Hi all,
I built a Street Fox about 6 years ago, but never really got much use out of it because I found it just to heavy for the hilly conditions around here. I was planning on getting it bnack on the road again this year and low and behold but didn't a storm come along and collapse the shed it was in on top of it. This damaged the back end but most of the structure survived.
So my idea is to use the existing frame as the basis of a complete rebuild. My idea is to cut out the difficult to fabricate bits and use them as end bosses for a glued and riveted Aluminium stock rebuild. My framing is 40mm square so theoretically I could use 45mm square aluminium tube and mount it on the outside of the existing steel "bosses". Given a 20mm overlap and PU glue (the stuff used in car body paneling) and then rivets on all four faces. This should afford sufficient strength and act like a brazed boss. I would have to replace the back forks with an aluminium set of forks as this is where a lot of my weight problems come from as I used a real cheap Chinese donor bike.
At some point in the future I would like to add either a 250w electric hub motor or alternatively a nice 4 stroke petrol. The design would have to account for this extra speed potential and I was never happy with the utility of the front side pull brakes which would often allow the back end to lock up way before the front two engaged. So I would look to some sort of brake upgrade at the front - center pull at the least.
So just shooting ideas out there at the moment.
