Anyone experimenting with using Bike in conjunction with DEVONthink may find the following helpful (a terminal setting which prevents DEVONthink from changing the name and format of Bike files):
Jack Baty’s Wiki — Using .bike files as templates in DEVONthink
For context, see this thread on the DEVONthink forum:
Can I prevent DEVONthink from changing the name + format of Bike files? - DEVONthink / Feedback - DEVONtechnologies Community
and a related thread on this forum:
DEVONthink indexing and summary of Bike highlights - Bike - Hog Bay Software Support
Once DEVONthink is set to read .bike files as a special text type (without coercion to a different pattern of HTML), e.g.
defaults write com.devon-technologies.think3 AdditionalPlainTextExtensions -string .bike
Bike’s quicklook preview seems to work well within DEVONthink:

I’m just adding a note here (after the fact) meaning that I just saw this excellent advice, particularly in the link to the Jack Baty Wiki, after I had made the error.
In short, I had indexed a .bike file in DevonThink, not realizing that the DT3 had converted the Bike file from .bike to .html behind the scenes. The result for me was that the original Bike file broke and I needed Jesse’s help in DM to repair my original .bike file

I’m just reposting my experience so that anyone out there on the Bike forum will take care and pay attention to what could happen when indexing Bike files in DevonThink. I’ll point out that I wasn’t using DT3 as a template, rather I was simply indexing the Bike files. Thus, I caution anyone out there to be careful with the DevonThink3 & Bike app interaction because assuredly, DevonThink will alter the file type and potentially break Bike.
@complexpoint has offered solid advice with the links above. Wish I’d looked at these earlier, but impulsivity often wins the day.
Thanks for these links and thanks to Jesse for the repair assistance,
