Re: Lightweight ME4201 Offroad Build

If nothing else from this project, I learned that there is a reason most bike frames are welded structural tubes. All of the 20 or so water jet cut parts had to have their mating surfaces machined flat and drilled and tapped to match. I spent the better part of a month staying a couple of hours afte...

Lightweight ME4201 Offroad Build

Greetings! The goal of this project was to cram as much power as possible into a reasonably small and light package. At 50 kg or 110 lbs, it's not exactly a mountain bike, but it's still far from a full sized dirt bike. And after working on my 2 wheeled inline skateboard project, I wanted to stay aw...

Re: Custom 2 wheeled electric caster board

It's been a while, but I thought I'd share the final draft of the research paper I made for this project. Probably more information than most would care for, but somebody may be curious! Here's the link to download through my university: http://ideaexchange.uakron.edu/honors_research_projects/352/ J...

It's just regular super glue. All you need is some heat to soften it up. I just threw it in a toaster oven at 350 F, useful trick!

Re: Custom 2 wheeled electric caster board

All I can really say at this point is that it works well in a straight line and seems to be more stable the faster you go. It's probably most similar to riding a bike without holding the handlebars. You just sort of lean and put your weight where you want to go. I'll definitely give a video update w...

Re: Custom 2 wheeled electric caster board

Don't have any plans to sell it, but more than happy to share the designs! There's already quite a bit I would change if I had the chance. Not to mention the fact that all of the aluminum parts required a great deal of filling and sanding in order to fit together properly. Probably would have taken ...

Custom 2 wheeled electric caster board

Well, it’s not really a scooter and definitely not a skateboard but hopefully it will still have a place in this world! This is my mechanical engineering design project partially inspired by boards like the dirt surfer. Specs • Battery: 10S 3P soldered from Samsung INR18560 25R cells (~260 Wh) • ESC...
