5) After rigging up the support bar, I set the actual rack on it to see how it looked:
56385 56384
6) And after a bit of welding...
56386 56387 56389
7) Now for the vertical supports. I decided to do what most professional bicycle racks do, and support mine on the rear axle of the bike. I took some strips of metal and drilled a couple of holes in them to slide over the axle:
56390 56391
8) And connected....
56392
To be continued (still)...

[I]Resistanceisbutyl and four others like this[/I] I'm thinking the support strap will help keep the belt or chain running from the motor nice and tight, too.

please clearly discribe about diy electric bicycle

Lots of progress! I'm looking forward to seeing the motor fastened :)

Thanks all for the replies! =) Resistanceisbutyl: That's the hope, anyway. The vertical supports will keep the rack from sagging, preventing it from touching the top of the rear wheel, and also will keep the chain taut. tiwary chandan: That's pretty much what I'm doing, isn't it? ;) ElectroMaster: Thanks, that post is coming up next! :)

I read about your bike, now I see it. what motor/starter/alternator/generator did you end up choosing?
strantor, September 03, 2011
never mind I saw the earlier blog entry. VW starter,
DerStrom8, September 03, 2011
Haha, yep--that's right. If it turns out it doesn't work, I'll just find a bigger starter motor or a generator. I found lots of videos of bicycles on youtube that use starters, so they should work.

A couple of suggestions (I've got a similar project in "back-burner" mode): 1. Once you get everything situated and built, look into AmeriTyre ([url]http://amerityre.com/[/url]) bicycle tires - they aren't you're typical "solid" flat-free tires; I have a pair on my regular bicycle, and they act and feel -exactly- like an inflated standard tire. IMO, they are well worth the cost. One caveat (not likely an issue with an electric-bike, but I thought I would mention it): You can't do "stunts" with AmeriTyre tires; they don't "deform" like a regular inflated tire and innertube, and will jump off the rim with such extremes (I found this out the hard way - LOL). 2. If the starter motor doesn't work out for you, or you want to try something different - look into the idea/concept of off-the-shelf large-scale R/C brushless DC motors, as well as converting an alternator into a brushless DC motor. If you want to see something wild (and leaves me green with envy - this was what I was trying to do, but I don't have the machining skills this guy has): [url]http://www.recumbents.com/wisil/shumaker/[/url] That's with a fairly small R/C brushless motor, a custom machined belt-drive "gearbox", and a custom-made LiPo (IIRC) battery pack - the power-to-weight ratio of his system is amazing, IMHO (though I doubt it was inexpensive)... Good luck with your bike - I'll be following your progress! :)

Wow, that's quite an impressive build! Thanks for posting! I'm always on the lookout for ways to improve my bike, but at the moment my goal is just to get it put together :D After that, I'll consider getting better parts. I will definitely look into your suggestions, thanks! :)

hey, what type of controller are you going to use? are you making your own?>
DerStrom8, September 27, 2011
I've settled on a simple temporary push-button switch to control a large relay. I think PWM would just be a waste of power.

Hi, are you any motor to drive it?? if yes,pls tell name of it....

[QUOTE=RITESH KAKKAR;bt484]Hi, are you any motor to drive it?? if yes,pls tell name of it....[/QUOTE] Have you read the beginning of the blog yet? This is the 11th entry, so there are 10 more before this one. I suggest you read those entries, too--I go over all the basic parts, including the motor I plan to use.

Hey, the title up there says "Building a homemade 4" diameter spark gap Tesla coil", but then there's all this stuff about an electric bike. I want my money back! I wanted to see gigantic sparks!

I wanted to see gigantic sparks![/QUOTE] Hahaha, yeah, that's part of my other blog on ETO. You can find it [URL="http://www.electro-tech-online.com/blogs/derstrom8/164-building-homemade-sgtc-part-1-transformer.html"][U]here[/U][/URL]. There were a couple of issues I had with my blog, one of them is this title. Unfortunately, it doesn't look like I can change it, so I'm just going to have to stick with that for now. Keep in mind the Tesla coil is still a work in progress.
