To wit, friends have sent photos of a couple Tron-inspired bikes they've come across. They pay homage to varying degrees, and truth is if we fall short in our VFX budget maybe one of these babies could take up the slack. With the right sound effects it just might work.
Here's one found at IGN:

That one might also satisfy the hardcore fan (or even the softcore fan), but it seems to be about 5% loosely-connected Tronware and about 95% Tron Guy wishful thinking. However, at least now I know what those stem pads are for.
Also, today is a major milestone for the Bike Date blog and the entire Bike Date corporate family. We received our very first offer of free bike product to review. Yes, Bike Date is now "Big Time", and obviously this vendor can surmise the soon-to-be-established promotional power of the "Bike Date Bump".
Our accountants are currently looking into the ethical and tax implications of accepting in-kind, quid-pro-quo, you-scratch-my-back-I'll-scratch-yours "review items". Obviously Bike Date's attorneys assure the various interested RICO investigators that graft promotional materials will be handled within the appropriate legal framework.
An honest review of these products will be posted once Bike Date R&D has conducted their thorough testing. Those guys are relentless. I know our readers expect nothing less.
