I just got back from a 30 minute ride. It's cooler out tonight and the motor stayed within a touchable temperature. We had a lot of rain today and the field next to me was nice and muddy so I had to give it a try. I kicked the bike into first and hit it, the back end was fish tailing as it...

I cant be positive yet that heat will or wont be an issue on the planetary if I put dynamat on it. I do know that the planetary did not get warm while I was running it so I would assume it's not really producing enough heat to cause an issue, but time would only tell if it would heat up over a...

Thanks Bubba, and Joe the flange I believe was meant as something to hold a bash guard or something of that sort.

On my first test run I went around the block quite a few times just going slow at first. Speed in first gear tops out around 13-14mph as I shifted up speed continued to gain. I made it up to 30mph and then decided to slow down and check the motor... I felt the motor and it was pretty hot so I...

Very cool, I may have to pick your brain a little as I dive a little deeper into it. How was the arduino? I currently only have experience in Pbasic, and am not sure I'd be able to take on a new langauge and have it all ready for presentation in 2 weeks.

I finally got the battery mounts finished up this weekend and did some wiring. On Saturday I made my first trip on the bike and was rather happy with the results. It had good pickup and was still pulling past 30mph. The one thing I have to be careful of though is the current pull of the...

Agreed, sport became art in that situation. It brought back old school feelings of growing up in the 80s during the bmx/freestyle boom, the only thing that mattered at the time was my Raliegh Rampar R10 and "The Jumps" as we called them.

The build continues to move on... Tuesday I cut the threaded side of a rear bike hub off for the freewheel and then welded .5in to 1in shaft collars inside of the hub. I attached that to my planetary gear box and then screwed my freewheel on to that. I then made the chain to length and began...

The planetary gear box was purchased From Andy Mark a robot specialty store from Indiana which happens to be close to me. http://andymark.biz/am-0270.html . I didn't get all of the work done that I wanted to due to having a coil spring break on my focus so most of the day yesterday I was...

Ok so I'm back on the build again and the Haro X3 is now taking shape. I've finished building the bike, every component on the bike should be quite durable. I'm using Shimano Saint 8in rotors/calipers, hubs, shifters, levers and deraileur. The motor I decided on going with is the hyperion...

I've also been running the planetary thought through my head for some time. I purchased a 13.5:1 planetary from these guys http://andymark.biz/am-0270.html. It's of rather good quality and should be on my bike within a week or so. I'll be running a hyperion 5025 motor on this in a cyclone...

I would think one is really better off to run a rc designed controller simply because of the volt amp differences. Though I know a crystalite controller can be modded to handle some more power than stock it seems like they have a max of 40 amps at 72Volts and that controller sells for 229.99 on...

I found a pretty cool site that might help in the reduction from motor to sprocket. http://andymark.biz/amshifters.html

This may help a bit as far as what I was thinking about.

I was searching for some 3d software the other day and stumbled upon this. It may be one of the easiest 3d creation tools I've ever used http://sketchup.google.com/
