Most of you probably don't remember me, even if you were here when I was last around, but I'm back for a minute to post an update to my ongoing "build awesome things from piles of disparate junk" projects, this time to my e-bike.

The whole project is blogged at http://electricle.blogspot.com if you are into walls of text with some nifty photos of work in progress.

Now, keeping in mind this bike made out of all sorts of old things:
several totally different bikes
bedframe corner
skateboard wheel bearings
eyehooks for holding up a swing
scrap plywood
old chair pads
test equipment enclosures
screen door spring
car horn
honda scooter controls and lights
computer scanner transparency adapters
powerchair motor and batteries
rebuilt fried electric scooter controller
bolts and nuts from a zillion things
EKG (ECG) sensitivity knob and control
and probably a lot of other things I can't remember right now, it's kind of amazing it even works:

(They're flash videos, so they're just linked here as they can't be directly embedded in a post)

Build us a custom double unicycle and come back.

(After looking at it for a moment: pretty cool stuff all and all dude.)

Aberwolf! You're alive!!

My pedally ride is nowhere near as cool as yours but is much needed in Osaka since they're my only wheels at the moment. Cool idea though! Make me one for Japan...? Haha.

I don't remember this guy at all, but I do appreciate how all those bugs got worked out!





man screw this guy.




Kidding, that is an awesome project and I love it. That's seriously the type of thing I always wanted to do when I was a kid, without having the faintest idea of how to ACTUALLY do any of it.

Holy crap Amberwolf your bike ROCKS.

This is mine! My dad bought it and then never road it. I moved to the city so he is let me have it.

I call it the Behemoth!

It's a Manhattan Flyer? I'd never heard of them but the bike rides super smooth!

THAT THING IS RAD AS HELL! I love the blinkers.

How many chains did you have to put together to make that system?

Love it. I had a silver one just like it.


Also, ten minutes ago I got my first flat in Chicago. I truly feel like I bike here for real now.

Well, shipping is gonna be 'spensive. :P

You can actually build your own if you like; I gather that in some places in Japan, bikes are reasonably commonly left on trash piles? If so, you could gather many of the parts for nothing. There are also Freecycle.org groups in Japan, so if one is in your area you could probably get anything else you need on there for nothing but the time to go collect them.

Finding a place to do the work might be tougher, but I'd bet there are people to loan you the space, and perhaps even the tools to do it.

The real problem with mine is that since I'm using U1 deep cycle batteries (only ones I have besides even heavier car batteries), the pair of them adds about 46 pounds to the bike, and the motor with gearbox adds at least another 15 pounds, so the whole thing is like 120 pounds without me on it right now. I know I can get 20 pounds off of it by rebuilding the frame from scratch instead of using two smaller bikes kluged together, once I have all the right tubing for it (mostly collected from freecycle lists).

A much lighter version can be done by simply adding an assist to your existing bike with a pair of pancake-style radiator-fan motors (I think the ones I had came from a Nissan or a Toyota, so you can likely find them easily there) with roller skate wheels bolted onto the old fan hubs, to drive the rear wheel by friction. It doesn't work when wet, so you would probably need a rough-surfaced metal roller instead, but here in Phoenix AZ it's dry almost all the time, so it worked fine for me. If the motors are mounted on a stiff plate bolted or clamped to the rear triangle and seatpost, with the drive wheels between the seatpost and tire, it is pretty much out of the way of everything, unlike most of the ones that go over the top of the rear wheel.

Batteries are still an issue, in that to get cheap ones you end up with more weight and less power, but I suspect being much closer to China you could get the LiFePo4 packs by places like PingBattery for a lot cheaper than they are here, and those would have more than 4 times the power density of the lead-acid batteries I have to use.

Batteries are the only thing you probably can't find for free to do the assist (I've gotten lucky because I was patient, but so far I haven't been able to get the battery I really need for free, the LiFePO4 pack (something like a 48V20Ah would be just about perfect for lots of torque and plenty of range, but I'd really like to get several smaller packs, like a bunch of 24V10Ah packs I could split up for light riding/short range stuff, then use more of them for longer trips or ones I expect to haul heavy cargo with).

The motor controller can be built from scratch if you have the electronics skills to do it; there are open-source controllers for RC planes that can be adapted to it if you want fancyness, or there are very simple robotics motor controllers that could be used with just bigger MOSFETs and heatsinks on them. Even just an on/off switch throttle will work, too, if you just need a boost/no boost kind of control. If you have two motors, you even have three levels of power: Both on for full boost, one on for half boost, and none on for pedal-only. If you don't want full boost but find a single motor gets too hot, just alternate which motor you run every few minutes or so.


