1982 MB-5 30kW peak 230 lbs Complete new VIDEO! 82mph

I gave in. I want reliable controllers with a warranty I decided. After all, this is not only a hobby bike, this is a commuting bike that needs to be practical. I got dual kelly kbl96251 controllers. Good for 125A phase amps continuous each. I think they will allow me to do 25kW peak comfortably.. maybe even more if the motor is happy.

$900 shipped. Last EV purchase for at least a few months.
 
After many late nights, I finally got the Kelly's behaving. ALLWAYSSSSSSS make SURE: YOUR CA MUST INITIATE BEFORE KELLY! This one stumped me for an hour. The Kelly can be programmed up to 2 seconds delay on startup. I had a switch that turned on CA and kelly at the same time... so the CA throttle output was still low when the kelly checked the throttle lines for crazy throttles.

I went 55mph today. Still taking it easy at around 18kW. twitchy throttle.. replacing with magura. pics and shitty video in a little bit. better video next time.
 
82Wh/mile today. average 20mph.. 55mph peak. mostly launching in parking lots (avoiding roads). This is a really bad video, and this is a really questionable music choice. More go pro after I get this thing charged.. it's a bit of work to charge it at the moment.

I went REAL fast today. more on that after I have video. 160A phase, ca limited 110A to each kelly.. what a blast. switched the tire rotation around cause I had it put on backwards.

Poor John in CR has been catching hell for his "Hand Thermometer", And now this. ?
I went REAL fast today

:roll: :roll:

Looks like we needs some serious calcalatin to happen round hyar. :wink: :lol: :lol:
 
Lol don't worry I won't disappoint. My speed sense wire for some reasn screws up one of my controllers. maybe need a resistor in line with it or something. Go pro tomorrow if the weather is good and I can figure out a good way to mount it
 
WoW really nice work man!! Been watching this build and i must say , nicely done, I hope you enjoy it!! :mrgreen: now get out there and RIDE!
 
It's a lot of fun. glad you like it. To be quite honest I get quite a lot of looks on it. Could be a bunch of different things.. the big guy on a small bike, freaky bright magicshine running during the day, small rear wheel, or 0-50mph when you weren't expecting it. I look forward to dragging a gasser.

only 2 cycles so far... waiting for my "faster" charging solution. 500W chinese charger from mwkeefer. THe nice thing about it is that it will fit underneath my seat and be stealthy. inexpensive solution as well.

I want to take it up to Northern LP Michigan around the lake this month.. :)

I first posted this thread on July 4th, 2012. Almost 1 year ago. Lots of iffy decisions.. time in the shop... etc. Glad it turned out the way it did. Let's just pray it is more reliable than my cromotor 29er
 
yeah 29ers suck!! You really need two or three meanwell s-350 chargers. like kingfish. and me and all my e-friends in this city. Yeah its a dumb charger, but if you bms or just watch your cells your fine. you can usually get away with three on a single 120v 15a circuit. thats a groovy 1200w of charging..... :mrgreen: but yeah mwkeefer was one of the early pioneers in the meanwell power supply mod.....
 
For the beach you need a backpack full solar modules to charge your bike. Green geeks are in and solar charging in public will get you intros with lots of chicks. Hiding in some corner connected to a wall socket will leave you a lonely egeek. Charge rate is largely irrelevant. You have to wait no matter what, so make the best of you charge times. If someone asks how long it takes to charge, just say it depends on the charger, and the batteries you have can be charged in 6 minutes, but you're in no hurry because you get to meet more nice people like her. 8)
 
so basically fold out the panels, the lay out series of panel colored beach blankets, start frocking, and then by the time I'm done frocking all the women I will have enough juice to go down the beach a little ways for some more solar fun
 
Running good. tried 27kW.. very fast.. need to be very alert! also need to dial in throttle feedback at that level! MOstly less than 20kW usage though. Plate soon.. need a jacket and gloves pretty badly. hide a minor slide at low speed. I'm okay. Need to get used to riding these things. CAn do class to fullfill the skills/knowledge test... but don't know if I have enough range to complete that course in the 6 hour time frame.

ROFL

That would big a big frocking blanket
 
some day it will make sense. right now I rather buy more batteries, which is actually current plan. I want to make a range extender pack of 20S lipo. Right now (based on one visual calculation on flat country roads) it's 77Wh/mile at 40 mph and 100Wh/mile at 50mph. I have 2400Wh usable. Could look into a combination of aero and the economy lipo pack. I think 3.5kWh is about minimum for this build. The electric motorsport bike I believe is 3.3kWh.

