I am about to start a DIY build of a street fox and would like to put an A-frame front suspension on it. I have some ideas as to how it could be done.
Are there any drawings plans or measurements as to how it could be done?
Is there someone out there that has done this?
If there is any interest in this idea I could lay out my ideas and see if I can get some feedback as to what will work and what won't. RandyR

Don't forget that any front suspension will allow the trike to lean outwards in a corner. You can mitigate that by keeping the suspension movement small or go the whole hog and make it lean.

The picture you sent is interesting...do you have more pics of this trike? Is this your bike? I have seen quite a few pictures of A frame front suspensions but not any plans .

There's some pictures here


The original thread was on the old forum and has gone. Yes, it's mine. I built it. This one leans and it was very difficult to make it do that. There's a lot of compromise in both the suspension and steering to achieve that. I have a few more pictures if you want them - message me an email addy and I'll send them to you.

One thing that I've thought worth pursuing in A frames is the use of composite leaf springs as both the A-frame and spring combined. There are a few trikes out there using these.

Azub Tri-Fly uses a set of titanium leafsprings. But those are 1 piece top and bottom, and I know why. Team RCC (Robot Wars) uses a simular idea for the smaller machines (30lbs and 15 lbs) with HDPE blades. And why composite armor is rare in Battlebots/robotwars.

And I'm tempted to copy the idea. Titanium is expensive, but with this Dutch supplier, it isn't as bad. (yes, they do P&P abroad)
