Name=EDF_Ducted_Fan_Unit_7Blade_5inch_127mm

And I've all ready got this motor sitting on the shelf at home to power it:

http://www.hobbycity.com/hobbycity/store/uh_viewItem.asp?idProduct=4937

It would be nothing to dump a 1-2kw into the ducted fan and generate a few thousand CFM of high velocity forced air moving through the motor. lol, ducted correctly, the cooling system would give me around 5lbs of thrust alone, and be able to carry away 10kw of waste heat from the motor effortlessly. lol

 

[liveforphysics]

Actually, working rough numbers, a 5" ducted fan like that could be in the 50kw continous cooling range. lol I think I could safely go a little smaller, but that wouldn't be my style.


These 5" ducted fans running at a few KW make leaf blowers seem like toys.

 

[amberwolf]

Yeah, it'll be pretty funny--the cooling system alone will probably make your bike go faster than some of the regular bikes around here. :lol:
