The new front was based on the Speculoos, but if you have a link for a Flevo - mini - Racer, I would be keen to see one...
a small picture is attached...
BTW: how high was your bottom bracket from the ground. Having your BB to high would also cause wheel flop.
the BB-Seat Diff. is 25cm.
After re-reading Jürgen´s "Frame Geometry"-Page, I think, the Wheel Flop is also established in this: "The optimal pivot angle is exactly the one where the weight of the whole front part (including the riders legs) is in equilibrium with the rest of the bike (including the rest of the rider). This is different with every bike and rider. To be more exact: It is the angle where the wheel flop effect is nullified by the seat rising effect." I think the Pivot Angle at my trike is too low.I thought Jukka's comment relating trail and seat hight, was also interesting.
Trail -27 cm and seat hight 30 cm.
This would have been a issue for the Rev B design. I actually made that change to the original Jetrike (now Rev C - Photo Attached) because I found it saved weight. The Rev C is 2 Kg lighter than Rev B, just from squeezing the frame in.
Ok, that´s a fact... How would you couple the rocker arm with the swing arms?
Which Program do you use to create your drawings?Solidworks -- it took a while to learn, but now I seem to have the hang of it. The best things about it are: - it is parameter based, so you can change your mind, alter a dimension or angle, and it will update your drawing, - it supports weldments, so you can have all your structural member profiles, draw your frame with lines, and then select the profiles you want to apply to those lines, - it does the whole cut list thing, so you can find out how much metal you will actually need.
That sounds like the Office Premium version? - Wow! - Mark
