The Quota in the photo was my personal bike for a while. I ran a couple of different sidecars on it before I sold it. I will send photo's dirrect on this mount as it is not all that likley to be copied as there is not much of a market for it. If you send an email request to jay@dmcsidecars.com and agree not to post the information on the internet. We have had our products copied and made in China. It is a real issue. One product was a big enough seller that I had one person full time building it and nothing but it. If we did not have several hundered other products I would have had to lay this person off.

I think you are on the right track with the subframe Diana. Pick up as many mounting points as possible i would not use square stock but rather 1 1/4" DOM with a .120 wall thickness. Nothinhg wrongwith doing a double sided suframe and connecting the two sides. Pesonally i would be very tempted to replace the stock swquare stock portion on th ebike with a whole new assembly to insure it's stoutness and incorporate th emounts at th esame time. Upper mounts should be connected to th elower mounts. Steel plates can be formed to fit your upper frame poaaobly sandwiching the frame between plates. Just soem thoughts.
I would also investigate if it is possible to lace a 17" or so wheel onto the front. If that would decrease the rolling diameter of the stock wheel / tire combination you would benefit some by the trail reduction you would get. Being able to lock a front whele under braking means little as far as performance goes. Small contat patche slock quicker than large ones and once locked stering is lost and stopping efectiveness is compromised. The idea is not to lock the wheel under braking. More things to watch with a 21" wheel: 1) Spokes...they are long and may tend to give problems at some point.
2) Understeer. Even GS outfits have issues with this due to smallish front tires if riding with much agression. In the wet it can be more of an issue. No, it isn't a game stopper but will compromise handling from what it could be. watch it when you dip across the yellow line if apexing left turns. Yeee haa moments await when you come out of the turn under power. Contorllable? Yes. Preferable? No. Of couse if you ar enot an agreesive rider this may of may not be an issue.
Quit talking and get to work on the thing....lol.

It has 2 front motormounts, 2 footpeg mounts and a center stand to connect too add highpoints for the upper mounts and you have a subframe ground clearance with an F2 isn't going to be critical.Kurt, Claude and even Jay get paid for what they know.DB
If we had done a Quota I would post pics here. Look at Zipper's thread. He copied our frame almost to a 't' . He has been to the shop..great guy. I have no problem with that really. Heck once done no matter wher eit is made it will go to event so all can see anyhow.....oooooo....no big secrets really.

Thanks Jay & Claude!

I agree that you might not want to put too much info on high volume products that invite cloning on the internet. However, for low volume stuff "open source" makes sense, as folks freely copy and improve designs, which is good for everyone. And in countries with relatively high wages like the U.S., folks aren't going to spend a hundred hours making something they can buy for less than a thousand dollars.

Yes, you are right, I need to update info and learn how to post pics. Just moved to S E Wisconsin and am riding Hack every day, have some great pics too. Also have dog that loves hack. Will do my best to make Bigfoot Rendezvous.
