The nice thing about the front suspension is that I have now the clearance to install some fat tire at the front.

Last year, Schwinn introduced a 20" fat bike for kids:

It was actually cheaper to buy the complete bike compare to only buy a set of wheels from Schwinn...

Sadly, the KMX hub number of holes didn't fit the fat rim. I had to build my own hub:

Once the new set of wheel is trued, it is time to install em on the bike for a test:

Wow, what an amazing machine Adam. Your engineering skills and precision fabrication are simply astounding. With all the CNC milling and 3D printing, is that what you do for a living or is it just perfection in your hobby!

I love your new suspension - Is bump steer and brake steer a lot worse now that the king pin axis doesn't hit the ground where the tire contacts the ground? Or do the new larger diameter wheels now bring the contact patch much closer to the king pin axis again? (hard to tell from the photos)

I do mechanical design on computer at work and I have a CNC lathe and milling at home.

On the 16" KMX wheels, the bike is really stable at low or high speed. But yes, on those fat 22.5" tire, I have a non zero scrub radius. The bike is definitively harder to steer and less stable at high speed. It also become important to balance the wheels.

Very nice job Adam. Beautiful Trike.

I'd upgrade the motor controller to a Sabvoton or one of the other sinewave controllers, much nicer control on my Borg's Cromotor since I did that.

I'd also add a ham radio, with the trike you can carry stuff and have some radio fun! (At least while parked, the RFI is probably bad when motor is engaged.)

Enjoy!

That's a shame. Wouldn't want to hit a pothole or kerb at speed with one wheel I imagine. Direct steering no doubt gives you less leverage to handle the peak loads as well. Tricky.

So, I hope you have a matching green rim planned for the rear wheel just to get the look perfect? :-)

The old flag "flapping" noise was really annoying.

I was told that making fringe in the flag with a blade would improve that. It is true, but the flag get ugly quickly.

I then made my own flag : ( new vs old flag )

Latest flag version completely noiseless:

Love the new look, now its angry and mean looking with a wide stance. And in the dim light in the video that windwrap and those low hanging lights really make it stand out in a positive way.

Man that "flagpole" is a torn in my eye. Great looking trike, and then a flagpole in the back? A nice bright rear light would looks so much meaner.
As it is that pole kind of take away that bad boy look you got going there, flag poles kind of makes it mix of bad boy and accountant trike. :)
Those poles are mandatory? Like a fine if you get pulled over without one?

hehe, thanks :)

No, the flagpole is not mandatory, but the trike is so low that I almost got me killed 3 time from cars that "didn't saw me".

Since I have the flagpole, It is no longer an issue.

Hi! What did you use to mount the cycle analyst? I'm looking for a solution on my kmx recumbent.

I made this bracket in Black Delrin:

Then i tapped 2 holes on the KMX boom tube.

I can make another one if you are interested.

That problem is why I abandoned my first (and only) lowracer build, and developed the semi-recumbent CrazyBike2 instead, and stuck with "car driver height" seats after that, simply to ensure visibility (and my ability to see around cars, rather than having to look under them ;) ).

Around here, the flags and such don't really work--if you can't be directly seen, you're probably just a "construction sign" or something that can be run over with impunity. :(

But if you're bike/trike is big enough they might hurt their car when they do it, they're less likely to. ;)

My daughter is growing up. It was time to adapt the KMX to accept the Trail-a-bike.

Nice job, You might need some kind of mud guards on the back wheel of yours to protect her
