I worked with a shop that was a Rocky Mountain/Trek/Norco dealer in the mid to late 90's (been wrenching since i was 14) and worked with the guys from Rocky as their 'Frorider' team was taking effect. Name drop time... Brett Tippie, Wade Simons, Richey Schley, to name a few. Moved from there, got married, moved back to town, worked at the Bicycle Cafe with an awesome couple of people and worked on free riders to road race bikes and everything in between for Graham Agassiz and Matt Hunter to B.C. road racers bikes to paraplegic hand cycles and wheel chair wheels, (I love building wheels). Well known in the bicycle mechanicing circle here. They were fun times, now I'm taking over my dads stuff, it's fun, always a challenge, still haven't figured out how to add more time to the clock so I can get stuff done on time though, the joys of custom stuff.
Thanks, any mountain bike questions, fire away, hahaha, i haven't forgotten.

Great have you ever seeing the Nicolai-G-Boxx bikes

They use to look like this using a 14 speed "External" Rohloff hub as a gear box


Now the look like this, Nine speed Integrated gear box at the crank, such a amazing evolution



Ps: Building wheels is one of my favorite things to do in the whole world, Including BMW GS wheels if I have to do it

Questions:

Ok, I have a couple of questions about this sidecar hub setup if you don't mind...



I am a little bit confused about the adjustments.

It appears that you have provided provisions for being able to adjust for both Camber and Toe at the sidecar hub, but I get lost about how there is any freedom of movement for the Toe adjustment.
I can see the pivots to allow for the Camber, but for Toe it appears that the hub is fixed and would not be allowed to rotate in that axis.

Or am I missing something?

-----

Also, is the Unit Hub that you are using from a particular make/model of vehicle, or a generic unit?
What is the bolt pattern on them?
How much do they cost?
It looks like they are set up for a drive shaft, correct?

Thanks in advance for your help!

no problem, the two 'pivots for camber adjustment are poly-urethane with sleeves inside. The toe in adjustment at the hub needs to move such a tiny amount because we are changing the actual wheel location instead of the conventional method of re-aligning the complete sidecar frame. The smallest movement here makes the toe-in, measured at the front wheel, a large amount when measured there. The poly bushings are capable of moving that small amount and because they aren't pivoting constantly like they would do in a a-arm or leaf spring, they get held in place by the tie rod toe adjuster, can't go anywhere and all the small road vibrations that would transmit through a rod end or uni-ball are somewhat taken care of being dampened out by having the wheel isolated from the swingarm, and the swingarm has poly pivots as well. Hope this answers your questions. It is a little bit of abuse on the bushings there, but think of the loads they would see on a flexed out leaf spring, not even close to what this is having to do. Thanks for taking the time to look through the pictures.

missed your second question about the hubs. They are unit hubs for a Chrysler Sebring of all things, why you ask, they fit the best out of all the different mounting bolt patterns. The bolt pattern is 5 on 114.5 I think, I'd have to double check. Turns out to be the same bolt pattern as the ZX-14 front brake rotors being used all around and as fun as parts sourcing is, it shares the same spline as a Dodge Dakota front CV joint from the 4x4 trucks which has a companion flange mount instead of a spline stub which is way harder to mount to. It all worked out great, things fit together good and will be more than durable enough for the power and weight of this machine compared to that of the trucks and cars the parts have been sourced from.
Another note, I got the sidecar suspension and tilt all done today, pictures will be up on our site tonight, I may post one in here too :)
Check back often.
Thanks to everyone,
Brock Smith

tilt adjuster

Brock,

Amazing weldinfg and fabrication!! Truly.

But isn't you electric tilt motor mounted "upside-down? Rookie question, but I thought this same set-up gave EastBloc fits when Dauntless did this on his hack.

I have to agree that this setup is very Sexy!!!

As far as the actuator, I don't think there is a problem with this unit, as it is actually a fully sealed unit designed for wet locations. Unlike the cheaper unit that Dauntless was using (still is???).

It is the same unit that Hannigan uses on their sidecars. You can see it here mounted in an even more vunerable location in the front half of the wheel well where it gets all the water/slush/debris thrown on it off of the wheel.


One thing which you can see that I did was install some neoprene shock covers over the shaft on the actuator as well as over the shock on mine because I ride all winter and get all sorts of salt/muck thrown up in there.

But after three winters' worth of riding the original actuator is still going strong... And I have talked with other Hannigan owners who have never had an issue with their TILT actuators.
It is all about the builder using the correct parts to begin with...

It looks like Brock knows what he is doing!

Thanks for the info!
I asked because I have a Black Project on the boards right now, and need to source some hubs that can be driven. But ideally, they would be splined to work with a Ford Fiesta/Escort driveshaft.

Wish you were closer to Wisconsin, I would just contract with you to do the build after I gather the pieces...

Wisconsin isn't far, Australia is far. People bring us their stuff from all over the place, it's just if you're willing to travel. I can always come and pick it up, it's cheaper than coming out, taking time of work, traveling home then coming back to get it when its done. i pick it up, build it, you fly out and get it and ride it home. I drove 4000kms round trip to drop off our South American travelers in San Fransico in December to continue on their trip.
Thanks for the actuator reply, The Enerpak's are great, very durable. I think I have only seen one or two ever fail from useage, and they were used a lot!!
As for the hubs, find some unit hubs from the Ford Fiesta then. As long as it from the new ones, the old Fiesta didn't use unit hubs. Time to make some good friends at the local parts store. Mine let me wander through the huge warehouse searching for just the right item, as long as I put back in the correct spot what I don't need, hahaha. Inventory nightmare!

Best of luck on your project.

Looks like your swing arm is flexing nicely to let the inside sidewall polish up the arm . You need to slow it down in the corners I think , hahahaha.

Me corner hard???

That swingarm is actually pretty rigid, It was more an issue of Hannigan trying too hard to make everything fit tightly together and then going with a relatively wide tire for the rim they used. You can see how close the brake rotor is to the swingarm, and also see that it was rubbing on the actuator and its' lower mounting bolt at the front as well...
Just really tight packaging in there.

What I did was go to a tire that is one size narrower, and have not had any problems since.
In the winter months I go with an even narrower trailer tire/wheel package which gives me less rolling resistance out to the side there, especially when breaking through fresh snow or deep slushy stuff on the street. (But has been reported to give a harsher ride for the sidecar passenger.)

Ya, I know they are tight, and a thin wheel spacer pushes the wheel out too far and it hits the inside of the wheel well, oh well. hahaha. Happy trails!

Hey Brock I'm curious about something...

Have you ever made a "All you can eat" outfit. You know a All terrain, All weather, No excuses, No limits, two wheel drive kind of machine, if so, do you have pictures of it, specially after a bunch of miles and bumps on the road.

Thanks

ricky
