Project plans for the new year? Who is building what?

[recumpence]

Hey Guys,

I wanted to find out what you guys are building this year. Who has a build they have not mentioned yet (or have mentioned, but want to post it here).

I will tell you I am designing and RC drive for my Velokraft VK3. I will be mounting the drive to the frame with CF cloth and epoxy. This will be an ultra-light build with very high efficiency and fit and finish.

So, what are you guys building or planning to build this new year?

[spinningmagnets]

I will be building a boxed-drive with a single reduction belt, 63mm RC motor, and adding hall-sensors. Using a 6-FET with Gwhy's mods (or 9/12-FET?). It will be for a Left-Side-Drive (LSD) connected to the disc brake flange on the rear wheel, similar to Bubbas builds.

Nothing would please me more than someone making and selling hall-kits to add to RC motors. But until someone does, I will make up a few for myself and any others who may be interested (to speed development ES RC-research just ahead of the big fuel-price spike-up this coming summer)...

 

[def215]

well since im fully done my current ebike project. i started another one in this thread: http://endless-sphere.com/forums/viewtopic.php?f=28&t=24029 i thought i try something new.

 

[LI-ghtcycle]

Yep, I've got a very similar build in mind as grinhill's MK II belt drive, and I am just putting together the parts and pieces atm, gonna use a Turnigy 80-100- 130 kV motor and either a hall effect controller, or something along the lines of a CC HV160, which ever is more willing to take the abuse of a low torque set-up hauling around a 150+ lb touring E-Bike.

Here's the link of what I have so far:

That's a Big Dummie Fork, TF Frame, and Crow Cycle's Toughest Steel center stand!

Plans? Well, not any set in stone, but a number of ideas (most of which I've been pondering for at least most of 2010 already).


---A "simple" leaning delta trike. Regular trike kit at the rear, pivot for shock and lean at the front of that kit where it joins the front frame it'll be attached to, which will be the leaning part. Semi-recumbent like CrazyBike2. Chainline will twist in leans, so no pedalling during turns. :lol: Alternately maybe a U-jointed shaft for connecting front and rear halves of drivetrain, since I'd like a motor-driven chainline (as well as perhaps a freewheeling geared hub on the right wheel in back). Parts of this are in the CB2 thread,
http://www.endless-sphere.com/forums/viewtopic.php?p=336930#p336930
with the Delta Tripper thread just for it.
http://www.endless-sphere.com/forums/viewtopic.php?f=2&t=22720&start=0


---A tadpole trike, full-suspension, probably also a leaning trike. Possibly front-wheel motors, rear wheel pedals. This one is already up in the ARTOO thread for concept work.
http://www.endless-sphere.com/forums/viewtopic.php?f=28&t=15214&start=0

---A descendant of CrazyBike2, using as much of what I've learned in the experiments to make it a nicer bike than CB2 is as possible, probably using a hubmotor as the source of middrive instead of powerchair motor (but possibly sticking with that powerchair motor).
http://endless-sphere.com/forums/viewtopic.php?f=3&t=16920&start=0

---Finishing up rebuilidng the VPower pack so it can be used on various bikes, and will be as safe as possible from the failures of such experiments, inside a Kydex box with padding.
http://www.endless-sphere.com/forums/viewtopic.php?p=347865#p347865

---Building up something a bit like The Velcro Eclipse
http://www.endless-sphere.com/forums/viewtopic.php?f=2&t=20595&start=0
for a "normal" commuter and emergency bike, for when everythign else is in pieces or just not working. Most likely it will be based on the Nishiki bike here:
http://www.endless-sphere.com/forums/viewtopic.php?f=2&t=12500&p=327856
and one of the Fusin geared hubmotors.


---Two different power-assisted trailers, one a single-wheel with side-panniers, and the other a conversion of a two-kid trailer to a flatbed. That way I can use either one on any normal bike that isnt' converted, and have assist for cargo or whatever runs.

Timma2500 and myself are teaming up to build a lipo powered alumnium chassis lecky drag bike, we want to push the 10 second barrier Paul wants to take it to
prody Hyaboooosas (which will be a tall order seeing i watched a couple of stock Boosas run high 9's last weekend at the drags)
but as i always say aim high and work your way down or shuld that be aim low then you wont be disappointed when you fail...either way
thats the plan for 2011...will keep you all updated on the progress

