I ... drove it at 55mph without the body, just the frame. The wheels would lift off the ground at any point you turned even remotely sharp at any speed over 25mph. How did I figure it out? I spent a year building this. Testing each new idea.. I put 100 miles on it testing it. The larger portion prior to deciding on a final design.
Going down a road straight, and doing as sharp of S curves as it can handle from edge of road to edge of road. If you read this thread people very much experienced with KMX frames also said the same as my anecdotle evidence. The whole body twists with just the frame.
I drove SCCA for about 2 or 3 years. I've had no issue driving it with or without the body. The issue is physics.. you have more or less a lever on the front. It causes leverage, causing the frame to twist in the longer part of the frame. Again, you can actually watch the wheel and frame flex if you take it into a parking lot and push it as hard as you can without tipping it.
You have a 150lb Plus rider you seem to be forgetting about. Sitting dead center offsetting the 25lbs of weight in the rear. The trike TOTAL weights under 70lbs... There is about 15lbs of batteries. My added weight for the body was nil. Maybe 5lbs. in the shell, and another 3lbs in the deck plate. It is super balanced. Before the body was finished and I retested it all, I was absolutely sure I would have to use a steering arm. That eliminated that. Stopped it from being squirrely. Don't know why it is even a question. Race car driver has been zipping around on it since I posted the newest pics. Says it handles amazing..
Other people can't hear wind noise. And yes I had it up to 60 about 10 times in the span of 30 mins on the last test drive. Country roads with turns, pot holes, uneven roads, etc.
Yes if my chain breaks on my bike, I just keep going. Same with this trike. Mid drives are noise from turn of the throttle on. I don't like to draw attention when I'm riding. I think a mid drive motor with a chain drive would absolutely get more attention from people hearing it.
Your logic is faulty, you obviously didn't read any of the thread, or the details of the trike. I'm 5'9" 150lbs and can hold it off the ground at chest level with no problems. Again, weight is balanced, and was important. Anyways.. just more and more a waste of time repeating things I've already covered, but time and time again in comes someone that read a few posts and jumped in to opine. Fabulous.. I'm sure lots of people reading are really learning new things from the lame replies. Again.. start at the beginning. I used this as an idea bouncing board and spent a good deal of time explaining things...
