The top tube extension is ready to braze. It took lots of filing by hand to fit the tubes. It’s important to make a very close fit. I positioned the existing water bottle bosses so they can be used for mounting something to the top tube extension.
So what’s left to do to finish this electric bike? After I finish brazing the extension I need to fabricate the battery box. Once the battery box is mounted I can reassemble the bike and give it a test ride. If everything works out, I’ll disassemble, prep and paint.
I also need to order longer cables for the brakes and derailleur as well as a longer throttle cable. Waiting for parts can slow a project down so its a good idea to plan ahead and order parts as soon as possible.