Happy almost new year! I'm starting my first electric build in a few days. This is a humble project compared to some of the masterpieces coming out of this forum, but I am excited to start working on it. Its going to be (stop me at any time if I'm braking the laws of phisics) an upright mountain frame with motor and gear-down in the front triangle. Starting with 5500 rpm from a "1000w" SuperKids motor @ 48v to a 4.8 : 1 planetary gear assembly with a 19 tooth #25 drive sprocket. Then from the 19 tooth to a 72 tooth #25 sprocket on a 5/8" jack-shaft (deep breath) over to an adapter and 16 tooth thread on freewheel. Then I'll run from the 16 tooth freewheel to the 48 tooth chainring on my Sick Bike Parts freewheeling crank. I belive (again stop me if I'm embarrassing my self) that this should give me around 100.8 rpm at the crank which is a bit faster than my peddling cadence. One of my main design goals is to produce something that still handles well under human power. Beyond that, I am aiming for a bike that has good low speed off road capabilities, a flat pavement speed approaching 30mph, and the ability to climb the thigh rending hills on my commute. A ride that that stays in one piece and dosen't burst into flames would also be nice. I'm sure I will have a lot of questions for everyone, but I will try to exhaust the threads first, as I know there have been a lot of similer builds here. Everyone have a great new year, and wish me luck I'm going to need it.

Great stuff Matt!!! we should organize a e-vk3s race once you visit Europe with your e-VK3! I have done 9000KM on mine since Jun 2010 - it rocks!

With the heavy winters in last few years, I am going to expand my bikes collection with an e-KMX trike.

My new year resolution is to learn how to build battery packs and more! so you might hear about me more in 2011 asking "stupid" questions!

On this occasion, i would like to pay my tribute to those who brought me into the beautiful world of ebikes: first of all Kamil from Velokraft, Ilia from ebikessf.com and Matt, the God of the mad trikes underworld

 

[comradegerry]

I was hoping to copy somebody elses build up of the RC Greyborg but since I have not seen one started yet on the forum I am willing to learn as I go and blaze a trail. Hals Greyborg frame will get an Astro 3210 with Matt's 2 stage reduction driving a right side crank freewheel, Gates Carbon drive belt to rear wheel with Alfine 11 speed hub, batteries A123 from Cell Man, 48v 18ah if I can squeeze them in. CA, led lights, Lyen controller, built in charger if at all possible even just a 2 amp one, and as many pimp DH parts as can be squeezed onto the bike. Most parts are gathered or on order, build should start March if I get time off from work. The motor and drive has been on my bedroom shelf almost a year already taunting me to do this so it is definately time. I am sure I will be seeking advice aplenty as I fumble my way through this, documenting the setbacks as I go.

I hope it is a great New Year for all on the Sphere.

Hey guys,

As KiM mentioned, he and i are preparing to setup an electric dragbike for quarter mile use to try to take on some big cc road bikes and maybe, just maybe, jag an electric record time (in our voltage class).
Brushless power would be ideal but it looks like a couple of eteks will do the trick to atleast get us started.
It will be fed a healthy diet of lipo and as many amps as the controller /motors will handle without grenading themselves.
Being only 5"7 and 66kg, i will be the one to be hanging on for dear life as it hopefully hurls me down the strip in around 10sec...
Optomistic? Maybe Will it be fun? Hell yeah!!!

Sponsors gratefully accepted :wink: :wink: :wink:


Apart from that, alot more frames will roll out of the workshop this year, stay tuned

p.s. C'mon Matt, we know you must be hiding more projects up your sleeve buddy, give us a hint!!!! :wink:

Hmm, let's see...mostly learning/experimentation projects, but..

'Fixing' two X-360's, pushing them to MD's legal limits, and using them as testbeds for various tech that will culminate in:

100% custom light electric motorcycle
Custom frame, custom hub motor, custom controller, you get the idea.
Think something between an ebike and an electric motorcycle conversion. It was going to be an ebike, but then I found out how simple it is to title a custom motorcycle in MD.
Not sure when this will actually come to fruition, but at the very least, planning should be well along by this time next year and the underlying technology and techniques should be well fleshed out.

Also, possibly adding electric assist to my old Jamis Lightfoot. We'll see how finances work out.

 

[fechter]

I'm trying to get a stable version of my BMS circuit ironed out so we can get some beta test results.
There are always going to be improvements down the road, but at least something that works and is reliable in the mean time. The goal would be to validate the design and eventually go surface mount on most of it to bring the cost down. A version based on the Seiko chip would have most of the desired features, but I still have a few issues with the Seiko setup, so more evaluation is needed.

If I get really energetic, I'll pursue the capacitor coupled balancing scheme a bit more. This will no doubt be a more expensive approach, but possibly worth it to get the heating down and minimize size.

Also in the works, a more full featured version of the Meanwell limiter that has end of charge shutdown (float mode) and a BMS interface, which will eliminate the need for a control circuit on the BMS.

Well, I do not have any huge projects for this winter other than the carbon fiber VK3 (which is a big enough project in itself). However, this winter I am going through my other bikes pretty thoroughly. The yellow trike is being completely reworked (drive, all electricals, brakes, handling updates, etc). The Catrike 700 is getting some basic going over to be more user friendly and efficient, and more powerful. My old reliable recumbent needs a fork repair (the single sided fork is slightly bent). These projects will take the entire winter. Beyond that, I just bought a different van for work and I am configuring that with storage bins and a custom center console as a mobile office. Oh, also, I am building some stupidly insane all metal air cannons to take on this summer's father/son camping trip we do each year up in Michigan with a bunch of guys. The guys setup rifle and shotgun ranges. A few high power air cannons will be really a nice addition to the yearly trip. I have a custom twin pump, lipo powered, 300 PSI compressor I am building for this.

