I've been converting a used up 1993 Hurricane to an electric bike and I did the first rear wheel power test over the weekend. I rigged up a rear brake this evening and took it out (too dark for video, will shoot some soon). This motor puts out 100 ft/lb of torque and with 1:4 gearing, will easily push the bike over 120. For the short time I had it out this evening, it was a blast to ride.

You'll notice the chain noise in the video is loud. I was worried about that at first but found later that my bike lift was magnifying the sound a lot. It's also machine chain vs. o-ring and an industrial sprocket which has no wear. Anyway, hope you enjoy and when I get an on-the-street video, I will post it.

I think you can just notice the noise more because there's no engine/exhaust noise on the background... Curious to see some new vids on this conversion

 

Looks awesome ... more details of how ya did the conversion and what your using as power cells and where your going to stash them would make for and interesting read!

Cant wait to see the vid when yet get out on the road!

 

Shakey - you're right. I failed to mention that I've been documenting the conversion on my site. Details about the conversion are at www.dalecoyner.com

I shot a little "on the road" video this evening and after I edit it, I'll be sure to post it.

 

Wow! Just had a look at the site! Thats some amazing stuff you've done!

What's the controller you're using?

 

That is a Curtis 1238-7501. It's capable of running up to 108v and handling up to 550 amps, so once I get some serious batteries into this beast, it would make a very fun track day bike.

 

i love this build..way to think out side the box...

 

Pretty awesome, man. How many batteries could you cram into the chassis? In terms of how much voltage and amperage?

 

So are you thinking 18 batteries, which give 108 volts (paralelled pairs) ... with the batteries described on your site, that should give you approx 396A/h??? Or is my schoolboy physics in need of brush up?

Keep up the good work matey! .... Did ya get any more video edited yet?

regards,

shakey

 

Thanks, it's been a fun project. I am currently planning a 72v system with 100 amp-hour lithium batteries. I have some tiny little sealed lead acid bats in there now, just to let me run it a few miles at a time for testing. But with the space created by that big motor, I am counting on being able to get 22 to 24 cells into that space.

If I gear it for speed, that motor could take me to 120+ -- it's the same motor used on a lot of electric race bikes. If I gear it for optimal distance, 7.2 kw should get me about 60 to 70 miles on a charge.
