Another Crust Evasion is electrified. The initial component compliment is as follows, and will no doubt change after a few longer distance rides:
For the drive side chain stay, the frame has a short length of flat stock - fairly common on cross or mountain steel frames these days, I think. It'll clear up to about 42T (tested with a BBSHD 42T Luna Eclipse and a BBS02/BBSHD 40T Lekkie - overkill for the tiny CYC Photon secondary gear case):
August 2024 update: This bike is rarely ridden, so it's time to rethink its mission/configuration. I'm considering higher sustained speeds (forties), via changing the rear dropouts back to 148 boosts and then converting the drivetrain & wheels to a 72-volt powered Grin All Axle hub motor laced into 26" Velocity Blunt rims with "smooth" 2.5ish wide tires, and a microSHIFT super short 9-speed drivetrain. A spreadsheet cost workup, with quality parts (approx. $3,150) relegates this idea to the way-backburner. The Grin motor kit and a high-capacity 72-volt battery alone cost north of $2,000.
