From EVtodd on my Frankenscooter thread:
Not to be an ass but that kind of sucks. I don't remember the exact details of the contest but didn't you get Matt's drive for free to build that original design? Maybe the drive should be sent back to Matt so he can run the contest again. Heck, I'll build a version of your "super commuter".
I was really hoping to see what you came up with. I voted for you! I demand satisfaction!!! Ok, maybe it's not that big of a deal, I'm just sayin'...
Yep, fair call Todd. Sorry to any members offended by the lack of delivery.
The contest-winning design is of course "open source", so it's available for use by anyone who thinks there's some merit in it, but note it is only that, a design.
The great thing about ES is that there are so many different approaches for members to reach their various goals. It doesn't always work out as we first hope it will. My present (more humble) efforts are aimed at getting this drive running one way or another. The following is not intended as excuses, but this is simply my evaluation of whether or not the Supercommuter would work for my existing MTB:
A RHS drive setup would cost an extra $500 (dual-drive, shifter, two WI freewheels), and this would reduce the available pedal gearing ratios, a sacrifice I'm not prepared to make. I had a couple of attempts at getting a LHS drive setup going. Firstly I machined 2mm off the top-hat adapter, but still the disc rubbed on my frame. I do not want to risk frame failure by crushing to provide clearance. I also discovered that the calipers did not clear the adapter either. So, I wouldn't be able keep the existing hydraulic discs. Again, it would be a backwards step to go to v-brakes on the rear. At this point, I didn't proceed with work on the drive setup.
The bike I had intended to install the Supercommuter on is presently still running the Grinhill Mk2.
