ATV tire Bike Build (Mid Drive Hub Motor)

[johndjmix]

Got a lot done! Took it for a quick ride with pedal power....waiting on kelly to replace a faulty controller (And I should add Kellys customer support is AWESOME!). Here is my progress....Last pic is right before the first ride. Cool thing is, I fit six 22-AH Lead acid batteries in the frame. I just wish i had another 1/8" in there of width because its a TIGHT fit....but the lead is only temporary and this is just a prototype, so no biggie.

Nice

 

[pkirkll]

Starting to remind me of the old Honda Trail 70...... no insult intended--they are good little bikes.

And you have an inbuilt Cheese Grater (rear guard/suspension mount with holes) !!! Perfect for BBQ emergencies!

Just kidding, man... again, thrilled to see what a well equipped shop and 'sperienced builder can do... crying small tears cos of the SLA but meh, I understand where you are coming from... Considered thunderskies? 'spensive I know, but as robust as Lead acid, charges with same chargers or better, and at least 1/3 the weight... and well tried and tested in larger EVs now...

pkirkll: Funny you should say that, I have 2 CT70's myself. One is a '69, still running on what I beleave was the origonal motor. Crazy, its older than me and still going! My other is a '94, which was the last year they made them. 12V system, CDI ignition, and mines in near mint condition...paint and all. No way im getting rid of that thing!

Ever think about doing an electric conversion to a CT70? Dude, you got me thinking now. Wouldnt be hard at all....mount the motor and batts and your done. Not sure how you could attach pedals so you could make it an "electric bicycle" though, but with some thinking it could definitely be done.

winkinatcha: Yea, its getting heavy so im trying to save some weight with the holes....As for batteries, those thunders are way too expensive but i was thinking of these:

They seem to be the exact size of my 22's and made with a LiFeMnPO4 chemistry. Light suckers, 6lbs each, so my whole pack would be 36lbs.

Finished the cockpit displays tonight. Temp gauge is for the motor temp. Ignore the voltage reading, using a temp old batts for supply. Then you have 2 switchs for who knows what. Then 5 small holes, each will hold a LED, 2 of which are for the controller status/error lights. Then the key, and to the right of the key a USB port to charge phones. Humm, what did i miss in there.

 

[pkirkll]

I took a quick look at the battery,,not too shabby! Stil less weight than SLA probably 3 lbs...huh

Yeah if you ever get tired of one of those CT's let me know!!!!! :wink:

Slap yourself for still missing 2 misspellings while you were editing.

Regarding spending, I don't see nearly the amount of useless spending here compared to discussed on pedal bike forums. Many of us stay pretty frugal, but even for the guys with the more costly builds it's a pretty cheap hobby....and one that can actually pay for itself in economic terms. In overall terms, building your own machine for basic transportation or just for fun is priceless, so slap yourself again. :lol:

To temporarily continue the OT (before recommending that we drop it, and let the OP decide if responses to the rude noob's first post are worth it):

I take it you haven't looked around very much yet.

There are quite a few builds specifically intended as low or zero budget builds; some like most of mine are typically intended to specifically *exclude* any new parts, only using recycled bits either repurposed from other things no one else wanted anymore, or donated (or bought very cheaply) from someone else's junkpiles. They are also all for the purpose of transportation (myself, dogs, cargo). Although I certainly do like to show them off, they definitely aren't "better" than anything else in *any* category I can imagine.

Numberonebikeslover's main build is another recycled/repurposed inventive build, specifically to be extremely-low-cost (even in *his* economy!), and as his transportation, as well as inspiration to others that they can do the same thing if they wish.

 

[pkirkll]

Whoa y'all ,,,that was a joke,,,hard to get context in the written word,,,,,,sorry for the offense, none intended...

 

[amberwolf]

No offense taken; I just know that lots of people don't look around the boards much, and miss a lot of things.

I think it comes down to this. You want what you want. You make it the way you want. Maybe you want big tires, maybe you want 150V pack. By building it yourself its your creation.

That said, ive had several customers pay us thousands on custom builds of our small vehicles. Really there is nothing like them. The bike is a prototype, which is why the frame is steel and using lead acid. If the prototype pans out it will be fully aluminum. In the past we have built 3-6 prototypes of a machine before we get perfection.

I have a lot of respect for people that can create, no matter if its an artist painting, a programer writing code, or a contractor building a house. The people who can create (And a lot of the guys on here seem like that type, are really the people that move the world forward. Could you imagine if we just accepted everything as is and didnt make new designs?!

ANYWAYS! Back to the bike. New kelly controller should be here Tuesday, and Kelly's support has been amazing. Ill let you guys know how it goes when it gets here.

Lets keep this thread on-topic from here on!

Took it out for the first real ride tonight. Top speed wound up being right where i wanted it, about 35 mph. Power was amazing, but, as i figured, with such a large motor and ATV tires my watt hours will suffer. I was seeing about 78 wh/mi, but I was ridding hard....a lot of wide open riding

[etard]

Your bike is awesome man! If you could post a vid of it or some pictures of it in action, it would be much appreciated. Thumbs UP!!

 

[johndjmix]

Had some chain tension issues, so had to re-design a few parts. Blew it all out tonight. Now the chain adjusts motorcycle style where the rear wheel sits in slots and can slide back and forth. The sprocket i used on the tensioner is now in a perminant spot, used as a idler to keep chain in a position perpendicular to the swingarm pivot.

Seems to work good, but lost a few set screws on the motor tonight, so will get them tommorow. Hopfully Thursday ill get some video in action! Monday it MUST go out to paint so it will be done!
