Electric goped/mini bike

[Wjoinieis]

Hi guys this my is first post and i want to build an electric version of a riot goped/mini bike here is a link if you have never heard of it before http://www.amazon.com/Go-Ped-Powere...iewpoints=0&sortBy=bySubmissionDateDescending it seems like an awesome little bike but its way to expensive also it's gas which is illegal in the country I live in to drive on public roads. I did a little research and found that its way cheaper to buy a kit instead of buying all of stuff for a electric motor by itself motor, speed controller, throttle, etc. so I did a little more research and found this kit http://www.monsterscooterparts.com/24-volt-650-watt-motor-controller-throttle-kit.html from monster scooter parts I don't know if anyone has had experience with them before? I plan to make the frame out of wood just because of the fact of how much easier it is to work with
Thanks all comments are welcome

P.S. how much speed can I expects?
P.P.S. what gearing is best for speed?

that frame... made of WOOD?
Top speed is calculated by the friction between face and asphalt.

Steel instead can be calculated by rpm of the motor, the gear ratio and wheel diameter.
So make your choice

ahhhh i look forward to aother wood topic

And to add above, there is a time factor variant, usually set at the start from 0s to ~s, every "machine" is different...

The easier to work material is usually inversely proportionally to the safety factor of the material.

Equally speaking, metal and wood moving parts have a hard time working together.

What country are you from?

America sorry if my spelling and or rammer is bad I am only 14. I don't get what the big controversy over wood is it is lightweight, strong(ish), easy to work with, and easily replaceable if something go wrong. What are the best places to get wheels I thought maybe from an old kiddies bike or something that I can find cheap and hopefully it will already have mountings for a sprocket.

The problem with wood is that it is NOT strong, and it will splinter all through your body when you have a crash.

There is nothing wrong with wanting to build a kart, but we generally try steer people away from wood

(Not another wooden kart)

Wood is a great material, and you can make fantastic things out of wood.
wood can be lightweight and strong, but it's not anywhere strong enough to make a flimsy frame like the one you showed us.
I don't say it will not work, but to make it work, it is far beyond "easy to work with"

What you need is a self made plywood, with at least 7 layers, where each layer is calculated exactly for the forces that the part has to withstand.
The press to provide the right amount of heat and pressure alone to fuse the layers will cost more to rent than the go ped riot itself,
Then you need to figure out what wood is best for what task (poplar, ash, oak, pine, maple...) in what layer thickness, at what angle in which order, the result has to be flexible enough to compensate for hard drops, it has to be strong enough for all the applied forces (weight, acceleration, braking ...)
And they change at least three times for the front swingarm alone.

Even if you can calculate the layers correctly, you will have to source the perfect trees to fullfill the task (density, humidity, grain, knotholes).

Wood? Yes, great, if you know exactly what you're dealing with.
And I'm sorry, but you don't.

picture this:
You made a wooden frame, attach a 650W motor and are on your way on a loong downhill road,
all good, all easy, great fun.
suddenly a sinister roar from the left you steer right hit the curbstone and the front swingarm breaks, without warnings, no frontwheel at 30mph...
So make sure you have your camera running for your personal youtube moment
