Glad to hear you had a chance to test the suspension and you enjoyed it for this first rideThe Toecutter wrote:As of last Friday, I had air in the shocks. I tried them at 90 psi. I've put 29 miles on them, with a maximum speed of over 25 mph, purely under pedal power thus far.
I am impressed with its capabilities and I am of the opinion that I have gotten what I paid for. I can go over potholes at 20 mph and it feels like I'm in a car, provided I keep the rear wheel out of it. The feedback during steering is valuable and gives me a subtle hint whether or not I will flip if I introduce even more Gs.
I also had this kind of issue with other bike in the past... I never understood why jealous people feel the need to destroy uncommon cool things...The Toecutter wrote: I would have done more testing, but I parked it at a grocery store earlier in the week and found that while I was inside someone had damaged the spokes on one of the front wheels. I had to have the wheel re-built. I will be putting the trike back together tonight, and ride it more tomorrow.
1) The suspension was designed to use Bengal brake : http://www.bengalperformance.com.tw/mechanical.htmThe Toecutter wrote: I do have a few questions:
1) I am using Avid BB5 cable-pull brakes. They do not line up flush with the suspension kit as shown in the manual. I am guessing that they were designed for hydraulic brakes instead? Anyhow, I used spacers to get them to work, but no such items were shown in the images in your manual and I would like everything to line up perfectly.
2) Over the long term, can I expect the shocks to retain their air pressure? I need to know if a pump dedicated specifically for this suspension will be a necessary component in my tool kit for long distance riding.
3) What is some of the worst abuse that you know of that the shocks can withstand? I'm just looking for a general idea of what I can expect of this suspension if I'm flying down the highway at 55 mph and hit a large rock or chunk of brick with one of my front wheels.
I will place an order for a set of Bengal Brakes later on today, and get a picture of my BB5s sometime today too(Have to charge my camera).1) The suspension was designed to use Bengal brake : http://www.bengalperformance.com.tw/mechanical.htm
Would you mind show me a picture of the brake alignment with the Avid BB5?
That means I will need my own compressor then, but not urgently soon. A simple hand compressor for motorcycles might be a good investment.2) Well, I tested the air pressure after 6 month and I lost roughly 10 psi from each shocks. It wont be needed for long distance riding but I would recommend testing the air pressure every 6 months.
That is what I was hoping to hear. It appeared that way before I ordered it based on others' experiences with the kit, and seems to be very sturdy based on my usage thus far. The availability of your kit and its existing 3rd party usage cases have convinced me the KMX would have met most of my requirements without having to go full-retard and build my own chassis completely from scratch, and I am not disappointed with this investment at all. A body is going on it soon.3) The suspension was designed to be very robust. There is a lot more chance to damage the front wheel if you hit a rock or any obstacle at high speed.
Hey guys, almost 7 k miles on the suspension.... working well...adam333 wrote:Thanks for the feedback.
Ya, this is also the part I dislike about those steel Shoulder screws...
You could also brush em with a steel brush to remove the rust. Be careful not to reach the aluminum though.
It is also possible to use S.S. screws but they are expensive: ( an extra 145$ )
2 x 90263A176 @ 14.51$ ea ( 316 SS Shoulder screw M8 x 35 )
2 x 90269A156 @ 15.98$ ea ( 316 SS Shoulder screw M8 x 40 )
16 x 97345A621 @ 5.34$ ea ( 316 SS Shoulder screw 3/8” x 5/8” )

Yes, so far so good, and we just moved, so my commute is now a mere 3 miles to work, therefore the mile racking won't go as fast as it used to go...adam333 wrote:You sure put a lot of mileage on this trike. Glad to hear it is still going well

I have more recent pics on another device. I'd say as of today it's about 80% complete. The pics in that link are the progress from months ago...
My testing with the body has been limited to around the block. I do not want to damage it and undo my hard work. Doing 35 mph downhill was totally unfared with ample amounts of leg power(and probably a tailwind too). The suspension performs well even at that speed.
Once the body is on it, it will be time to do the electric conversion... then I can really put things to the test. I very much want to feel how this suspension performs at 45-50 mph. I have high expectation based on how your suspension has done thus far.
I've upgraded to Avid BB7s two months ago. Stock BB7 rotors though. Are there any that you would recommend? Your build performs very well and anyone building up a KMX could learn a lot by studying it.gman1971 wrote:Suspension has worked well at 60 mph, so I don't think you'll have much of an issue with it. Brakes tho, just make sure you get decent brakes and large rotors to stop from high speeds.
Good, I've been running BB7s since mile 0 on both trikes, no issues to date. I am running 203 mm on the fronts on my A-1 trike, and 160mm on A-2 trike since its a lot lighter and my wife doesn't drive it at 40 mph like I do...The Toecutter wrote:I've upgraded to Avid BB7s two months ago.

What is the scariest thing that you've done so far on your trike where the performance of the suspension was critical to you avoiding a wreck? What conditions was the suspension subjected to during this experience, how did it perform, and how close were you to disaster?
I've gone over tall 4"+ speedbumps at 15 mph and have gone airborne from those, but I'm a lot more careful with how I approached obstacles now since I don't want to damage it. I'm confident that I could hit a 2" deep pothole at 30 mph with this thing and not wreck, but I don't want to deliberately test that, either.