BTW, is there any kind of a bike theft problem in Japan generally (I know specific areas would be different from each other)? I notice in almost all photos I see of crowded bike parking areas that hardly any of them seem to be locked up in any way. I dont' think anyone will try to steal this one, because it's so ugly and obviously homemade, plus it weighs as much as some thieves. :)

Well, it doesnt' look like a behemoth, after I ended up with my contraption "big" bikes became small in comparison. :P

I've never heard of the MF either, but that doesnt' mean anything--many bike companies make bikes with just a product line painted on them, rather than their brand. I have a "Kensington" that has "Huffy" stamped into the metal on the bottom of the bike, but it looks in design and manufacture more like the Murray bikes I have. All of these particular ones were made in China anyway, probably all at the same factory or set of them, and discarded by various owners to end up eventually with me Two of them are now one of my bike trailers:

http://...blogspot.com/...cs-of-cargo-trailer-smaller.html
http://...blogspot.com/...nearly-makes-full-trip-till.html
http://...blogspot.com/...ink-i-made-trailer-to-carry.html



BTW, the only reason I created the monstrosity in the first post was because I have no other transport, and have to move cargo (freecycled items, groceries, etc) from place to place, sometimes for trips of 30 miles or more. I'd rather not have to ask friends with trucks to move everything for me, so this bike is the main part of the cargo carrier, with a powered flatbed trailer still in design to go with it for big stuff like appliances and whatnot.

http://...blogspot.com/...008/06/lights-camera-action.html

For flat prevention, I HIGHLY recommend Slime-brand stuff. I use both the liners, protection strips that go between the tube and tread part of the tire, and the chunky tubeless-type slime sealant. Between the two of them, I have not had a flat in well over a year, despite the incredible amount of road hazards on our always-under-destruction roads here in Phoenix, as well as the many gravel paths and sections of canal road I ride on, even with a bike weighing many times what a regular one does. It costs little, and they really do honor their warranties, cost-free to you. I had a flat with their slime strip on there due to a really direct hit with a roofing nail, and they sent new versions of the strips to me PLUS new thorn-resistant pre-slimed tubes! If they sent out free stickers to advertise their stuff, I'd put them on the bike, because I really think that much of them. :)


Hmm...new random thought: I wonder if I could charge for ad-space on the bike? I'm sure it attracts enough attention people would see the ads. :-)
PS:

There are three independent chains on there. One is the complete regular drivetrain of a bike, on the right side, with regular derailers and shifters and stuff. The motor has a simple chainline with just a single pair of same-size chainrings on each end, one at the motor, and one where the left pedal would have been on that regular drivetrain. It's tensioned by sliding the motor forward and tightening the bolts (in slots) that hold it on. The pedals have a single nearly-same-size chainring on each end, one on the left pedal, instead of the right side you'd usually expect, and the other one on the same place the motor's rear chainring is, so they both feed into the regular shiftable drivetrain. There's a rear derailer used in the pedal chainline to keep it tensioned, since I have no way of moving the pedals forward to do that, as I do with the motor. Maybe in a future version. :)

The motor goes about the same speed I'd pedal at, so the gear shifting works for it just like it does for me pedalling. :) Needs some improvements, detailed in the blog, but it's very workable even right now.

Some images that show better how it's setup now:

I wish I had something constructive to say and not just holy crap this is awesome and thank you for posting it but darn it, this is awesome and thank you for posting it!

You're welcome! :)

If you can get me and it to Bootycon, anyone that wants to try it out can ride it. :) Certain people if they don't think they can ride it I might let sit in front of me while I pilot it. ;)

I had no idea how to do it either, when I started. I actually knew nothing of repairing or maintaining bikes, despite having ridden for most of my life. Now I could probably be an amateur bike mechanic. :)

Take a look at my bike blog: http://electricle.blogspot.com and go to the oldest posts. I didnt' even know which thingamabob was called what, but I figured it out with lots of intarweb research, eventually!

If you like those blinkers, you should look at this post to see my other lights built out of old scanner parts and some LEDs. They're way better at night, and almost as good in the daytime (maybe better in some situations).

Many of mine don't even make it into sketches, because I forget them before I get time to do it. :(

I've got a bunch of them, including a bike-controller system, that I need someone to code in C for me for the STM32 microcontroller, specifically in the Primer2 devkit. I just don't "get" programming, and have been trying off and on to learn C for a YEAR without any progress.

Math and programming and music notation are three things I really really suck at dealing with.