[johnrobholmes]

I am first building a rear end for my full suspension Bullit. The jig is done and I spun down the bearing tubes on the lathe tonight. That build will likely see the 3230 motor first.

After that I want to make my trike a two person unit. With big power behind it (probably the second home for the big motor). It will be mostly used for leisurely rides around, but then when we need to scoot home there will be some "backup" power left

Among this will be my dyno build, and later in the year a parallel gas/ electric hybrid. I also want to build a lightweight ebike that runs the motor through all the gears, although a proper freewheeling crank setup is still the sticky point for it. I think I may use a jackshaft to get around that tough patch.

hello,
I am going to attempt a rc powered trike in the summer stay tuned!

1. Battery box that can fit 8 lipo bricks for the trek 4300.

2. Been thinkin' 'bout chain drive for a while but am considering going DD.

twin 80-100 kona stinky build.

 

[SoSauty]

January 2011, piecing together a Matt Astro3210 bike. For 2011 hope to mount an 8T motor/drive under the BB, get a 2 speed rear end (similiar to chainring shifting) to function, experiment with the GT3mm pitch 15mm wide belt drive, and heatsink the motor.

May use propylene glycol (blue ice) as cheap thermal grease. More likely to wind up with an easy to adaptl $11 dollar auto oil filter heatsink.

The 2 speed chainring shifter holds promise for a LH drive in that it would be mounted upside down and reversed so that it moves/shifts the chain on the non-powered lower side leading to the rear sprocket. Maybe a long shot, but one might shift from the lg. lo-geared sprocket to the sm. hi-geared sprocket with the power on Shifting from hi to lo would take place naturally with the throttle off while braking Think of what this would mean for racing

In order for the Astro3210 to be mounted below the BB and the chainline to have room for the 2 speed, the drive unit needs to be 3/8ths" more narrow (except maybe with the wide 150mm bracket). Easy to machine the FW adapter 1mm more narrow, and use a smaller 14T FW so the chain can clear the motor. Thus the GT3mm belt reduction drive. It's advertised to be 67% stronger than the HTD3mm, though I'd discount that claim. But more significant is the 40%smaller GT pulley's, result in the drive pulley to mesh 8.5 teeth vs the HTD 5mX15mm drive pulley that meshes 5.5teeth. An overall same gear ratio can be achieved using the 14T FW with GT3mmX15mm drive using 22T & 80T, (same as Matt's setup)

Tucson maybe an e-bike new build showcase 8)

 

[Thud]

I just recieved my roll of 5oz carbon fabric...I may build a lil sum'n, sum'n for Tuscon.

 

[gwhy!]

Got some metal, I have been practising my welding ( and I think im ready :? ) got it all drawn up and hopefully going to make a RC motor FS bike frame to accomindate upto 35Ah worth of lipos @44v, config motor options, i.e 1 or 2 motors upto 80mm can dia, also will have a 2 speed shiftable GB for the motor, with just 1 chain to to rear wheel, foot pegs or optional working peddles upto around 20mph but using the motor chain to the rear , 14" ish frame height the frame will have a off road stance. And if it works out it will be one hell of a bike

 

[DeathBlade]

I have a single shaft double turnigy 80-100 build coming up once I find a good right angle box and controller, got 8 dewalt 36v packs on the way.

 

[slowbuild]

I'm still building my firstbuild - finished the motor mount and now onto the battery box and electrics.
Aiming to be testing it by May - given the price of fuel (in the UK I hear of £1.49 a litre of diesel in remote areas)
this no longer appears like a geeky hobby

 

[Jeremy Harris]

I'm working on a competition EV, a race boat powered by a cordless drill. A magazine here has started a competition that will race boats powered by cordless drills around a lake this June: http://www.watercraft-magazine.com/wc_six.html

I'm planning to use some of the stuff I've learned in building efficient electric boat propulsion units to try and see if I can win this - I could certainly use £1200 (around $1800) worth of cordless tools, which is the prize.

[johnrobholmes]

Is the definition of cordless drill pretty loose? Sounds fun!

Unfortunately not, otherwise I'd have stuck a big Colossus motor in a honking great drill replica with a few kWh of LiPo hooked up to it.........

You can use as many cordless tools as you like, but the total market price of them mustn't exceed £400 (around $600) and they have to use their original battery packs. Pretty much puts an effective power limit of around 250 to 300 watts, as that's about what the biggest battery pack can deliver for the time needed to get around the course. I think pack changing will be allowed, but then there's the time penalty involved in swapping packs over.
