Here is my Sidewalker micro electric.

Hello mate. interesting build. I have bought same scooter for 15usd and was thinking usin hub motor but i needed speeds around 30kph. my question is, how did you mounted the sprocket on the wheel? was the freewheel strait fit? is it enough power or do you kick start first? would you use another motor/controller if had to build it second time?

What's the hose clamp for?

The 80 tooth sprocket is mounted on the 16 tooth sprocket of the rear wheel. The 16 tooth sprocket is mounted on the free wheel.
The 16 tooth sprocket is mounted between two nuts: 80 tooth sprocket - nut - 16 tooth sprocket -nut.
The rear wheel is positioned at 1 cm left of the longitudinal axis because otherwise there is not space for the chain and sprocket.
The motor is powerful enough to start from standstill, but I find that a kick start is more comfortable.
For a second build, I would use another sprocket for the motor. Instead of 11 tooth (33km/h) I'd use a 14 tooth (~42km/h).
For the rear wheel I'd use a scooter rim. I'd try http://tncscooters.com/index.php?route=product/product&path=62&product_id=236 with a freewheel assembly: http://tncscooters.com/index.php?route=product/product&path=63_114&product_id=389

I need the hose clamp to tighten the 80 tooth sprocket on the 16 tooth sprocket because the screws don't fit perfectly.

I see you are using a coaster brake wheel on your scooter. If you use a threaded freewheel hub instead, you can use one of the four-bolt flanged freewheels that's available for those. You can't use the coaster brake anyway, so you might as well ditch it.

So basicaly u would fit freewheel assembly on to the rim and then 80 tooth sprocket would fit directly on to the freewheel? which sprocket have u used on. the rc motor? is there direct fit or you need to make an adapter. also what do ya think about those band breaks? i thought if i can get all the stuff from one place would save on expencive shipping.

What do you think about this setup for the rear wheel:
Wheel assembly: http://tncscooters.com/index.php?route=product/product&path=68&product_id=442
Brake: http://tncscooters.com/index.php?route=product/product&path=34_99&product_id=222
Freewheel: http://tncscooters.com/index.php?route=product/product&path=63_114&product_id=391
Sprocket 80T: http://tncscooters.com/index.php?route=product/product&path=63_89&product_id=131
Would this combination work?

Yes

which sprocket have u used on.

80 tooth sprocket

the rc motor? is there direct fit or you need to make an adapter.

Direct fit, but you need to make a hole in the shaft

also what do ya think about those band breaks? i thought if i can get all the stuff from one place would save on expencive shipping.

I don't know what to say, I don't have the dimensions

I like it!

How does your throttle work?

Nice

Have you considered painting on some liquid electrical tape? I just don't like to see exposed connections :p

Now I use a slide potentiometer held in position with a spring.

I will consider this. Thank you.
