I already have all the stuff, but I've ran into a gearing problem. I think I need another 5:1 reduction on top of my 2-3 reductions...... I think I'm going to find some scooter or something where the wheels are smaller.
What about one of those inline planetary gearboxes? They usually are good for around 6:1. Maybe two of those "in series" to get a good ~36:1 ratio would make gearing much easier.
im planning on using this servo tester (suggested by brushlessboy16)
and myabe 2 orders of these for 6s 8000mah 10c for 80A cont and 120A burst for only $80
and this pinion. it has a large surface area and is cheap
now all i need is the tranny plate

You already have a pile of gear there that needs to be put to good use. Don't scrap that project so easily yet. Just take a step back and rethink your approach. With what you have there you can still make this a very cool project. You may need to go a slightly different direction with your gearing or even your drive setup to accomplish your goal, but it is still possible to get her done.
Maybe a belt drive with a spring loaded clutch assembly, or like suggested my BrianG using an inline planetary gear setup to get your gear reduction would be a better choice. There has to be something that you can do to make it work fairly well. Don't give up on it yet.
PM me if your interested in it.
443 Kv and a 50:1 reduction box.
Its the same physical size as a neu 2230.
If no i have to put this on my bike :)
Hey what voltage is that motor? It sounds like an idea that wold work well in an application like an E-bike? And where did you get it? off of some household equipment, or junkyard, or some other application? I am curious about the motor to.
heres the ratios and rpms
this is with 24t motor pinion and 54t spur with 1.833:1 tranny ratio and a 30:1 ratio from outdrive pinion to wheel/tire rotation

motor is designed to run 12v. but I have overvolted it to 36v. it can handle it. its designed to push 200lb robots. should have plenty of punch to move a bike.

There is a pot (the knob) on the end. If you turn that it will turn a servo, or the throttle on the esc. It has a (iirc) 6v or 6s lipo input. You may want to make a rubber band/spring mechanism that returns it to neutral after giving it throttle. That's what I plan to do.
