GMC Motorized Road Bike

Lets see what happens so far this is my first motorized road bike. The previous one was a mountain bike.

Anyone know where i can get a cheap thumb throttle. I really need one for this setup. The one that mounted on the handle bar doeasnt work to well on this type of bike.






:cool:
 
i would mabey sugest some differnt bars anyway those look slightly uncomfertable imo

but -- they do look fast

that's the difference between 26 and 57 yrs old

how far we can bend it over or straighten it out --- well - I think you know what I mean

another note -- looks like your cables run under your motor mounts ???

a very nice looking MB you got going on there

makes it great when we wish to -- Ride That Thing
 
hardware

the back mount is the stock setup. the bottom mount are some u clamps from B&f marine, along with the matching nuts and lock washers from home depot. The metal flange between the motor and the frame was drawn by me on cad and fabricated (i cut a piece of steel and drilled it to work with the u clamps). The mounting pads were left over shock bushings off my corvette shocks.

Today i should be getting a 36t sproket and the rear clam shell adapter. the only little problem is that i gat slighty more vibration than other bikes i have built and i think its those rubberized mounting pads that i used between the engine the u blots and the frame.

cool. i should also be getting a 36t sprocket today for my chopper. but i wont be able to put it on till this weekend cause im in college in a different town. I also get a little vibration still with my rubber strips around the mounting bracket. i figured that the rubber would make it better. why do you think it made it worse?

The smoothest bike I have is actually my first very ghetto build mountain bike. Everything is mounted directly to the frame metal to metal. The bike looks very ugly just because it wasn't a new bike and I didn't care for it to look good, but it rides super smooth.

Dude sorry to hear you go to college in another town, I go to school to for my masters but its very close to home....the down side is that I have to work, so my time to fool around with the bike is a bit limited.
I am going to try to remove those rubber pads and replace them with wood . Later on I might try to fabricate something a little more professional in the cnc mill we have at the school lab out of delrin plastic.

what are you getting your masters in? sounds like some of the classes i have. im majoring in machine drafting right now and might go to get my mechanical engineering degree. i also have a cnc class and im trying to decide what i want to make when we have time to do our own stuff. let me know how the wood works out.

I gaduated from my bachelors in architecture in 02 and last year I began the masters in architecture after several years of working. The school has undergone many technological advances since my graduation in 02. They focus several classes towards digital fabrication. This includes designing in programs like CAd Rhino maya and 3ds max and fabricating the components via the laser cutter, the 3d printer (very cool for protypes) , or the cnc mill. Alot of the classes are geared towards looking at innovative ways of improving on you typical boring box with a window.

For example one class this semester we were given an "artichoke" asked to analyze it and create something that related to the human being and study its performance. So I developed a shelter structure very similar to a bus stop but way radical.

In a way both of our degrees are similar in the sense that they deal with final product that must perform, it just my degree creates objects that are a little more abstract and (maybe less practical / econimical)