I envision having a second contactor, and wiring it such that they can never both be engaged. common grounds. separate bmses. CA V3 has the 2nd battery mode so that would come in handy.

In case anyone wonders why I didn't start with a bigger pack, it's because I got a very very good deal on this pack I could not pass up. AT this point, the only change I can practically make is taking it up to 32S12P from 28S12P which doesn't make too much sense. It'd be almost impossible to break it in half even if I wanted to.

Last news is I had my 150 pound friend ride this thing around.. it looked ridiculous. IT is really frocking fast.
 
this is probably a bit extreme, but if you haven't checked out the vetter fairings - its probably the most well known/tested/proven. heres a link to a zero with one:

i admit they look pretty funny (more so the zero in my opinion) but the energy savings/reduced drag is enormous with something like this (especially at speeds above 30)
 
definitely hand made =) i was just showing those for the proven concept. heres a link to a bunch of fairing construction/techniques:

http://www.recumbents.com/wisil/whatsup.htm#Fairing

and heres one easy way (making one out of coroplast):

http://www.recumbents.com/wisil/tailbox/barracudatailbox.htm

i like the look of this one as far as recumbents go

it's neat. Yeah the vetters are in the ballpark of $0-2000

"Three piece kit cost is $1750 plus tax if any plus shipping."

Is it true that the biggest drag is actually on your back? kinda like a semi truck? I noticed a lot of trucks now have a fairing on the rear door at folds out.. pretty neat. All we need is elon musk to offer a full air suspenion semi.
 
the rear is more important (think of the wind closing nearly completely behind you - relatively no turbulant air) but having the front almost completely open like the picture above is obviously not very aero - lol. a combination of a front fairing with a tail will definitely produce great results
 
The problem is making a tail fairing that seamlessly attaches to a traditional position motorcyclist. You have to sit upright or reclined, as you see Terry Hershner in his Zero above (upright).

Read up on blowing your own fairings on the recumbent site above.

Or, this site has a ton of motorcycle fairings for reasonable prices.

Need to get my hands on this fairing! this is a highly modified mb5.. probably done in the early 90s.

Broke 500 miles today. By the way.. Consumption:

Taking it easy, 40-45mph cruising: 70-80Wh/mile.
Pretty agressive.. some 70mph stretches.. lots of 30kW pulls: 95-105Wh/mile

I make sure after aggressive runs of 2kWh that I cool the stator down to 100C so as to not damage magnets. Just put it on a stand.. keep it spinning.. use some mist. Just like Farfle does. I haven't had time to really address cooling, but it seems that as long as the motor is spinning fast at speed that the temperature is pretty safe. Somethign more substantial is planned for future. Probably during next rebuild when I powdercoat the whole chassis. Having the V3 temp display is really handy, and I'm developing a feel for this motor's thermal behaviors.

Lastly, I'm considering a 10Ah 24S turnigy booster pack in parallel with this one. 22 miles guarunteed range at these speeds is substantial, but only really if I have a bigger charger.. like the dual 1kW meanwells I'm planning. the 24S lipo will give me another 8 miles. I could probably fit in 15Ah if I wanted to but that's heavy. Almost rather wait and build myself a big 6kWh 18650 pack some day.

How much is a non-running MB5 worth? Someone local has a couple of these for sale, and I am considering it. He wants $800-1000ea, which I think is a bit high (not running). Of course I want it not running for an EV conversion.

Also, I thought I read in this thread that it's 112lbs stock? I'm reading a spec sheet that says 174lbs dry. If it is indeed 174, then I probably don't want it as my KE100 is about that weight stock.
 
no no.. I thinkt hat was for the magnum. mb5 is 174-185 dry depending on features..

$500 is what I'd pay for non running.. post the links and images to the honda mb5 facebook group and they'll give you an opinion. Good to see another potential candidate for conversion!

also ask "Parts - Perk L.L.C." <parts@perkllc.com> for anything you need. He helped me out a great deal in making this project possible. I paid almost nothing for the frame cause I went and pulled it out of his barn. He actually made it to TTXGP this past weekend and saw the finished product.. pretty cool!
