New MBB

Original from 8 years ago

New trike to be like on this one with a new front end.

Stem for 31.5mm handlebars holds bottom bracket cartridge with threaded cups removed. I originally used this type of stem here.  You can do strange adjusments with it, like quickly change the bottom bracket height and sideways position

A few parts. White forks donated the head tube bearings for the new bike. Centre part is timber frame for front of trike with bearings. Black fork will be used on new trike.

Hammering the wooden bearing holder into aluminium rhs frame

All the parts

Parts in place, testing transmission.  The cranks moves with the steering.

Frame clamped to plywood board for testing.

Hi

Several years ago I, had a go at making a moving bottom bracket front wheel drive bike based on a fixed bottom bracket bike I had made. And now years later simple leaning trikes are my recumbent of choice, and I am going through roughly the same process, making a new trike this time, but with so many old parts lying around its not really all that hard.

Pics above show progress to date, I'm quite pleased!  With Melbourne in coronvirus lockdown more than the rest of the country, I have to do something to keep the brain ticking over. Will report more later.

Regards
