"Jack is profoundly physically disabled; the tumtumcar has been the most exciting thing to happen in Jack's life in quite a long time". Phillip J.C. North Carolina USA.

The idea is good but even the narrator questions how many wheels mr adams will be able to keep on the ground and he doesn't look like he is going 20 mph. I like it but it looks very unstable, and awkward to pedal, it could do with some kind of dampening and a better position for the pedals as mr adams looks very uncomfortable trying to pedal it. I pointed to the quadrix cos it looks very stable. the tum tum just looks way too unstable, potential avoidable injuries waiting to happen.

Flitsies, your comments indicate you represent Quadrix in some way, rest assured we are in no way competing them. Your original observation was clarified with numerical logic. If you are in anyway involved in engineering, you are aware pedal drive needs clearance for the crank, please do not compare a pedal driven thing with electric only drive. We are world's only makers of tribrid vehicles, our team knows what is best, comfortable and safe to incorporate in design.

You tube this and you will see the difference ok it is electric but look how much more stable this looks. Présentation du Quadrix Watt'S

I just wonder what would have happened had mr adams leaned over to the wrong side as he cornered his tum tum, I suspect the thing would have gone over. In fact judging by the looks of this thing, had he just held onto the bars not moving tuned them to one side and leaned over the opposite way he would be flat on his face. It just looks very unstable lulling the user into a false sense of security due to it having 4 wheels, it has no suspicion or dampers to absorb movement either.

Hi Flitsies: 1: 1-Seat tumtumcar (in this video) has a 40 inch Track Width, 16" (height of rider bottom centered), so, the Tip Over Point (@20mph max speed) is located at 22.80 inches. Well beyond the safe stability limit. 2: Video played may be little deceptive in "Aspect Ratio" set for individual Monitor viewed upon.

John Adams is 40 and physically impaired.

That thing looks dangerous, high centre of gravity will tip over easy, it needs some way of lowering the centre of gravity to make it more stable.
