So after my other custom got liberated from me I picked up a trail-z from Walmart out of necessity. I used it and determined that this platform was destined for a gas conversion. I've put together some parts and need 3 major components to get fab started.

The plan is using a 5:1 trans, and an 11t "8mm pitch" with a 44t drive gear on the left hand freewheel. This is very straightforward in design, all I need to do is remove the electric motor from the mount plate and attach the new 5:1trans as well as the L/H freewheel and 44t in place of the 20t #40 sprocket. I've chosen a cy46r for power, I plan on using a 2L tear drop tank and modding the carb for single feed w/o primer. This bike need a front end upgrade to be great " the stock shocks are bent from a customer running into a parked car." I think I want to run triple trees but I want shocks on the front as well as a front disc brake, but the completion of fab isn't held up by that. I want a good quality twist throttle with a killswitch, not a cheap plastic one. This bike needs to be top notch so I'm not ashamed to ride it. The 3 things I need to start deconstruction and fab are, engine, fuel tank and throttle/w cable.

Any thoughts or comments? Has any one done a trail-z conversion before?
 
Sounds like a plan. Did you give any thought to keeping the electric drive train and adding a gas engine? It would allow you to run electric power alone on side walks and multi-use paths.
 
Yes and no. The drive train is what is appealing in this conversion, making it an easy gas swap. If I were to do a hybrid it would be a 24v hub motor in the front wheel to keep weight evenly distributed. Also I loath the SLA battery and its weight. So the heavy rack that holds the battery and controller is going bye bye. And a light sheet metal HT 2L tank and twist throttle take its place, the Currie motor weighs more than the cy460r and I'm more than quadrupling the power it currently has. I'll take measurements to see what kind of weight reduction I'll get from this conversion. The 46cc engine "cy460r" has 4.2HP @ 13000 rpm :D
 
WOW just started converting one of these for my main ride and couldn't agree more they are almost made to be motorized.
 
Cool man what is your engine choice for yours? Are you using the mount plate as well? I've read that these have an inherent flaw In how the wheels are laced, they can be relaced correctly with 14g spokes. I plan on upgrading the rear wheel to 12g spokes since I had issues on my belt drive with 14g spokes and less power than this will have. I did just replace the forks with straight stockers, but I have a plan to build some triple tree shocked forks. I have some triple tree clamps from a razor mini chopper and the shocks from the bent zoom forks, if I can get a buddy of mine to make the long riser bars I can have a shocked chopper style front end for this bike but that way it still won't have disc brakes.
 
I have a Honda GX35 OHC Mini 4 Stroke on a GEBE rack mounted bike kit. I had the back wheel custom built to go with the engine so I'm moving it onto the E-zip. The only snag I'm hitting at the moment is the front fork. I'm looking for something with disk-brakes as well but cant find something in the right size. I 1/8 in threaded headset. Ware are you hearing about problems with the stock wheels?

Awesome man if you look at my avatar that is my custom gebe style belt drive on a high end Motobecane with a 30cc built Ped motor, unpiped I hit 40 and I beat two tickets I got for going too fast. That bike was jacked from in front of my apartment.
 
That looks to be exactly what I need as well i've been looking for a suspended fork with disk brakes for a few weeks now with no luck so thanks for that. Have you e-mailed the manufacturer at all? Do you know if you need any kind of adapter for this kind of bike? I'm sorry to hear about your bike make sure to keep the new one inside.
