I started messing about with these things about 12 years & 150 pds. ago. I will say they
helped me get started losing weight. These days I pedal 99% of the time. My motored bike
is kinda lonely, but I start it regularly & ride once in a while. i ran the gamut of kits. Those
Chinese 2 stroke chain drive are pretty much trash. Their 4 strokes aren't much better,
too many moving parts. The chain drives are dangerous. If not very precisely installed,
the chain can jump & lock up the wheel. Not good at 35 mph, which is faster than a
regular bike is engineered to go under power. I finally settled a a high quality Japanese
2 stroke,(EPA & CARB approved), with a friction drive. It is my bug out bike & hedge against
getting too old to pedal. The rear wheel shown was for an optional belt drive I've abandoned.
It will do 26 mph, but I prefer to stay between 16 &18. 140 mpg. When electrics get that
kind of range, I might buy one.

Aaalright I think this is the right thread to post my question... in short, I'm looking for a 26" rigid front fork, 1" threaded headset... WITH disc brake mounts!!!
and I'm starting to think that doesn't exist.

The long version is: I got a mid 80's mtb for free off of craigslist and threw on an 80cc Chinese suicide machine, had an absolute blast, but yeah nearly killed myself... twice. first ride the (probably original, yeah I know) tire fell off. Third ride the rear rim started resembling a washing machine with a brick in it, rendering the rear brake useless. Not that it did much anyway because of all the oil spitting out of the engine. fourth time one of the bolts for the engine mount fell off, engine tilted to the side and the drive chain got in the spokes. Seriously, it was a lot of fun... so now I have mag rims off of ebay, that might hold the weight a little better, but I have to upgrade to disc brakes. anybody I ask usually says not to weld to the frame and brazing wont hold the forces soo... any ideas. buying a new frame usually just brings its own set of problems, mainly that the engine never fits

You can weld mounts on a steel fork AFAIK, but would need to repaint them. The front is responsible for 70% of the braking forces, so a front disc should suffice.

Germans had wood powered V dubs during ww2. This steam powered unit makes me think of a wood powered bike...
