Beautiful work! I'm totally new to the board, and I'm thinking this could be a good build for me! I have a Trek 920 Cro-Mo frame that is itching for something like this. I'm guessing HF means Harbor Freight as in you bought the 79cc motor at HF?
Is that belt trans an add-on?
What is your approximate build cost for this baby? I want to make one!
First off, welcome to the forum....you've come to the right place!
And secondly, why thanks....it was a joint effort for a good friend so he could ride with us! Yes that is the 79cc Harbor Freight motor with an added on EZM belt trans. The approx. cost, not including the bike was right around $600. This cost includes the engine, the tranny, HD built wheels, wide bottom bracket spindle, chainring, wide cranks, tires, hardware, saddle, baskets, the exhaust system and a few other things, excluding labor.
I will let you know, and not to discourage you, this is a fairly challenging build, even for a competent and expirienced builder. I actually recommend you do a build like this in that once you've successfully built your Trek with this engine, you'll have a good sense of accomplishment (the bike will rock), and any kit type build would be a breeze there after.
Some obsticles you will encounter with this build will be mounting the engine in the right place in your particular frame and getting the tranny to mate properly to the engine while getting proper chain alignment. Disconnecting the governor and rigging the throttle to the carb. It's really not that tough, it just take some thought and patience. All the problems you might encounter have already been dealt with on this forum so the answers are here as well as very helpful people....don't be afraid to ask.
Go for it and have fun! Take your time and make it right.....you'll be happily rewarded. Cheers!
