The main Problem is with this Hub,

Because the Hub should fit to 36 spokes rims, usually it for 26' 24' 21' inch rims,

to fit 12 inch rim, it litte problem, the Hub is about 9' inch size,

so i buy simple curved sprokes rim,

i broke the curved sprokes, and i design some part to fit between the Hub and Rim, By CNC Cuting.

This is looking fabulous. great work mare. what kind of speeds/range you expect? I am just finishing my stand-up scooter project, meduza project. was wanderin if you could throw in a link for dc-dc converter. also how much was the motor/controller combo? cheers, nice project, thumbs up

[Astropower]

Thank you for your reply,

the maximum speed is about 42.5Km/h (26.4MPH) in theory.
it will depend finally on the total weight.
simple calculation.

the range i hope it will be more then 40Km (25 miles).. and again, i will know for sure only after real test drive.
but for sure, In low speed or hills, i will save a lot of energy compare to the normal scooter in the market, thanks to the transmission.

about the DC to DC, this is the item that i bought :

this is the controller:

about the motor, i dont have information on the web, it cost me about 150USD.

Thank again for your support.
