Popular Post Matahalii Posted June 2, 2018 Popular Post Share Posted June 2, 2018 (edited) Hello Folks! Since I got my Ninebot, I was asking myself how to carry luggage without a Backpack that will hurt my shoulders. I had an idea and built it yesterday. The Video shows the second ride. In the trailer I was carrying a 5kg canister of fertilizer for the flowers. Some details must be improved but all I wanted at this stage was a Proof-of-Concept. For instence the towing beam is very low as you can see it pushes the hoses over the grass. But works on flat-level street.

meepmeepmayer Posted June 2, 2018 Share Posted June 2, 2018 Brilliant! I think someone did something like this before, but can't remember any details. I'd say the natural end for the towing beam is at the rear top of the wheel. This way if you brake, the trailer is pushed backwards instead of getting closer to the wheel which it would if it were fixed to the rear end of the wheel.

Matahalii Posted June 2, 2018 Author Share Posted June 2, 2018 I thought a lot about the "Neutral Point" and came to the simple conclusion that the exact middle of the Wheel is that position. Of cause you can't attach something there. If you move the point back/forth it will affect mainly the cornering. Hitch in the back means Accelleration in curve will twist the wheel to straight, braking in curve will twist inwards. Not very safe, because the driver must compensate that. If you move the point of attachement sideways accelleration and braking means pushes to side. If you move the point up/down at accelleration/braking the trailer will have influence over the ballance that is hold by the electronics. And last but not least you got to go with the sturdiest point you can find. And you must get around the room you need for your feet including getting on/off. This way I took the hole for the pinscrew. It is about 6cm (2,5inch) sideways off the center and about 10cm under the axle. Forth/back Movement is compensated by the electronics quite well. At braking and accelleration you can feel a tiny little push sideways but it is well to handle 2 1 Quote Link to comment Share on other sites More sharing options...
Matahalii Posted June 9, 2018 Author Share Posted June 9, 2018 Proven the possibility of towing with a simple screw-through-eyelet, I refined the hitch today. I ordered a de-attachable ball-pivot M5 with securing-clip, which replaces the worm screw for the bolt of the footpeg on one side. The ball is 8mm. Then I installed a stronger steel rod to link the pivot with the side towing bar. I gave it some important bends to have the biggest avaliable freedom for tilting in every direction and also cornering. I will have to replace the Aluminium-L-profile towing bar with a square-profile for stiffness. The width of the axle is not wider than my feet on the footpegs of the Ninebot. So for straight driving I will not have to worry about the trailer hitting an obstacle. I tested this with 8kg of load in the garden (lawn) Details: 1 Quote Link to comment Share on other sites More sharing options...
